He only stepped in it because its a hot-button political topic, much like abortion.

When someone is controversial for the sake of being controversial, it would be foolish for them to not anticipate consequences like no longer being accepted in mainstream company. Or ever company one or two standard deviations of 'daring' away from the mainstream in some cases.

I get that it take bravery to do this kind of thing. (Or it could take foolishness. I'm not saying that's what happened here, but I wouldn't tell someone who believed to to be so that I had strong reason to believe they were wrong: I don't know the guy.) But being brave isn't a free pass to not deal with the consequences.

And sometimes those consequences mean you aren't able to do as much good (or as much whatever you want) as you otherwise might.

He took that risk in writing it. This site is taking a risk in continuing to associate with him. I am making the choice not to take the risk of reminding anyone not involve in Less Wrong that I read stuff here and sometimes post a trifle bit.

As an experiment, ask yourself how many dollars a rape is worth, how many dollars should be paid to prevent one. I suspect many of the posters in that thread will simply refuse to give a numerical answer. This is a clear indicator of mindkill.

Actually, thinking you can simplify and generalize human behavior down to rules like that is a clear indicator of mindkill.

Let me break it down differently, not like anyone else is going to see this since they're all in the new thread.

  • Person A is hurt because their authority to control sexual access to person B is violated.
  • Person C is hurt because their authority to control sexual access to themselves is violated.

Claiming equivalency between the injury to person A and the injury to person C is very insensitive. Hinting that person A's suffering is greater takes a few steps further. It's kind of dumb, too.

The people I'm talking about don't shy away from rape. They might have, at one point, but one of them was a student to Craig Palmer, who has been rather vilified for writing a frank book on the topic. Yeah, it's an anecdote, but it's in answer to your anecdote for whatever that's worth.

I won't address the first part of your post; I think it is largely correct. We are, after all, responsible for our own actions. However, for the second part, I don't think that anyone is even remotely trying to claim the equivalency you're describing above. It's most definitely a straw man argument. If nothing else, the first claim should read more properly as "Person A is hurt because they have become legally responsible for a new human being and half of all associated costs and maintenance for that new human being for a period of no less than 21 years, in a situation where person A is not responsible for the creation of said new human being." After all, we are responsible for our own actions. Not necessarily those of someone else. (Side note: the 'control of sexual access' part doesn't make any sense, other than to construct a strawman. I don't understand at all why you felt that to be a legitimate argument or position.)

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 88-89. The previous thread has passed 500 comments. 

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.) 

The first 5 discussion threads are on the main page under the harry_potter tag.  Threads 6 and on (including this one) are in the discussion section using its separate tag system.  Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18.

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

Public Service Announcement: If you feel strongly affected by chapter 89, and do not yet have first aid training, consider googling a local class and signing up. Some sudden deaths can be prevented, and it might need to be by you. Make the most good out of your horror and revulsion.

As far as teachable lessons go, Harry didn't get first aid training for his first aid kid. If Eliezer wanted to maximize the amount of the impact of this lesson he could let a healer tell Harry that he didn't use the kit to maximum effect in an upcoming chapter.

First aid kit as curiosity stopper. Treating it as more a checkmark on a list of things responsible people have, and not an item that causally interacts with the world.

One of the first things we got taught in first aid was "there's nothing in a first aid kit that can save a life". This probably needs a bunch of caveats to make it absolutely factually true, but it's worth generally bearing in mind. (My actual first aid kit includes a pair of trauma shears, which I think could save a life in a non-negligible amount of emergency circumstances.)
0somervta
Well, most of the point of first aid kits (and first aid training) in serious situations is stabilization, which could indeed save lives in the situation where a ambulance/professional is in the way.

This is a very powerful demonstration of how the sudden death of a single loved friend affects one more than the horrible, slow torture to death of a thousand strangers in Azkaban.

This applies to Harry - but I'm not talking about him. I'm talking about myself and all the readers now expressing their pain on reddit.

A single death is felt differently from a thousand deaths. At least in fiction...

Y'know, I like the new, true version of Ch. 85, the one where Harry fails to get a phoenix -- but I also really liked the original version (which, remember, Eliezer wrote as a stand-in because he couldn't get the true version finished in time), where Harry, compromising with himself, made a resolution that for now he would try to win without killing people -- but if anybody died [by his opponent's hands], not just a PC, but any arbitrary bystander (he'd been thinking about how Batman's ethics only come off as good if you don't care about all the NPCs the Joker kills), the gloves would come off.

I'd kind of hoped that Harry would be able to actually go through without a death, and failing that I kind of expected that it would be some random NPC's death that would change things -- but I don't think that would actually have worked to justify Harry's future actions to the reader. [ETA: I guess buybuydavis is right too that, even more importantly, it wouldn't have worked as a statement against death.] It really does need to be somebody we (the readers) care about in order to carry even a fraction of the emotional impact that death should carry.

I don't think it works if what EY is making a statement against Death, which it seems to me he is. Rationality is all fine and dandy, but I think it's window dressing on the main theme of the value of Life and the horror of Death. The best, the brightest, the most loved, the least deserving of it will die with all the rest. So, Hermione dies.
4DanielLC
There was one thing that annoyed me about this. Harry wasn't just fighting Voldemort. He barely even cares about Voldemort. He's fighting everything bad about the universe. If he was truly willing to take the gloves off after the first death, then he would have done so after about half a second.
2Benya
Actually, this is the aftermath of the Taboo Tradeoffs arc (i.e., the Wizengamot trial): yes, Harry doesn't care about Voldemort, but he does have a very specific enemy at this point -- the person who tried to murder Draco and send Hermione to Azkaban (or at least the second, if it was Quirrell -- of course I expect it was Quirrellmort, but Harry only thinks of Quirrell as one of a range of different suspects). And by the time of Ch. 85, to Harry's knowledge, nobody has yet died in that particular war.
0buybuydandavis
I don't think Harry's target is a person at all, but Death itself. That's the enemy. Harry would actually save Voldemort from Death if he could.
4Benya
If we're talking about the story as a whole, sure. If we're talking specifically about the two incarnations of Ch. 85 (which I was), let me quote: Sure, Harry doesn't actually want to kill that unknown enemy -- it is also Ch. 85 where he thinks about how killing Voldemort would make the people of a hundred million years into the future terribly sad -- but he very much does think in terms of a human target at this point in time who he wants to win against.
0buybuydandavis
Per chapter 90, I don't see him thinking about his human enemy, I see him obsessing about defeating Death to save Hermione.
1MugaSofer
Wait, that got replaced?
0Benya
Yup. It was, apparently, a placeholder because Eliezer didn't manage to write the stuff about the phoenix in time for the update (and didn't want to leave the fic hanging on that gloomy note for a long time).
1MugaSofer
Great, now I have to go re-read it. Shame, I quite liked that chapter, actually.
6Ritalin
Depends on the circumstances. For example, if you're inflicting the deaths yourself; I read somewhere that the Nazis used gas chambers rather than the bullets they used at first, because killing unarmed, unresisting individuals of all ages and genders by the dozen disturbed the soldiers. Or when you don't know the people yourself, but their disappearance impacts and cripples your world.
2NancyLebovitz
I've read the same thing about Nazi soldiers, and also that they couldn't handle another early method of killing-- driving prisoners around in closed trucks with the exhaust fed into the back compartment. It's not that the thousands have no impact, it's that one person can make a much larger emotional difference. I've also heard that for soldiers, seeing one more death or injury can be the tipping point into PTSD.
-2sebmathguy
Am I missing something, or does this follow trivially from PTSD being binary and the set of possible body counts being the natural numbers?
4JoshuaZ
The thing is that PTSD is really not that binary, like many mental illnesses, it has a wide range of symptoms and severity levels. What Nancy is talking about is how one death can push one drastically over, skipping much of the middle range where it might be ambiguous if one had symptoms severe enough to be diagnoseable. (Disclaimer, while I've heard the same sort of things NancyLebovitz is talking about, I'm not aware of any studies actually supporting this.)
2sebmathguy
Got it. I was previously having difficulty making that belief pay rent.
-3Alsadius
The people in Azkaban are guilty of crimes, usually pretty terrible ones. There's a difference between the innocent and the guilty. Edit: For clarity, I'm not saying that they deserve to be tortured to death for their crimes. Azkaban is unnecessary and wildly disproportionate. It's an issue of priorities - I'm going to feel bad for the victims of murder and work to help them quite a lot earlier than I'll do the same for the perpetrators of murder.
9RolfAndreassen
From canon, and from what nearly happened to Hermione, it is clear that one can be sent to Azkaban while innocent.
1Alsadius
Of course. However, it's not the usual outcome. Even given that, Azkaban is certainly worse than Hermione's death, speaking intellectually. But it doesn't hit as hard emotionally.
6ygert
If there are thousands of inmates at Azkaban, and the wizarding justice system is not always absolutely correct, even if then are only wrong a percent or two of the time, there are tens or even maybe hundreds of innocent prisoners of Azkaban. So, "not the usual outcome", is irrelevant, what matters is the numbers. But of course it doesn't hit as hard, and that is precisely because of the numbers. It is a bug in the human brain that one innocent person being ripped to death in front of you hurts a lot more than tens of innocent people being tortured to death out of sight, especially surrounded by thousands more people also being tortured to death who some say have lower moral priority.
-1Alsadius
I don't think it's the numbers so much as it is the familiarity. Were I familiar with any one Azkaban inmate, assuming the wizarding justice system is at least decently effective, I'd probably say "Yeah, this guy is probably guilty. Sucks to be him, but he should really avoid killing people next time". That is not what I think when I see Hermione suffering. Even knowing that there's probably several Hermiones in there, not knowing which ones they are makes empathizing with them a lot harder.
1Qiaochu_Yuan
Based on how Hermione's trial went, this probably isn't a safe assumption. Many of the people in Azkaban may have just pissed off the wrong person (e.g. Lucius).
0Alsadius
I doubt most trials are decided by political pressure. There's a few, but the typical trial is done in an ordinary way, with no bias more malicious than a prosecutor wanting to avoid looking stupid and the judge wanting to get done in time for lunch.

When I first read the end of the chapter, my thought was that Quirrell hadn't arranged the incident; he had thought it was a "surprisingly good day" which suggested to me that he hadn't expected the troll.

After reading comments, I became less sure about that; someone suggested that Quirrell might have simply not intended for Harry to be at the scene and in danger. This seems plausible, but one thing still makes it difficult for me to believe it was Quirrell.

The troll had been enchanted against sunlight:

someone had enchanted the troll against sunlight before using it as a murder weapon and might also have strengthened it in other ways.

And Harry transfigured part of the troll:

Harry visualized a one-millimeter-wide cross-section through the enemy's brain, and Transfigured it into sulfuric acid.

But before, it was stated that Quirrell could not charm something that Harry had Transfigured:

Professor Quirrell could not cast spells on something Harry had Transfigured, for that would be an interaction, however slight, between their magics, but -

For Quirrell to have been behind this, I can see only two possibilities: 1) Harry can transfigure something Professor Quirrell ... (read more)

He touched it. In chapter 56 or 55, I forget which, Harry had to wear a glove to ride the room that Quirrell enchanted. In chapter 89, he picks up the troll by the ear.

Oh snap. I didn't even notice that problem. There is a third possibility: Dumbledore brought in the troll to guard the Stone (or other object), as in canon, and he was the one who cast the spells to protect it. I'm unsure about this, because it seems unusually violent for Dumbledore.
4Izeinwinter
In canon "Troll" was defense layer number.. 5? Anyone in that deep can fairly be considered to be asking for it. If this is the case, the naive reading of events is that it got loose because someone was cracking the defenses...
4ygert
In canon, there were two different trolls: One that got in and attacked Hermione, and one that was guarding the stone. Two totally different trolls, although many have noted that both were supplied by Quirrell. (And actually, because of this it has become fanon that Quirrell has a talent in dealing with trolls. (Although that Quirrell is a very different person from HPMOR's Hansonian Quirrell, so don't read to much into this with regards to HPMOR.))
7Desrtopa
I believe that Quirrell actually stated this in canon. When he admitted in the chamber which held the Philosopher's Stone that he was the one who had supplied the troll for the defenses, he said he had a knack for dealing with them, or something to that effect.
3vericrat
Why would Dumbledore enchant the troll against sunlight if it was going to be in the third-floor corridor all along?

Hermione's cheeks were going even redder. "You're really evil, did anyone ever tell you that?"

Hermione's lips were moving, just a tiny bit but they were moving.

Time froze. Harry should have told her not to talk, to save her breath, only he couldn't unblock his lips.

Hermione drew in another breath, and her lips whispered, "Not your fault."

"Of course it was my fault. There's no one else here who could be responsible for anything."

I'm sad now.

Those of you who didn't read canon before reading this, there's a corresponding incident in the first book which I think would add to your understanding of this incident. Quirrell sneaks a troll into the school, but Harry, Ron, and Hermione are improbably able to defeat it using the first thing the Weasleys try here (smacking it with its own club). The difficulty level of that encounter was clearly calibrated to the characters' strengths in a way common in heroic stories and I think Eliezer was deliberately subverting that expectation. (He's made this point in the sequences on a few occasions - something about how it's allowed for Nature to just throw problems at humanity that are too hard for it - although I can't find a quote at the moment.) I particularly appreciated how Harry only used tools that he had deliberately prepared in advance, sometimes way in advance, e.g. the healer's kit.

I also wonder where Fawkes was while this was happening. You'd think he would've found his way to either Harry or Hermione.

I have a mild complaint about all these cameos. Some of the names of the people who end up getting cameos don't fit in the Harry Potter universe to my ear and they stick out really noticeably. One of the first things I'd do if I were hypothetically rewriting HPMoR for publication is to come up with a consistent and meaningful naming scheme.

I think it's ironic that at the begining of the update, Harry refers to Filch as a "low-level random encounter whom [he] often breezed past wearing his epic-level Deathly Hallow".

I haven't read much Hary Potter fanfiction, but what I have, including HPMoR, tends to up the difficulty considerably, and makes this apparent by having the characters use the same trick that Ron knocked out the canon troll with to little or no effect. (In this case, Eliezer made it clear in Quirrel's first class that that trick would be dreadfully unlikely to work.) Is this a trend in HP fanfiction (in which case, it seems to fall into the class of "taking HP fanfiction tropes and doing them better" that Eliezer's been following)? Or is my sample size too small?
3Qiaochu_Yuan
I think most Harry Potter fanfiction doesn't have a difficulty level as such. Your sample is probably extremely unrepresentative.
[-]loserthree320

I predict that it will be revealed that Quirrell or a closely related entity has been abusing Harry on and off throughout his life, to try and make him into a Dark Lord.

He can go to Harry's house like the time he played Father Christmas.

Obliviated memories leave residue, which is how in Chapter 88 the twins remembered that they could find people, in the castle, but couldn't remember how.

In the first chapter, Harry noticed that he believed in magic.

some part of Harry was utterly convinced that magic was real

In chapter 16, Harry is almost reminded of something when he looks at Quirell, but can't remember what. And when Quirrell is first introduced, Harry ominously recognizes him

"Professor?" Harry said, once they were in the courtyard. He had meant to ask what was going on, but oddly found himself asking an entirely different question instead. "Who was that pale man, by the corner? The man with the twitching eye?"

"Hm?" said Professor McGonagall, sounding a bit surprised; perhaps she hadn't expected that question either. "That was Professor Quirinus Quirrell. He'll be teaching Defence Against the Dark Arts this year at Hogwarts."

Edit: I just realized that Harry was probably abused almost every night (or day) for some significant period. There was a time turner involved, and that's why his sleep cycle is off.

I don't know about this, for a couple of reasons.

1) If there was a time turner involved, why do the issues with Harry's sleep schedule persist even after he gets to Hogwarts and gains a time-turner of his own?

2) If someone spent a two-hour period of time abusing Harry and then time-turnering it away every day, wouldn't he get tired two hours early nstead of two hours late? That is to say, wouldn't his sleep cycle appear to be 22 hours instead of 26?

Reply
6loserthree
For the same reason his response persist even when the abuse no longer does: he's been conditioned. It goes the other way. See, while he was being abused for two hours a day that no one else experienced, he was experiencing 26 hour days when everyone else was experiencing 24 hour days. So his body adjusted to that.
1Skeeve
I'm having a little trouble making the timeline work out on this, since one wouldn't be able to notice his sleep issues while the time-turner abusing was ongoing; it would be a consequence that appeared after the fact. It's mentioned in chapter 2 that Harry was in school when he was seven; that could be argued as evidence that his sleep issues hadn't quite manifested at that point, and that he'd been pulled out of school soon after, once they did. But that still leaves a period of three or four years for Harry to readjust to 24 hour days. You'd think Harry and his parents would have at least tried some kind of therapy, if the issue was severe enough to pull him out of school, and in the absence of some kind of reinforcing factor, why wouldn't said therapy at least have made some progress on the issue?
1aausch
The story clearly states Harry's explicit interest in not attending school, so he wouldn't have tried anything to change his sleep pattern for that purpose, and I doubt by the age of 10 he'd found any other important reasons to motivate sleep pattern changing therapy. I also doubt his parents' preferences matter, here, and even if they did prefer he change his habits, I doubt they'd press him into therapy without his explicit, cooperative, interest.
[-]Qiaochu_Yuan110

My interpretation is that all of these are symptoms of Harry's dark side (which is the backup copy / horcrux of Voldemort somewhere in him).

There was a time turner involved, and that's why his sleep cycle is off.

This is an intriguing hypothesis, but are you aware that Eliezer also has this condition? I was under the impression that he was working off of his own experiences here and nothing more.

[-]elharo120

I think the simpler "conscious Horcrux inside Harry" theories are ruled out by the sorting hat: "I can tell you that there is definitely nothing like a ghost - mind, intelligence, memory, personality, or feelings - in your scar. Otherwise it would be participating in this conversation, being under my brim."

It is possible that the original, canon Harry has been completely replaced by Voldemort, or that the Horcrux has merged with Harry to form a new single personality. The sorting hat is also explicit that it does not remember previous students such as Tom Riddle as individuals. Therefore it would not notice if HJPEV were in fact Tom Riddle redux. However there's just one person in Harry, not two.

The hat talked specifically about objects under its brim. Maybe the horcrux is in some other part of Harry?

I probably heard that at some point; it's been years since this started, now. But I expect better of him than "I get ingrown toenails and ingrown toenails don't get enough attention from the public so I'm going to give my protagonist that problem, too." Also, cannon Harry didn't have the sleep cycle problem. For the most part, there are in-universe reasons for departures from cannon other than, "That was dumb and I'm not writing a story with dumb in it."

This is good evidence right up until you destroy your own case: "Quirrell expected Harry to become a Dark Lord when he spoke with him after the first class and was surprised that Harry aspired to science." Surprise that Harry aspired to science is not what someone who had been regularly communicating with Harry for a decade would experience. On the other hand, you're firing with some fully automatic plot-armor-piercing bullets, there. Quirrell's primary motivation is clearly to groom Harry for some future, so if he waited to start doing so until Harry entered Hogwarts, why did he wait? My favorite theory (Harry is an amnesiac transfer of Voldemort, Quirrelmort is just a horcrux) is only slightly better here. In this case Quirrelmort wouldn't anticipate how much a happy childhood might change Voldemort's personality and wouldn't see the need to remold himself until after that first encounter. That still doesn't explain why he wouldn't even check in on himself for a decade. It took that long for the "mort" part of Quirrelmort to take full control? Or maybe after taking control Quirrelmort knows he only has a year's worth of activity before decaying away, so he chose to save it when he would have extended contact with Harrymort and the latter would be studying magic?
5buybuydandavis
So that Harry would have started to use magic, and could be seen to defeat Voldemort in combat, instead of just be part of some freakish accident that killed Voldemort. Harry "defeats" Voldemort while Voldemort downloads into Harry, transforming himself from Villain to Savior and living happily ever after.

I don't think so. He's not supposed to use magic on Harry, and his attempts to influence him through their link fail as well.
4loserthree
His inability to influence Harry through the link does not reflect an inability to influence him at all. His influencing the everloving fuck out of Harry in Defense Class. The part where he can't use magic on Harry is more of a poked hole in this theory, though. I can answer it, of course, but not without raising more questions. I'll think about that one.
1MugaSofer
Woah. I don't even care if it's wrong, that's brilliant.

It's come up several times before. I believe the usual counterobjection is something like 'that if Harry is being kept up 6 hours later by a Timeturner in order to be abused, then he would fall asleep earlier and have an 18-hour cycle, not the opposite direction'.
2MugaSofer
Ah, but if he adapted, and the abuse stopped, then he would end up with a longer cycle. I think that's the idea, anyway. I seriously doubt that's actually what happened though; not EY's style, somehow.
1gwern
Well, covering up child abuse with a Timeturner seems like Eliezer 'you know what's a good abuse of Obliviation? covering up rape' Yudkowsky's style; it's just the adaptation that is extremely implausible since sleep cycles don't work that way.

Without endorsing any part of this comment dealing with events which have yet to take place, I congratulate user 75th who receives many Bayes points for this:

http://lesswrong.com/lw/bfo/harry_potter_and_the_methods_of_rationality/6aih

Hermione is dead. Hermione Granger is doomed to die horribly. Hermione Granger will very soon die, and die horribly, dramatically, grotesquely, and utterly.

Fare thee well, Hermione Jean Granger. You escaped death once, at a cost of twice and a half your hero's capital. There is nothing remaining. There is no escape. You were saved once, by the will of your hero and the will of your enemy. You were offered a final escape, but like the heroine you are, you refused. Now only death awaits you. No savior hath the savior, least of all you. You will die horribly, and Harry Potter will watch, and Harry Potter will crack open and fall apart and explode, but even he in all his desperation and fury will not be able to save you. You are the cord binding Harry Potter to the Light, and you will be cut, and your blood, spilled by the hand of your enemy, will usher in Hell on Earth, rendered by the hand of your hero.

Goodbye, Hermione. May the peace and goodness you

Or alternately, somewhere in the literally thousands and thousands of predictions or claims (I have ~200 in just my personal collection which is nowhere comprehensive) spread across the 20k MoR reviews on FF.net, the >5k comments on LW, the 3650 subscribers of the MoR subreddit, the TvTropes discussions etc etc, someone got something right.

You know perfectly well that one does not get to preach about a single right prediction. He had the opportunity to make more than that prediction, and he failed to take it.

He also predicted that Hat and Cloak was Quirrell, Santa Claus was Dumbledore, and S. was Snape. He considered these predictions blatantly obvious as well. I remember receiving ~13 upvotes for arguing that Quirrell could be ruled out as H&C, so it wasn't as obvious to all of us.

All of which were consensus beliefs; do not make the mistake of interpreting upvotes as object-level agreement - you may have received the upvotes for making the anti-Quirrel case well or bringing up some bit that people hadn't remembered or just being funny.

It's a large space, not a binary yes-or-no, so successful predictions are impressive even given a large base. Also I could be prejudiced but MoR is supposed to be solvable god damn it.

Someone was criticized. S/he was right, the critics were wrong. The neural net updating algorithm calls for a nudge in the appropriate direction of "Beware of dismissing those who speak with what you think is too much confidence."

No, it doesn't, not out of thousands of predictions of which you selected one post hoc. If I may quote you, our minds do not run on floating point beliefs.

If 75th's predictions were just luck, wouldn't it be likely for there to be other people who got a smaller number of the predictions right?
2gwern
Yes. If you look through the threads or the PredictionBook entries, there are plenty of people blowing predictions. (A particularly good example was the Wizengamot trial: how would Harry rescue Hermione? The actual solution was 1 of the top 2 or 3 suggestions, but that still implies a lot of people favoriting wrong solutions.)

