Here's my take on what actually happened in the dojo incident described in chp 19.
Voldemort went there in disguise to learn the valuable martial art. He reacted badly to losing so they put him through the ordeal he described. He went along with it because he wanted to learn the martial art. The ordeal did teach him valuable lessons about losing, and he vowed to learn to control his temper and master tactics of ingratiation and supplication to better manipulate others. But he felt angry and humiliated by it (as he expected Harry to be), and also vowed to return and fulfill his revenge fantasies. So after he mastered the martial art and left the dojo, he came back openly as the Dark Lord and killed them to live out his revenge fantasies and to prevent others from learning the skills (keep science secret). He spared one student who had befriended him (and who probably stood up for him during the ordeal, like Draco to Harry), and he had that student spread the version of the tale that he wanted told (to maximize fear while hiding some of his true powers, and to deflect attention away from the value of that martial art).
For me the most natural explanation of the dojo incident is that Quirrell/Voldemort pulled a Verbal Kint. The setup is just too similar to be accidental. If you haven't seen The Usual Suspects (you should), that means ur vzcebivfrq gur fgbel ba gur fcbg gb znxr rirelbar srne uvz naq gb uhzvyvngr Uneel. I'll be quite disappointed if Eliezer's eventual explanation isn't as good as this one.
That's certainly possible, but we know Q/V does have elite martial arts skills, which he had to have learned somewhere, and studying at the world's best dojo, followed by destroying it to make sure no one else ever got training as good, seems like an entirely plausible thing for a Dark Lord to do.
Slightly edited the original post to avoid giving away what my readers have finally convinced me is, in fact, an undesirable spoiler. I also hope you didn't mind my removing the mention of FAI, because I feel fairly strongly about not mixing that into the fic. "A fanatic is someone who can't change their mind and won't change the subject"; if we can't shut up about FAI while talking about Harry Potter, we may have a problem.
The writing style seems to go for similar overkill as in XKCDSucks-blog, that is, every tiny detail is taken out of context and twisted until it is made look bad. Plain honest deconstruction and critique would be fun, as there are many things I think are quite awful with MoR, mostly I dislike the unnatural feeling every single human relationship has and how many speeches about science seem to be a bit unrelated and be there just for lecturing the reader without justification from story, and how Harry seems to be Mary Sue so very much it's actually annoying. MoRSucks however seems to go drowning real bad points into a sea of motivated cognition. It seems bad. Weird and untruthful, strawman-like, as far as I can tell, portrayal of MoR fans doesn't help.
It seems like the spells in the HP universe are complicated and abstract enough that they must have been designed (programmed?) by wizards long ago, who added them to the laws of the universe and left them there.
Now, if I were designing a spell like the Killing Curse, I would include a little easter egg/safety mechanism: after a thousand castings, it backfires. Choose a number large enough that only a major dark wizard like Voldemort will encounter it, so it doesn't hit some minor villain and spoil the surprise. (Alternatively, rather than counting kills, count evilness, with killing a baby counting for more evilness points than an adult. That would explain why it backfired on Harry Potter, rather than some other victim.)
This is the most sensible explanation I can come up with. Or it could be that it backfired because the third through fifteenth places of the decimal expansion of the local humidity were a prime number, or something similarly arbitrary. But I would be disappointed if it was something like that. (I would also be disappointed if his parents came up with a spell that reflected it, because everyone seems convinced that no such spell is possible.)
That was a hard swat at "The Ones Who Walk Away from Omelas".
As for why Harry has such an exaggerated sense of responsibility, it might be that growing up on science fiction thing. A lot of science fiction is set up so that the hero can have a huge effect in a satisfying way. Perhaps Harry should have balanced it with reading history. On the other hand, he's living in fiction, so maybe he's right for his situation.
Lois McMaster Bujold has described sf as fantasy of political agency [1], and I think she's on to something.
I assume that shutting down Azkaban has a political solution rather than a magical or violent solution. This will be interesting to watch.
Why would Snape ask Harry for his take on Snape's past? One of the underlying premises of the story is that the smarter characters (possibly with the exception of Hermione) always have a deeper plan. Did Snape actually expect to get good advice? To be told that all his choices were correct? To have a reason to be angry at Harry? None of these make huge amounts of sense (to me, at least-- I have trouble keeping track of all the scheming), even though the scene was very emotionally effective.
This is basically my review posted to fanfiction.net-- let me know if there's a problem with reposting such here.
[1] The link goes to quite an interesting speech
Lois McMaster Bujold has described sf as fantasy of political agency [1], and I think she's on to something.
Thanks for that link. To rephrase: unlike romance or detective stories, many SF/fantasy stories are carefully rigged to give the "underdog" protagonists huge power over the world. It's scary how much this pattern fits.
It's not quite impossible. He could have roundly blamed everything on James, casting Lily as a pure, victimized, agency-less casualty of his manipulations. That seems to be what Snape does.
Assuming Snape was genuinely hurt by Harry's interpretation of Lily, I would expect to see a fraying between Snape and the Dumbledore faction as Snape questions why he is so faithful to Lily.
Furthermore, the major event in Aftermath 2 is that Snape reads students' minds again-something he agreed not to do under his agreement with Dumbledore. Which is further evidence that he has "gone rogue."
I just read Chapter 27. My thoughts:
"Mr. Bester" - great reference.
Harry is firmly on the 'get absolute power' path. Probably he still thinks he's being cute or knowing when he talks about becoming God. His resolution not to become the next Dark Lord doesn't look too healthy now, though.
Harry seems incapable of seeing the flaws in a moral system he apparently acquired by reading science fiction and fantasy, barring almost being Sectumsemprad by a very angry wizard. Why does he think that having read books with monomyth plots is sufficient reason to try to act like the heroes of such books - what is he, eleven years old? At the same time, he understands and can nervelessly put to use Quirrell's very subtle lesson in levels of deception. Very odd, that.
Is one of the reasons Quirrell set up those Occlumency lessons that Harry would discover for himself "how reproducible human thoughts were when you reset people back to the same initial conditions and exposed them to the same stimuli" - and thereby come to treat humans as simple machines that one can use like puppets? As a strategy to bring someone over to the Dark Side, that's brilliant.
Then we get to Harry being placed in the same conditions as Lily Potter, and reacting differently - more humanely. Because he reads science fiction! That's outrageous. Surely this kind of narrative based morality, where you imagine what the good protagonist would do and then do that, is going to be a piece of cake for Quirrell to subvert.