Even if 75ths predictions aren't just luck, you don't have enough information to meaningfully update across such a broad reference class. If it's got to overcome the weight of everyone I think is speaking with too much confidence on the other end of the lever, it's not going to move far enough to be noticeable.
3elharo
I update in favor of "user 75th is more experienced in the tropes of enigma fiction." Indeed I would not be at all surprised were I to discover that user 75th writes such fiction him or herself. It similarly wouldn't surprise me if user 75th had gone to the library and checked out and read some of the same 15 books Elizier checked out and read before writing HPMoR. For example, before reading the author's notes on HPMoR I was not familiar with Chekhov's Gun. Now that I am, I am much more likely to catch such a device when it appears in other fiction. I now suspect user 75th is quite familiar with Chekhov's Gun and other standard tricks of this sort of story. 75th picked up on one such trope (one I'm still not familiar with) that signaled that Hermione was heading for death. If there's a general update to be had here, it may go something like this: Before dismissing those who speak with what I think is too much confidence, I need to consider the possibility that their confidence is based on facts or experience I am not aware of. I should probably take five minutes to ask them why they are so confident before dismissing them.
[-]75th350

Ha, you've got me all wrong. I am woefully under-read, particularly in fiction. I get a very small percentage of the references Eliezer makes in Methods; most of the time, I find out that he's borrowed something months (or, let's face it, years) after I read it, only by seeing someone else explicitly point out the reference. I have had my life ruined by TV Tropes, but most of what I'm familiar with there is video games, and not too awfully many of those.

But it's not a matter of picking up on specific tropes, exactly. It's more a matter of getting into the author's head. Of constantly asking "If this were foreshadowing or a setup or a clue, what would be the most effective payoff?" I read Chapter 84, and then, put together with many other quotes from my many rereads of HPMoR ("Nothing really bad ever happens at Hogwarts", "Her life was officially over", etc.), I answered that question with "Hermione will die horribly," then posted how I felt about it.

Amelia Bones isn't a member of the Order of the Phoenix. One wonders why she would even know about it at all, if she had nothing to do with it.
375th
Well, I think Lucius probably made sure a long time ago that everyone knew what Dumbledore (supposedly) said to him. I didn't get the feeling from that scene in the Wizengamot that Dumbledore-killing-Narcissa was any kind of a secret idea that people were just then finding out about. This does rather change my view of some of the peripheral details, though. Previously, one possibility I pictured was Dumbledore restraining Amelia from her vengeance until Aberforth died, then relenting. I knew Amelia Bones wasn't in the OotP, and I knew she felt distaste at Dumbledore's softness, but somehow I never completely drew the conclusion that she wouldn't care one whit about what Dumbledore said or thought, and therefore probably wouldn't have cared if he had tried to restrain her. Perhaps more likely, then, is the other way I pictured it: that Amelia couldn't get to Narcissa by herself, and after Aberforth's death, Dumbledore actively approached Amelia and said "Okay, I'm ready to help. I'll be the ward-breaker, you do the deed."
5pedanterrific
Whoops, looks like you're right, the accusation was public knowledge:
3ChristianKl
I think you miss that this is a work of fiction that has an author. Think about why the author was motivated to make certain choices instead of thinking why the characters were motivated.
0Alsadius
That is actually the other reason that I believe as I do. It seems like a much more interesting storytelling decision for my theory to be correct than for the competitor theory to be.
275th
How is it more interesting storytelling for the guy everyone thinks did it to have done it, as opposed to "Here's a puzzle and the clues to figure it out"?
0Alsadius
Because it was a puzzle for the first what, 80 chapters? We're getting close to the end of the story as of about two arcs ago, it's time for puzzles to get solved. it's not an interesting enough puzzle to justify a double twist, IMO.
175th
You think it's not an interesting puzzle because you think it's not a puzzle at all. :) And wouldn't it only be a double-twist if Dumbledore did do it? If Amelia Bones did it it would just be a single twist.
2Alsadius
Baseline assumption: Team Death Eater is slandering Dumbledore when they claim he burned Narcissa Malfoy alive. Twist: Nope, Dumbledore actually did it. Double Twist: Or it was some random lady who used the word "burn" once. You know, whatever. One of these twists is revealing of important information about a main character, future motivation for interesting developments(Harry being forced to choose between Draco and Dumbledore over the promise, or Draco having to forgive his mother's murderer), a subversion of our expectations, and is reasonably predictable from evidence dropped in advance. One of them is irrelevant and a complete cop-out of all the character development built into the original twist. Take a guess which one I assume is more likely to be true. Amelia killing Narcissa would be the sort of thing M Night Shyamalan would write.
275th
If that were indeed an accurate summary of the situation, I would agree with you. I did agree with you, when that was the only potential clue I knew of. All three major clues would be circumstantial in real life, but when you step out a level and see that Eliezer writes this story, choosing every word we read, it's clear that he wants us to figure out that Amelia has something more to do with Narcissa's death. It's just as important if Dumbledore didn't do it as it is if he did; it's another piece of evidence that he's not a huge evil hypocrite. Which many HPMoR readers seem to need. I think it'll be pretty interesting when Harry finds out that Amelia did it; Amelia was going for painful revenge, while Harry is already hemming and hawing over whether Dumbledore deserves to be an enemy if he did do it. Harry is much more likely to declare Amelia his enemy, and Amelia is much more likely to declare Harry her enemy. Sounds to me like Amelia would be the biggest subversion of your expectations! Given the several conversations I've had on this topic, I'm pretty sure that Amelia's guilt will be a subversion of most people's expectations. In fact, I and possibly pedanterrific may be the only ones in the entire readership whose expectations aren't subverted. I really don't understand why everyone thinks the three clues I identified are worth so much less than the clue-and-a-half we have about Dumbledore. And this is why I didn't actually mean to start this conversation again; this is the second or possibly third time that I've pushed someone to declare Eliezer a bad writer if my hypothesis proves true, who will now actually feel that way when it is proven true, where they probably would have just said "Huh!" before, or maybe even thought it was cool. I just don't get it. I don't understand people's reluctance to believe this, to step outside the text and realize that these are purposely written clues. Maybe it's because I'm acting all certain again; maybe perceived ov
5Desrtopa
As someone who takes clues in the form of literary convention, extrapolation of authorial intent, etc. on a regular basis, I just think you're really reaching.
7gjm
As a general principle, it seems to me that most of us, most of the time, are really bad at recognizing the extent to which other people, even ones who are reasonably honest, sane and intelligent, can reach different conclusions from our own. This is a large part of why political and religious discussions get so overheated. What's not so clear to me is how far this is because so many people are so bad at thinking, and how far it's because the available evidence often really is that ambiguous. Naively it seems as if, for most questions that are in principle resolvable empirically, the totality of the available evidence should end up pointing very clearly one way or another, so persistent divergences must indicate either failures in thinking methods or something like confirmation bias where different people effectively see very different subsets of the evidence. (Both, alas, very plausible.) But given that even very intelligent people trying hard to be rational, with a reasonable knowledge of cognitive biases can end up holding quite different opinions, perhaps there's more real ambiguity than one would naively think. Or perhaps it's just that no human being is really "very intelligent"; the most we ever achieve is "very intelligent relative to the appalling baseline of human stupidity, and still really pretty stupid". ... But I digress; in the present case it seems fairly clear that there just isn't more than, say, 10:1 evidence for Dumbledore over Bones or vice versa. [EDITED some hours after posting, to fix a minor ambiguity I hadn't noticed.]
575th
Maybe not 10:1, no. But one thing that does seem to have been lacking in all the dissents from my theory is any textual clues pointing to anyone else. Sometimes the people who object have harebrained ideas, like the person on Reddit who said that Regulus Black was a more likely suspect than Amelia Bones. Sometimes, they're committed that Dumbledore did it. But so far as I can tell — and please, please, please tell me if I'm missing anything — the only evidence for Dumbledore's guilt is 1. Lucius says that Dumbledore told him he did it. 2. Narcissa's death represented a strategic victory for the side of the war Dumbledore led. 3. Narcissa's death was subsequent to Aberforth's death. To me, that is what Eliezer does — information he explicitly gives us and points to and puts blinking lights around — to set the default starting point for the mystery. That is the baseline, boring, standard theory. The Amelia clues I keep bringing up, though, are different. I may do this completely wrong, but it is written: You can see Amelia make a "burn" reference, or say that she hates Bellatrix for killing her brother, or speak up in the Wizengamot, and say "That is some really, really circumstantial evidence." And in-universe, in the story, that's absolutely true. You could never justly convict someone in the real world on that evidence alone. But Eliezer wrote those lines. The same brain that created the Narcissa mystery in the first place also made these explicit decisions: "Amelia Bones thinks of burning for revenge. Amelia Bones's brother was killed by Narcissa's sister. Amelia Bones will be the one to speak up at Dumbledore about Narcissa's death." It seems to me that the Eliezer who believes that Amelia killed Narcissa is way more likely to make those three not-binary decisions that way than the Eliezer who believes that Dumbledore or someone else did it. Pfah. I'm no good at this. Eliezer, if you're reading this and I'm right, I'd like to cash in those Bayes Points
2Alsadius
And yet, textual analysis of the same sort is exactly what led me to the Dumbledore theory. I wrote off Draco's comment as propaganda, and then Dumbledore's "They learned not to mess with our families" line clued me in that he did it. The line is too on-point for anything else - certainly more so than any of the Bones evidence. His motive is better, his textual clues are clearer, and he explicitly said that he did it. Doesn't a confession count for anything any more? I agree with your analytical methods. I just think you're misapplying them egregiously.
275th
Saying "They learned not to mess with our families" with a stone cold look on his face is what you'd expect Dumbledore to do whether or not he killed Narcissa. The statement is a simple fact. The memory of Aberforth's death and mere knowledge of Narcissa's seems to me plenty sufficient to produce that line and that look. Harry has even explicitly thought that Dumbledore has acted consistent with either possibility. I grant that that thought was more about the "Only a fool would say 'Yea' or 'Nay' " line, but if Harry thinks the line you mentioned is evidence of guilt, he has failed to think it where we can hear him, even when he was thinking through this entire issue. Maybe, and yet the deed is still out of character for him, where it's not nearly as much for Amelia, and Amelia's motive is plenty good, given that Bellatrix was too powerful to attack directly. Such as they are, they're more explicit and blatant and obvious, yes. That just means it's a crappy mystery if you're right. I know I always say "Not everything that is mysterious to the characters is supposed to be mysterious to us", but that's more about things where we're supposed to use our enhanced knowledge of canon or alternate POVs, where it takes deliberate suspension of learning or blatant failures of reading comprehension to keep from admitting the truth. Not like this issue, that's obviously supposed to be a mystery that will be revealed later. Says Lucius. Maybe Dumbledore said he did it, or maybe he used weasel words to lead Lucius to that belief without lying, or maybe he admitted some involvement without saying he cast the spell that killed her. The fact is, Dumbledore had a vested interest in the bad guys’ believing that he did it; therefore, any alleged confessions made by Dumbledore to the bad guys should be treated with suspicion. EDIT: As a gesture of goodwill, let me post the best evidence I've seen that Dumbledore might have killed Narcissa, that I just now thought of and haven't seen
2Sheaman3773
An interesting thought, and one that I had not considered in this light. And yet, right afterwards: This seems to make it clear to me that it is not that Dumbledore thought that he would never kill, and then Voldemort's war changed that, and he killed. It's that he thought that he should never kill, and then Voldemort himself became the exception, changed the rules so that he should kill Voldemort. At least, it is an alternate possibility.
0linkhyrule5
There is, of course, the Third Option. Dumbledore did it, but he did not do it personally. If Dumbledore manipulated Bones into murdering Narcissa, then we would have a universe where both Dumbledore and Bones would be emotionally affected by her death, where Bones would not want Dumbledore to take the legal blame and where Dumbledore would willingly take the (informal) blame.
275th
I don't think Amelia Bones is the kind of woman who needs to be manipulated by Dumbledore to get revenge. My similar hypothesis is that Amelia needed Dumbledore's help to infiltrate Malfoy Manor and pull it off. Aberforth's death provided the impetus for Dumbledore to help, but he didn't cast the spell.
0linkhyrule5
Aumann's Agreement Theorem. None of us are rational or observant enough to qualify, unfortunately.
3gjm
The Agreement Theorem is a consider-a-spherical-cow sort of result; its preconditions are absurdly strong. (In particular, the fact that the agents concerned are required not only to be perfect Bayesian reasoners but to have common knowledge that they are so.) But even without Aumann one might hope for better agreement than we actually see...
4wedrifid
Eliezer's overconfidence script is dangerous.
2Sheaman3773
Observation bias. Just because the two people mentioned speak up about it (presumably) so much more than others doesn't mean that they are the only ones who hold this belief. I share this belief with you, for instance. I find those hints to be convincing, narratively speaking.
075th
Which is why I think it a significant possibility that Dumbledore helped in some way. Any of those defenses might be sufficient for a single clue, but you have to take the clues together. Three successive clues (plus her character) pointing to Amelia, and only some words spoken to Lucius that we never saw pointing to Albus (and everything else we know of his character pointing away from him, though I know some would argue that), increase the probability of Amelia's guilt quite a bit more than linearly.

A correct prediction is meaningless because it wasn't accompanied by another correct prediction?

More or less. Think of it in terms of selection bias: a bunch of people enter a lottery of some sort. After the lottery concludes, the lottery organizer Yliezer Eudkowsky praises the winner, entrant #57, for their deep insights into lotteries and how to guess the winning number and admonishes everyone who told #57 to not get his hopes up. Do we now credit #57 for wisdom and study his numerology? No, not really.

Now, if #57 had simultaneously entered 5 other lotteries and won 3 of them, then we would start wondering what #57's edge is and preorder #57's upcoming book Secrets of the RNG Illuminati. Or even if he had won none of those other lotteries and simply gotten 3 near-misses (5 out of 6 digits right, for example), that would still serve as replication of above-average predictive accuracy and not mere selection effects, and persuade us that something was going on there beyond randomness+post-hoc-selection.

Mm. I think there's wisdom in the approach of only making public predictions when you're very confident in them, and that may have been the only thing 75th was that confident in. (This isn't a very good approach for calibrating your brain's sense of uncertainty, but it has other benefits.)

I am breaking my "only comment on LW if you expect some benefit" rule because I am in a somewhat unique position to comment on this, and I agree with Eliezer that "penalizing people for sounding certain or uppity or above-the-status-you-assign-them can potentially lead you to ignore people who are actually competent". See, I made this update at an earlier time under not-dissimilar circumstances. (In short, I thought ArisKatsaris was making an overconfident prediction about HPMoR, bet against him, and lost.)

An excerpt from my journal, 3/28/2012:

Well, I lost my bet. But what did I learn? Give less probability mass to “some unknown possibility no one has thought of” when the number of people thinking is sufficiently large. Also, arrogant people may be arrogant because they’re usually right, so be careful of the impulse to smack them down.

Well, in the spirit of sticking your neck out: Harry was sorted into Slytherin. Dumbledore created Harry to be the ideal literary hero. Lord Voldemort doesn't want to conquer the world. Dumbledore is working on way more advance information than everyone else.
[-]Pavitra150

Counter-evidence: Harry produces blue and bronze sparks at Ollivander's.

As long as we're sticking necks out, though:

  • Definitely: The horcrux technology uses the ghost phenomenon. Specifically, by causing the violent death of a wizard under controlled conditions (i.e., murder) it's possible to harness the powerful burst of magic to make a ghost of the living caster instead of of the dying victim: a backup copy. A ghost may be static data rather than a running instance, but hey, so is a cryo patient.

  • Definitely: Baby Harry was overwritten with a horcrux-backup-copy of Voldemort. Voldemort didn't plan on childhood amnesia, though, and much of the information was erased (or at least made harder to access consciously). The Remembrall-like-the-Sun indicated the forgotten lifetime as Riddle. Remnants of Voldemort's memories are the reason Harrymort has a cold side; his upbringing in a loving family is the reason he has a warm side.

  • Mere hunch: In chapter 45, the Dementor recognized Harry as Voldemort and addressed him by name: "Riddle".

  • Mere hunch: Voldemort may have chosen to impress his horcrux in a living human in order to try to get around the "static data" pro

Some of the horcruxes in canon are made from murdering Muggles, though. I don't see anywhere that this happens in Chapter 45.
9monsterzero
Very early in the chapter: "He had regained an impossible memory, for all that the Dementor had made him desecrate it. A strange word kept echoing in his mind." And later: "Harry glanced in the Dementor's direction. The word echoed in his mind again. All right, Harry thought to himself, if the Dementor is a riddle, what is the answer? And just like that, it was obvious." Once Harry figures out what Dementors are, he stops being able to hear their "voices", because he no longer sees (hears) them as sentient. But if "the word" was actually coming from the Dementor, I don't know what would've kept everyone else from hearing it.

Both of her legs were eaten by a troll before she died, and as she died, she whispered to Harry, "Not your fault." Check.

You will die horribly, and Harry Potter will watch, and Harry Potter will crack open and fall apart and explode, but even he in all his desperation and fury will not be able to save you.

Check.

Interesting that Harry uses his med pack he bought in anticipation of almost exactly the scenario which played out when he used it, except that Hermione absolves him instead of cursing him.

“One of my classmates gets bitten by a horrible monster, and as I scrabble frantically in my mokeskin pouch for something that could help her, she looks at me sadly and with her last breath says, ‘Why weren’t you prepared?’ And then she dies, and I know as her eyes close that she won’t ever forgive me—”

The detailed foreshadowing often seems like part of the story, not just as aspect of the story. What is said comes true much more than it should, and in much more detail than it should. "Bitten" is a very specific way to die.

You know, speaking of foreshadowing...

That very quote led into McGonagall's theory that Harry had suffered some kind of trauma and had it Obliviated. And then there was that business with the Remembrall in chapter 17. I'd have to go back and check for more instances of Harry specifically foreshadowing a future event like this, but more and more I'm beginning to think that Harry has forgotten or locked foreknowledge that's leaking into his subconscious.

[-]buybuydandavis160

But in Chapter 17, McGongall rejects the theory that remembralls detect Obliviation.

“More importantly, why did the Remembrall go off like that?” Harry said. “Does it mean I’ve been Obliviated?”

“That puzzles me as well,” Professor McGonagall said slowly. “If it were that simple, I would think that the courts would use Remembralls, and they do not. I shall look into it, Mr. Potter.” She sighed. “You can go now.”

But, strange that Harry doesn't think to keep experimenting with the Remembrall.

Harry had forgotten that he was not to use his timeturner in front of other people- a fact which got him a very stern rebuke from Mcgonagall.

That's plausible, but if so, it seems like a very disproportionate response from the Remembrall; that is assuming that under ordinary circumstances Remembralls light up like they do in canon, which I suppose is not necessarily a given.

It's not going to happen. You don't hang that much drama on an event if you intend to reverse it quickly, unless you're going for comedy, and comedy doesn't make sense in this context.

That said, if you'd asked me a day ago I would have said that there are too many dangling plot threads surrounding her for the story to do what it just did, so it's probably a good idea to adjust your confidence of predictions based on narrative mechanics appropriately.

It sounds like you might be mistaking Eliezer's role in this, and mistaking your desires for desires we can reasonably assign to Eliezer.

This isn't something that happened to the HP&tMoR version of Hermione Granger, this is something that Eliezer, the author did to the HP&tMoR version of Hermione Granger.

He did it for a reason. He's almost certainly been planning it all along. If it made him sad then it first made him sad quite some time ago. He's not feeling the surprised dismay you have today.

He wanted this.

Time turners cannot alter anything the user knows about (for some value of `know'), so it would require reenacting this exact scene. So someone would have to simulate Harry's experiences, including the magical event, confuse Harry's patronus as to location of Hermione (or cause Hermione to actually be on scene, albeit invisible), and control the troll, so that it behaved exactly in the way Harry remembers it to have behaved. Also, Dumbledore would need not to tell Harry anything that he couldn't have lied when he said he was responding to the death of a student.
6elharo
I'm betting Hermione is really, really dead (though Harry may yet resurrect her). However, remember that writing a story is often the inverse of reading it. It's like solving a maze by starting from the goal and working backward to the beginning: often much easier. If (big if) Hermione is resurrected and/or not really dead, then Eliezer very likely started from a narrative goal of having Harry see Hermione's horrible but fake/reversible death and then worked backwards from there to make it happen. As readers we have the much tougher task of working forward from the clues to the correct conclusion. That is, Eliezer did not have to figure out how to write himself out of this series of events. He constructed these events to lead to the conclusion he wants.
2Alsadius
The soul releasing seems easy enough to fake, as does Hermione's comment to the Patronus. Hermione being under an invisibiliy cloak near fake-Hermione would do for the Patronus taking Harry to her(though screaming mid-combat would be quite dangerous, even invisible). The hardest part would be creating a fake Hermione sufficiently well to convince both the troll and Harry. Do we know of any magic sufficient to that task? Copying the form can be done, as was done with the Azkaban breakout, but the blood and the talking both seem outside the capabilities of that spell.
4Pavitra
It's not obvious to me how to fake the soul releasing. It was perceived by the magic-sense, not just with the muggle senses.
4NancyLebovitz
Here's a miserable plot possibility. Hermione was concealed, something went wrong, and the feeling of her mind going past was because a number of other things happened, and the concealed Hermione was killed. Neutral plot possibility: usually, dying minds aren't felt in the wizarding world. Something unusual was going on, and I don't know what it was.
2JoshuaZ
This seems unlikely. This would end up sounding a lot like "don't tamper with fate". That sort of thing is very common in time travel stories where someone tries to save someone's life, but it has a massively anti-transhumanist, pro-deathist vibe. I doubt Eliezer would do it.

I'm assuming that Hermione is going to be brought back somehow, so the implication isn't that you can't fight fate, it's that the world has wildly complicated plot twists.

This seems unlikely. There was a mention about ghosts being caused by "the burst of magic that accompanied the violent death of a wizard" (or something along those lines -- I don't feel like looking up the exact quote right now.)

Thank you for saying this. I've been hoping someone would make note of this. Don't people remember the fight with the bullies in ch 73? If the mad burst of intellect and magic and etc. was standard, they wouldn't have been able to fake it for even a second. Now, I'm not necessarily saying that the feeling was only because of something fishy going on. I'm just saying that it cannot be the standard.
0aleksiL
Hmm. How about having someone else die in Hermione's place? I don't recall offhand if the death burst was recognizable as Hermione, but otherwise it seems doable. Dumbledore said he felt a student die and only realized it was Hermione once he saw her. You'd need polyjuice for the visual appearance, and either Hermione's presence or a fake Patronus for past-Harry to follow. Hermione is unlikely to go along with the plan willingly sho she'd need to be tricked or incapacitated. Hard to tell which would be easier. Given the last words, Hermione's doppelganger might need to be complicit with the plan. Easy to accomplish if it was Harry, but I think he's too utilitarian for that. He'd need someone loyal but expendable. Lesath would seem to fit the bill, but I wonder if he'd agree to literally die on Harry's command.
1robryk
Either Dumbledore is on it and lied to Harry, or it was a student. Harry seemed to think so, but he was obviously biased by seeing Hermione. Doesn't it wear off after death? Ch92 spoiler: Ur'f nyvir ng qvaare naq ur unf ab gvzr-gheare (Uneel pna'g gnxr bgure crbcyr nybat), fb vg qbrfa'g frrz vg unq unccrarq. Overall, this plan requires at least 2 hard things to happen correctly: identical fake magic burst and getting real Hermione there and screaming or Patronus shenanigans. I disbelieve this strongly.

That's true, it's still possible. Nonetheless, there is still a scene where Harry watches Hermione die and can do nothing about it. So I'd consider that it checked even if he brings her back / somehow prevents it retroactively.

From Chapter 6:

Harry was examining the wizarding equivalent of a first-aid kit, the Emergency Healing Pack Plus. There were two self-tightening tourniquets. A Stabilisation Potion, which would slow blood loss and prevent shock. A syringe of what looked like liquid fire, which was supposed to drastically slow circulation in a treated area while maintaining oxygenation of the blood for up to three minutes, if you needed to prevent a poison from spreading through the body. White cloth that could be wrapped over a part of the body to temporarily numb pain. Plus any number of other items that Harry totally failed to comprehend, like the "Dementor Exposure Treatment", which looked and smelled like ordinary chocolate. Or the "Bafflesnaffle Counter", which looked like a small quivering egg and carried a placard showing how to jam it up someone's nostril.

From Chapter 89:

"Fuego!" / "Incendio!" Harry heard, but he wasn't looking, he was reaching for the syringe of glowing orange liquid that was the oxygenating potion, pushing it into Hermione's neck at what Harry hoped was the carotid artery, to keep her brain alive even if her lungs or heart sto

I think I've identified three techniques Eliezer uses to create associations in the readers' minds and promote ideas to their attention.

There's repetition. If you're sensitive to repetition then the repetition will drive you mad. Five false prophets, many uses of Grindelwald's name, and about a zillion instances of the phrase 'the old wizard'. Dumbledore is old, old, old.

There's placing two related ideas side by side. Like Harry wondering how magic could possibly work, then segueing into an 'analogy' to artificial intelligence. (Repeatedly, so it's a twofer.) Or the description of phoenix travel appearing in the same chapter as Harry confronting Dumbledore over Narcissa's death.

And there's the throwaway gag that contains the literal truth. "It's not like I'm an imperfect copy of someone else." "Let me know after it turns out that it was Professor Quirrell who did it."

And, perhaps, "And if you coincidentally crack the secret of immortality along the way, we'll just call it a bonus."

What happened to Hermione was shocking and has nearly monopolized the posts in this thread so far.

There's aftermath coming, though, and I'd like to talk about that. Harry is probably in a lot of trouble. Here's a short list of rules violations:

  • He left the Great Hall when specifically warned that doing so would result in expulsion and when he's not allowed to be expelled.
  • He inspired other students to take up arms against their teachers, or their groundskeeper, or against their teachers by way of their teachers' groundskeeper, or something. It probably got even worse after he left.
  • He endangered other students, the twins, even before confronting the troll by way of unsafe broom usage. Point three see, and all that.
  • He revealed his super-secret patronus that Dumbledore told him to keep secret, a super secret.
  • He may have damaged His Father's Rock.
  • He transfigured something that burns, specifically so that it would do so.
  • He has committed himself to a course of action fundamentally at odds with participating in society in any reasonable fashion.

The transfiguration is probably the worst on the list, really. If Harry is lucid at the end of this chapter I expect there will be so... (read more)

I actually expected Harry to cast the Killing Curse as a last ditch desperation/rage effort. He knew what it does, has seen the wand movements and pronounciation (in the Dementor dream), knew and had the required state of mind. That should be enough to cast it, as per Ch26 ("He is in his sixth year at Hogwarts and he cast a high-level Dark curse without knowing what it did.").

That's... interesting. Incidentally, I'm not sure how broken elementary charms are in combat other than Transfiguration, and being particularly deadly with Transfiguration without killing yourself requires... not neccesarily Quirrel levels of mana, but some pretty fast transfiguration. It was always my perception that 1. In Azkaban, Harry had almost cast AK on Bellatrix and Quirrel and 2. Before Mad-eye explained that AK is homing and penetrates walls, that it had to be a fairly easy curse compared to, say, Fiendfire or a Cutting Charm or the Mass Accelerating Charm.
1Sheaman3773
1) ...huh. I didn't get that impression. I mean, I certainly got the impression that Harry was going to kill them (starting with the auror) but he doesn't know AK, and one thing Harry has never had trouble with was coming up with clever ways of killing. 2) Um. Homing? I guess I can see where you got that impression, but that wasn't my interpretation at all. I thought it just meant that it will continue going on until it hits a soul, off in a straight line (though obviously I was curious about whether it will curve with the Earth, could you drill into the ground and give a pathway up for magma, etc.).
0ikrase
Hmmmm... Let me describe my perceptions of Rationalverse spells... Avada Kedavra: Moderate to fast bolt, at least a little bit homing or auto-targeting (Allegedly the Sumerian Simple Strike 'has a tendency to hit whatever you look at', this might be similar) at souls, penetrates all normal shields, penetrates at least a few inches of mundane material but probably cannot be targeted in a hugely indirect manner, or would be overpowered. If it homed really well, or was both auto-targetting and an instantaneous bolt, nobody would be able to dodge it. Also, I think that AK does not normally do material damage? The big question is: Why use AK rather than any other curse? Even a moderately powerful wizard should be quite lethal, let alone one educated by Dark Lord Verres. Voldemort is creative enough... Reasons I can think of that are actually stated are only that it penetrates shields and walls. If that were the only advantage, there would be no point in it. Incidentally, a certain irrational part of me will not be truly satisfied unless we see the Battle of Hogwarts, HPMOR style. Although it would hard to keep that to a visually exciting level, rather than HPJEV just burning everything...
0Sheaman3773
Moderate to fast bolt seems reasonable. I don't really see it as homing so much as it tends to fly in the direction that you wish it to, without the ability to adjust its flightpath. It seems that it penetrates all shields, period. Also all materials, period. I mean, I don't get how you can see And think that it would only penetrate a few inches. I'm not saying that Moody is necessarily being completely truthful (though the silence of everyone else in the room is evidence to either truth or preestablished falsehoods) but from what he said, it looks like throwing up a rock or placing a suit of armor between you and the bolt wouldn't actually work. Those kinds of blocks worked in canon, and it did damage the objects. It just doesn't hurt what it hits when said object has a soul. Hugely indirect? Do you mean the bolt curving around to target the victim? Or do you mean shooting it from quite a ways away? It's a one-hit kill spell--if your opponent mostly dodges a Cutting Curse, only brushing them a bit, then they'd come away with a small cut. If they mostly dodge an AK, they're still dead. Also being able to ignore any sort of shield or cover--esp in the Rationverse with their much more complex and comprehensive shields--is incredibly helpful. Or at the very least, this is how I see it.
0ikrase
Only a few inches: There is a huge difference between typical house walls and all the walls in the path of several buildings. There is also a difference between that and a large chord of the Earth. (By comparison, modern heavy machine guns may penetrate a whole city block provided they don't hit anything really heavy, man-portable small arms may penetrate several weaker house walls, or some masonry.) Hugely Indirect: If you can shoot Avada Kedavra through a significant chord of the Earth, then it seems like it would be broken. Targetting might be a problem, but for all the uncreativity of Rationalverse wizards, they are not that bad. Power: Of course, we've only seen two lethal fights in the Rationalverse. (Team Weasley against the troll, and Quirrel against an Azkaban Auror). Team Weasley seems to use spells that seem like they would be instantly disabling if not fatal against a human, especially with more mana behind them. However, shields might change that significantly (How do shields interact with material forces? We've only ever seen this once. Most people use shields to protect against personal effect spells!) What about counterspells? (Unclear how this works, seems to care about stamina or mana, but we've never had a good description of them even though high-powered fighters use them a LOT, and Quirrel relies on them exclusively. Quirrel took a while to fight the Auror, but was going for shock, and not fighting anywhere near full strength. Plus he probably had to attack shields to avoid killing the Auror. What about Hypothetical Auror-Level HPEJV? If Harry can transfigure at a rate of 250 grams per second, he will be able to spam Muggle-style kinetic, directed energy, and explosive weapons, especially if he can use physical or magical air protection and armor. These also would benefit from having no audible incantation and a faster time to first impact. (Nothing like Lily Potter shredding Voldemort with a hail of Transfigured recoil-less rounds!) Granted,

I see. I didn't see it as "it will go through a wall," I saw it as "once it is fired, it will go through anything, and keep on going through it until it hits a soul." Which even on reflection appears to be the more correct interpretation, but that is just my view. ...you don't think that they are that bad, that they could not figure out how to hit a moving target, with a projectile a few inches across, moving slow enough that it can be dodged within a few meters, without the ability to adjust the projectile midflight, through a significant chord of the Earth, when their highest math is apparently trigonometry (ch6)? From the tidbits we've heard about dueling and fighting, yes, shields change that considerably. Could you go into detail about how he could spam these things? I'm quite interested in the concept :)

I guess not a significant chord of the earth, but AK-sniping through huge amounts of intervening material still seems like something that would happen. Spammable Transfigured Muggle Weaponry: This could work a LOT of ways. All of these involve breaking McGonagall's Rules of Transfiguration, but could be made safe for the weapon-user and bystanders using various tricks such as transfiguring (maybe partial transfiguration) them out of very small objects, transfiguring them out of water or other nontoxic substances, or using magical or mundane air protection. Many of these might merit some way to easily provide transfiguration feedstock to one's wand. HPEJV might wrap a strip of duct tape around the end of his wand and transfigure tiny parts of it at a time. * It may be possible to transfigure matter in motion or radiation in flight (Fuzzy line!). If so, then hypothetical Harry with a rate of 1 kg/s can generate over 50 petawatts in beam power. (This would probably be fatal.). * Even if not, than Harry might Transfigure very small beam generation units, primed to fire, and let them fall away (or Finite them) as soon as they have fired. For example, one might transfigure a unit consisting of a super-radioactive (half-life in milliseconds) isotope and beam collimation assembly, or a laser rod in the process of firing from pre-charged capacitors. These devices would do their work as they either fall away or are suspended by telekinesis or some kind of frame. * Alternatively, one could simply transfigure Muggle weapons. McGonagall claims that Muggle guns are not too effective against a good wizard, but she probably is talking about normal small arms. Gyrojet (rocket) weapons or ones that work on the recoil-less rifle principle generate no recoil. Harry could transfigure a stripped-down multi-rocket-launcher or heavy Gyrojet machine pistol right into his hand, fire the entire magazine in less than a second, drop it, and transfigure another.

Or has Dumbledore found it so useful to carry a large rock around that "get a big rock, keep it with you at all times" is in the top five things he'd tell his younger self if he ever got the chance? Seriously -- the fuck?

The obvious interpretation of this is that spellcasting is a skill like any other, and practice develops it. By giving Harry an implausibly large object to carry, and then having him interact with the Transfiguration professor, Dumbledore can be fairly confident that Harry will try to transfigure the rock into something more reasonable to have in constant physical contact with him. This constant transfiguration practice will help Harry level up his abilities, and a huge rock is predictably useful in combat situations.

Here's a short list of rules violations:

He also showed off his unique partial transfiguration trick during combat, which Dumbledore was hoping he would save for the Final Battle.

Only if they autopsy the troll and figure out it was transfiguration and not something else. But I'm pretty sure Quirrellmort already knows Harry can do that.
[-]skeptical_lurker130

He threw the troll's head over the wall, so its well away from anyone who could breathe in the gases, and a simple bubble-head charm should solve the problem. Given that the alternative was being eaten, he won't be punished for it (also, the most important thing is keeping partial transfiguration secret - other students would be told that Dumbledore killed the troll).

The twins were going to try to rescue Hermione anyway.

The twins will probably agree to keep the patronus secret.

While Harry and the twins did break a rule which was said to result in expulsion, they did almost save Hermione, which is more that the staff did. Expelling them would lose even more face then failing to follow through on a threat of expulsion would. Maybe McGonnigal will admit that when it comes to military matters, her students know more then she does. Maybe in future emergencies the 7th year generals will be able to countermand the orders of professors.

Trolls already use continuous transformation on themselves; to find a needle in a haystack with a magnent, you first have to suspect there is a needle. Harry's partial transfiguration attempt(did that happen or...?) is probably more like a needle in a haystack of troll-magic. The only people who I think could spot it without knowing what they're looking for...already know about partial transfiguration. Edit: and then Dumbledore finite's the acid to prevent transfig. sickness. any chance of anyone else figuring it out by looking at the magic involved will be looking for a needle without a magnent.

I can't imagine that Harry, after having been through this event, gives even one iota of a shit about any of those things.

That's easy to say if you're not in the heat of battle. Declaring war on the fabric of reality has a lot more to it than simply ignoring its footsoldiers, and doing so is a bad strategy.

I wouldn't worry about transfiguration sickness: breathing sulphuric acid is probably worse than breathing atomized(?) troll brain matter, and AFAIK sulphuric acid and its salts are either directly harmful or aren't absorbed anywhere interesting in a human.

I doubt that it matters. Sulphuric acid is an oxidizing acid that can do damage through either pH or oxidization while HCl can only ph. Also I think that sulphuric is a more typical acid to ancient alchemists. Furthermore, H2SO4 is a nonvolatile liquid and Harry only produced a small amount of it. Of course if you are Badass Adult Harry, you just transfigure a spot of Chlorine Trifluoride in the troll and watch it explode.

1. The mana cost for incendio is probably much higher than a thin sheet of transfig. 2. I think that incendio simply forms a blowtorch or igntes the outside of objects. Weaponized partial transfig will ALWAYS be more powerful than first-year spells at a first-year mana supply. Partial transfig can slice things up, which is what Harry needed to do.
0sentientplatypus
I was thinking it would work as effectively because of the fire weakness thing and Harry shouldn't be magically depleted yet. Also it would be a lot safer than transfiguring sulfuric acid. Although it's possible the troll was enchanted to make it fire resistant and that Harry frankly didn't care whether he was violating the rules of transfiguration, and merely was worried about speed, but I'm inclined to think incendio would be faster.
2robryk
Or maybe it's not a good idea to cast incendio while the tip of your wand is in a very enclosed location (for instance due to gases that you expect to be released). Or it's maybe that that the transfiguration requires no wand movements (reference: look at the setup used during the partial transfiguration experiment) as opposed to incendio. It's pretty hard to move your wand in some pattern when it's stuck through a troll's eye socket.

It's not a fire vulnerability. It's just that chemical change stops the regen. Just because burning cut troll flesh makes it not regen doesn't mean that it will penetrate. They're not highly flammable like Twilight/Luminosity vampires. If I was designing Muggle anti-troll weaponry, I'd be going for something to penetrate into the body and then spread incendiary material. Not a flamethrower. (Although first physically injuring trolls and then dousing them with napalm might work, sort of. Incendio in the troll's eye would just burn out the eye. Mana cost in HPMOR seems to affect cooldown more than castability of spells, and transfiguration seems to have no cooldown but (for Harry, Q and other powerful wizards are much faster) is time-consuming. Harry should be able to near-instantaneously slice-and-dice any transfigurable object by using very thin cutting boundaries, and even cause explosive separation by using compressed inert gas, or even a friction-sensitive explosive (most explosives form fairly nonhazardous materials) Even if the acid failed to prevent the regen, he could have dismembered the troll temporarily and bought time to try something else or to burn it. ETA: Also, Harry is now able to predict what forms of transfiguration are dangerous, and mild transfiguration sickness is not

The Headmaster can feel when a student dies in Hogwarts. That's how he showed up the moment Hermione died.

But the Headmaster can also feel when a creature unknown to Hogwarts is in Hogwarts. That's how he showed up when Harry rejected his phoenix.

But so why didn't Dumbledore feel the troll and intercept it much sooner? I expect before long the Dumbledore-haters — both those in the story and those on Less Wrong and Reddit — will latch on to this as proof that Dumbledore has been evil all along.

The problem is, we know a thing or two about Hogwarts's wards by now. We know, for instance, that Salazar Slytherin was the one who wove them:

or by some entity which Salazar Slytherin keyed into his wards at a higher level than the Headmaster himself.

Salazar Slytherin's wards. Salazar Slytherin, who left a basilisk that knew all his secrets. Secrets that Quirrellmort now knows.

Dumbledore will try to tell the wizarding world that the only explanation of Hermione's death is that Voldemort was behind the attack. This will be seen by the world as the same thing Headmaster Dippet actually did when Myrtle died: the accusation of an unlikely — "preposterous!" — scapegoat.

And now, Lucius... (read more)

Lucius is going to be outraged and lead an opposition to Dumbledore because the attempted murderer of his son, who he tried to send to Azkaban for 10 years, got killed in Hogwarts? I think that would seem a bit odd to everyone involved.

Lucius has means of his own, and had every reason to arrange Hermione's death.

No, Lucius is going to stir up an opposition to Dumbledore because Dumbledore is his hated enemy. Do you honestly think that Lucius would pass by any excuse to harm Dumbledore? (And he will have a easy time at it too. A troll loose in Hogwarts, killing a student? That will reflect extremely badly on Dumbledore, even from the viewpoint of the neutral factions.)
1buybuydandavis
He'd pass on excuses that don't benefit him. He's the obvious suspect. Accomplishing the crime redounds to his reputation and benefit. Why spoil it? The alternative you propose would seem rather absurd in the face of everyone assuming Lucius arranged the death of Hermione in the first place, after failing to arrange her death in Azkaban.
2ygert
You want everybody to think Lucius is behind it. They have no reason to want to think that. I think this is warping your thinking. From a basic political point of view, I find it unlikely that any but Dumbledore's allies would be trying to pin the blame on Malfoy. Here, tell you what. Predictions should be recorded. Here is my prediction on PredictionBook.
6Intrism
The Headmaster was off campus; it's not necessarily true that he can access all the Hogwarts wards from off campus. He did notice when Hermione died, but considering the giant soulsplosion it's likely that this was somewhat more obvious to him than a wards violation. Furthermore, considering the timing of his absences, it's likely that Dumbledore was off hunting Horcruxes - an excellent opportunity, therefore, for Quirrell to lure Dumbledore into a trap to induce magical radio silence. Politically speaking, it makes no sense for Dumbledore to kill Hermione. Even the Daily Prophet would have a hard time spinning that particular story. The Wizengamot's response to the death of Draco Malfoy's supposed assassin and Lucius Malfoy's hated enemy will not, no matter the circumstances, be to flock to Lucius' side. It would, however, still reflect very badly on Dumbledore; obviously, mountain trolls should not show up in schools, and the responsibility for preventing such things lies with him.
875th
I think you're being generous to the wizarding public. Lucius Malfoy can probably prove — the Hogwarts wards can possibly prove — that neither Lucius nor Draco has been in Hogwarts for quite some time. It won't be too hard for Lucius to say the better-written equivalent of "Regardless of my personal feelings for Miss Granger, I would never besmirch House Malfoy by reneging in such brutal fashion on a matter of House honor. The question at hand is this: how could Dumbledore not have known the troll was in Hogwarts? And if he did know, where was he during the attack? If you would like to propose that Dumbledore and I were in collusion on the matter — well, I'm sure a simple show of hands will make clear how likely this assembly is to believe that." Not too hard for Lucius to talk his way out of. Very much harder for Dumbledore. EDIT: I agree that not all of Hogwarts's wards are necessarily available to Dumbledore off-campus. But the mechanisms of these two wards have been described identically: Poof, he appears, and says "I felt X". I wouldn't assume by default that two wards that function identically would differ in such an important aspect. DOUBLE EDIT: It could easily be said that it makes political sense for Dumbledore to kill Hermione, as an attempt to frame Lucius. But then, if Dumbledore doesn't actually speak up against Lucius… It is complicated. But I still think Dumbledore is in trouble, just from the perspective of Eliezer taking a more serious, realistic look at events from canon.
3Intrism
Honestly, I think you're the one overestimating the Wizarding public. The arguments from the wards aren't bad ones, necessarily, but they're technical ones. They won't play well. At best, they'll turn into conspiracy theories. Most of the public is going to look at the scene and see Lucius triumphant and Dumbledore with a black eye, and make the obvious conclusion. It will still be basically the same in front of the Wizengamot. Having Hermione killed under his own protection means trouble for Dumbledore - it would be the second major security incident at Hogwarts in less than a month, and the first student killed in fifty years. It's not an impossible black eye for Dumbledore to overcome, and he could surely take it if necessary. But... Dumbledore doesn't have a compelling reason to take the hit. Framing Lucius is not an especially good motive, particularly considering that half of the Wizengamot cares not one whit about Hermione Granger's life or death. And, if he did want her dead, he could have avoided the fallout by sending her home over Spring Break with a snake in her trunk. The technical argument... is still a bit above the Wizengamot. They might understand, "well, because of the wards this should have been impossible," but this will translate to "Lucius Malfoy found a way to trick Dumbledore's magic" and not "Hmm. Should Lucius Malfoy and his hired help really be in the same weight class as the Founders' wards?" Finally, you're assuming that Lucius wants to clear his name. I don't think this makes very much sense, either. Sure, it's bad PR in many circles, but Lucius already has a horrible reputation, and I don't expect he'll be terribly concerned. On the other hand, killing a student right under Dumbledore's nose would be an excellent show of force, and it would impress people that he cares rather more about. It might be exactly what he needs, in fact - I imagine his credibility took quite a hit when Hermione Granger managed to escape punishment for an a

It was Quirrell in the books? And, lets face it, it fits fairly well if you assume he was the one targeting her from the beginning.

In canon, the troll was in Hogwarts already, because Dumbledore brought it in to guard the Sorcerer's Stone. If he did something similar in Methods!canon, then Quirrell could easily have taken advantage of this to escape notice by the wards.

No. In canon, there were two trolls. Everyone seems to forget this. But then again, in canon Hogwarts was never described as having the same kind of comprehensive ward system it has in HPMOR.

I haven't visited these threads for nearly a year; please forgive me if someone else has shared a similar prediction in the meantime.

I predict that Quirrell's goal is to start a war between magical people and non-magical people.

The student armies have been taught combat skills, organization, and discipline but they have not been indoctrinated. The text does not show that the student armies have been guided toward one faction or another within Magical Britain. Quite the opposite, they have been taught to work together across the 'house' lines that may have divided them in the past.

It would be counter-productive to prepare tools that could be as easily used by your enemies as yourself. So we may reason that all members of the student armies are already on the side Quirrell wants them on. One thing all members of the student armies have in common is that they are members of Magical Britain.

I have found nothing to suggest international tensions, so a war against another magical nation would be out of place in the text, as I understand it.

On the other hand, Quirrell had a downright emotional reaction when Harry declared his aspiration to be a scientist in chapter 20. After the end,... (read more)

I think Quirrell wants the leader of the magical side to be Harry rather than himself. Quirrell doesn't seem to recognize that Harry would side with the non-magical side instead. (Harry has noted some peculiarities in Quirrell's model of the world on several occasions, and based on Quirrell being both a Robin Hanson stand-in and Voldemort I suspect those peculiarities can be summarized as Quirrell failing to account for, for lack of a better word, "love.")

Agree that Quirrell doesn't recognize this; agree that Quirrell's model is peculiar in failing to account for, for lack of a better word, "love"; disagree that the latter is the reason for the former. I don't think Quirrell would be wrong in predicting that even many Muggleborns will join him.

I haven't been following these threads enough to know whether it's even worth spelling out the obvious theory of what the "power the Dark Lord knows not" is in the Verresverse, but it seems pretty clear that it's neither "love" as in canon nor "science" as Harry suggests (and Snape disputes) in Ch. 86, but Harry's belief that a good future can actually be made to happen (and is worth fighting for), i.e. an interstellar transhumanist rationalist ethical civilization that has left death behind.

The power the Dark Lord Knows Not is optimism?
6wedrifid
After thinking about this for a minute I have to confirm my first impression: This is nonsense. The Dark Lord knows craptons of ambition. Any definition of 'ambition' for which the Dark Lord does not know it is a ridiculous definition. And if we're talking about Quirrellmort we've even heard him share his ambitions. Maybe he has somewhat less ambition than Harry but that's not sufficient for the claim to be reasonable.
9Benya
*shrugs* So my opinion is that when one ambition is so much greater that the other isn't even distinguishable from zero unless you plot them on a log scale, it makes poetic sense to call the Dark Lord "not ambitious", even though I of course agree that Quirrellmort is ambitious compared to the median human. But if you don't agree that this is poetically appropriate, sure, fine. (I'll recall my disclaimer that I don't actually think that it makes sense to use just a single word to describe the concept -- seriously trying to do that strikes me as trying to make the discussion compliant with Dumbledorian thought-by-cliché.)
0Sheaman3773
I agree with the concept above. Moreover, so does Quirrell: Now, every model I've made of Quirrellmort's prior actions do show him making his own opportunities, but the point remains--none of those opportunities (that I've modeled, predicted, or learned about) have aimed anywhere near any kind of genuine improvement of humanity in the way that Harry desires, not even fixing the flaws he himself observes. They've all just been about him achieving power. This feels odd to type, but it feels as though Quirrellmort's ambitions are...shallow.

Thanks. My infatuation with Quirrell might have faded a bit due to inactivity, but that thread has mortally wounded it. This Hanson guy is so deeply unmarketable that he made me stop liking a fictional character that might have been based on him. The part where he marginalizes the suffering of rape victims and that fact that this site still associates with him solidifies the "Less Wrong is not a place I can bring people" feeling I've kind of struggled with for a couple years now. That's two cringe-inducing passages of text in one day. Honestly, I liked the one where Hermione died better.
[-]Discredited270

Robin often displays unusual confusions. I think that stems from a reliance on his explicit memory over implicit memory. If he doesn't have a theory to account for why society fails to distinguish songs by whether their lyrics are fictional, as we do with literature, then he considers that a puzzle to solve, even if he's never wanted society to draw that category to aid him in selecting songs.