I'm reading MOR with considerable interest and enjoyment-- and recommending it-- but.....
There's a big emotional difference between HP and MOR. In the original, Harry has no friends or allies at the Dursley's. In MOR, his family life isn't great and he doesn't seem to have any friends or anyone he's expecting to miss, but he isn't under constant attack.
Part of the emotional hook in HP is that Harry is almost immediately in a circle of friends and acquires a family in the Weasleys.
In MOR, his best emotional connection is to McGonagle, but it's complicated by his intellectual dominance. None of his close friends from HP are worth being close to (or did I miss someone?). His nearest approach to a friend his own age is Draco, and that's very much complicated by Draco having been raised to be a sociopath, and by Harry's need to manage Draco.
Part of the charm of HP was that Hermione's memory, intelligence, and conscientiousness are presented as more valuable than annoying, though the annoyance for the other characters is still there. This is a rationalist feature of HP which seems to be lost in MOR-- Hermione is interested in getting things right for the sake of status.
Her delight at ...
that's very much complicated by Draco having been raised to be a sociopath
I need to object pretty strongly to this particular phrase. Draco is not being raised to be a sociopath; he's being raised to be a high-status member of a hierarchical society. Draco and his father very much love each other, and are perfectly capable of making real emotional bonds with people that they have identified unequivocally as 'pack'. EY has actually done very well at showing Draco as what a perfectly normal child becomes in that environment.
This is an important distinction, because we need to remember that 'sociopathy' is a comparatively rare (and usually inborn) condition, while high-status machiavellian narcissism is a natural consequence of human evolutionary psychology.
The hate that the Dark Lord Potter forum has on MoR is getting more than a bit amusing.
...Also, perhaps it's me, but I see the story as a thinly veiled commercial for the author's blog/institute, which breaks the "doing this for pleasure and not profit" fanfiction model (as well as being a subtext that breaks the fourth wall for several readers). The author is almost certainly deriving commercial benefit from J. K. Rowling's intellectual property and his exploitation of the popularity of her fandom by routing eyeballs to his site and building his own personal fame as a voice in the field of AI. I wouldn't be surprised if his story has bumped traffic to his blog/website by an order of magnitude or two. In many regards, this practice is worse than a Cassandra Clare or Jim Bernheimer pitching their original fiction novels on their fanfiction sites, since neither author makes a living off their writing.
This story isn't parody in the traditional sense, so it's possible that a court would consider it as not falling within this protected class of derivative works. Indeed, if the legal hammer were to fall on this story, it could have fallout: consider that a single CAD letter, if
What happened to the Harry from Chapter 6?
"Um," Harry said, "can we go get the healer's kit now?"
McGonagall paused, and looked back at him steadily. "And if I say no, it's too expensive and you won't need it, what happens?"
Harry's face twisted in bitterness. "Exactly what you're thinking, Professor McGonagall. Exactly what you're thinking. I conclude you're another crazy adult I can't talk to, and I start planning how to get my hands on a healer's kit anyway."
A time turner is a superior to a healer's kit in very nearly every way and by a huge margin. Yet all Harry does when he loses free access to his time turner he sulks a little and that's all. He doesn't plan at all! I don't even recall one line of introspection on the subject! It takes very little ingenuity to to react:
"Harry, give me your time t..."
shit. shit. shit. Activate time turner. Escape. Then, he can spend five minutes and think up a dozen ways to retain time travel capability. Let me see...
First, Harry discovered a gag beverage that he thought could be a key to power, although he quickly realized the Comed-Tea wasn't as powerful as it seemed. A few days later he fell in love with a device that is sometimes given to students who want to take extra classes, although he has since discovered some limits to its powers. If he goes rogue over his Time-Turner's crippleware, then who knows how much other cool and useful magical stuff he will miss out on, and how much trouble he'll be in.
Plus, McGonagall had him cornered when she confronted him about returning the Time-Turner - whatever he tried to do, she'd see it. Also, McGonagall had earned some degree of trust & respect from Harry, she's correct about Harry repeatedly misusing the Time-Turner, and she'd already warned him that they'd take it away. So it's not unreasonable to go along with the punishment, and try to earn her trust back so that his Time-Turner can be restored later on.
You seem to misunderstand how the time-turner works (or at least, how it's been suggested it works). You don't get to overwrite anything; the universe doesn't "end up in" a stable state that results from using it
My interpretation of the "DO NOT MESS WITH TIME" incident was that you can try setting things up so that temporal consistency implies the result you want, but actually ruling out every other possibility whatever, including vast classes of outcomes you never even imagined, is next to impossible, at least for an 11-year-old boy, however smart. It hadn't even occurred to him that there was a problem in his reasoning when he tried the experiment that gave him "the scariest result ever in the history of science". Temporal consistency in the presence of time loops is another blind idiot god, far more swift and powerful than evolution.
Anyway, he still has the Time-Turner. All that stands between him and it is a magical lock. How difficult can that be for him to get around? No, actually what stands between him and it is the author's necessity not to unbalance the plot by giving him a get-out-of-jail-free card.
once McGonagall sees Harry disappear, he can't undo it.
Sounds like UDT might be applicable here. Here's a time-traveling version of Counterfactual Mugging:
Harry appears to McGonagall and tells her, "If you give me 1 Galleon now, I'll go back in time and hand you 100 Galleons an hour ago." Suppose McGonagall does not recall being handed 100 Galleons an hour ago. What should she do?
Here's my analysis. Suppose McGonagall decides not to give Harry 1 Galleon, then there are two possible consistent timelines for this universe. One where McGonagall gets 100 Galleons, and one where she doesn't. How does the universe "choose" which one becomes reality? I don't know but let's say that the two possibilities have equal chance of being true, or get equal amount of "reality juice".
Given the above it seems clear that McGonagall would prefer to have pre-committed to "give 1 Galleon even if not handed 100 Galleons an hour ago" since that would make the "not get 100 Galleons" timeline inconsistent. I think that's also UDT's output (although I haven't written down the math to make sure).
ETA: I didn't follow the previous discussion closely, so this might not apply at all to it. Hopefully, in that case the above is of interest in its own right. :)
Good heavens Mr. Yudkowsky, I thought the inventor of Timeless Decision Theory would have a better grasp on how being the kind of person who would make a certain decision can determine what happens
I do indeed.