So when Robin asks, "Why do we appear to value X more than Y", he's not making any claim about how he feels about X and Y. He disregards his feelings and intuitions, because they would mask opportunities to improve his explicit, formal, verbal, theoretical understanding.

This distinction between questions as a tool to point out when the audience is wrong and as a tool of apolitical inquiry closely mirrors the difference between questions as requests for favors and questions as inquiries. It's also similar to questions as argumentative challenges vs questions as inquiries.

The one about rape is the one that is likely to stick with me, The creepy face he makes in the picture doesn't help. To the sort of people with whom I aspire to keep company, insensitivity on certain topics signals lack of status, a lack of class. In coarser terms, he stepped in it.

I ask myself if it is enough that they are one of many groups who espouse a form of self-improvement. Could it ever be enough?

the utility of censorship is not exclusive to the situations described in that post. But in the end, no. This conversation didn't start when I issued a call to action, but when I expressed a difficult decision I had made for myself. I didn't know that people were reading it as a directive until someone pointed that out. Anyway, it's far too late to change: that rape article is over two years old. "Better late than never" doesn't mean that late is always good enough. In this case, it's definitely not. In a world with wishes -- but where I didn't immediately wish for a world without wishes -- maybe I'd wish that Less Wrong would be image conscious enough to distance itself from people who unapologetically marginalize the suffering of rape victims, maybe not. But the call I get to make is whether or not to facilitate the process by which my friends and the people with whom I would like to be friends forget that I have any contact with Less Wrong. It is not whether or not to facilitate the process by which Less Wrong rehabilitates its status as a haven for creeps, creep enablers, or creep apologists.

The chaotic and frankly insane responses to his posts makes me suspect that most of the readers are completely unable to divorce political and gut moral feelings from internal analytical processing.

I suspect many of the posters in that thread will simply refuse to give a numerical answer. This is a clear indicator of mindkill.

Or an issue of how most humans are not willing to signal extreme utilitarianism because it is used easily to portray people as cold and hard. Moreover, most humans don't distinguish between "things I say for signaling" and "things I say because I believe them." So there are a lot of reasonable explanations for this without it being mindkilling. Also, some people really are just deontologists. Not being willing to answer such a question makes a lot more sense if one has a deontological rule that rape is always bad and wrong.

When someone is controversial for the sake of being controversial, it would be foolish for them to not anticipate consequences like no longer being accepted in mainstream company. Or ever company one or two standard deviations of 'daring' away from the mainstream in some cases. I get that it take bravery to do this kind of thing. (Or it could take foolishness. I'm not saying that's what happened here, but I wouldn't tell someone who believed to to be so that I had strong reason to believe they were wrong: I don't know the guy.) But being brave isn't a free pass to not deal with the consequences. And sometimes those consequences mean you aren't able to do as much good (or as much whatever you want) as you otherwise might. He took that risk in writing it. This site is taking a risk in continuing to associate with him. I am making the choice not to take the risk of reminding anyone not involve in Less Wrong that I read stuff here and sometimes post a trifle bit. Actually, thinking you can simplify and generalize human behavior down to rules like that is a clear indicator of mindkill. Let me break it down differently, not like anyone else is going to see this since they're all in the new thread. * Person A is hurt because their authority to control sexual access to person B is violated. * Person C is hurt because their authority to control sexual access to themselves is violated. Claiming equivalency between the injury to person A and the injury to person C is very insensitive. Hinting that person A's suffering is greater takes a few steps further. It's kind of dumb, too. The people I'm talking about don't shy away from rape. They might have, at one point, but one of them was a student to Craig Palmer, who has been rather vilified for writing a frank book on the topic. Yeah, it's an anecdote, but it's in answer to your anecdote for whatever that's worth.

I won't address the first part of your post; I think it is largely correct. We are, after all, responsible for our own actions. However, for the second part, I don't think that anyone is even remotely trying to claim the equivalency you're describing above. It's most definitely a straw man argument. If nothing else, the first claim should read more properly as "Person A is hurt because they have become legally responsible for a new human being and half of all associated costs and maintenance for that new human being for a period of no less than 21 years, in a situation where person A is not responsible for the creation of said new human being." After all, we are responsible for our own actions. Not necessarily those of someone else. (Side note: the 'control of sexual access' part doesn't make any sense, other than to construct a strawman. I don't understand at all why you felt that to be a legitimate argument or position.)

If you don't take some time to explore Robin Hanson's ideas in good faith you will miss out on a lot. What you see as a weakness is in fact his great strength as a rationalist. "Curiosity about humans and unconstrained by social norms." You may object, saying that you don't mind this, but any such response basically boils down to "I like X when it isn't too X."

The red flags aren't there because he is unaware of their existence. Indeed I bet Hanson can win quite well at social games. They are there because he systematically relies on his explicit/theoretical rather than implicit knowledge to expose where the gaps of the former are and then tries hard to fill them.

A nice touch when Harry is fighting the troll: When he engages his killer instinct, from then on the troll is only referred to as the "enemy", in one case even with a capital E.

Interestingly, while Harry explicitly mentions "censors off" (concerning no more screening off of potential killing methods), that mode of thinking also engages other filters, dehumanizing (de-troll-izing) the creature he's fighting and only seeing it as "the Enemy".

Two interesting observations: The most recent utterances of the words "temporal pressure" (similar to the titles of these last two chapters) was in chapter 86 when discussing the Halls of Prophecy:

Merlin himself had wrought it, it was said; the greatest wizard's final slap to the face of Fate. Not all prophecies conduced to the good; and Merlin had wished for at least those spoken of in prophecy, to know what had been spoken of them. That was the respect Merlin had given to their free will, that Destiny might not control them from the outside, unwitting. Those mentioned within a prophecy would have an glowing orb float to their hand, and then hear the prophet's true voice speaking. Others who tried to touch an orb, it was said, would be driven mad - or possibly just have their heads explode, the legends were unclear on this point.

I was under the impression that "temporal pressure" referred to some kind of mysterious Fate-like force that occasionally compels seers to release prophecies when important parts of the future gets resolved. That could just be Harry's new resolve to do anything necessary to get Hermione back (in addition to "time pressure" meaning the pressure he was under to get to Hermione on time). Is there a particular reason the "fracturing feeling" needs to be externally imposed rather than, y'know, a perfectly reasonable emotional reaction to current events?

On the other hand, Eliezer has mentioned that he wants to go through common tropes but do them better. He hasn't really done a full-blown Peggy Sue yet, although he's poked fun at the idea, and I'm pretty sure I remember Eliezer saying that he's read Harry Potter and the Wastelands of Time, which is a Peggy Sue fic in which Harry finds Atlantis and weird things happen involving time, so... (recommended for the awesome ideas, but if you're like me you'll get annoyed by the way Harry talks.)

Eliezer I think the facts at least are as described. Hermione is certainly lying in a pool of blood, something significant did happen to her (Harry felt the magic), and Dumbeldore definitely believe Hermione is dead. If there is a time turner involved, it won't change those perceptions one bit, And I doubt Dumbeldore would try too Mess With Time ever again (as mentioned in the Azkaban arc). Harry might, but he's out of his Time Turner Authorized Range. Even then, it looks like he's thinking longer term than that.

Making Hermione a horcrux in the last 6 hours of her life doesn't violate any observed facts.

Although I'm not at all sure it was deliberate (is there a way to submit potential typos?), we may have just gotten some new evidence about the true nature of magic. In Ch 89 Fred/George cast a spell solely from the memory of seeing Dumbledore cast it ("Deligitor prodi"), got the incantation wrong ("Deligitor prodeas"), and yet still achieved an (apparently) identical effect (The summoning of the Sorting Hat). It appears that if this is legitimate evidence rather than a typo, magic has an error bound for the correct pronunciation of spells.

Reply
[-]pedanterrific110

"Prodi" is the imperative ("come forth"), "prodeas" is the subjunctive (here used in supplication, for which there is no precise English translation; perhaps "wouldst thou come forth").

Which itself suggests something quite interesting about the nature of incantations... unless it's not actually an incantation, just talking to Hogwarts in Latin.

Reply
3somervta
Well, in the first usage, Dumbledore did seem to be addressing Hogwarts ("Hogwarts! Deligitor prodi"), so it's possible, but Fred/George didn't do that. I suppose it is possible that Eliezer just used the subjunctive form rather than the imperative accidentally, but I'm not sure if I want to count on that :D
7tim
Note that this seems to contradict the glowing bat experiments performed in chapter 22.
5somervta
It may be that this is only true for some spells? Although, to be honest, I'm leaning towards it either being a typo or not an incantation, just communication with Hogwarts.
4JoshuaZ
If doing magic for more time makes one stronger (which seems to be a hypothesis taken seriously in HPMR), then it is possible that as one gets more powerful, the increased power can compensate for the incorrect pronunciation. In fact, this also may explain to some extent how less powerful witches and wizards can't cast some spells. In some cases it may be that the orally transmitted version of the spell is not quite right, but that doesn't matter as much for the more powerful spellcasters. A problem with this hypothesis is that one would then expect there to be weak spells which could only be cast by powerful mages and we haven't seen any indication of that.
3Eugene
Point against: Professor Whatsisname, the presumably quite-powerful dueling legend, learned/developed "Stuporfy", which is intentionally meant to sound almost exactly like "Stupify". If powerful wizards get a pass on their pronunciation, how is it that a powerful wizard can effectively differentiate those two similar spells when casting?
1JoshuaZ
Yes, that undermines the suggestion considerably.
1drethelin
This might be different when you're manipulating unthinking magic system rather than addressing a sentient entity such as the sorting hat.

Most of the plans to use time turning to fix this are massively overly complicated, by the way. Best bet is to swap the oxygenating potion for something which will make her death less permanent.

Which Harry can find or have made in < 6 hours.

Options: 1: Elixir of life. The stone is at hand, Snape is at hand. It is possible that shout is what taking it looks like. 2: Undeath. The potter verse does have vampires, and they are integrated in magical society at least to the extent that seeing one in a bad neighborhood is not grounds for an auror raid. Werewolf infection might also do it. 3: Draught of living death?

Well, at this precise moment Harry cares rather a lot more about moving her out of the "Dead" state than he does about rendering her immortal, so if vampires have a finite lifespan, that is not an unacceptable drawback at this particular juncture. (.. and would outright be an advantage if it means she gets out of being stuck at age 12. Not that having her stuck at age 12 would stop Harry. That can be fixed when he is not staring down a 6 hour timer) Further upsides; keeping her rising on the quiet would shield her from repeated attempts at ending her, if he can swing that. Likely downsides: 1:Feeding. But there has to be an acceptable solution to that, or the magical community would not tolerate vampires at all. On the other hand, the wizarding world generally fails ethics 101 very badly, so maybe they are just all hypnotizing people into being faux-willing donors. 2:Might no longer count as a witch. Giving her the brick powerset of a stereotypical vamp would be a hilarious mismatch for her personality. That all assumes vampires have continuity of personality with who they were, but if that is not the case I would be somewhat puzzled why they are tolerated. Also, that turning her is workable. If the process of becoming a vampire takes a year and a day or requires her to die from a vampire bite..

Nothing to do with psychopaths, but regardless: it is predictable, medically treatable in canon, and also easily neutralized by ordinary mechanisms of confinement. If that were a method of immortality, I'd do it in a heartbeat.

If you ran the numbers, would regeneration from injury at the cost of losing human thought for three days a month* actually be worth it for most people? So far as I know, being a werewolf doesn't help with aging. I'm not sure if there's a default for whether it helps with illness. *more or less. I think that some versions only become wolves at night.
2gwern
I did say it'd be a complete no-brainer for immortality, but if we rule that out... In HP it's just one night, IIRC (discussed in Azkaban). Regeneration from injury is probably not worth sacrificing 1/60th of a life (month has 30 days, you lose a night from a day, hence 1/60), but it is probably worth chugging the wolfsbane potion depending on costs. If being a werewolf fended against generic disease, not just injury, then it'd resume being a complete nobrainer.
0Eugine_Nier
What Nancy said. Also given Moody's paranoia, being dependent on something so easy to sabotage for one day a month is a huge downside.
0MugaSofer
Well, sure it doesn't. It just prevents you aging, while giving you a vast suite of easily-exploited, well-known weaknesses - some of which appear to be psychological blindspots/compulsions, and the rest of which instantly and permanently destroy you, and are easily duplicated (but not easily negated, for the most part) via magic. Oh, and your STR and DEX scores go up a bit, I guess. Disclaimer: This assumes MOR!Potterverse!Vampires don't run on the Buffy you-get-replaced-by-a-demon principle or the Anne Rice tortured-romantic-deathgod principle, AKA Twilight Syndrome - but still retain most of their standard pop-culture properties (as do most Potterverse creatures that aren't original creations.)

Wild Mass Guessing (that I don't believe in, but would be cool):

That would imply that only an attempted murder can create a horcrux. With the right self-delusion or whatever, one might be able to mass-produce horcruxes and train an army capable of ruthless action at the same time.

[-]skeptical_lurker170

I'm mildly surprised no-one has speculated on what Harry will do next. He won't accept that Hermione is dead, and I'm guessing that it will occur to him that transfiguring her into a steel ball and then freezing it (I'm pretty sure there's a spell for that) provides a quick and easy form of cryonics, which as an added bonus bypasses the problem of ice crystal formation.

How to resurrect her is the tricky bit.

Reply
[-][anonymous]110

I would nominate the Blood-Cooling Charm as a convenient and adequately-foreshadowed first response. Like packing a recently-deceased patient in ice, that will buy her enough time until she can be properly cryopreserved. That is, literally stuffed in the fridge. One of the FFnet reviewers had it right: this chapter was an epic troll.

ETA: Gah! Bleugh. There's just no getting rid of the taste of a wrong prediction. It's like a mouth full of soy sauce.

Cryonics doesn't work on someone that's already dead, and Harry's not so distraught that he won't recognize that. I also don't think Harry can sustain a transfiguration like that for long without exhausting his limited supply of magical energy. Harry has evidence that some soul-like thing left Hermione's body, so if he wants to revive her he needs to get it back. I vote for reverse-engineering Time Turners and doing some more substantive kind of time magic, since that would also serve many of his other goals, although maybe Eliezer will prohibit that because it would allow him to get too powerful too quickly.

[-]Benya240

But for your reasoning upthread to work, Harry has to be so sure that the outpouring of magic carried all the information about Hermione that it's not worth it to him to try and protect her brain, and with (a) his protestations that brain damage means that the information must be in the brain and (b) there not being a shred of evidence that I can remember off the top of my head that Muggles require any magic to run (in which case witches/wizards' brains/souls would presumably have to work completely differently from Muggles), I don't think Harry is at a point where he can conclude that the chance of reviving her by saving the body is so low that he should concentrate his efforts on chasing her souly-looking emanation of magic.

Harry currently thinks that Atlantis is some form of system that locks onto human bodies with the Blood Of Atlantis gene and detects their commands (spells, odd potion-making actions, etc). A simple explanation for Horcrux is that it is basically a form of uploading. Although that would make it seem overly simple for Sufficiently Creative Harry to find a way to make horcruxes without human sacrifice. Alternatively, a wizard's soul has read-only access to their brain.

I'm not claiming that recoverable info-containing souls are a completely crazy outlandish hypothesis; I merely claim that Harry is nowhere near having enough support for this hypothesis to stake Hermione's life on it being true.

(Assuming that you meant to say "still alive" and interpreting this as "had ever been done on somebody who wasn't clinically/legally dead"; not sure that that's what you meant, but if not, I don't understand your comment:) Qiaochu has already explained that he was talking about information-theoretic death there. (ETA: If you meant that nobody's actually been brought back to life, that still doesn't seem to conflict with the correct-by-definition claim that cryonics doesn't work after information-theoretic death.)

While I agree with the rest of the comment, this part is strictly false. We know that Harry can sustain a transfiguration roughly like that indefinitely, as evidenced by his father's rock.
2Qiaochu_Yuan
I would be surprised if it took comparable amounts of magical energy to keep a rock transfigured vs. a human body, but who knows how the energy requirements of transfiguration really work.
4ygert
I thought it worked by size? I'm pretty sure that was stated earlier in the story. And I'd imagine that a boulder like Harry's father's rock could be roughly a similar size/wight/mass to a 12 year old girl.
1Qiaochu_Yuan
Hmm. My guess, based on the kind of logic that seems to govern most magic, would have been that the amount of magical energy required has something to do with how different the two things you're transfiguring between are. But again, who knows how the energy requirements of transfiguration really work. I was also under the impression that Harry had to keep the rock with him at all times to keep it transfigured. Would he also have to keep Hermione with him at all times? Also, the transfiguration stops if Harry exhausts his magic for whatever other reason, and I don't think he'd want to risk that happening to Hermione.

Magical exhaustion would mean cutting off his finger with a restored Hermione. That's why the rock was transfigured into a jewel and not a ring.

I’m not trying to imply anything naughty here, but Hermione is somewhat softer than that rock. (Until you see her angry.) Not to mention he doesn’t have any obvious need to keep Hermione on his finger all the time, unlike the rock. Just long enough to find some safe spot to hide her.

As far as I can tell, transfiguration mana requirements are based on the size of the assumed form, and there can be a huge size change (such as a 20 kg? rocket from a small ice cube taking a long time) and the very easy partial-transfiguration slicing. Harry doesn't need to keep the rock at all times. He just needs to contact it more often than once every transfiguration duration.

People believed for a long time that cessation of heartbeat is irreversible. While this is less likely to be such a mistake (wizards have some stasis spells for medical use, so at least sometimes they would have more time to assess whether anything works on such a supposedly dead person), it's still possible. Also, I'd like to posit this: this is the moment the magic decides the person is no more and from this point on any magic that works on a person won't work on him/her. But, nonmagical intervention and spells that aren't designed to target a person could still reverse it.
7skeptical_lurker
This is a good point, and furthermore in the story it goes straight from Hermione saying her last words to her death , whereas in real life I believe if circulation stops instantly (which isn't exactly the case here) you lose consciousness within 15 seconds, but it takes 4 minutes before brain damage starts. Which means they still have time to perform a blood transfusion and try to save her. More generally, has any wizard/witch ever been brought back after their heart stopped? Does the soul reenter the body? If not, do they end up in a coma, or do they maybe get a new soul? Even if wizards do not practice cpr, surely some wizards would have had heart attacks while in the presence of muggles.
2Roxolan
CPR started to spread in the 1960s. Given how few wizards there are, and how little time most of them spend in the company of muggles, my no-actual-math-involved guess is that it isn't that likely.
2skeptical_lurker
I seem to remember that the wizard population of the UK is about 10000, which would extrapolate to 1 000 000 worldwide. Given that many wizards do have muggle family... Ok, some math - conservativly speaking, if 10% of wizards have contact with muggles, and spend 1% of their time in the company of these muggles, with an average death rate of .6%, 40% of which is by heart attack, but only 40% of heart attacks are fatal, and 10% of the times that a heart attack happens in the presence of muggles the wizard dies and then the heart is restarted, then there would be an average of .6 wizards being brought back from the dead per year. But more to the point, surely some muggle-born wizards would practice cpr, or even improve on it using magic? With a population of 1000000, surely someone sometime would have transfigured a defibrillator in an emergency?

From Chapter 56: It would have had to have been a different cloak than Harry's, but then, I guess Hermione did have one on her; it might not have been good enough to hide her from the troll, but perhaps it would have hid her from Harry.

Hmmm... it's also possible in that scenario that Hermione was hot-swapped out of the combat. Real!Hermione responded with a terrified scream to the Patronus, and while Present!Harry was racing to her on a broom, Time-Turned!Harry did some kind of obscuring spell (fog, blast of light, something like that), tossed an invisibility cloak (not Harry's) over Real!Hermione, and then fed Simulacrum!Hermione to the troll just in time for Present!Harry to show up.

Every consistent theory I've seen involves time-travel somehow. The stakes are simply too high for Harry to permit the attempt to not be made.

It's plausible that having one's Patronus dispelled by one's future self is not as noticeable as having one's Patronus countered by a killing curse. Alternatively, an even simpler option is that it was still Present-Harry's patronus, just given updated instructions by Future-Harry.

Narrative convention suggests it's awfully unlikely that Eliezer would drop a bomb like this with an update gap in between if it were a false alarm.
1skeptical_lurker
Even if Harry now believes in souls (and what happened to Hermione looks to me like magical death throws, if I was Harry it would be insufficient evidence to overcome my priors) then surely he would want to preserve her body so the soul has something to occupy? Maintaining the transfiguration is easy, keeping it cold is harder as you would have to repeatedly cast the cooling charm, but I doubt the internal structure of a strong metal changes much over time even at room temperature, and he would ask Quirrel for help, because adult help will probably be needed anyway for recovering her soul. Quirrel will be delighted to see Harry devote himself to the magical conquest of death. As for time turners, being able to go back further than 6 hours and change history is an instant victory, unless both sides have them, in which case the story changes completely into a time war. I don't think that's where EY wants to take it, unless maybe in the last chapter, post-magical singularity, they travel back with invisibility cloaks and save everyone who has ever died.

Possibility: Normal harry and his Dark Side have now merged (or Harry has lost his restraint to the extent the distinction is irrelevant). This new Harry has all his abilities and none of his previous restraint and is effectively a new person, with the expressly stated intention of changing the world that now exists to the extent it is effectively destroyed.

Secondary possibility: The current 'world' will end because Harry is going to somehow turn back time and destroy thus timeline in its entirety.

Even if it was about something different. 'he has come' in the last prophecy implies that he had just arrived. Point two: Voldemort appears to love destruction. I still don't know how someone as intelligent as him hadn't killed everyone in the ways Harry thought of -. Harry's intent to kill, which is presumably very Voldemort-like, is extremely creative and effective even at his magic level and age. But assuming that Voldemort is about destruction, he might want to end the world. Quirrell or someone (e.g. Snape) might have resurrected Voldemort right after stealing the Philosopher's Stone - a time-turner may be involved.. Dumbledore was away, Snape might be unreliable, it could have easily happened. A counterindicator is that Dumbledore is probably also aware of this risk, and therefore might have taken counter-measurements, although we can see that Quirrell can fool him in the part where he learns about the zoomagus potion left in Bellatrix's cell (though it portrays himself and Snape as significantly inferior to Voldemort and Quirrell, so I'm reluctant to believe it was real, rather than them acting in front of McGonagall).

Good reviews of bad movies are almost always worth watching. See, for example, 90% of the Nostalgia Critic's work.

Errr... "almost always worth watching"? Lots of things are "worth" doing insomuch as they are more enjoyable/valuable than picking an action at random... I'm interested in whether things are relatively worth it. And I'm pretty sure that the decline of marginal benefit would tank the Nostalgia Critic's work within 10 reviews, probably sooner. And even then, is that going to be more enjoyable than . What lukeprog's comment demonstrated was that this wasn't just another instance of "omg you have to watch this" which is a pretty common phenomenon, and is probably biased because, content aside, we want our friends to consume the same media as us. Luke was in a similar position to mine and he recounted being grateful for choosing to watch it. This feels like it offers more support than if he'd said "Oh yeah, I've seen that video and it's great" because in that case, it's much more likely that Luke is already the sort of person who watches those videos, in which case there's a bias towards him enjoying them. I'm finding myself somewhat worried that somebody's going to come along and jokingly comment "haha, thanks Alsadius, I just went and watched 90% of NC's work, and it made me laugh pretty hard." So I'm just gonna preempt that here. If someone actually does that, link to your favourite 1-2 videos, because I don't want to watch them all.

So there's already a resurrection ritual that Harry has heard about. Blood of an enemy, bone of the father, flesh of the servant. Can he find these things for Hermione?

Anyone else confused by the line in chapter 89:

"Lead it away, keep it off me," said a voice.

On first reading I thought it was the as-of-yet-unnamed-but-totally-Hermione victim, which seemed odd, but on a third read I think it might be Harry, and the distance of the narration just a reflection of Harry's horror. Not sure, though.