I've written unpublished fiction about it.
From before TDT was invented, actually.
Harry has not worked all that stuff out yet.
He did work out one important principle so far.
It is called DO NOT MESS WITH TIME.
And considering that he got that result, you seem to have missed some of the implications for how time travel works in that universe which would make it potentially dangerous to try and blackmail reality.
Time travel was the first optimization process I considered which was truly alien enough to deanthropomorphize my thinking; evolutionary biology didn't do the job, but the unpublished story I was writing about time travel did.
What you're suggesting is a bit more potentially incredibly dangerous than you seem to think.
I think that, in the first few chapters, Harry did not give enough credence to the hypothesis that he was simply insane and hallucinating. I think, given the observations he had at the time (his mom claimed her sister was a witch; he got a letter implying the same; a woman levitated his dad and turned into a cat), he should have at least seriously considered it. Certainly those pieces of information are some evidence for magic, but considering what that hypothesis entails — existing scientific knowledge about physics (even at the level of abstraction that we experience directly) is so completely wrong that it's actually possible to make the universe understand human words or intentions, or there's this incredibly advanced technology that looks like it's violating the laws of physics, and it's existed for thousands of years and apparently everyone has forgotten how it works — I think an honest rationalist would have to look into the "I'm cuckoo" hypothesis.
I'm not sure what one is supposed to do upon concluding that one is quite that cuckoo. Upon getting that far gone, what can you do? Can you even assume that your actions and words will leave your brain and impact reality in roughly the way you intend? If you are that crazy, and you try to walk across the room, will you get there? Are you in a room? Do you have legs? It might be that being as insane as all that is so game over that, whatever one's epistemic position is, one has to operate as though the observations were correct.
It would be a good idea to consider the hypothesis that one is crazy in a conventional way, such as schizophrenia. One can try to test that hypothesis. But the "anything goes"-crazy hypothesis isn't really useful.
If something totally crazy seemed like it was about to happen and the world was at stake, like a technological singularity was about to occur or something, and I was called to work for the team of great minds that were trying their hardest to stop the destruction of the entire universe, dropping out of high school in the process, and meeting a beautiful girl who had been living literally a few houses down from me for the last 4 years without my knowing about it, who just so happened to be doing an essay on transhumanism for her English class and would just love to interview someone who was doing work for the Singularity Institute.
Oh wait...
I just finished reading the Russian novel "Lena Squatter and the Paragon of Vengeance" by SF author Leonid Kaganov. It's not exactly a Harry Potter fanfic, but it's very similar to MOR in that it tries to present an explicitly rationalist hero, and IMO Kaganov has handled the task better than Eliezer.
The protagonist is an unattractive and immoral woman whose only strength is extra rationality, which she applies to the sordid and corrupt world of Moscow corporate politics. Using the familiar LW intellectual ammunition - from Pascal's Wager to evolutionary psychology - she gets people fired for talking back to her, gives and takes bribes, blatantly manipulates men (driving one to attempted suicide), and then in the end when she's found the perfect boyfriend her plans neatly backfire, forcing her to kill him and then herself. Lena's exploits are shown with a lot of detail and believability, and overall the book has punched me harder than anything Eliezer wrote. Unfortunately it's unlikely that it will ever be translated into English.
It looks from my casual observations like the difference between pirated and not pirated (as opposed to plagiarized and not plagiarized, which is a different matter) isn't whether something is in the public domain, but whether it is freely available. As long as it is easy to get a work for free from the author's preferred distribution method, there's little to no incentive to get it with more hassle from a different distribution method. So putting his prior works in the public domain probably isn't getting this author many bonus points, compared to an author who retains copyright or Creative Commons licensing but still makes the work freely readable.
There is no way that he addressed every possible concern to the satisfaction of his audience while charging money for his book. Money is a concern, and while his book might be inexpensive, adopting a general policy of buying inexpensive books when someone asks nicely isn't, and making many individual decisions about when to buy them and when not to isn't either. To an audience accustomed to getting reading material for free, a demand that they shell out money for a new book feels like extortion, and that provokes negative affect ind...
Reply to this comment if you found LW through Harry Potter and the Methods of Rationality!
A survey for anyone who cares to respond (edit: specifically for people who did find LW through HPMoR):
That which can be destroyed by the truth should be.
(On the other hand, Michael Vassar often claims that this quote is as disingenuous as a strong man saying "That which can be destroyed by lions should be.")
Are you asking because you don't know, or because you want to know which ones BohemianCoast noticed?
Most of the world is wrong. Formal education is overrated. The world as we know it is may cease within a century. Lots Of Math. Simultaneously mentioning the word quantum and talking about psychology. For that matter, mentioning the word quantum.
Those are just the ones off the top of my head, and I'm not BohemianCoast. But a lot of stuff written here (and in the "Sequences") is true despite setting off nutcase detectors, not without setting them off.
Several speculations/thoughts/questions:
First, did baby!Harry actually in fact survive the killing curse? ie, perhaps the curse successfully detached baby-Harry's-soul (presuming that something like "souls" exist in MoR... given the presence of Horcruxes, I'll tentatively assume yes), but the body was immediately made into a Horcrux... so Voldemort-soul-shard effectively inhabited that body. Essentially Rationalist!Harry is actually more like what Voldemort would have been like if raised in a loving and sci-fi and science loving family.
The Hat did say that if there was bits of the Dark Lord's mind there in addition to Harry, it would have noticed the extra "passenger"... But in this case there really is only one mind/soul/whatever. The catch is that mini-mort is all that's there.
This brings up the possibility of if this was an accident or deliberate. Perhaps Voldemort actually deliberately planned/faked his apparent "death"?
(Possible related, well, possibility: How do "we"/they actually know Voldemort even used the Killing Curse that night, as opposed to doing some other thing? ie, how is it known that he is the Boy Who Survived the Killing C...
Here's what I think will happen:
Zabini stuns himself in the name of Sunshine to create a tie. And here's why:
1) The rest of the school is very partisan about their favorite army, so it's not likely that many are betting on a tie. Zabini (through a proxy or otherwise) put all of his chips on "tie." So he will return to Hell a much richer Prince of Darkness.
1a) "Aftermath" scene: Hogsmeade. Zabini meets his broker. Hogwarts is basically a closed economy, and Zabini has now walked off with the lion's share of the student body's dispos...
I'm guessing that Blaise will shoot himself in the name of Sunshine, tying all the scores. That seems like the kind of thing Dumbledore would plot. It makes the most sense from Eliezer's point of view too, in terms of leading the story in a more interesting direction.
Chapter 30-31: Was there a more sophisticated basic idea than appearing to be incompetent, then playing possum? I'd have expected one of the other two armies to expend a second (double tap) sleep spell on the downed, given that Neville came up with the same tactic later on.
Also, nice touch writing Neville as Bean without using a sledgehammer on the parallel.
ETA: It took me a bit to understand Draco's particular revelation: that Quirrell made sure to place all the other smartest students (and the other candidate generals mentioned in Ch. 29) on Sunshine.
Well, Hermione wasn't just appearing to be incompetent in the sense of "too stupid to calculate the correct solution;" she was appearing to be irrational in the sense of "too self-righteous to want to calculate the correct solution."
Also, note that Hermione actually did stay true to her goals: her possum tactic allowed her to avoid "unfairly" choosing who to attack first. By waiting until most other players had been sleepified, she was able to attack only the strongest or luckiest survivors, rather than the soldiers controlled by someone that she personally disliked. She was able to both win the game and stay true to her values because she (somehow) was much better at working in groups than Draco or Harry. One wonders how a girl who had no social skills in Chapter 3 suddenly became so socially adept -- has she been reading books on how to get along with people?
There were 24 people per army, and 11 of Sunshine came at Harry and 12 at Draco. And Harry & Draco had their realization of what happened when they remembered that Sunshine's soldiers went down immediately at the first shot. They were playing possum (all but Hermione, who didn't want to risk it).
The 6 soldiers left is after the battle of Sunshine's return, after they've already taken Potter hostage.
Read up to Chapter 21, commenting on chapter 2. Prediction about the physics of HP:MR.
Harry is mistaken about McGonagall's transformation into a cat breaking conservation of energy; indeed, it seems to me that he is not really putting a lot of effort into finding an alternative explanation, but jumping straight to "Everything I thought I knew was wrong". (Perhaps Lord Kelvin's not the only one who gets a charge out of not knowing something; after all Harry has been wanting to do Something Big, and the more laws of physics are broken, the better!...
I really enjoyed the series and hope it continues. I have a few comments.
Eliezer had already stated that one intention of his was to make writing fun again, while writing his rationality book. Hence, I guess once that boost is achieved, this litlle jewel will probably lie around unattended for a while.
If the other, more important, purpose was to raise the sanity waterline, then regular updates might be expected as this would be a serious attempt at reaching people through other means.
Doing a quick drake equation analysis of this strategy
P(Positive outcome...
The idea of promoting Less Wrong (and rationality in general) via Harry Potter fanfiction is so outside the box that I really shouldn't be surprised that it exists! What a great way to tap into a particular group of people that may not have necessarily found their way here otherwise. I wonder if we'll get any users to come out of the woodwork and say they've found LW through the fanfic?
I hope we see more projects like this (from anybody here) in the future!
wave Hello! Brand new, just discovered the site through the fanfic, and still in the looking-around stage... but yes, it does work.
It definitely helps that it is totally frelling awesome fanfic. Admittedly, I'm biased; I'm writing a Potter live-action role-playing game one of whose goals is to figure out how the heck that tacked-together universe could possibly make sense, and what would explain the observed evidence... ;)
I can also report that I have at least two friends who started reading the sequences after encountering HPMR.
Another point in chapter 32 that could use some explaining: Why are Harry, Draco, Hermione the only ones in the running for the Christmas wish? Do Quirrell points from battles tend heavily towards the generals? (Though I guess they were all doing especially well in the class anyway...) That, and there's only one Christmas wish, for all seven years; obviously the other years are a bit outside the scope of the story, but with no explanation it still seems a bit strange that noone from those years would even come close.
Chapter one, when Petunia is talking about how she wanted Lily to use magic to make her prettier:
..."And Lily would tell me no, and make up the most ridiculous excuses, like the world would end if she were nice to her sister, or a centaur told her not to - the most ridiculous things, and I hated her for it. And when I had just graduated, I was going out with this boy, Vernon Dursley, he was also fat and he was the only boy who would talk to me in college. And he said he wanted children, and that his first son would be named Dudley. And I thought to my
Chapter 28: I wonder what happens if Harry realizes he's living in fiction, and everything he's dealing with is made of concepts rather than atoms.
Which leads me to think about the people who say that if they found they were living in a simulation, they'd try to get out. Unless the simulation is very similar to the substrate, would it be possible to get out while remaining yourself in any sense?
Back to the story: This might be an argument for checklists: Harry and Hermione should review precautions before they try anything new, should they be doing it with...
Since around Chapter 20 this is actually my guess for the entire basis of magic that Eliezer is working from. That is... there's a jumble of ideas and tropes that are invented and sequentially stolen by one author after another. Someone tells stories of Vlad Tepis, Bram Stoker comes along... and N iterations later you've got Twilight with vampires having extra chromosomes and clairvoyance.
To understand a magical universe at the deepest level is to see the hands of previous authors influencing your physics and history (and possibly your future if you are in a prequel) plus a "current author" who has a measure of finer grained control over things like plotting and characterization - limited by the audience's willingness to play along.
If this theory of magic is right, rationality in a magical universe should lead you to to become genre-aware, and then the next obvious(?) thing is to go meta genre-aware and start trying to "genre hack" your universe and see if you can "tunnel" into the derivative works (or maybe just get the author to fall in love with you or something).
My current working theory is that Dumbledore as figured out a rough outline of these ...
My hypothesis is that thus far he's considered poor Alissa to be the most inconsequential thing ever to intrude on his thoughts; and having thought more deeply about what happened with him, Lily, and James when he was a kid, he now decides he ought to her to nip her affections in the bud for clearly stated reasons, rather than letting them fester without suitable closure for, perhaps, an unduly long time as his have. His only closure was that he insulted Lily and felt guilty about it forever (as apparently, from his perspective, this was the only thing standing between him and getting to be with Lily); Alissa's could be the end of school, without the issue ever being directly addressed.
The problem with this hypothesis is that it has Snape thinking that student crushes on teachers are persistent sorts of things, and this isn't typically the case.
Ever since the start of this year she'd been having trouble listening in Potions.
This don't mix very well with your hypothesis.
If 'free will' is compatible with physical determinism (including the quantum variety) then why can it not be similarly compatible with living in a world based on some guy's thoughts? The same principles seem to apply.