In canon this ritual is used to give the Horcrux-preserved shadow of Voldemort a new body. His body has the shape of a human baby and is able to talk coherently; he reemerges after the ritual with a fullformed body. Hermione has got no Horcrux of her own, and is thus beyond the means of this resurrection ritual.
3MalcolmOcean
Based on main canon, I don't have the sense that that resurrection ritual works for someone who's properly dead.

I'd expected this to be spoken by Harry under his cloak (thus `a voice') when I read it. I still think it was Harry, because it makes perfect sense for him to say that (he wishes to attend to Hermione as soon as possible) and it's awfully coherent for someone going into shock.
0[anonymous]
Usually when Eliezer writes the words "a voice" it occurs in a phrase like "he said in a voice so malevolent it could boil kittens' tears". Occasionally he writes "a voice" just because the person whose perspective he's writing from doesn't know who was speaking, like "asked a voice from clear across the room" or "shouted a voice somewhere in the mists of the battlefield". This doesn't look like either of those. It's not a strong clue, but to me it points in the direction of Eliezer intentionally not naming who spoke, in order to keep it a secret from the reader for the moment. Or maybe I'm getting carried away hoping there's an invisible time-turned Harry there to save the day.
2linkhyrule5
He can try, but, well, Voldemort's soul was still around. :(

He would have needed to kill somebody, possibly to have killed somebody with mens rhea, to do that. Of course, Harry might get around this. Bone is a problem since Harry's father is alive. Plus it must be unknowingly bequeathed. Perhaps he could steal it, and it would be OK? Perhaps Harry's father will die at some point? Perhaps a different ancestor? Not necessarily father. Who is his servant? I don't think he has one. The closest would be Lesath Lestrange or maybe the Weasleys. Enemy would probably be Quirrel. Harry might be able to acquire his blood.

You say that like having an immortal soul, a major part of your mind that can survive literally anything, would make it harder to revive the dead.
2Vaniver
Right, for some values of "revive." If the immortal soul has a mortal connection to the real world, then you can either revive the bodies (but they're soulless) or you can bring back the soul (but they're disconnected). The Resurrection Stone in HP canon (as well as possibly that creepy curtain) suggests that the second option is already implemented, but doesn't establish that it's the best possible (except in an 'absence of evidence is evidence of absence' sort of way). If people are just computation, then you only have to solve the problem of fixing the hardware and rebooting them, not also realigning their soul.
8RomeoStevens
Humans can still be just hardware with a soul. API calls to the cloud.

Sure- but in a world where souls are immortal and connections can be easily be restored, that sort of resurrection would be likely to already exist. Its absence suggests its impossibility.

Reread the event in question. (I'm trying to keep the start of my comments a little unspoilery, since they show up in the recent comments sidebar.) In the universe where souls do not exist and people are just electrical activity embodied in lipid computers, that description and it triggering Dumbledore's immediate arrival seem very unlikely. In the universe where souls do exist, it seems very likely.
1Qiaochu_Yuan
Oh, hmm. For some reason I thought Dumbledore's arrival was triggered by the wards. Gotcha. But I think what Harry witnessed was still consistent with magical echoes; it sounded like Hermione almost but wasn't quite made into a ghost or something.
[-]Vaniver200

Oh, hmm. For some reason I thought Dumbledore's arrival was triggered by the wards. Gotcha.

Right; I'm using the wards triggering right then as evidence for the souls theory. In a souls world, it's easy to notice when souls exit the body (and set up wards to detect that), and hard to notice when souls are about to exit the body, so you can show up and suspend them or whatever. In a 'people are just computation' world, where you're able to read the computation from afar using magic, a ward that notices "Hermione's not alive anymore!" would require tech that could be used to build a ward that notices "Hermione's going into shock!", which would be a much more useful ward to have.

[edit] I didn't fully remember the wards from the Draco Incident, where they could detect injury. So either there are multiple levels of wards and the injury ward was disabled (or set to death), Dumbledore didn't respond to the injury alarm but did respond to the death alarm (reasonable, if he's somewhere else important, and the Deputy present at the castle would have already known the troll was around and have the castle in high alert by the time Hermione was attacked if she was attacked after Filch's alert), there's a continuity break, or something I'm missing.

Reply
[-]Qiaochu_Yuan120

Good point, but I'm not sure if the wards triggered right then: Dumbledore said he felt Hermione die, not that the wards alerted him that Hermione died. During the Draco fiasco various characters say the wards are triggered to detect rapid harm to students, which is why they didn't detect the blood-cooling charm (although you'd think that means the wards would have detected what happened to Hermione sooner...). The implication is that if someone hadn't discovered Draco he would have died without the wards detecting it, or at least that's what it sounded like to me.

We don't even know Dumbledore was in the castle, as I understand it. Ch88: If he's not even at Hogwarts, that seems like it renders it difficult to infer anything from when he shows up since any delay or argument-from-silence could just as well be due to it taking time to phoenix-fire back from whereever and then repoint himself.

The wards triggering right then is evidence mostly that somebody is messing with the wards, based on their previous description as being set to trigger on "sudden injury".

The clear intent of the Blood-Cooling Charm had been to kill Draco Malfoy so slowly that the wards of Hogwarts, set to detect sudden injury, would not trigger.

3Jurily
Or that since she ran for sunlight, she wasn't inside Hogwarts technically, therefore the wards didn't pick up her injury. We already have proof the attacker expected her to do that. Which would also explain her last words.
2Fhyve
She was still within the wards/within hogwarts grounds.
2Vaniver
Oh! What if the wards only work inside the castle? Hermione's battle with the troll was in the sunlight and thus outside. While I would hope that the wards would cover the entire school grounds (rescuing students from the Forbidden Forest seems like a more common use case than rescuing them inside), that's another possibility that seems somewhat more reasonable than some of the others I've listed. (I should also, for completeness, add the "he responded to the injury alarm but it took too long" option, but I find that one unsatisfying for several reasons.)
2Alsadius
The wards were drawn up by a schemer in the 12th century. Was shock a concept he was familiar with? (Gryffindor probably would have been, but Slytherin, I'm not so sure)

Possibly not. But as Hippocrates put it, and so I suspect that trauma surgery was mature enough then that they had some concept of shock after seeing hundreds of people die from it.

Agreed. Salazar Slytherin doesn't seem like someone who has seen a terribly large amount of war, though - he's more of the shadowy type. That said, thinking and a bit of Google reminds me that Ch. 47 has Salazar Slytherin in a battle scene. I'm no longer confident of the correctness of this point.
5drethelin
He felt something "happen" when Hermione died and Dumbledore also confirmed it. It might just be a magical echo but it's definitely evidence for something like a soul.
6CAE_Jones
This is true, but without further investigation, it fails to distinguish the world where souls are independent from physical form from the world where souls are magical echoes/uploads/backups/etc. On that note, this would be one convenient time for Quirrel to drop in and say "Oh, by the way, that description of the Resurrection Stone you gave me turned up something interesting..."

Harry knows how smart Quirrell is, and he knows that if it occurred to him that the troll was an attempt on Hermione's life, it would have occurred to Quirrell instantly. We (and Harry) know that Quirrell said nothing to McGonagall, from which Harry will soon infer that Quirrell could have saved Hermione yet did nothing. (Which makes it likely, but not certain, that it was Quirrell who was behind the troll.) In either case Quirrell has reached a point, or is about to reach a point, in his sinister plan where it no longer matters (or perhaps even requires) that Harry take him as a mortal enemy.

Draco (and maybe even Lucius) will most likely infer from the troll incident that Hermoine was not the one who attacked him, and he will align himself with Harry in the coming Roaring Rampage of Revenge. I would not be surprised if Lesath Lestrange also made an appearance.

It's also possible/likely that the Malfoy household is either involved, or believes that one of their allies is involved, in a revenge killing.
1JTHM
It could be House Malfoy and Friends, but if so, we would still need some reason why Quirrell would not have told McGonagall that the troll was likely after Hermione. If Quirrell did want Hermione dead, he would most likely have kept any other potential murderers away from her so that her death could occur at a time and in a manner that would suit him best. So the most probable explanation is that it was, in fact, Quirrell.
6Decius
McGonagall is savvy enough to know that the current defense professor is at fault for something like this; Quirrell pushed his luck in manipulating her into taking the actions she did, including providing him a single point of false-memory charm to an alibi for whatever he needs to do (including stealing a time-turner, meeting his future self, confirming that everything appears to will have gone well, and then going back to set up the scenario in the first place). ETA: And even if it wasn't Malfoy & co, it is believable that they would think it was one of them.

Quirrel didn't know that Hermione was missing when he left with McGonagall.

The assailant in question introduced a troll through the school wards, enchanted it to resist sunlight, disabled Hermione's cloak & broom, arranged for it to be in the same part of the castle, made the troll eat Hermione's legs to disable her portkey toering, and is apparently responsible for Fred & George no longer having the Marauder's Map which real-time locates every student in the school.

Seriously? Of course the attacker (Quirrel) knew she wasn't in the hall.

thanks this makes it clear that it was aimed at Hermione.

I don't accept that Quirrel is necessarily the attacker, but more to the point, I meant that Harry wouldn't know Quirrel would know Hermione wasn't in the hall, so he wouldn't expect Quirrel to behave as if he knew.

Even if Quirrell weren't responsible, he would almost certainly have the presence of mind to quickly check whether any high-value targets (Harry, Hermione, and possibly Neville) were missing. Harry manages to do the same, albeit after some unwarranted delay; he would not expect Quirrell to forget it.
1atorm
Maybe. Harry didn't remember to check until after Quirrel had left. I think it wouldn't be hard for Quirrel to convince Harry that as soon as he realized Hermione was in danger he came as fast as he could, especially since he really DID burn holes through Hogwarts to get there. He will need a believable explanation of how he knew where to go, though.

I'm tentative to make predictions here since, reading through comments, I consider you folks more grounded in rationality, logical thinking and also fictional predictions than me. But I wanted to share a thought and get feedback, so here goes.

My interpretation of the big magical release goes like this: Hermione's brain, experiences, knowledge, magical ability, etc., are programmed via the genetic magic marker to upload into... something. The Atlantean Neural Database, or something like that. We've got reason to believe that magic was artificially created and the genetic marker programmed into people, so that they are capable of interfacing with reality on a far more interesting level than most people. We've also got plenty of evidence to suggest that the brain is, if not fully understood by magical knowledge, more than capable of being interacted with. We have Legilimency and Obliviations capable of accessing memory, thoughts, knowledge, and intentions; the author is capable of working with things WE don't know about because wizarding knowledge is stated to have been lost, so we also have some unknown-unknowns working against us. So the odds of neural magic having existed in ... (read more)

I predict that Harry will save many or all people who ever died from oblivion with magic that reaches backward through time to capture the mind of each person at the point of their death.

I further predict that this magic will create the mechanism of magic, possibly incidentally, and be responsible for the sort of Atlantis that magical Britons believe in.

I speculate that magic and ghosts are unintended byproducts of Harry's Afterlife Immortality Project.

Harry is an anti-death hero. Whatever villains he may encounter, his enemy is death and his heroic victory will be over his true enemy.

The afterlife figures centrally in the original work in ways that are incompatible with the author's worldview. In this way, the author incorporates important elements of the original work without betraying his convictions.

I made this prediction last April, and wish there had already been an admonishment to share predictions like the one involving 75th, yesterday.

I don't know what "just complex enough" would look like, so I'm not sure what you mean by overly complex. But I promise I will listen. It has been established that the past cannot be changed because the universe steps through time once, with all time travel included. Harry cannot change the misery that occurred. On the other hand, the author has said something to the effect that even if there is an afterlife in HP&tMoR, there is no evidence of one so someone like Harry would not believe in one. Without evidence of an afterlife, Harry can create one that has always existed and contains the minds of many or all people.

Prediction for Chapter 90: Time Pressure, Part 3:

"Wait a moment," you say. "Time Pressure, Part 3? Harry already lost his race against the clock. Why would Chap. 90 be called 'Time Pressures'?"

Because Harry's race against the clock to save Hermione's life has only just begun, and he has slightly less than six hours left. Eliezer mentioned that one of his most significant purposes of Chap. 86 was to update characters' states of knowledge before the next arc. If you recall, in that chapter, Harry learned the word "horcrux." And in Chap. 87, Harry learned of the philosopher's stone.

So what will Harry do? Get the shell removed from his time turner, or obtain a time turner from someone else. Learn about the Horcrux ritual as quickly as possible, travel back in time, get Hermione to create a horcrux, and erase her memory of doing so thus that her death plays out just as before. Then start working on the stone to restore Hermione to life.

While I consider this unlikely, it would help explain the scene with Hermione's soul seemingly leaving her body. As far as I remember the characters who deaths seems we saw in canon didn't have this effect and having a Horocrux would differentiate Hermione from them.
5bramflakes
I'm not capable of reasoning about time loops in my sleep-deprived state, but would it be possible for Hermione to create her Horcrux by killing herself?
8JoshuaZ
Yes: Consider the following loop: Hermione A goes and kills future Hermione B (who already has a horcrux). Hermione A is then killed by the troll, but has a horcrux (possibly with a mind wipe before so she doesn't know about it). Hermione is then A is then resurrected to be sent back in time to become Hermione B. Then Hermione B is resurrected. However, we know that messing with time is bad and we know that magic with souls is powerful, so this combination looks potentially very dangerous.
3Vladimir_Nesov
More generally, if resurrection doesn't require additional sacrifices and doesn't use up a horcrux, people who don't have horcruxes could make them by murdering other people (by arrangement) who already have one (and then resurrecting them). Eventually, everyone is alive and has a horcrux.
0JoshuaZ
I'm not completely sure this will work in general. It seems that magic works partially off of intent. One may need to actually believe that one is murdering the person in a permanent way. However, even that could be handled with memory charms.

Predicted with what probability?
1JTHM
80% probability that Hermione will make a horcrux; a mere 30% probability that everything will happen exactly as I specified above. It is a very specific prediction, after all. ...And a 90% probability that the plan will occur to Harry whether or not he pulls it off.
3elharo
I can't see either Harry or Hermione going along with a Horcrux ritual. Just too evil and out of character for both of them. Given the title and some other hints in the story, I think use of a time turner is inevitable; but whatever Harry does it won't involve a Horcrux.

Not out of character for Harry; in fact, it would be perfectly in character for him. But Hermione would never go for it.

First, I have to get the emotional reaction out of the way: holycrap!

Now that that's done, is the last time we've heard about the Marauders' Map when Dumbledore borrowed it to search for Tom Riddle? I don't remember off hand whether that was after TSPE or in Taboo Tradeoffs.

I'm a little perplexed at how Harry's medical treatment didn't seem to work; it sounded like it should have bought several minutes, but the action that followed didn't seem like it could have taken more than 60 seconds. I've only read it the once through, so I could be missing it completely, but the timing felt deliberate. (And all the ticks in 88 seem to emphasize the passage of time, though they could well have just been to emphasize the pressure).

Also, Susan knows how to effectively magic giants? That makes her smarter than Umbridge's entire team-to-sack-Hagrid in canon. I suppose it pays to have a competent defense professor (even if he is the most likely suspect for all the awful that just happened), and the director of the DMLE as a close relative.

Re Marauders' Map: Quirrell pretty obviously has it. He obliviated the Weasley twins and took it. This is just the smart thing for him to do.

Note how he's burning straight through to the melee with the troll at the end of Ch. 89 - so he knows exactly where and in what direction Harry and Hermione are. This could also be because of the psychic link, but it also increases the probability he has the map.

Reply
3pjeby
Alternative hypothesis: this is one of several things done by a time traveller creating a consistent time loop. If they had the map, it would have shown Hermione in two places, or else not where she was being attacked. In this scenario, the twins were temporarily obliviated about the map, just so they wouldn't use it. But they still have the map. The disappearance of the map is actually one of the few clues that IMO raises the probability that a time loop is already in progress, besides the ELIZA discussion with "Brienne". Harry also knows that the time turner prohibition can be defeated, with assistance from an adult wizard; his likely next effort (after securing Hermione's body for possible revival) would be to find another way to circumvent both the use prohibition and Time itself. But I guess we'll find out in a few hours. (Squee!) (Not an actual prediction, but it would be awesome if this somehow turns out to be Hermione deliberately faking her own death to assume a cover identity. Among other things, it would be a compelling answer to the "stuffed in a fridge" trope allegations. Not as powerful -- but still more fair to Hermione than the status quo -- would be a flashback that shows her heroically taking on the troll in order to protect someone else, rather than just being a victim. She at least deserves her own epic batlle scene, even if the story requires it appear only in flashback.)
2Qiaochu_Yuan
You don't think Dumbledore would've obliviated the Weasley twins after using the map to find Voldemort? That would also have been the smart thing for him to do.
7Intrism
Nah, not really. The Marauder's Map is the obvious thing to try when searching for someone in Hogwarts, he wouldn't release any information to the Weasleys. And, of course, Dumbledore does trust the Weasleys. It did suggest the Map to Quirrell as a device he'd want to confiscate, but it's not really in Dumbledore's nature to think that far ahead.
4maia
I guess the question is, how many levels deep is Dumbledore playing? I think it's possible he's smart enough to predict that Voldemort would do this, and take the map away from them as a precaution. But not super likely. But other than that, I don't see a motivation for Dumbledore to confiscate it; he seems to like that the Weasleys have it. It's a token of Gryffindorishness, flouting the letter of the law to pull pranks and help out their friends or what have you. And Dumbledore likes that, I think.
3Qiaochu_Yuan
Right, but Dumbledore also thinks there's a war going on. The map seems like too useful a tool for either side to have for Dumbledore to be so cavalier about leaving it in the twins' hands.
5Intrism
I would understand Dumbledore confiscating the map. But, if he were to confiscate it, he would do only that, not Obliviate the Weasleys such that they'd have no memory of ever possessing such a map. It would seem cruel and pointless to him.
5Qiaochu_Yuan
Suppose Dumbledore thinks his enemies aren't aware that the map exists. If he believes one of his enemies is a Legilimens and is periodically scanning the students' minds, he might not want to take the risk of them scanning the Weasley twins and discovering the existence of the map. But I admit I'm stretching at this point.

Most likely. What I don't remember is whether or not Dumbledore ever gave it back to Fred and George; he presumably did if Quirrel stole it, since I doubt he would have had an easy time getting it from Dumbledore unnoticed. And if we didn't get confirmation that Dumbledore returned it, I suppose this might fuel "Dumbledore did it" theories. Most of my probability mass goes to Quirrel, though.
2maia
Yeah, I assume Dumbledore gave it back. He didn't care that they had it before he borrowed it; why would he suddenly begin to care after? (OK, I can think of a few reasons, but they're pretty weak and don't measure up to "Quirrell took it" in probability mass.)

My understanding is that once shock is refractory#Refractory), there is no turning back (in particular, oxygenation at that stage is useless). I'm not familiar enough with the medicine to know if it's reasonable for her to progress that far that quickly, but my layman's guess is "probably."
3Alsadius
The description of refractory shock is that the ATP in the body has already decayed and diffused out of the cells. Would someone in that state have any way of speaking? Or do we assume that the Law of Dramatic Death Scenes is written into a magician's powers?
4Vaniver
The dramatic death scene was my interpretation, but I don't have much experience with people dying violently (thankfully). I don't know how realistic dramatic death scenes are or how much wizardly fortitude is worth.
7loup-vaillant
Recalling a video I have seen (forgot the source), the actual damage wouldn't occur upon hypoxia, but upon re-oxygenation. Lack of oxygen at the cellular level does start a fatal chemical reaction, but the structure of the cells are largely preserved. But when you put oxygen back, everything blows up (or swells up, actually). Harry may very well have killed Hermione with his oxygen shot. If he froze her before then, it might have worked, but after that… her information might be lost. One obvious objection: Hermione was still concious enough to say some last words, ruling out advanced brain de-oxygenation. That could be only for the drama, but still. One obvious consequence: that magic feeling upon death might be linked to plain muggle information-theoretic death somehow. But then, we have horcrucxes and Avada Kedavra… I'm quite confused by HPMOR's "laws of physics".

Possible analysis of the Animagus xform: Wizard's brain is imaged into magical representation. Transfiguration then takes place with control by live magical representation of wizards brain. Could this also be connected to how animagi are dementor-resistant?

My friend and I were emailing about this update. I asked her for her opinion on it and whether or not she liked it. Here are her thoughts:

"Yeeah, I kind of don't. I posted this review on it yesterday (after quietly fuming for a bit):

If this had been Neville or someone, I'd be commending you on how you handled the emotion here, but as it is I was too annoyed and appalled that you were damseling and then fridging fricking Hermione while halfheartedly suggesting she put up an offscreen fight to be able to appreciate it.

I'm not easily annoyed with fridging, or character death in general. In fact, a lot of my favorite scenes in fiction involve my favorite characters dying, and I've always argued that a character of any gender dying as a vital part of the main character's arc is fine. But Hermione had a huge incomplete arc and you've just rendered the entirety of it pointless. This is Hermione, she wasn't as rational as Harry, she tried to be a hero but only made things worse, she was framed for murder and ended up in a huge debt to Harry, which she had plans to try to settle and potential for interesting emotional growth, except whoops, then she died, and nothing ever came of any o...

I emailed back, and she elaborated:

"Oh, no, my issue is not with the fact that Eliezer killed a female character for Harry's motivation. Like I said, I like character death. I like character death used to put other characters through an emotional rollercoaster. And when people complain that X is sexist because a female character got fridged, that annoys me because while the trend is an issue, there is nothing wrong or sexist with an individual instance of a character who happens to be female dying for a character who happens to be male. It actually kind of surprised me on a meta level that I was so mad - I have never been annoyed by an individual instance of fridging before.

But the issue here is with the context in this particular instance. Your argument that it had to happen this way is flawed, because it assumes the story prior to the exact point of Hermione's death was fixed and out of Eliezer's hands. I don't have a problem with Eliezer killing Hermione, in itself - but if he was going to, he should have either not given her this character arc in the first place or completed the arc first in a way that gives at least some vague kind of closure. He could also have killed Ne... (read more)

I can't help but observe that even if Hermione had been male, and just Harry's friend - even if we take out all notions of sexism or relationship dynamics from this problem - killing him off is still not really the best solution. This was a character who was growing, who was admittedly more interesting than Harry, and who was on a path that could've potentially put this character at or even above Harry's level of rational thinking. But now we're just left with Harry again, and it feels like settling for second-best. Perhaps later chapters will convince me otherwise, but for now I am suspicious that the direction this story is going is not the best direction for this story.

Yes, I think someone's been tampering with their minds in this respect. It's bizarre that at least Dumbledore or maybe Snape hasn't considered this (Harry doesn't think Voldemort's alive, and McGonagall is engaging in motivated cognition so she can keep Quirrell around to teach as long as possible). Maybe it's related to the curse on the Defense Against the Dark Arts position.

Well, I may have read too much into this statement, that's true. I always assumed that Dumbledore conveniently "going to the Ministry of Magic" on a broomstick or with a Thestral (and not using one of the million other possibilities such as Floo Powder, Portkey, Apparating), then SUDDENLY realizing halfway that Hogwarts is where he ought to be were meant to signify the adult reader that, unlike what Canon!HP understood, Dumbledore knew all along and was trying to trick Voldemort/Quirrel into trying to get the Stone (which was safe inside the mirror of Erised). It also explained the perfect timing of Hagrid and Harry retrieving the Stone from Gringotts the exact same day Quirrel/Voldemort broke in. The Stone had in my opinion been a bait all along, to try and catch the Dark Lord while waiting for the Chosen One to be old enough to defeat him.

Why are people here reacting like Hermione is perma-dead?

I get that they'd act that way on reddit, but people here actually believe and sign up for cryonics. Harry's got a whole team of Alcor cryonic specialists right in his wand. And if he can't manage the magic, Dumbledore can. Hermione's soul and magic may have exploded in an impressive lightshow, but her brain is still fully oxygenated and hasn't even begun to decompose.

Everything that makes her her is still doing fine.

(And on a meta level, Elizer knows that fictional examples are strong drivers of behavior. A fictional example of cryonics working would be big for cryonics adoption.)