Chapters 25 & 26
Quirrell is cold. It looks like he gave Rita Skeeter a tip that something would be happening in Mary's Room so that she'd go there as a beetle and he could (literally) crush her. Is Harry going to start to figure him out (like he did with Draco after his reaction to that other newspaper headline)?
Also, does anyone know if Q/V's habit of whistling/humming a tune (appearing in both chp. 25 & 26) is based on something in canon? It sounds like a tell, when his plotting against Skeeter/Potter is going according to plan, but I'm wondering if there's anything more to it.
If you were Harry and were trying to get from "how the hell does magic work" to "omnipotent lord of the universe" what would you do?
I would take Rick Cook's approach - look for meta-spells and figure out how to combine them into something Turing-complete. From canon, we already know that spells can operate on spells ('priori incantatem' or something like that), and I'm almost sure that some spells do logical operations.
If that doesn't work out, start making the Philosopher's Stone. I will know that it's possible, and that's half the battle. Once I have the Stone, then the question of 'fastest method to omnipotence' loses its urgency.
(If this is simply not possible for a 1st Year, then I will set my sights lower on the felix/luck potion; Harry has enough money to finance all the ingredients he could possibly waste, and once you have a vat of luck potion, you can spend it on research in the library, random generation of possible recipes, or direct attempts at creating the Stone.)
Really, you should use it to try to discover a more powerful luck potion, then take the more powerful luck potion to try to discover a more powerful luck potion still, until eventually you get a hard-takeoff scenario where ever-more-powerful luck potions are falling from the sky into your hands by pure chance every second.
After the luck-ularity, Harry can just throw a random rock up in the air, and it will hit Lord Voldemort right between the eyes, killing him instantly at the same time the Pioneer probe crashes into an asteroid.
There's been some speculation on what a +4 spoon would do, so I figured I'd weigh in as an expert of sorts on D&D.
Really, it depends upon what it's being enchanted for. I think the default assumption is that it's enchanted as a melee weapon, and so functions as a diminutive one-handed weapon that does 1d2+4 damage - given the strength of such creatures, you're probably looking at 1d2 damage after the strength penalty, which is a modest improvement over the 1d2-4 (minimum 1) an unenchanted spoon would get you, for the reasonable price of 32,300 gold pi...
From reading it, I got a sense that Eliezer actually has something in mind on how magic works in the story. That would be mindblowing because it would have to be a consistent explanation how magic works, how magicians got to use it, why they loose power over time. And why no physicists stumbled over it by accident.
Is that a shared idea, or am I the only one?
I found this series much harder to enjoy than Eliezer's other works -- for example the Super Happy People story, the Brennan stories, or the Sword of Good story.
I think the issue was that Harry was constantly, perpetually, invariably reacting to everything with shock and outrage. It got... tiresome.
At first, before I knew who the author was, I put this down to simple bad writing. Comments in Chapter 6 suggest that maybe Harry has some severe psychological issues, and that he's deliberately being written as obnoxious and hyperactive in order to meet plot...

I suspect that a main inspiration for writing the story was Eliezer's constant shock and outrage over the fact that Rowling's characters show absolutely no interest in the inner workings of their weird Universe. I vividly remember how outrageous this was for me when I read the originals. Actually, I have only read the first two books, so when I read Eliezer's time-turner scene, I first believed that he invented the artifact and the situation as an over-the-top satire of this phenomenon. Giving young children time-machines so they could attend more classes, yeah right. When I figured out that the whole scene is almost literally copied from the original books, I screamed in shock and outrage just like rationalist Harry did.
Literally laughing out loud, here.
But just to be clear, this story represents my outrage at all scientifically uncurious characters everywhere, and even more than that, my unfilled need to read a story where for just once the alleged "genius" characters are actual geniuses.
I was not picking on J. K. Rowling in particular in any way.
It is a work of Harry Potter fanfiction for the following simple reason:
I knew I needed a rapid feedback loop to motivate my brain to write. That was why I was bogging down on the rationality book.
And to the best of my knowledge of the entire world of online fiction, if you were posting an incomplete story chapter-by-chapter, it would get the most reviews if...
...it were a work of Harry Potter fanfiction posted on fanfiction.net.
QED.
I think I know a place on the internet where you can post books on rationality chapter-by-chapter, and get much instant feedback.
Actually, on reviewing this remark later, it's not quite true. My brain generated an idea set in the HPverse because I'd been reading a lot of HP fanfiction, and I accepted it and stopped the search because it was also optimal for getting reviews. However, I've since read analyses showing that Twilight stories are getting more new reviews on FF.net than Harry Potter, and I don't think I'd have been the smallest bit tempted if I'd known the fact in advance.
I think a version of Twilight with a rationalist Bella as the protagonist would be hilarious.
It'd also be very short, though.
I'm tempted! And come to think of it, I suppose it wouldn't have to be short; I could draw it out by leaning on the right bits of canon...
But I loaned out my copy of the first book ages ago and it's still gone, so I would need to pirate a copy as reference.
All right, all right, I'll at least give this a try. In keeping with the books' title themes, what do folks think of "Luminosity" as a title? (With luminosity as a theme over HP:MOR's emphasis on science, because I don't have the background to competently pull off the science.)
Also, I hate fanfiction.net's interface for publishing stories SO MUCH. I'm probably going to just put the rest of this on my own webspace. EDIT: I am still updating on ff.net to get readers from conventional Twilight fandom, but made the story its own website and have changed the link above.
Also-also, my only account on fanfiction.net is Alicorn24. I am not affiliated in any way with anyone else using the word "alicorn" in their username.
Also-also-also, I'm not quite as much of a review junkie as Eliezer is. However, I a) am unlikely to bother with the story if I'm the only one enjoying it, as I do have creative projects with audiences that could benefit from my attention, and b) plan to treat this as a somewhat experimental work. (For instance, the first chapter has no actual in-quotes dialogue, which I did because dialogue is my strongest suit as a writer and it was challenging to work without it.) Info on what works for readers and what doesn't would be good, as well as periodic reminders that someone's paying attention.
I think some of Harry's annoyingness is due to the fact that he's modeled after young Eliezer. He's a mix of wish-fulfillment for young Eliezer and an opportunity for older Eliezer to criticize his younger self. This is really apparent with the chapters involving the Sorting Hat.
For "Harry Potter and the Methods of Rationality", I'd like to make predictions that can be eventually verified publicly in time, but won't tempt the author to change things to prevent it from coming true (as is the usual way of serial writers on the Internet). I'm therefore encrypting my prediction with the md5 hash function, so that afterwards it can be verified. (One difficulty is that I have the power to edit this comment; is there a way to make it obvious if I've done so, or store it in a less editable space?) Anyway, here goes:
July 16 (after Chapter 31): 28f9e3b2165344763c35514b473cb347
Wow. I liked 28! Well, I liked all but 1 of the previous 27 too but this one was brilliant. Just the right balance of overconfident recklessness combined with not being a stubborn fool when realizing his mistake. By right balance I mean for realism given the character. Harry being such an emotionally unstable prick was a little irritating until he started showing clear signs of being aware of his emotional foibles and the rather important ability to take care of important relationships despite his weakness.
From Ch. 7:
Draco snarled. "She has some sort of perverse obsession about the Malfoys, too, and her father is politically opposed to us so he prints every word. As soon as I'm old enough to get an erection I'm going to rape that bitch."
Is this a reference to some poorly-written slash fanfic? I'm assuming Eliezer knows that boys of any age can get erections, so it must be making fun of something, but I'm missing a reference.
Similarly with:
...Harry burbled on. "I'm delighted to meet you, Mr. Malfoy. Just unutterably delighted. And to be atte
It is expected that villains, even in the canon of children's books, will kill and maybe occasionally torture victims in order to establish that they are bad. It is not expected that villains, especially in the canon of children's books, will permit/condone/commit rape. Additionally, the sorts of emotions that are commonly supposed to precede murder and torture are more familiar than the sorts of emotions that are commonly supposed to precede rape, and so someone unfamiliar with the actual etiology of any of those crimes finds rape less relatable and more shocking.
Speaking as someone who everyone rightfully believes about everything, MoR is awesome (at least up to chapter 21) and everyone should read it. It also might serve as the best introduction to the power of rationality, but we've yet to see that it really makes awesomeness happen in the real world, rather than just for those of us who are cheering on Harry's thoughts.
Hm, inconsistency: I just noticed that Quirrell says in chapter 16 that Quirrell points will determine generalship of armies. That seems to have been abandoned at some point?
Up to chapter 31 now. I don't understand how Eliezer is going to paint the central conflict. Granted, Quirrell is awesome and has had several successes already. But the main motivation of the Death Eaters is blood purism (as in canon), and Harry has already proved it to be false, and our Quirrell is rational enough to agree with the proof if he hears it. So to make the central conflict happen Eliezer has to invent something else, something secret, that makes Quirrell tick.
I previously criticized Eliezer's 'Ultimate Mega Crossover' fic on basically the grounds that it makes him/SIAI look bad, and didn't help out the cause much.
Reading through MoR, I made a point of reading the reviews and seeing what non-LW people were saying. I'm pleased that aside from AngryParsley's site stats, many of the reviews expressed interest in LW writings and Eliezer's ideas, and very few any disgust or general opinions of low status. Good job, Eliezer!
It's really good. I'm on chapter 8, and so far it reads like a picaresque. I never thought anyone would turn Harry Potter into such a badass.
One more thought, this time money related stuff:
On the one hand, the magical and muggle economies are sufficiently separated that Gringots seems to not even notice the possibility of arbitrage...
But on the other hand, we're told that anyone who transfigures stuff to look like money, even muggle currency, is legally at war with the goblins. If the goblins are tracking muggle money enough to at least notice this sort of thing and care about it, that seems at odds with them being sufficiently ignorant of the muggle economy to not notice the arbitrage possibilities.
It's too bad fanfiction.net doesn't provide a Google Reader friendly RSS feed for new story chapters. The author feed doesn't show up as updated when there are new chapters, and Google Reader's page scraping trick for generating a feed doesn't seem to be allowed on the domain.
Chapter 21
Draco's choice of subject. Expected, but unfortunate. It would be fun to know the physics of the magical universe. The biology is not completely exempt from the physics, of course. Also, there can be many fun incidents introduced when they are trying to sample people. Imagine trying to get a skin sample from albus dumbledore, the most powerful wizard around or trying to figure out why Aberforth wasn't that great.
The Dark Mark - They would have thought about it. My guess is the dark mark came around only after a certain power threshold was already...
Chapter 34:
I totally think the "completely wrong ship" alluded to in the author's notes is Hermione/Griphook. It makes sense!
Chapter 33:
I'd come up, before, with the hypothesis that HPMoR Voldemort was actually Necessarily Evil after the fashion of Eliezer's proposed supervillain gambit, but I dismissed it by assuming that Voldemort had crossed the Moral Event Horizon already. This chapter, though, makes it very plausible again via an explicit motivation (and a Shout Out to Foundation, as well). On the other hand, Quirrell could just be playing one level above that explanation.
One thing, though: is it public knowledge that Lucius Malfoy had been a Death Eater? Because it seemed...
Is there an annotated version of this anywhere? I know that the sequences cover most/all the stuff and am reading and have read a lot of the sequences but it seems like it might be fun to read this with descriptions of the maths/science/concepts alongside it as well as all the literary allusion noted.
You know, as I was reading chapter 32, I started thinking about how the three generals had their various weaknesses. Draco is savvy but weak against complexity, Hermione is bright but not exactly street smart, and Harry is clearly brilliant yet arrogant. It was only after I'd read it all that I realised each had fallen prey to their own specific weakness. Hermione was surprised by the combined 'For Sunshine!' Gambit against her, Draco didn't realise he was with the wrong Patil, and Harry encouraged earlier betrayal amongst his crew in order to protect him in the final battle, only to be surprised at the end. I figure this was probably a deliberate bit of writing on Eliezer's account, in which case I just want to say-Good job!
Ch. 32. I don't know what Eliezer will have Blaise do, but if I were in that position I'd flip a coin between Harry and Draco, get rewarded by the winner and counterfactually mug the loser. (Hoping, of course, that that Draco wins, since Harry is clearly more likely to pay off a counterfactual mugger.)
ETA: That is, of course, assuming that Blaise isn't working for Dumbledore (which his chapter-ending line would seem to point to).
Assume that Draco and Harry both value victory at $1000. Now if you demand $800 from the winner, the loser "would have" gained only $200 in the counterfactual case, so he will pay you $200 at most. So you could have just demanded $1000 minus epsilon from the winner. We could probably prove a theorem that says counterfactual mugging can't help you extract more of the surplus economic value that you create.