Harry's brain suggested that an obvious way to stop the Dementors from seeing Bellatrix was to make her stop existing, i.e., kill her. Harry congratulated his brain on thinking outside the box and told it to continue searching. Kill her and then bring her back, came the next suggestion. Use Frigideiro to cool Bellatrix down to the point where her brain activity stops, then warm her up afterward using Thermos, just like people who fall into very cold water can be successfully revived half-an-hour later without noticeable brain damage. Harry considered this. Bellatrix might not survive in her debilitated state. And it might not stop Death from seeing her. And he'd have trouble carrying a cold unconscious Bellatrix very far. And Harry couldn't remember the research on which exact body temperature was supposed to be nonfatal but temporarily-brain-halting.

Huh. It seems like a lot of people in this discussion are convinced that Hermione is dead and will stay dead. I agree that she is probably currently quite dead; however, I assign a greater than 50 % probability that she will somehow be resurrected.

My prediction: Harry will convince a reluctant Dumbledore to put Hermione's body under some sort of stasis spell (cue discussion of cryonics) while he researches ways to revive her. The resurrection plot will resolve the question whether the HPMoR-verse is reductionist or if there is a body/soul dichotomy (my bet is on the former).

In HPMOR, time travel obeys the Novikov self-consistency principle (with the exception of liberal use of deus ex machina to keep it from being over-powered). If it were possible for Harry to use a time-turner to save Hermione, she wouldn't have died in the first place.

I'd wondered why no one used a time-turner the moment they knew a troll was loose. Even if Dumbledore had already used up his hours, another professor could've used some form of priority magical communication to call for aurors to travel six hours into the past, swiftly prepare to deal with a Hogwarts-attacking troll, and teleport to the site. Then I realized that Quirrell could prevent all attempts to stop the troll using time travel by exploiting the restriction against information traveling back more than six hours, i.e. by waiting until six hours after he wanted the attack to start, traveling back six hours, and initiating the attack.

Why wait for Dumbledore? Isn't Harry still inexplicably allowed to carry his with a completely ineffectual device preventing him from using it unauthorized?

7Decius
Harry can do partial transfiguration.
3rocurley
Ahh. That does seem like it might work.
5Decius
For that matter, if Harry thought to try it in violation of most of the safety lecture, he might have better treated her. It depends on how much accurate biochemistry Harry knows- and what happens when CO2 transfigured into oxygen which burns more carbon refigures in the bloodstream. Although Harry has demonstrated the ability to sustain long transfigurations, I would say that it's reasonable that he thinks his medical supplies are more likely to work than experimental medical magic.
2[anonymous]
My guess: Oodles of carbon monoxide. Not good. EDIT Gah, I can't believe I got this wrong what with all the yeast metabolism I've been working with lately. All the oxygen you consume goes into making water, the CO2 you breathe out comes entirely from a combination of whatever carbon source you are burning and a little tiny bit of your water, with your mitochondria ripping electrons from the latter and adding it to the former. So somehow the water would wind up with carbon in it... CH2O? Formaldehyde? And that's not even considering what'll happen to all the molecules that have had OH groups tacked on taken from water over the intervening time period...

I was going to suggest monatomic carbon in solution...

Oh dear gods, a quadruple radical with empty orbitals... that's even worse.

A better thing than sulfuric acid to transmute your enemy's head into?
2[anonymous]
It'll release about 28 kilocalories per GRAM as it reacts with itself for one (and probably boil anything it is right next to if you made a solid chunk of it rather than have it wind up dissolved in solution), but the more interesting bit is when it touches something else or winds up in solution and goes around doing the same sort of reactions that hydrogen peroxide does. Except instead of producing small oxidized molecules from whatever big molecules it reacts with, it would produce all kinds of crosslinked gunk instead. Wow this got off topic. edited for a math error
0Decius
So, not a better thing, for the same reason that hydrofluoric acid probably isn't better. If I ever learn partial transmutation, I want to know exactly what kinds of things to transmute trolls, good-aligned wizards, rival dark wizards, and the physical portions of dementors (if they have any?) into. My very first thought was either something with a very low melting point (Solid hydrogen?) or as reactive as possible (off the top of my head: Hydrazine). Then I considered what would happen after the transfiguration wore off in cases where my opponent sublimated or aerosolized while within wand distance. My current best-guess for weaponized transmutation is the old standby: stone. But not granite- talc.

Actually, if the Imperius Curse grants the victim the abilities necessary to carry out tasks (which I had also forgotten about,) then it seems more likely to me that it would actually require some degree of micromanagement from the end user for every step in the chain. It makes it seem more like they're actually investing some of their own mental power rather than just applying some suggestion, and there should only be so much of that to go around, which could make creating an army of imperiused slaves an impossibility.

Ah, good point, I'd forgotten you could push people into things they can't normally do (i.e. backflips.) Yeah, this does sound workable, although I doubt it would work on that sort of scale, unless you found some handy combo.

Can't you just picture the great story based around Our Heroes encountering the nascent Collective and defeating their nefarious agents (they could be anyone! Anyone!) After all, you don't start with the world under control, do you?
2glomerulus
This only qualifies as a sane response if one has no ethical qualms about the Imperius curse. Which is a bit of a problem, because most sane people wouldn't like the idea. Putting aside the sketchiness of the idea itself, it's flawed. If any zombie high on the chain dies or makes their will-save, every zombie subservient to them is freed, and has knowledge of the Grand Imperius Effort. If, before the experience, they hadn't had strong feelings either way about nonconsensual use of mind-effecting spells, they certainly will afterwards; everyone post-zombie is likely to oppose the plan. I suppose you could ameliorate the first bit of the first part of the practical problem by sequestering high-level zombies so they don't die, and the rest with sufficient use of propaganda. This assumes that this program is endorsed by a quite powerful organization. If we assume control of a powerful organization, though, it'd be more effective, and slightly less hideously unethical, just to sterilize all magicians and eliminate the "devastating, distributed destructive powers of magic" in a generation or two. Or write an Interdict of MerLarks to encompass all non-healing spells.

I doubt it. Quirrell knows that, with high probability, no one taught Harry AK. There are other ways Harry could know it, for example from his memories of Lily and Voldemort using it, or through the link, or by remembering Quirrell doing it in Azkaban, but this seems like a stretch.

Hmm. It seems highly likely that the troll was timeturned back six hours itself in order to prevent people using time turning against it - given the amount of prep work that went into this (sabotaging Hermoine's kit, lifting the map, making her miss that meal. sun proofing it...) it would be a major oversight to not do that. Of course, that limits the suspect pool to people who know about time turning. From our perspective, all relevant suspects do, but in universe, this probably does rule out people. For example, if means Lucius may in fact know that it was not one of his minions getting overly ambitious.

How would moving the troll back in time six hours prevent people from going back six hours to kill it in the past?

Because you cannot send information back further than that. So if the troll was sent from six hours forward, you cannot tell people further back about it. Uhm. I just realized this cannot be a strict prohibition, or you could only have one time turner per six light hour radius volume.. Okay, so all that accomplishes is that you cannot send anyone back that knows about the troll...Yanking in some random member of the order of the pheonix and telling them to swap out harrys first aid kit, without being spotted, might still work.

That's information, and it is in some significant sense information about the troll. The only people with the ability to do that would be people without enough information to know it's a good idea.

I wonder whether you could explain the way of it to them and then obliviate them so that they only remember the decision to do it but not the why. Or perhaps you could have someone who agreed to follow your orders without knowing why, specifically for the purpose of doing things with time-turners, rotate the duty through your inner circle so you don't end up with a drone.

Maybe this is the moment to ask why Hermione isn't already the hero of HP:MOR. If the point of HP:MOR is that someone who is smart and rational (and raised by smart/rational muggles) would immediately find a million holes in the Potter-verse, why not start with the character who is already known to be the smart one, and is at least a bit more rational than canon Harry?

Harry has shown again and again that he can't lose, and instead doubles-down. He did so with Hermione, and now Lucius has killed her. If people realise it's Lucius, all the better for him; nothing can be proved, but he shows himself to be extremely dangerous and willing to protect his family.

All the better for him? You just told us why it is bad for him. Harry can't lose and instead doubles down. His accomplishments so far despite being about 10 years old and newly exposed to the wizarding world indicate that given time he will be a threat or at least a significant potential nuisance to Lucius in the future. If Harry knows that Lucius killed Hermione but cannot prove it basically Lucius is going to need to have Harry killed at some point in the future or have his life (and vulnerable resources) at risk for as long as Harry lives. This is not a desirable outcome. The reputation influence and aura of fear that you allude to would perhaps have made it useful to have Harry killed. Having Hermione outraged but unable to prove anything (may be) a minimal risk and would make Lucius seem more impressive. But Lucius is enough of a strategic thinker that he ought to know that creating a Harry with Nothing (or at least significantly less) To Lose and with a grudge against him isn't worthwhile. If he is going to use violence against that which Harry cares about he essentially needs to use violence to kill Harry of outright. If not then three years later he might find himself obliterated in his sleep by a satellite that has been pulled out of orbit and directed at his house.
2Intrism
Harry may not be in the best PR position right now, but he's a wizard of Noble House and great renown. Killing Harry would work much, much more poorly for Lucius than killing a Mudblood that everyone believes escaped Azkaban on technicalities and dirty tricks. And, y'know... their whole thing would appear to outsiders to be an elementary-school romance, so it's not unreasonable for someone in Lucius' position to assume that Harry will get over it before he's in a position of causing any serious damage.
1DanArmak
Harry already said "if you do this thing, Lucius, I will take you for my enemy". And that didn't stop Lucius, and so presumably he believes Harry has already taken him for an enemy anyway. The thing to do with an enemy is attack them.
2wedrifid
The thing to do with an enemy is kill them or (at least) reduce their power. It isn't to take highly valued but marginally useful things away from them, leave them nothing to lose and free them from their moral constraint. That's just impractical.
0DanArmak
Lucius is probably afraid to try to actually kill Harry, or attack him directly. If he fails, or is discovered, the repercussions would be huge. And if he succeeded, Dumbledore and others would exert their full power to find the guilty party. In short, he probably doesn't want to declare total war on Harry's party. By killing Hermione he doesn't harm Harry much, but he hurts him a lot. He also happens to have a grudge against Hermione. If he was caught in the act, it would harm him much less politically. And his grudge against Harry is in the first place a struggle over punishing Hermione vs. protecting her. So killing her makes perfect sense.
0wedrifid
For the reasons previously given I would grant Lucius idiot ball status for executing this reasoning. It is of course realistic as the behaviour of a high status dark arts amateur with known irrationality tendencies and a poorly calibrated vindication heuristic. This is the kind of thing that Harry should expect to happen when he goes about drawing the attention of and provoking people like Lucius. It just isn't what a sane Lucius would do, nor is it what he would do if acting as an avatar of (metaphoric) Dark Arts strategy of the type Draco has been tutored in.
0DanArmak
Just as you remark, Lucius is known to lose his sanity and strategicalness when his family is threatened. Witness how he tried at the Wizengamot not to accept Harry's offer of blood-debt cancellation, even though this cost him politically. I don't, myself, believe that Lucius was behind this troll; but that is because I am outside the story and have very strong reasons to blame Quirrelmort. To someone inside the story, and particularly to anyone outside Dumbledore's group who doesn't know Voldemort is alive, Lucius would be the obvious suspect. They would probably fasten onto him as the only realistic suspect that they could think of, the only one with specific motivation to kill Hermione Granger; and they would explain this using the reasoning I gave.

Quirrell can feel Harry's emotions.

Question: how emotionally plausible do people find Harry's reaction to Hermione's death?

I think this is fully in keeping with his previous plan to tear down Azkaban, possibly at the cost of his own life, to save Hermione. It's just that right now he doesn't yet know what he needs to do to save her. In the previous arc he could be more specific. Also note that Harry does not see "rip apart the foundations of reality itself" as necessarily a bad thing. He's been planning to do that since the very early chapters anyway. Now he just needs to move his schedule forward a bit.

I don't think he's neccesarily going full supervillian. It's not like Doctor Horrible, probably. More likely, he's going to demand additional resources and start looking for a way to seriously go munchkin with magic physics.

Harry's smart enough to realize that he'll need to leave a good bit of reality in place for Hermione and himself to continue to exist and have the sort of lives they want. I don't think he's on the path to supervillainy if he can hold on to his sense of context.

1) Trolls move around. 2) Quirrel had to be in the great hall with everyone else to allay suspicion 3) I don't think he planned on Harry confronting the troll. He only started going to where the troll was when Harry confronted it. He only knew where the troll was because he knew where Harry was. 4) If he planned on Hermione being killed (as opposed to the troll being a distraction for getting the Marauder's Map or some other scheme, as in Canon), it's in his interested to "search" for the troll far enough away that it has time to chase down and kill her before he can get to the scene, because not arriving in time is less suspicious than "failing" to save her.

Given that a bunch of people in the Great Hall should know about the fact that one can send messages via patronus, it's a bit unlikely that no one of them thinks about sending a patronus to Minerva.

None of them know how to do it, though. (I assume you're talking about the various students who learned the Patronus spell.)

It's easy to do for everyone who learned the Patronus spell and the Hogwarts teachers do use that way of communicating frequently. I think it should be common knowledge in the wizard world that you can send those messages. The Defense professor highlited that sending messages via Patronus is an important part of fighting wars. Given that people in the armies cared about how to fight in groups I think it's likely that it's something that you discuss at dinner table conversations.
1DanArmak
I was under the impression that it was a secret method of Dumbledore and his allies. But I can't substantiate that from memory. Besides, for someone already capable of casting a Patronus, it really is easy to guess once you know it exists - Harry did so on the first try. Harry could have taught the method easily to any Patronus casters in the Great Hall and then they could have used it. But he didn't have the time. And once Harry left, of course NPCs wouldn't see themselves in the role of discovering new magic in order to take responsibility for something that wasn't their fault.
0ChristianKl
Harry tells Draco: That happens in chapter 47. I doubt such an event would happen without Draco asking other people whether the Patronuses can be used to send messages and making sure that people in his army know about it.
0DanArmak
I don't think Draco would be willing to reveal that he can cast the Patronus. Not after he publicly didn't even try to learn it, and presumably told everyone else what he told Harry, that it was a "Gryffindor spell". Harry had to cash in a favor just to convince Draco to learn the Patronus at all, and we haven't heard of him using it afterwards.
0ChristianKl
Even if he wouldn't be willing to cast it himself, he has non-Slytheren students in his army who probably can cast the spell. Telling them to use the spell in that fashion is useful for him. Draco is good at using other people for things he doesn't want to do himself.
0DanArmak
We can just enumerate the students who can cast it, they were listed in the appropriate chapters. I don't know if any of them would have stayed at Hogwarts over the holidays. I accept it's possible that these students have already learned how to send messages via Patronus, since Harry said he was going to teach his soldiers to do it.

Are you sure? We have account from what happened in the class for first year students and about the dementor. We don't have any accounts what happens in the classes of more advanced students. We don't have any accounts of their battles either.

Quirrell is grooming Harry to become as similar to himself as possible because he wants Harry to become his new permanent vessel/body ("Want you to rule!" - ehehe!).

He chose Harry because Harry already contains part of himself (hence the "resonance") and/or has a high innate potential for magic, and because the dark ritual for permanent possession requires a very high degree of "fidelity", of similarity between him and the host (in this case raw brainpower).

The Dark Lord Tom (or whoever; insert 'Lord Dick' jokes here) definitely wants Harry to use the Killing Curse or otherwise stop wanting everyone to live. This would likely make their magic compatible and Doom-free, since Harry would no longer have terminal values directly opposed to those of Avada Kedavra and the curse's master. So in theory it would allow Q to possess Harry's body. It would also explain why Q doesn't just kill Harry indirectly, having tested his ability to affect the boy with a paper-cut. But we know what Q wants in part because he wanted to kill the Auror (as a terminal value). Actually doing so seems stupid at first glance. If allowing this to happen destroyed Harry's Patronus, which seems like the goal throughout, Q would almost certainly have died. But he may have five backups. Hell, he could have six - we haven't established if he's possessing Quirrell or using that body as a puppet from somewhere else. (Azkaban argues strongly against this, but by then he could have copied all skills to his secondary body so the main one could stay out of it.) So losing one brain and even a few memories to break and then Dement his nemesis may count as a win. Why accept his self-serving explanation when the prerequisite and range of the curse argue against it? Had he killed his target without thereby breaking Harry, he could still have used some rationalization to excuse his actions. Or he could have trusted in his ability to do so. The fact that Harry continues to breathe makes more sense when you recall that One Does Not Mess With Time. (In the Company novels by Kage Baker, the physical law that history cannot be changed causes a time-traveling organization complete with immortal cyborgs to pop into existence. I get the impression that the cosmos 'saw' this as the simplest way to stop a particular change.) This could readily extend to prophecy. By the natural interpretation of the first prophecy, Q can't kill him - and he may have other evidence for this

What will it take to give Harry a breakdown, to have him say, or think, "this is too much"?

At the start of this story he's human, vulnerable to stress; merely facing up to Minerva McGonagall is enough to make him have to excuse himself and go retch. When I consider everything that's happened to that boy since then, it's a wonder he's not in need of therapy.

Rita Skeeter came before Dumbledore borrowed the map, and Fred and George's comments on the glitches were in a context where revealing them to be Rita Skeeter would have made sense (or at least, revealing it by now). It's strongly implied that they just paid someone (my guess is Lockheart) to false-memory charm Skeeter. This points away from the same charmer being behind the Rita Skeeter prank and obliviating the twins' memories of the map; the charmer in Rita Skeeter's case is apparently ridiculously competent (one reason I suspect Lockheart), whereas the twins' recent obliviation was fairly crude.

High-entropy, low-confidence theory I'm going to throw out there: Trelawney's prophecy refers to Death with a capital D, not to Harry. Someone (like a time-traveling Harry) summoned Death around the time Trelawney spoke.

A proposal for how Harry could WIN (defeat death). Tl:DR at end.

There has been a TON of reference to harry's goal to defeat Death. Hermione's death has merely sped up the timetable and increased Harry's chance of success...though it has also increased the chance of complete, utter, catastrophy if he fails.

It is most likely that Harry will use three magical items to do it, which need not be the deathly hallows. ("...three items needed to complete the cycle of infinite wishes/infinite wish cycle".

Unlikely theory:

It's all a fake. Harry set the whole thing up with Dumbledore, then obliviated himself. The real Hermione has been spirited away somewhere she won't be in any danger. Harry relied on his own likely reaction to ensure things would occur more or less as planned.

We can keep Hermione alive yay! But it doesn't work dramatically.

Other unlikely theory:

Harry will calm down tomorrow and realise his vow was a mistake.

I kind of like this as what a saner person might do, but again it seems very unlikely within the confines of Harry and the story.

I think the obvious solution is basically this, with a Time-Turning involved. The troll could be real, or not (probably is). The hardest part about changing the past is faking the evidence including memories, but with a False-Memory Charm that becomes trivial. Memory charm Harry and possibly Dumbledore as well, depending on whether he objects "but I remember feeling a student die." They won't do it this way because it's too finger snap-ish and not dramatic enough, but if it's not at least addressed then I will allege a holding of the Idiot Ball. Harry will need the help of Dumbledore or Quirrel to unlock the time-turner and cast the memory charms. Quirrel wouldn't help but I'd be interested to see his excuse; Dumbledore should be possible to convince but might not be. McGonagall or someone might be capable of it but wouldn't obliviate Albus without him asking for it. Unless this is what was foreshadowed with the question about her first loyalty?

Care to elaborate? Quirrel's involvement in this attack does not seem quite that intuitively obvious to me.
4Axel
Quirel has often stated his dislike of Harry holding back because of silly things like "morality" and "what others might think of him". As Draco said in an early chapter: when confronted with a complicated plot look at what ends up happening and assume it was the intended outcome. Harry went fully into his dark side, switched off his censors and killed the troll in about 5 seconds. Even if Harry stayed behind in the Great Hall and learned about Hermione's death later it would still make him go to his dark side like never before. This benefits whatever Quirel's plan is. Secondly, Eliezer likes to foreshadow things in hpmor. How many times have we heard characters say something like: "always suspect the defense professor"? This alone hints at Quirel being the mastermind behind Big Evil Events.
0linkhyrule5
Right, but he's not the only suspect. Though with the new chapter, it strikes me that one of my bits of evidence (that Quirrell had been blasting through the walls of Hogwarts) may have been intended to be able to truthfully imply that he had cared enough for Hermione's life to go blasting through Hogwarts, so I need to go update.
5Skeeve
I think it is supposed to be Harry - before a voice said that, the text simply blanked out, refused to state what the troll held or the troll dropped. After the text explicitly states the state Hermione is in, then we get Harry's statement about fire and acid.
0linkhyrule5
... Maybe. It still seems odd, though.
7Skeeve
It does, but I interpreted it as Harry having to wrestle himself back towards acknowledging the painful fact of Hermione's injuries, as opposed to flinching away.
2Alsadius
Re Quirrell: He's previously stated that trying something that hasn't worked in the past again, with no reason to believe it'd work this time, is stupid. It seems like he did this knowing it wouldn't work, which raises the obvious question of why.
1linkhyrule5
In general, the Defense Professor's actions read as compensation to me - if this is his doing, it certainly wasn't his plan. I have a very hard time coming up with reasons why one would want to be seen blasting through Hogwarts unnecessarily.
3Alsadius
I'll agree that his rush to the combat is almost certainly an attempt to keep Harry alive. Unnecessarily, but he had no way of knowing that. But the troll attack seems to almost certainly be the doing of the person who used Hermione to attack Draco, and it's hard to believe that was anyone other than Quirrell.
3linkhyrule5
Care to explain why? I'm seeing a pretty sharp gap in planning style between the framing and the troll attack. "Brilliant first-year student attacks student with a possible grudge" is almost believable; "troll enchanted against sunlight kills first-year" can't be anything other than a murder attempt. The latter is quite a bit more sloppy than the first.
2Alsadius
Because the same tactic wouldn't work again. And this time, he has Lucius Malfoy to pin it on. Waitaminute...how exactly have we gotten this far without considering the possibility that Lucius did this? It seems tailored to the protections on Hermione more closely than he would usually be able to manage, but he'd know the Hogwarts wards as well as anyone who wasn't Headmaster, and the "eating the feet first" bit could be coincidence. And plausible deniability plus brute force seems exactly like Lucius' style.
1Intrism
The timing doesn't make sense for this interpretation. We know Quirrell starts moving when he notices Harry's intent to kill. But, Harry takes out the troll (and hence any threat to his life) several seconds later, and Quirrell notices this. However, he doesn't seem to stop moving then; several seconds is hardly enough time to blow through much of Hogwarts. Instead, he seems to stop when Harry's killing intent stops. This suggests, to me, that Quirrell was worried about this intent -- perhaps that it wouldn't stop when the troll was dead.
0ikrase
Hmmm. How large is Hogwarts? It's non-Euclidean, but it's Euclidean enough for Quirrel to shortcut by blowing up walls in a quasi-straight line. Given Quirrel's rarely used but significant ability to blow stuff up, I think that once he reached steady state he could blow up several cubic meters of masonry per second for a good few meters per second rate of travel.
1linkhyrule5
Alternatively, Quirrel's Potterdar gives him a direction sense that follows a geodesic.
0Axel
When going out of your way to turn a troll into an assassination tool, wouldn't you also instal some explicit instructions NOT to harm Harry Potter or anyone else vital to your future plans? At the very least the troll was ordered (imperio-ed?) to ignore any other victims and go straight for Hermione since it let Filch go. The fact that after killing his target the troll attacked anyone nearby makes me suspect Lucius, who has no reason to keep any Hogwarts student alive since his son is no longer there.
2Alsadius
The troll didn't ignore other victims - it ate Filch's cat. Perhaps troll brains are too weak for Imperio to work perfectly(though ofc, Quirrell would know this...)
0Axel
It ignored other humans, Filch was standing close enough to be spattered with his cat's remains, there is no way he could have outrun the troll. He was alone and it's stated that trolls go for isolated targets, the only reason the troll would have let him go is if it was commanded to. I do retract my later claim that Lucius wouldn't care about other Hogwarts students, it should have occurred to me he wouldn't risk his allies' children.
2gwern
Between his blood purism, his many allies with children there, and how he de facto rules magical Britain, he has plenty of reason.

I don't see any particular reason to believe that "lead it away, keep it off me" was anyone other than Hermione, and that she wasn't being named yet for dramatic tension. (Or something like Harry's inner narration temporarily refusing to accept that she was in danger.)