Edit: Ah, wait, they can't change their allegiance as targets, can they? Otherwise Zabini wouldn't be able to choose the victor at the end.
Chapter 32: Why didn't they (visibly) use change of allegiance for defense in the second phase? If you turn yourself into a soldier of the enemy, then the enemy will lose a point for shooting you. Thus, everyone should hold allegiance to the enemy except for the exact moments they fire (which would be quite hard, since you'd need to find someone with enemy's allegiance who is not loyal to your team).
So, it should've bee...
620 comments is very unwieldy, especially when threaded. A new post per chapter would be less likely to cause brains like mine (that is, unlike Eliezer and Harry's, who seem to have brains built like the TARDIS) to go into terminal explosive overload.
I feel almost certain that Harry is living in a computer simulation. I know he ruled it out because he decided the existence of the Time Turner renders the universe non-computable, but how can he be sure that he's actually going backwards in time instead of the universe "simulating going back to the past and computing a different future?"
Chapter 23: I wonder when Harry will realize that the reason he's an idiot isn't that he doesn't have a perfect emergency kit (though that's important), it's that he doesn't have a gut level understanding that the wizarding world is very dangerous, especially the Malfoys.
How does all this exactingly correct pronunciation stuff interact with accents, speech impediments, having just been socked in the face, or otherwise having issues with getting exact sounds out?
For that matter, what do mute wizards and witches do? Do they just have to learn to cast everything nonverbally? Or can they cure muteness with magic such that it never comes up?
Eliezer previously considered the idea of a cabal of physicists keeping nuclear weapons a secret in this post. The idea turns up again in this chapter of Three Worlds Collide. Any thoughts? Would you feel safer if only super-rich physicists had access to nuclear weapons?
Is Harry learning how to lose?
Chp 19 is when Harry went through the ordeal with Quirrell to learn how to lose.
Chp 21 he lost the textbook reading contest with Hermione and acted like a whiny sore loser, suggesting that he hadn't really learned much. He acted like such a brat that I had to assume that he'd failed to learn some basic social skills in his solitary homeschooled childhood (e.g., you should at least act like you've lost gracefully, by congratulating the winner and not complaining).
Chp 32 Harry seems to be trying to goad Draco and Hermione into ...
Regarding the author's notes for chapter 32: I assume the complexity class you're looking for at the end there would be something like PromiseNP? Also, the trick really is more general than that, seeing as you can actually use it to do anything in PSPACE.
I should really have mentioned this back in the appropriate chapter, but..
Remember how Harry complains that adding (consistent) time-travel makes the universe uncomputable? Leaving aside how I'm not exactly convinced of that myself, I thought I should point out that such consistent time-travel has recently been experimentally demonstrated.
Have a look at http://arxiv4.library.cornell.edu/abs/1005.2219 . It was published way too late for Harry to read it, unfortunately. :P
...Harry's knuckles had gone white on his wand by the time he stopped trying to Transfigure the air in front of his wand into a paperclip. It wouldn't have been safe to Transfigure the paperclip into gas, of course, but Harry didn't see any reason why it would be unsafe the other way around. It just wasn't supposed to be possible. But why not? Air was as real a substance as anything else...
Well, maybe that limitation did make sense. Air was disorganized, all the molecules constantly changing their relation to each other. Maybe you couldn't impose a new form
Shouldn't Slughorn be trying to get Harry into his social circle very soon after Harry's substantial victory over Snape?
Just because I never read the original material - in Chapter 27:
"And you wanted to see the results of your test firsthand," said Harry. "So. Am I like my father?"
A strange sad expression came over the man, one that looked foreign to his face. "I should sooner say, Harry Potter, that you resemble -"
Severus stopped short.
...is the name he doesn't say Remus Lupin?
Chapter 25: Couldn't magical genes evolve if magic (call it matter being susceptible to intent) exists? Vision is a complex thing, but from one angle vision evolves because light exists.
If magic is artificial and magic genes can't evolve, this implies that all the magical species were invented.
In Chapter 6, when Harry was buying the trunk: his whole speech about planning fallacies and collaborators ... wasn't really necessary, was it? Even had he not stolen his own money, I doubt that the proprietor would have refused a down payment accompanied by a request to hold the trunk overnight, pending the remainder of the sum to be payed in the morning.
That said: what if he had simply withdrawn the eleven Galleons and presented them as a fait accompli, without preface?
That is just awesome. Made my day! While reading the story i hat to laugh out loudly on almost every third sentence, much to the annoyance of my neighbors. Thats a feat no other story has accomplished so far, not even discworld - which would be the close contender.
I was also happy to learn that i figured out the solution to Harry's sleeping problem right about when it introduced. But i didn't solve the confusing morning riddle.
Ch. 21
Where is the tentacle rape exactly? The only thing I found in the ballpark was the burbling fountain of ooze, which suggests a Shoggoth, hence tentacles and tentacle rape, but that seems really weak.
For the lazy:
...
Harry knew now how people felt when they were tired of running, tired of trying to escape fate, and they just fell to the ground and let the horrifically befanged and tentacled demons of the darkest abyss drag them off to their unspeakable destiny.
Unpack "unspeakable".
You're welcome.
Is someone who has never read any of the Harry Potter books and is not a fan of the movies likely to appreciate this work? I'm somewhat curious to read it but suspect I'd have trouble following the references.
I probably need to write up a "For those who have never seen the books" summary page of years 1-7, containing all the information that will be needed mixed with enough other information that it looks like a summary instead of "here is exactly and only what you will need to know".
I'm not complaining about story balance. I just don't enjoy this particular brand of wish fulfillment - fantasizing about a nerd that could stare down five big bullies and still stay a nerd.
I wonder if Eliezer has or should read this review of Ender's Game (a book I never read myself, but the reviewer seems to provide a useful warning to authors).
Ouch! I -- I actually really enjoyed Ender's Game. But I have to admit there's a lot of truth in that review.
Now I feel vaguely guilty...
Probably a stored rant here, but the thing that put me off most from Ender's Game (which I'd read as an adult) was that the adults con a child into pushing the button which wipes out an alien race, and with the intent of absolving themselves from responsibility. IIRC, Ender actually does accept (partial?) responsibility in a later book.