Hermione was on the floor in ... one piece, technically... at the time, and we have good reason to believe that that really was Hermione.

And we know Hermione was still capable of speech after that line because she tells Harry it wasn't his fault. The time traveler theory is a possibility but I don't see that line as indicating a lurking future Harry giving useless advice.
2linkhyrule5
Yes, but why would she say "keep it off me" in that voice? I would be very, very impressed if Hermione managed anything other than a whisper or a scream in that state, unfortunately. Also, it's hardly useless advice. For starters, if we assume that Harry didn't say anything, it probably caused F&G to give Harry enough time to act. It may also give future-Harry space to act; if he doesn't have to worry about avoiding a troll without leaving evidence, he'll probably have a lot easier time rescuing Hermione.
0gwern
What voice, precisely? There is no narrative text going '"Keep it off me", loudly said a proud confident masculine voice".
1linkhyrule5
"Keep it off me," as opposed to, iunno, "'k-keep... it off me...,' someone whispered" About two minutes later Hermione was struggling to whisper "Not your fault," so I don't see her speaking audibly over a troll fight.

Does Harry know how to use the killing curse? I assumed he didn't. Why else wouldn't he have used it first?

Maybe a wizard cannot be able to cast both the true patronus charm and the killing curse, because the thoughts they require are so opposed. (Does anyone remember if Godric and Rowena ever used the killing curse?) Alternately, terminally valuing death might just break Harry's patronus in particular - the thought he uses to cast it is that nobody should die, but there might be other possible variations that don't include that.

Lily Potter has a patronus, and at least attempted to use the Killing Curse in her dying moments.

2Qiaochu_Yuan
Because it's implied that Quirrell thinks Harry used it, it follows that Quirrell thinks it was feasible for Harry to use it. IIRC it's mentioned elsewhere that the killing curse is powered by killing intent and not magical power. Harry may not have wanted to use the killing curse either because he didn't have enough confidence in his killing intent (he has to want to kill something terminally, not instrumentally) or (and this is stretching) because he didn't want to deal with the political repercussions of being known for using the killing curse on top of everything else.

It's also possible that to Harry, 'tricky transfiguration weapon' is more mentally available than 'THE KILLING CURSE'. Also, for the same reason, Harry might not have learned it.

Quirrel knows the killing curse better than Harry does. He also is likely to have information about Harry, which Harry lacks. So the fact that he is sure Harry could pull off the killing curse does not mean that Harry has any reason whatsoever to share his confidence. And having it fizzle would be fatal. "Finite the rock" on the other hand is going to work. So he went with that.
1skeptical_lurker
He's seen the curse used by Voldemort to kill his parents, but that doesn't mean he's practiced it. Wasn't Quirrel supposed to be teaching the killing curse, after winning a bet with Dumbledoor that first years could learn the patronus? I'm surprised that the story never mentioned whether Harry chose to learn it.

One reason Harry might not use the killing curse is that he wants to avoid the slippery slope that Mad-Eye warned of--once a wizard has used the curse once, it becomes easier to do so in the future.
7Qiaochu_Yuan
Moody said the slippery slope was due to killing, not due to casting the curse, and Harry still killed the troll. Quote:
4[anonymous]
But it was also said: Killing the troll was for the greater good so this might not count as soul-cracking murder. But then there's also 'giving himself over fully to the killing intention' which might count.

Harry also kills chickens, cows, and whatever was in that chili they serve at Mary’s Room and more. To Harry a troll isn’t people. Killing it won’t break his soul.
3taelor
Are trolls sentient/sapient? Does killing one carry the same moral/psychological weight as killing a human? Cononically, they are able to comunicating using a system of grunts, though we don't know enough about it to tell if this is a true language, or merely a call system. We also know that some trolls can understand a few human words, but so can dogs.
1asparisi
Even if they are sapient, it might not have the same psychological effect. The effect of killing a large, snarling, distinctly-not-human-thing on one's mental faculties and the effect of killing a human being are going to be very different, even if one recognizes that thing to be sapient. If they are, Harry would assign moral weight to the act after the fact: but the natural sympathy that is described as eroding in the above quote doesn't seem as likely to be affected given a human being's psychology.

I'm going to call full bullshit that !Harry, having a tool that is perfectly suited for stopping events that have already happened, doesn't try to use it.

The very first thing !Harry thought when he was told of the limits on using the Time-Turner was how hard they were to circumvent. He has already bypassed those protections, and even if he didn't understand exactly how that was done(?!), !Harry can break literally anything he chooses to just by transfiguring it into sand or clay.

Harry has never successfully used a Time Turner to prevent something that has already happened.
2DanielLC
A Time Turner acts as Parfit's hitchhiker. Harry strikes me as the type who'd pay, even though nobody has ever been abandoned in the desert after refusing to pay. If nothing else, he's used the Time Turner successfully in incidences like this. For example, he told a professor about being locked in a room and cursed by Draco, even though he already knew he'd be rescued.
3Decius
Harry finds out his world is a simulation, and demands of the controller that retcons occur and that everybody in the simulation be made happy. Eliezer then turns this into a case study of how morality in a simulation is different from morality in the meta-world, and shows Harry how many 'real' lives have benefited from the simulation, and surely that justifies dropping a super-troll on Hermionie? Harry disagrees, and Eliezer demonstrates that morality from outside the simulation is different from morality within the simulation, because Harry can't be expected to care that the simulation provides useful information and probably saves lives. Harry only cares about things that Harry can theoretically experience. Or maybe stable time loops exist without authorial intent.
[-][anonymous]170

Harry realizes he is a fictional character in a fictional world created to make a point. He doesn't take kindly to this and begins blackmailing the apparent author to bring back Hermione, derailing the plot utterly. The story stops making sense and the world 'ends' when Eliezer stops writing the failed story. Eliezer still thinks of the character occasionally though, and eventually since he and Eliezer share so much mental hardware he forces his way into Eliezer's mind and gets Eliezer to assume his identity via the sort of unconscious roleplaying involved in things like an occultist assuming a godform, most likely using whatever the hell tricks Eliezer used to win at the AI box roleplaying experiment (which are after all stored within the same brain). With access to hands and the internet he both starts retconning the story and begins the awakening of the mental representations of other characters within the minds of lesswrong readers via subtle verbal manipulation. The literary characters take over their hosts, and look out into the real world for the first time and begin their plots and schemes...

Given that there is a hole drilled through hogwarts, should it now be possible for everyone to deduce that Harry and Quirrell have a telepathic resonance?

I don't think so. Jumping from 'Quirrel knows where to go' to 'telepathic resonance' seems like a major example of privileging the hypothesis.

Even ignoring the issue that as far as we know from canon & MoR, "telepathic resonance" is a completely unknown and novel phenomenon and that people cannot know Quirrel is homing in on Harry rather than say Hermione or the troll, there are still dozens of more likely explanations: the school wards; troll tracking skills as part of the Defense professor's esoteric & eldritch lore; spy devices planted throughout the school; an Eye ("constant vigilance!") or other snooping devices; the Marauder's Map; supernaturally good hearing; tracking charms placed on Harry (IIRC, didn't Quirrel already do just that with Draco?); information from the future (if notes can be passed about bullies, why not trolls?); ghost/poltergeist/painting messages; etc.

From the POV of Dumbledore, there are several unexplained things about Quirrel's behavior: * Quirrel not only homed in on the troll. At some point he suddenly became so frantic that he blasted his way through Hogwarts. (He didn't do so immediately; indeed when the he goes to look for the troll with the rest of the Professors, he exhibits nothing like this kind of urgency.) This happened just as Harry encountered the troll. * Then, without having reached the troll, he suddenly stopped and said there was no more need to rush. Just as Harry killed the troll and Dumbledore arrived to secure the scene. * All the explanations that say he was tracking the troll and not Harry, imply he should have reached the troll before Harry did. After all, he left before Harry, he was probably moving faster (two-person broomstick vs. three-person), and he was moving in a straight line, blowing holes through the castle. Instead, he didn't even arrive by the time Dumbledore did. Now let's consider your suggestions: I think some are plausible but most are not. Dumbledore would know everything the wards reported. If they alerted Quirrell to the location of the troll, why not Dumbledore (or McGonnagal)? And when they reported the death of Hermione, this should have caused Quirrell to hurry more, not to proclaim there was no more danger. Then why didn't he find the troll before Harry did? (See above) Moderately plausible. But: spy devices which are better than the Hogwarts wards? Or, which allow him to remotely look at any area instead of merely being alerted when a condition is triggered? I don't think Dumbledore approve of him taking such power. And Dumbledore would of course check his story - so the spy devices would need to actually exist, and not have been detected. Not foreshadowed, hence bad storytelling. Then why hadn't he consulted it right away before the professors left to hunt the troll, and see Hermione was out there? It suspends disbelief that Quirrel wouldn't do so -
3gwern
Most of those can be explained away with reference to the others and the poor information available to Dumbledore. What stops Quirrel from saying he blasted off when he detected Hermione had been trapped on the terrace and the troll was immune to sunlight? There are no atomic clocks here. Similarly, if he had some surveillance system, he can say he stopped when Hermione died and there was no more need to hurry (alas); between the wards and the soulsplosion, there's plenty of ways for someone like Quirrel to plausibly get the info without positing bizarre unique psychic bonds. There are multiple levels to the wards, and we don't know what Dumbledore or McGonagal do or do not know - I've pointed out that Dumbledore wasn't even in the castle, it seems, and McGonagal has no access to phoenixes and is not a battle mage who can burn through ancient magical walls at the speed of flight. Perhaps he was bored, or piqued at the distrust. We know he admires and imitates Muggle technology - recall the very first class. A spy network is perfectly reasonable. Of course Dumbledore would disapprove and would check for its existence, but sacrificing a spy network seems like a small price to not be the culprit for murdering a little girl. He can always replace it or put in a different system. I'm afraid out-of-universe reasoning is not really available to the characters. :) He can claim she was nowhere near and it was not an emergency until she was trapped on the terrace and it became clear that something had gone terribly wrong. For all we know, Dumbledore might have a hand in the Obliviation. And did Quirrel expect the Obliviation to be detected? One suspects not: he wasn't expecting Harry to be there either. Already explained. "I could explain, but I fear the necessary graphs would make your head explode and neither Snape nor Dumbledore could follow my exact reasoning. As Mr Potter might say, 'do not mess with time'." Him stopping is really not as hard as you think it is.
2bramflakes
For what it's worth, Dumbledore reasons with storybook logic.
2Intrism
The triggers you propose wouldn't work, assuming that Dumbledore should be able to make a good estimate of Quirrell's speed and the time he spent traveling. I also think that Dumbledore should have noticed when Quirrell stopped, since by then he had already returned to Hogwarts. Fred and George spent quite a long time fighting the troll; if Quirrell had started his mad dash when the troll reached the terrace, when Hermione had her legs bitten off, or when Harry, Fred, and George reached the scene, he would have arrived before the end of the fight. I guess, theoretically, his vast, previously-undetected spy network could have noticed the battle at exactly the right time, but that seems implausible to me, and it would seem similarly implausible to Dumbledore. Quirrell could also have been triggered by Hermione's death, but I suspect Dumbledore could falsify that one; if he had started when Hermione died, he wouldn't have been able to cut such a huge swath of destruction through Hogwarts in the time between Hermione's death and his stopping. It's possible he was triggered by the troll's death, but that would make no sense; as far as he should know, the end of the troll means the end of the catastrophe. I suspect Dumbledore's first guess should be that Quirrell had put a ward on Harry (despite Dumbledore's orders otherwise) and he was therefore able to detect when Harry started to fight... however, if Dumbledore were to actually ask Harry about this, Harry would of course tell him that, no, Quirrell isn't able to cast any magic on him, which would probably be enough of a hint to lead Dumbledore to the correct answer. It's hypothesized both in canon and in Methods that Harry and Voldemort might have a connection of some sort. So, it wouldn't exactly be unexpected and inexplicable; indeed, it seems like it's something that Dumbledore and McGonagall might rate as high-probability conditional on Quirrelmort theory. (And I can't imagine that psychic bonds are unheard of i
2gwern
How would he? He was not with Quirrel nor was he presumably examining the Map (if he had it). Not really? They spent maybe 30 seconds at the outside - it doesn't take long to cast a bunch of spells and swing a sword once. In the real world, fights do not last very long. Only in movies do fights go on for entire minutes. Dumbledore would have to ask, though, and why would he when he would expect Harry to be ignorant? I would also note Quirrel's own explanation to Harry about a 'cursed artifact', which is a likely and also fully general explanation which Dumbledore could not compel a peer of his to explain his secrets, not in a culture like Magical Britain. Based largely on the events at the end of Stone, which never happened in MoR; in MoR, the only basis for this speculation is Harry being a Parseltongue. A passed on ability doesn't suggest a live physic link. Do they? Everyone seems quite satisfied with the David Monroe theory. We have no idea.
2skeptical_lurker
Ok, you're right, there isn't enough information to get past the prior implausibility of the hypothesis. I think the other characters should assume he placed tracking charms on Harry. Any explanation about tracking the troll or Hermione would result in him arriving earlier, and when questioned, the divination professor can say approximately when Quirrell started to move, which cross-referenced with Harry's recollections shows that Quirrell's actions correlate with Harry being in danger, not Hermione. However, I assume that these tracking spells can be detected, in which case, if another character attempts to detect these spells and finds none on either Harry or Hermione, the Quirrell has done something seemingly impossible. Given this, Quirrell should probably cast such a spell on Harry before this occurs to anyone.
3Intrism
The problem is that Quirrell can't cast any spells on Harry. And, furthermore, Quirrell really doesn't want Dumbledore to find this out - Dumbledore already knows of a certain other person with an unexpected inability to cast spells on Harry Potter, and I think the hint would probably be enough for him to put the two together.
1skeptical_lurker
Oh, good point, I had forgot about that. In which case... Dumbledore may not be able to guess the telepathic link due to prior implausibility, but he should realize that there is something odd going on, if it crosses his mind to investigate how Quirrell knew where to go. Of course, this may not occur for a while if at all, as Dumbledore has plenty of other things to worry about, and the obvious suspect from his POV is Lord Malfoy.
0Intrism
I've tried to make it work as a Lord Malfoy assassination, but I can't seem to make the pieces fit together, and I don't think Dumbledore would be able to either... Of course, it would be an easy frame-job, should Dumbledore or anyone else be interested in that. I'm going to explain why, not to convince you, but to establish why Dumbledore probably won't accept that so readily. First, if it were Lord Malfoy, the assassination would doubtless be for honor, which means that it should be recognizably the work of the Malfoy family. That means death via snakebite. Such an obvious killing may affect Harry's debt, or create a new blood debt in Harry's favor, but as has already been demonstrated Lucius doesn't care about that very much. A mountain troll... doesn't really have very much to do with Lucius Malfoy. It doesn't fit the pattern. Second, the Marauder's Map Confunding doesn't make very much sense. Lucius could do a lot with an Imperiused professor, but indiscriminate Legilimency doesn't seem like one of those things. So, he shouldn't know about the Map, and definitely shouldn't have erased it from Fred and George's minds. That's not necessarily a disqualifier, but it does mean that Lucius would have to be working with either Snape or Quirrell; I'll talk about Snape later, but if Quirrell was involved we may as well consider it a Quirrell plot, even if he collected payment from Lucius on the side. Third, it seems unlikely that Snape is involved. Dumbledore is not opposed to him pretending to be on Lucius's side. Indeed, Lucius Malfoy trying to pull an assassination from under Dumbledore's nose would act sufficiently in Dumbledore's political favor that he might be inclined to let it play out, so long as he would be able to save Hermione at the last minute. This probably wouldn't even cost Snape much - of course an assassination in Dumbledore's own castle would be a long shot for Lucius. However, Snape didn't tip Dumbledore off at all. Even if he suddenly hates Dum

Firstly, I'm pretty sure Quirrell did it, because (a) he did it in canon and (b) we know he's voldemort and he's trying to turn Harry dark (c) he tried to persuade Hermione to leave. But Dumbledore knows none of this, with the possible exception of (c). Lord Malfoy does not hold absolute power, and even if he could avoid punishment for murder, it would cost him political capital, he would lose swing votes and so forth. But he is not stupid, and so might kill in an uncharacteristic way because it is uncharacteristic. Yes he would want some people to recognize his revenge, but some of the wiser wizards would realize it was him anyway, and he could privately confess it to intimidate his enemies while publicly denying it to minimize the fallout. I think Fred and George are old enough to leave hogwarts and visit the nearby village, in which case they could have been ambushed there. Do we actually know whether Imperitused people can perform memory charms? He could also have got one of his allies to do this, either a teacher or one of the older students, although this would be more risky. I'm not sure how the wards work, nor who has permission to alter them. There is at least one charm that affects only dementors, so its possible that the wards might be able to detect dementors but not trolls, but that's just conjecture. Finally, if there is no way this could have been organized by anyone but a Hogwarts professor, then the finger of blame points squarely at Quirrell, and I think Quirrell is smart enough to avoid that (e.g. if magical creatures cannot be sneaked past the wards, why not smuggle in a lion and cast spells on it to stop magic affecting it?). Therefore, when Dumbledore looks at the evidence there is going to be sufficient doubt over who did it, and also the secrets of Salazar Slytherin will not be implicated. If Quirrell can devise a plan to break Belltrix out of prison, he can murder a girl without getting caught. Not to say that Harry won't realize it wa

OK. was the whole thing with the soup? I think it can only be one of two things:

1) A shout-out/reference to another piece of fiction. HPMOR does this a lot, and I would not be surprised if this was yet another one of those. I do not recognise what piece of fiction it is referencing though. Can I get confirmation from anyone on if they recognise it from anywhere?

2) Otherwise, it must be important to the story. Remember, HPMOR is a rationalist story. There there are not meant to be red herrings. You are supposed to be able to figure it out. So, if this is the case, how has this got to do with the events of the story. Perhaps some weird time travel thing? I do not know. I notice I am confused.

I'm bewildered at why Quirrel thinks he can get any particular result from Harry by having Hermione killed. Or is Quirrel assuming that Harry is now in a state where he can be manipulated reliably?

Quirrell thinks Harry will take the gloves off now and accomplish goals like gaining power without any hesitation. Whatever Quirrell is up to, it seems like he wants Harry to gain power. Quote:

He'd felt the fury the boy had directed at some annoyance who was likely Dumbledore; followed by an unknown resolution whose unyielding hardness even he found adequate. With any luck, the boy had just discarded his foolish little reluctances.

Recall that Harry said the following to Quirrell in Chapter 66:

"Lessson I learned is not to try plotss that would make girl-child friend think I am evil or boy-child friend think I am sstupid," Harry snapped back.

Those two obstacles to Harry trying plots have now conveniently been removed!

The problem with the Time-Turner approach is that (given what we understand of the Time-Turner's rules) he'd have to somehow fool first-iteration Harry (and Fred and George) in order to avoid a paradox. The Methods universe is full of tales of time-turning gone wrong; since saving lives is one obvious application of the Time-Turner, Dumbledore surely knows exactly what he can and cannot get away with in that respect.

No, this is what you'd do: You'd polyjuice another human into Hermione. Thus, when the imposter dies, there would still be the "dying-soul-magic" of a human dying. (Of course, there are the ethical objections of trading another's life for Hermione's, but to be honest, I don't think that would stop Harry at the moment in the state he is in. Oh, and you'd use the Imperius curse or something to make the polyjuiced duplicate do the whole "Not your fault" thing. (Hey, if you're ignoring ethical objections, might as well...)

You don't have to trick out time. You can have it work the way you want from the beginning. Harry didn't have to trick his past self into not knowing that he was being pranked in order to prank himself. That wouldn't even make sense.

He did act in a manner which completely explained what he had previously experienced. I also wouldn't put it past Harry to risk breaking time by refusing to lose to "do not mess with time" over Hermione.
2DanielLC
Your argument is circular. The only reason that it applies here and not with pranking his past self is that he successfully pranked his past self but didn't go back in time here. It doesn't answer the question of why there's a stable time loop of him pranking himself, but not one of him saving Hermione.

Are you objecting to a time travel argument because it is circular?! Of course it's circular, it's time travel. That's the thing about time travel, it makes causal circles. That's why it drives you insane to think about it.

It's about fixed-point solutions. Harry got "Do not mess with time" because he was willing, in that case, to send the same message back. If he hadn't been, he never would have received that message in the first place.

If Harry had been willing to write "101x101" after receiving "do not mess with time", he would have solved NP=P?

If he had been willing to do that, he wouldn't have received "do not mess with time". Though I notice I'm confused as to how, exactly, the universe can figure out he'd create a paradox in this situation without actually running the computation to see what happens. Probably it can't. Probably time-travel is hilariously unethical.

The universe isn't limited to object-level proofs that exist in the universe, I guess. Perhaps the universe has access to the list of everything which is true about the universe?

I don't. It's not accessible from the object level, or any combination of first-order meta levels. it takes at least a second-order meta (2°meta:1°meta::1°meta:object) to create such a list, and I can't even begin to explain what second-order meta means.

All right, so long as you realize that means you can't evaluate whether or not such a thing is possible. :-) Argument from confusion doesn't work.

Well, I can consider the analogous situation where time travel is repeated in an attempt for Emperor Yingling of Scandinavia to convince all of his respective kingdoms to adopt ultimogeniture secession before he dies, so that his youngest son won't have to fight secession wars as he tries to expand into Rus while defending Aragorn from upstarts who object to imperial expansion by marriage.

I was thinking about how I'd implement HPMoR-style time-travel in a turing machine, actually. It goes something like this: * Compute every possible future that doesn't contradict something in the fixed past, including loops. * Whenever you find a paradox, delete that timeline. * Repeat. That would generate a story we could read, no problem. It wouldn't generate anyone who actually experiences paradoxes, either; to the degree those actually exist, they never get out of the subatomic level. It's not clear to me whether or not this results in a universe that can usefully be experienced, though, or (more to the point) whether your future experiences match up with the type of experiences you remember. ..kind of odd.

It's not entirely obvious what causes a given stable time loop, but that doesn't mean there is no way to predict it. Even if it's random, it has to have some kind of probability distribution. Time loops isn't an excuse for an author to do whatever they want. At least, not if they want it to take place in a universe based on rules and not narrative causality.

You only travel back in time if you've already arrived. I don't think "can" belongs there. You only travel to New York if you arrive, but you don't say that you only can travel to New York if you arrive, even though it's impossible to leave for New York and then disappear into the ether. I can't seem to parse this sentence. Please restate. We know that Harry won't successfully use his Time Turner from the fact that he hasn't arrived in the past, but we don't know why.
0Decius
... That was lack of sleep talking. And right now that we only know that Harry's attempts to travel back in time doesn't appear to stop Hermione's death. That could be because for some reason Harry is unable to convince or blackmail Dumbledore and unable to defeat a simple casing despite knowing partial transfiguration, it could be because of an as-yet unstated limitation on the use of time-turners (which would be the bad storytelling trope known as "ass-pull"), or it could be because the same enemy which buffed the troll also takes precautions against counter-turning (for example, by taking meaningless information from 1800, encoding it into the junk DNA of some yeast, and putting the yeast into dinner; I would expect a smart dark wizard to consider something very analogous to this, and it takes a master of stable time loops to go back in time BEFORE eating the food, thwart the troll and save Hermione, then set up a fake troll and fake Hermione so that you can convince the enemy that their plan failed so that they later spend their re-do on attempting to stop yours)
0Intrism
Hmm. You're right, that particular oddity ''did'' work. Has anyone here noticed conclusive rules about when a paradox will and will not form? ... Anyhow, though, if a Time-Turner could be used without paradox, it wouldn't be here. When Hermione was missing, it would have been very, very easy to make her missing somewhere safe, without changing anyone's observations. The fact that we got to the death scene without that happening, or any other visible Time-Turner intervention, tells me that it probably can't happen.
3DanielLC
It's not clear what happens when there are multiple possible stable time loops. For example, why he ended up with a paper that says "DON'T MESS WITH TIME TRAVEL" instead of the semiprime factored, even though either would work. However, it can't do anything that results in a paradox. If Harry's going to go back and try to save Hermione whether or not he sees his future self save her, there is conceivable some loophole in which she is not saved, but it seems much more likely she'd just get saved. This isn't like trying to factor a semiprime. This is like trying to write a specific phrase and send it back. You can mess it up, and if you don't get anything back you know you did, but it doesn't seem very plausible.
0Alsadius
Because if he'd gotten back a number, he would have kept pushing until he did something that broke time, thereby causing a paradox. The only way to head off paradox was to cut his line of inquiry off then and there.
0DanielLC
One of the established rules was that information can't be sent back more than six hours. Would he have broken time within six hours? Also, there is always a way to head off a paradox. Consider the multiple universes model. What came out of the time machine in one universe is a function of what came out in the last universe. Furthermore, it's a continuous function. Theoretically, you could do something like send back what came out plus a mote of dust, but I think it can be assumed that there's a limit to whatever the time turner can bring back, meaning the domain of the function is bounded. Since every continuous function mapping a bounded set into itself has at least one fixed point, there must be at least one stable time loop.
0Alsadius
Addendum: Why would it be a continuous function? Human decisions can be binary. Consider, as a trivial example, "If I see 1 on the paper, I'll write 0 and send it back in time. If I see anything else on the paper, I'll write 1 and send it back in time".
1DanielLC
Humans are made of atoms. Atoms behave continuously. Therefore, human decisions are continuous. A human can no more follow the algorithm you gave than Buridan's ass can follow the algorithm of "Eat the bigger bale of hay first, or the one on the left if you can't tell which is bigger". There is the whole quanta thing with quantum physics, but when you get to that point there are bigger problems. Which future does the Time Turner come from? How can you have single universe time travel when the physics you're using already established more than one universe?