Even though I've become more cynical since I read that book, I still think the adult behavior was well outside the human range. The normal thing is to blame the aliens for humans thinking it made sense to wipe them out.
"Also the absence of anything that looked AT ALL like a bell curve distribution of ability. The battle school kids are all supposed to be massively well selected and trained, yet only Ender, Bean, Valentine and Peter really matter. "
If you select out the right end of the bell curve from the general population, then you won't have a bell curve anymore, but rather a fat lower end.
Also, the training was supposed to be a sort of abstract sport to select for leadership skill, coolness under pressure, etc - it wasn't supposed to be actually training them to fight in space. They did training of the actual spaceshippy stuff later. You could certainly argue they should have started that earlier though.
That sounds like it would work much better as a series of "In Magical Britain" jokes.
In Normal Britain, fundamental attribution is an error. In Magical Britain, all error can be attributed to someone's fundament!!
Oh, that's a necessary part of the dream. Every badass nerd must feel a little romantic remorse after gruesomely defeating the enemies. Once again, see Ender's Game, the perfect archetype of such fantasies.
Perhaps the lesson here is that an attitude of winning at all costs is something that can lead someone to seek out real rationality, (as in 'something to protect') but is a bias and a handicap when you apply it to subproblems without keeping your sub-solutions within the proper scope.
Ch. 21
Has Draco been intentionally trying to drive a wedge between Harry and Hermione because he sees that Hermione is the top peer rival for Harry's friendship, or does he just really hate Hermione and expect Harry to hate her too?
Just finished the whole thing. Would like to say I thoroughly enjoyed it all. It starts out as one thing (entirely comedy) and over time becomes darker and more serious - I was really impressed by how the transition was handled.
One tiny detail that I especially liked was that, whenever messages where time-turnered back in time, Harry always copied it onto a new piece of paper - the same piece never went around a full loop (that I noticed). As soon as you notice that you notice that a piece going around a full loop would be infinitely old, and would have already been worn out to nothingness.
I wonder what Arithmancy is in this universe (or in the original Potterverse, for that matter).
Seriously? Did you miss the part about "I think that the second degree of caution will suffice."?
When Harry did the experiment under the supervision of an experienced, adult wizard, he had all sorts of safety precautions in place, that he did not have when he tried it on his own.
Hermione was right, Harry could have gotten them killed by trying novel tricks without any sort of precautions. And having seen the standard precautions, Harry understood this, which is why:
"Um, Hermione?" Harry said in a very small voice. "I think I owe you a really, really, really big apology."
I always thought the killing curse was overrated. Many of the spells that first years use in pranks on each other will get you a kill if you are carrying a knife in your pocket.
In 1 vs 1 combat stupefy beats avada kedavra. By about 3 syllables.
Chapter 27
A lot of folks seem to make a big deal out of Harry not understanding Snape's "racist" comment. Which is very strange to me, as I had no idea it had that sort of implication (though it's obvious in retrospect), and (while I'm no expert) I'm much more familiar with the HP canon than Harry is. "Mudblood" always sounded more to me like making fun of someone for being poor.
Read up to Chapter 26, commenting on same.
I don't quite see how this takedown of Skeeter is so brilliant. Ok, she's been convinced of something that's not true, but what of it? She's written untrue things before without getting into trouble. And the nature of the story doesn't seem particularly damaging to Lucius's interests either. Harry Potter engaged to Ginny Weasley, well, so what? It seems to me that Harry and Quirrell are both being very impressed with the technical difficulty of what's been done, without particularly considering the more relevant a...
A thought: some of Voldemort's followers were from Easter Europe. I wonder what the odds that they had support from the other side of the Iron Curtain were?
Chapter 32. Arg, it's all so clear to me now. Neville is not really out of the game. Of course Harry learned the lesson that he needed to trust people, and he could trust Neville if anyone, and everyone will love Neville having a true crowning moment of awesome here.
transforming stuff would've made much more sense in many ways(more canon-compliant too) if matter transfigured would've retained imaginary bounds, thus magically nullifying the effect of pig breathing, magically produced electricity by turning depleted uranium into new fuel and all that sort of stuff.
Chapter 29 - Am I alone in considering this the worst chapter yet (that is, <=29)?
The hacked in "Bill is schizophrenic" was unpleasant. Sure EY wanted to force in a 'conspiracy theory' lesson, but I still just found it distasteful. The remainder of the chapter was just uninspiring and did nothing but reinforce my growing impression that Harry doesn't have what it takes to become an ultimate "Universe Optimising" power. I don't think all of this is due to 'still needs to learn lessons' considerations either.
Ick. I'm going to read the next couple of chapters. Most of the recent comments here have focussed on the the 30,31 chapters so I'm hoping 29 was just an unremarkable interlude.
Chapters 29 through 31: first we got Snape turning dark and dropping his mask, and now we have Quirrell winning over Hermione? Harry's in for a harder fight than he thinks.
Also, any news about that diary?
Would the Zveebe bs Revfrq already be in the sbeovqqra guveq-sybbe pbeevqbe by this point, going by canon? That seems unlikely.
Update: Please post new comments in the latest HPMOR discussion thread, now in the discussion section, since this thread and its first few successors have grown unwieldy (direct links: two, three, four, five, six, seven).
As many of you already know, Eliezer Yudkowsky is writing a Harry Potter fanfic, Harry Potter and the Methods of Rationality, starring a rationalist Harry Potter with ambitions to transform the world by bringing the rationalist/scientific method to magic. But of course a more powerful Potter requires a more challenging wizarding world, and ... well, you can see for yourself how that plays out.
This thread is for discussion of anything related to the story, including insights, confusions, questions, speculation, jokes, discussion of rationality issues raised in the story, attempts at fanfic spinoffs, comments about related fanfictions, and meta-discussion about the fact that Eliezer Yudkowsky is writing Harry Potter fan-fiction (presumably as a means of raising the sanity waterline).
I'm making this a top-level post to create a centralized location for that discussion, since I'm guessing people have things to say (I know I do) and there isn't a great place to put them. fanfiction.net has a different set of users (plus no threading or karma), the main discussion here has been in an old open thread which has petered out and is already near the unwieldy size that would call for a top-level post, and we've had discussions come up in a few other places. So let's have that discussion here.
Comments here will obviously be full of spoilers, and I don't think it makes sense to rot13 the whole thread, so consider this a spoiler warning: this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series. Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.
A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted. This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.