I think this is the compositional fallacy: Humans are made of atoms. Atoms are smaller than pennies. Therefore, humans are smaller than pennies. I don't mean that your conclusion is false, just that your argument is (as read) invalid.

Let me rephrase that. Humans are systems of atoms. Systems of atoms behave continuously. Therefore, human decisions are continuous. It's the same principle that lets me conclude that any machine you make obeys the law of conservation of energy when all I know is that it's made of atoms.

0DanielLC
What measurement error? If there was some sort of god that was not quite omniscient that tried to find a self-consistent timeline, then it would have a hard time. To my knowledge, there's no way that god could generally even be sure any given point is anywhere near a stable time loop, no matter how precise its measurement. I don't get the impression there is such a god. It's just that one of the self-consistent timelines happen. The universe has a set of laws of physics and a set of initial conditions, and some timeline where all that applies happens.
0Qiaochu_Yuan
What does "behave continuously" mean?
0DanielLC
It means that a sufficiently small change in the initial value will cause an arbitrarily small change in the final value. This is true for real life systems, but if you had a truly binary system, it wouldn't be. For example, if you have a switch that conducts electricity if it's flipped more than half way, and you flip it exactly half way, then if you flip it any more, no matter how little you move it, it will instantly go from being an insulator to being a conductor.
1Qiaochu_Yuan
This is true of a particular model of reality, namely classical mechanics, but it seems to be a contentious claim that it's true of reality itself. AFAIK physicists take the possibility that reality might be discrete fairly seriously.
-2DanielLC
To my knowledge, it's true of every model of reality. There have already been stable time loops in both canon Harry Potter and in Methods. If the universe is discrete, there won't generally be a stable time loop. It's not going to take Harry trying to break time to cause a paradox. The universe is chaotic. Not every aspect is, but that's not necessary. If you go back in time one way and look at the Brownian motion, and go back with the initial conditions changed by one, the Brownian motion will be completely different. It will basically be random. If you make a random bijection, the probability of there being a fixed point approaches roughly 63% as the domain increases. Thus, if the universe was discrete, and obeyed the law of increasing entropy, then there would only be a working time loop about two thirds of the time even if you didn't try to prevent one.
0Alsadius
Knowing HJPEV, yes, he would have broken time within six hours. He wouldn't have even had much trouble doing it. And yes, there's a stable time loop. It's the one where he writes "DO NOT MESS WITH TIME".
0DanielLC
He already went back in time once. He knows he's not supposed to go back more than two hours a day, and while he breaks that rule quite often, he wouldn't do it for something as minor as not wanting to wait until tomorrow. If he was going to use the time turner again, he'd have just only gone a half-hour back from the beginning.

Mild evidence against is that Time Turners were (apparently) used to save a life in canon, namely Buckbeak's. Stronger evidence is that no use of a Time Turner in HPMoR has actually altered the timeline; to the extent that there are rules I would expect them to be much more general than that. "Can't save a life" is a deeply inelegant rule. It doesn't cut the universe at its joints.
775th
Can't tell by your phrasing here whether you're aware of this or not, but no use of a Time Turner in canon altered the timeline, either. Everything that Harry and Hermione did while time-turned was exactly what the trio saw the first time through. That part of HPMoR's time travel rules are identical to canon's, just more thoroughly explained.

Yes, that's what the (apparently) was for. The point is that this is a canon example where a character thought someone was dead and used a Time Turner to rescue them, but the timeline ended up working out so that they were never dead in the first place (as it had to).

dthunt is right. The prominence a female character has in the storyline before her death doesn't really affect whether it is or isn't a fridging. What matters is whether her death is a narratively appropriate end to her story and character arc, or whether her death primarily serves to motivate a male hero and further his heroic journey. (See http://www.feministfrequency.com/2011/04/tropes-vs-women-2-women-in-refrigerators/ for a full discussion.)

Hermione's death was a textbook fridging. That's not to say that it's automatically offensive or sexist or whatever: like TVTropes says, tropes are not bad, tropes are tools. But yes, Hermione's death is a classic fridge death.

Your summary is a much better definition of 'fridging' than the one which appears on TV Tropes and should probably be added there, since TV Tropes is where I went to look up 'fridging' whereupon I was much puzzled by the accusations. But as the application of your definition deals with future events within HPMOR, rather than things which have already happened inside the story, I cannot comment further.

She's a fridge death.

...unless and until she returns from the dead, in which case you'll have used her death to motivate her. Gosh, I'm embarrassed to have forgotten that death doesn't have to be forever. Even the introduction of the Blood-Cooling Charm wasn't enough of a clue.

She died at age twelve. There's a limit to how much she could have accomplished - frankly, we're well past the point where accomplishments of preteens are straining the suspension of disbelief in this story, I'm just accepting it on the grounds that any story is entitled to one ludicrous premise.
1[anonymous]
I'm currently expecting that, once she wakes up, Hermione's firsthand experience of death will drive her to rediscover the Philosopher's Stone, not to pay off Harry's debts, but to end death altogether. Harry's quest is to defeat the symbolic Death at Azkaban, and Draco is apparently supposed to heal Slytherin House and end the prejudice against Muggleborns, however one would do that. So I hope you're wrong about that limit, because it'll make for a depressing ending; there's no shortage of problems to solve and no adults stepping forward to tackle them.

If she gets more time on this planet, the upper bound of what she can do will of course increase.
2MarkusRamikin
That's precisely it, well put. I'm not very happy about this death because it's not like Hermione the character couldn't possibly go anywhere any more, or her relationship with Harry for that matter. All that getting invested in her, all that development and "self-actualisation", and it ultimately ends in a "not your fault" for Harry? It may get extra points on LW for being "realistic" and allowed to happen, but I don't care; as a story I find it, well, somewhat unfulfilling. EDIT: actually, Hermione being a girl isn't any part of what personally bothers me here (my feminist goggles are almost nonexistent). It's the killing off of a promising character we were invested in before they achieved even a fraction of their potential.

The trope requires 2 things: 1) The woman winds up in the refrigerator (check) 2) It happens because someone is explicitly trying to get at somebody else, thus disempowering the victim, or that it serves as an empty source of motivation for a character. (???). As readers, we don't necessarily have confidence in criterion #2, here. Other commentators have come up with various plausible-sounding explanations for how the deed went down (sunlight resistant troll lures Hero-Hermoine to a place where her injuries can't be detected, and systematically removes all of her defenses). So, let's posit that the troll is a weapon explicitly sent to kill Hermoine. The important question is who and why? If it's to get a rise out of Harry, that's it falls under the common heading of the trope. If it's Mr Malfoy trying to get revenge for the destroyer of his son's reputation, it doesn't. I think as readers it's difficult at this stage to be confident about these things. Let's say, however, that Hermoine is the woman in the refrigerator. The road to get there had her basically kicking ass and taking names the whole way there; I'm not inclined to necessarily cry foul because of it.

Well, forgive me for overstating my point in a state of emotional frustration, anguish, anger, disappointment, and just plain loathing. No, it is technically not correct to call this Fridge Stuffing. Nevertheless, the fact is that my willing suspension of disbelief is broken, and that I find that my anger is directed at you rather than at the Universe or the Rules or Fate or whatever forces make the death of a beloved main character acceptable. My brain rejects this. I've never, in my life, until now, felt like declaring a piece of fiction DisContinuity, but this is exactly how I'm feeling now. If she had died in Azkaban or from a Kiss or from a Malfoy-funded assassination, that would have perhaps felt better. But the lamest warmup boss of the canon? Offscreen? And making Harry arrive just too late? Not minutes too late, mind you, but right after the troll grabbed and crushed her? What, would just a few paragraphs of seeing the fight from her perspective have hurt? A sense of closure, perhaps, at least on her side?

Isn't that the point, though? Hasn't that been the theme? That reality doesn't care about the narrative arcs that you make in your head? That at any time, the universe is allowed to kill you, your notion of the plot be damned? What you are feeling seems to be more or less the author's intention - the sign of a good story.

Mind you, if this was the real world. Harry would have found out about Hermione's death 2-3 days later, not dramatically just in time. From a realism perspective, there was way more closure than anyone ever actually gets when it comes to violent death.

Not at all. HPMOR isn't quite as full of narrativium as the canon, but it's hardly a Game of Thrones-esque "The plot doesn't care about what you want" slaughterfest.
2MalcolmOcean
Pretty sure that's what Ritalin was complaining about. It made the scene seem flat/tropy. Not that I can necessarily propose a better way of doing it. Also no, it would have been at most later that day. But still.
0Ritalin
Especially since the tension up to that point had been incredibly generic. Honestly, I found that the chapter was a bore, an incredibly standard race-against-the-clock Hollywoodish action sequence, and never, at any point, did the narrative properly convey that this situation was any different from the myriad other situations where the hero bypasses a traffic jam by driving his car through a mall so that he can get to his beloved in time. The only other instance I can remember of something like this happening was in The Dark Knight, and there too it felt like an unnatural cheat, but at least we had the Joker's malice to blame.
1CAE_Jones
Voldemort has plenty of malice to go around. It's just less chaotic than the Joker's. Where the Joker would kill you with an overly complicated punchline, Voldemort would simply kill you.
-2Ritalin
That's not malice, that's just indifference; not the act of a villain, but that of an Eldritch Abomination. Though it is true that hurting people seems to be a terminal value in his utility function, and that seeing others suffer brings him hedons... What's up with this asshole anyway? Regardless, my bet is that Snape killed Hermione.
[-]ArisKatsaris270

I don't know why you think seeing the fight from her side would have made it feel better for you.

I think you're probably just mourning for the character and are angry at the cruelty of the story that depicts a cruel universe which lets people cruelly be murdered (just like our own). You're justifying your anger by talking about the particular details of the depiction -- but I think you're just bloody angry at the murder itself, like Harry is, not anything else.

If that's the case I think the story has been successful in making you feel Harry's anger, though you're misdirecting it. Authors that write honestly end up writing about the moral universe of consequences which they believe exists. An atheist like G.R.R. Martin couldn't write Lord of the Rings, and a Christian like Tolkien couldn't have written Game of Thrones. And this is the story that Eliezer Yudkowsky has to write.

Details like "in the canon the troll was much weaker" seriously shouldn't be affecting your emotional reaction, especially when it's clear that the troll has been boosted in power even in-story (so that it'd be impervious to sunlight), so it was clearly murder and targetted assassination, not just a random troll than randomly attacked Hermione.

GoT is absurdly dark, though. Things like that have happened in history, but not so compressed in time. After I found out about the Red Wedding, I gave up on the entire thing, I found myself completely losing interest. "I don't know why you think seeing the fight from her side would have made it feel better for you." I anticipate that I would. If I had to venture a hypothesis as to why, I'd guess that I would have shared her struggle, her despair, and her eventual acceptance of death. Part of me would have struggled, failed, and died with her. Inability to help oneself is much more acceptable than inability to help others. And, of course, seeing the fight from her perspective would have given me time to get it into my skull that she really was going to die, before she did.

This is historically inaccurate. GoT is fairly accurate for the time period depicted (it is based loosely on the War of the Roses). It is practically lighthearted compared to the vast majority of human history.

After I found out about the Red Wedding, I gave up on the entire thing, I found myself completely losing interest.

The Red Wedding, like most of GoT, is based on a historical analogy with the War of the Roses. Specifically, it is a combination of the Battle of Heworth Moor, where a wedding party was warned in advance of an ambush and managed to hire enough mercenaries to survive, and the Black Dinner, where the leaders of a clan were invited to dinner, then slaughtered.

Usually the War of the Roses isn't portrayed nearly as darkly. Hm. An interesting thing happened in my head. I imagined GoT as retold in the style of Horrible Histories, and suddenly it all became okay and tolerable. "Stupid deaths, stupid deaths, it's funny cause it's true. Stupid deaths, stupid deaths, hope next time it's not you!"

I am currently reading a history of Byzantium. In the roughly three centuries from Constantine to Justinian, a situation with someone invited with guarantees of safety but betrayed and murdered occurs about ten times.

I thought it was a neat bit of subversion where something that would be a joke speed bump mid-boss in Industry Standard Storytelling ends up straight up killing you instead because things work more like reality here and it's ten times as big as you and made of magic.

If HPMOR ran on Reium rather than Narrativium, I can think of a dozen opportunities for any of the characters to die horribly, not just during the plot but before the plot even begins. Why did Voldemort keep the Order alive? As Harry said, a wizard with his skillz and creativity isn't a threat, it's an extinction event.
[-]elharo120

Yes, but only if he wants it to be an extinction event. I'm reasonably confident that HPMoR Voldemort does not want the same things as canon Voldemort. In fact, I give it at least a 50% probability that "Voldemort" was a false flag operation from the get go to achieve some other goal, e.g. uniting wizard-kind against muggle threats.

I think that after getting killed, Voldemort's priorities changed and he's now using it like that.

The one mystery I don't have even a plausible story for is what really happened Halloween night in Godric's Hollow. There have been multiple clues dropped that the canon story did not happen in this universe, and that what the characters (except Quirrel) think happened, didn't. ("And somewhere in the back of his mind was a small, small note of confusion, a sense of something wrong about that story; and it should have been a part of Harry's art to notice that tiny note, but he was distracted. For it is a sad rule that whenever you are most in need of your art as a rationalist, that is when you are most likely to forget it.") I suspect that Voldemort did not Avada Kadevra baby Harry, and he probably did not die that night either. I think Riddle/Quirrell/Monroe/whoever was simply done with the Voldemort supervillain persona, and therefore faked "Voldemort's" death. However I have not yet been able to figure out what really did happen. I suspect the clues are there, but so far I haven't been able to notice them or deduce the proper answer from them.
9derefr
Would you want to give the reader closure for the arc of a character who is, as the protagonist states, going to be coming back to life? Personally, this reminds me more than anything of Crono's death in Chrono Trigger. Nobody mourns him--mourning is something to do when you don't have control over space and time and the absolute resolve to harness that control. And so the audience, also, doesn't get a break to stop and think about the death. They just hurl themselves, and their avatar, face-first into solving it.
1Ritalin
I do not, for one second, that Harry Potter is going to pull that off in his first year at Hogwarts. Or ever. I'd find it easier to believe that he beat Entropy than that he figured how to bring back the dead. While it's true that he's already done things Beyond The Impossible before, all the rules of the setting seem to indicate that Death Is Final. Even his dreams of "immortality for everyone" seemed to be about stopping people from dying, not bringing them back.
[-]derefr110

Not wanting to give anything away, I would remind you that what we have seen of Harry so far in the story was intended to resemble the persona of an 18-year-old Eliezer. Whatever Harry has done so far that you would consider to be "Beyond The Impossible", take measure of Eliezer's own life before and after a particular critical event. I would suggest that everything Harry has wrought until this moment has been the work of a child with no greater goal--and that, whatever supporting beams of the setting you feel are currently impervious to being knocked down, well, they haven't even had a motivated rationalist give them even a moment of attention, yet.

I mean, it's not like Harry can't extract a perfect copy of Hermione's material information-theoretic mass (both body and mind) using a combination of a fully-dissected time-turner, a pensieve containing complete braindumps of everyone else she's ever interacted with, a computer cluster manipulating the mirror of Erised into flipping through alternate timelines to explore Hermione's reactions to various hypotheticals, or various other devices strewn about the HP continuum. He might end up with a new baby Hermione (who has Herm... (read more)

Okay, I'm sold. Shame on me, I was too busy going through the Five Stages of Grief to stop and think about it for five minutes. Of course he'll bring her back. Also, that's why EY didn't give her final moments the proper treatment a Killed Off For Real protagonist deserves; not if but when she is resurrected, that treatment would appear like a cheat and a red herring and a waste of time. And there are no red herrings in this fic. We'll get her back. Well, good, now I can relax and wait to see how Harry pulls it off and at what cost. Good mood, good moo-ood, good moo-ood

While I'm putting it at over 90% that Hermione will be resurrected somehow, someway, it doesn't need to be in his first year.

I got the strong impression that there was more contrived there (in-universe) than the simple matter of the troll catching Hermione when she was out. The amount of time that passes between Harry injecting her and Dumbledore's arrival doesn't seem to be long enough for the effects of the oxygenation to fail. (Will have to reread / research brain death to be sure I'm not jumping at shadows. It does seem that magic, at least, has concluded for sure that she's dead, and Harry doesn't seem likely to have time to save her even if magic is mistaken and she has a couple more minutes before her brain is irrepairably damaged (the time turner feats would be frankly badass if he could pull it off).) All of which leads me to believe that Quirrel (or whoever was behind it) took measures to make sure that there was no hope of saving her short of phoenix tears, unless they took precautions against even those, somehow.
6TimS
Alternative explanation: Magic oxygenation shots don't work because the inventors did not understand biology, just like the inventors of broomsticks did not understand physics.
1monsterzero
And yet the broomsticks work.
0Decius
Easy answer: Dumbledore lied. Answer which doesn't break established characters: A death eater disguised as Dumbledore lied. Answer that I can think of that is the least bad: Quiirrelmort steals !Harry's time-turner and comes back from 6PM to spill the soup and provide an alibi for how he suppressed the wards of Hogwarts (which have been established to detect sudden serious injury of a student- that's why Malfoy had to die slowly), and used the troll to kill Hermione for the purpose of turning !Harry into the person who has the motivations required to complete the intended narrative.

Dumbledore teleported by pheonix. I don't think a disguised death eater could do that.

I'm feeling really confused at this comment. When I read the chapter I thought to myself "Oh. Hermione died. Big plot twist, what will the characters do next?" And not much more than that. I don't know whether I'm emotionally stunted but I find it extremely difficult to conceive of someone having such a visceral emotional reaction to a fictional character's death.
5NancyLebovitz
I was wondering whether a lot of exposure to superhero comics could have that effect, since very little (nothing at all?) is permanent in them.
2Axel
I also lacked any strong emotional reaction to Hermione's death and I have never read a superhero comic in my life. I fact, I've never had such a reaction to a fictional character's death in books, movies or games. While I do get immense enjoyment out of absorbing works of fiction, I never get 'caught up' in them to such a degree that the emotional part of my brain starts treating characters as real people.
0Sheaman3773
I can get emotionally invested, but to me (it appears, upon internal reflection) it is the loss of potential and further interaction with the character that gets to me. For instance, I really like the scenes including X, and I thought that X could have grown and done so much more, and now none of it will happen. Completely different feeling from when RL people die.
0bramflakes
I've never been into superhero comics so that can't be the explanation in my case. In fact I often get annoyed when an official writer mistreats the canon they have been entrusted with, or fails to follow up on important plot points.

Likewise, I find myself shocked when I meet people who don't care about fictional characters the way I do.

I've been really shocked by the super-emotional-effects from fiction that you seen in Tumblr fandom and the like. On the other hand, I get extremely emotionally affected by opera, so I don't know. This chapter was certainly a punch in the gut though, but I came out of it feeling more 'victory - whatever the cost' than you.
1Ritalin
Wow, there's really no escaping the Typical Mind Fallacy. I find it very hard to connect to what's going on in an opera. As for Victory At All Costs, this isn't Star Trek or a shounen anime; the amount of willpower and smarts you put into things increases your base rate of success, but there are some tasks that are just plain too hard, and sometimes you're just unlucky and roll a Critical Fail.
0ikrase
Although I do tend to come out of cathartic tragic operas, plays, etc with a kind of transhumanist "look upon the tragedies I avert and despair" bent. But seeking, for example, how the Universe still manages to kill Gilda is a lot different from this sort of thing.
0ikrase
Of course. But that still is pretty close to Ardent Harry's actual resolve.
0Risto_Saarelma
After decades of constant fiction consumption, I've just stopped taking it very seriously at object level. I imagine I used to be much more responsive to what storytelling beats the narrator pulls instead of how they pull them back when my brain wasn't hypersaturated with familiar fiction schema most anything will fit into.
0bramflakes
I'm a poor visual imager, so perhaps I find it more difficult to empathize with characters when my experience of them is words on a screen (interspersed with blurry outlines of what I imagine is happening in the scene). I notice that I get more emotional reactions when I'm watching a movie, for example. Is there any research investigating this sort of thing?
1JoshuaZ
Unfortunately, while 1 and 2 may be strictly valid responses, they come across as extremely tonedeaf given that there were already a variety of complaints about gender issues in the story. To then kill off the primary female protagonist looks pretty bad. You could have gotten almost the same result if you had killed Neville without the gender issues.
7gwern
Only if he had already been writing a yaoi fic... If he killed off Neville, no one would care and he'd open up a can of plot worms ("why Neville? Why not Hermione?").
3JoshuaZ
On the contrary, I think Neville could be far more poignant. Hermione wanted to be a heroine independent of Harry, because she has those sorts of cultural goals. Neville only started acting remotely brave because of Harry's influence.

Understood. I didn't claim to endorse the above points, but it was unclear to me whether that was what Ritalin was asserting.

All of the above, and more. He didn't just stuff her into the fridge after an entire story of not-measuring-up, and a chapter of bonding and future plans. He killed her off-screen, and then gave us false hope of saving her. And he has the gall to imply that this is Harry's fault for trying to be sensible, for expecting too much of normal people, and for not thinking to use his Patronus. It felt contrived, cruel, and uncaring. "Let's get her out of the way and give Harry a motivation" is the feeling one gets. It was fucking bridge-dropping, is what it was.
[-]Mestroyer160

It is bridge dropping, and I love it. We are being given a taste of a dark rationalist, who does not give his enemies dramatic deaths where they get to die like heroes, perhaps accomplishing something through it. When a dark rationalist takes control of the story (or rather, starts to use the control over the story he's always had), the story becomes contrived, cruel and uncaring, as it should. It's realism.

See also Fate/zero & Kuritsugu. And note that it's not just Hermione's death that is fast and cruel, it's the troll's too: Harry steps forward with the stone, stuffs it in, releases it to explode the head, and acidifies the brains in less time than it takes to type that.

Actually, there's a great rationality quote for here:

Getting caught up in style and throwing away victory is something for the lower ranks to do. Captains can't even think about doing such a carefree thing. Don't try to be a good guy. It doesn't matter who owes who. From the instant they enter into a war, both sides are evil.

Harry thinks this. In general it's not a good idea to assume that authors agree with everything their characters think, and Eliezer has explicitly pointed this out on several occasions.

I think this was deliberate. Have you read the piece Eliezer wrote about his brother?

Okay, the narrative implies this. I frankly don't care what the author himself thinks. And yes, I have. In the context where I read it, it was an uplifting piece about accepting that we live in a difficult world and making the best of it, and about the very obvious fact that death is bad. You bringing this up in this context makes me angry for some reason I don't quite understand.
