I would speculate that there's some physiological component involved in spellcasting ability that grows with age, in much the same way that older children are often more coordinated and stronger than younger children. I have no evidence to back this up other than the repeated mentions of 'age matters with spells', however.

0Lu93
It is practice. Why is, pardon, why was Hermione so much better in spells then others? Because of practice. Other children do not practice as much as Harry, or as much as Hermione did... It was somewhat suggested in part where Harry and Draco talk about muggle-borns, pure-bloods and magic.

(Note: I haven't checked yet to see if 1033 is prime)

So... basically, it's the standard Newcomb's problem, one box or two, one boxing means it's a prime number and two boxing means it's a composite number being displayed for the lottery, in this singular case.

I'd still probably one box here. If 1033 is prime, and I two box... well, then, Omega probably wouldn't have picked it and we wouldn't be discussing this scenario.

Put another way, I don't see how the lottery number matching Omega's number gives me any useful information about Omega's accuracy, since the value of one number in no way depends on the other.

I don't belong to a gym, so I won't comment on changing norms, but as far as the tone of this post goes, I have some trouble distinguishing this between "tongue firmly in cheek" and "condescending mockery". I suspect it would be easier to tell if I knew you better.

The Handbook of Chemistry and Physics?

But seriously, I have no idea either, other than 'eyeball it', and I'd like to see how other people answer this question too.

Skeeve00

That was originally where I was going with that, but further evidence of Harry's plan (the lack of any use of time-turning until at least six hours after the fact) has pretty well falsified my prediction.

0Decius
Next easiest: Harry goes back 5 hours, sends a note to original Harry explaining exactly what he has to do to save Hermione; original Harry does the heroics, including setting up a fake death and writing the directions he got, while future Harry executes the actions in the chapter, failing to prevent the death. There's a maneuver somewhere in there where future Harry then snaps his fingers, goes back one hour, and somehow initiates the course of events described (probably by blackmailing time). The theories have now gotten more unlikely than that Harry got the timey-wimey ball and is prohibited by an unstated rule from preventing a plot event.
Skeeve60

Prediction: Harry will attempt to learn Obliviation, use his Time-Turner to go back to before, and attempt to mess with his own head to save Hermione while preserving his own experience of events.

This is more likely to not work than work.

1Decius
There are too many principals who interact with Harry afterwards for that explanation to be the easiest unless the story we have read is the False Memory that Future Harry implanted in his prior self after he shoved causal theory into a refrigerator and dropped it into Puget Sound.
Skeeve150

Of course, she probably wouldn't have believed him able to not give in to the temptation, and it's hard to say whether she would have been right at that exact moment in time.

Considering that she was reacting to the signs of time-turner addiction, a phenomena that had been observed in others before, I think it was a safe assumption for McGonagall to make.

Skeeve10

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.

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 is... (read more)

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.
Skeeve110

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?

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.
Skeeve10

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.

Skeeve70

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.

Skeeve70

I think that in the aftermath of Hermione's death, Harry's breaking the rules and leaving the Great Hall is barely even going to be a blip on the radar. I'd be surprised if McGonagall even brings it up. It seems too callous for her.

Skeeve60

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.

Skeeve00

If the Patronus that came back was Future-Harry's Patronus, then what happened to Present-Harry's Patronus? When Harry's Patronus was countered with Quirell's Killing Curse in Chapter 54, Harry definitely felt it being countered.

0Dreaded_Anomaly
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.
Skeeve10

From Chapter 56:

Bellatrix was still transparent within the Cloak, but to Harry she was no longer hidden, he knew that she was there, as obvious to him as a Thestral.

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. And I suppose that obscuring the real Hermione from Harry would make sense under the 'if you want to change the past, you can't know if you've already succeeded' rule, from the end of 76.

Skeeve110

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

This bothered me as well. It's a mysterious phenomenon that directly relates to Harry's own mental state. He should have been all over that.

2Tripitaka
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.
Skeeve160

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.

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.

Skeeve50

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

Harry, feeling disassociated from himself? No; a few seconds later we have

"Fire and acid!" Harry shouted. "Use fire or acid!"

Disassociated-Harry shows up later, I think, but that first call doesn't seem to be Harry's.

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.
Skeeve170

When asked to find Hermione, why would Harry's Patronus have found a simulacrum instead of the real one?

-1Dreaded_Anomaly
The Patronus that came back to Harry could be Future-Harry's Patronus, if time travel is involved. Note: I don't personally place a high probability on theories involving time travel in this instance, but they do present a possible explanation for that objection.
3Alsadius
Because the real Hermione was under an invisibility cloak ten feet away. (Not saying this is how it happened, but it does explain that part of the riddle)
Skeeve00

Not yet, but that would seem to be a plausible end-game for Quirrelmort.

For this reason, I've found it's very important to be careful not to assume that the world is doing sensible things or giving me all the information.

Yeah, this is good advice in general, and it's definitely what I was doing wrong this time.

1Epiphany
Thanks for taking a moment to let me know that my comment is appreciated and that this information makes a difference for you. I find that, like Luke says in The Power of Reinforcement, knowing that a behavior of mine has made a difference and is wanted "increases the probability that the behavior will occur again". I think LessWrong could really use more positive reinforcement, so I hereby positively reinforce you for showing the humility to positively reinforce.
Skeeve60

Well, yes, but what does 2% failure rate per year even mean when it's presented independent of a number of uses per year? I mean, without knowing what number of average uses were used to calculate "2% failure rate per year", it seems like somewhat of a misleading statement, as I'm reasonably certain (let's say at least 90%) that it's not intended to reflect that condoms become more protective the more chances you have to use them.

I feel like I'm missing something basic here that would let me see why it's a useful piece of information on its own.

1A1987dM
I agree it's misleading. That's why I'd prefer a metric like this, where the precise definitions you use don't matter if they are the same in both the numerator and the denominator as constant factors would cancel out.
2Epiphany
This is a good observation. You can look up what the average number of uses per year is. If I remember right, I've seen some condom efficacy studies include that information. You're not missing anything basic, you're correctly perceiving ambiguity where ambiguity does exist. Even when information is really important, I've found that it's often been omitted simply because products are marketed to the average person, not to nerdy people like me, and most people don't want to think as much as I do. For this reason, I've found it's very important to be careful not to assume that the world is doing sensible things or giving me all the information. They're not just leaving information out, they're also not being held accountable by a world full of people who think as much as I do. Therefore, they can get away with slapping various nonsense marketing claims and out-of-context data on their boxes without people questioning them.
Skeeve00

That's what I assumed as well, that it was 2% per incident, but I'm having a little trouble parsing those differently:

How is 2% per incident different than 2% per year? I'd interpret both of those statements as 'on average, given perfect use, a condom will be ineffective at preventing pregnancy in one use out of fifty'.

-1mwengler
Well if you have sex once per year, it is not different. My condolences.
1Epiphany
Here's how 2% per incident is different: Let's say, hypothetically speaking, that the average number of uses per year is 100. A 2% per incident risk will add up to a yearly 50% risk for the average user.* A 2% per year risk already included 100 uses, so it is still 2% per year. A 2% per year risk would add up to a 70% chance over the 35 or so years women are fertile and active and a 2% per incident risk would add up to a much, much higher risk, likely resulting in multiple pregnancies.* * This is only if pure math reflects reality, which it probably doesn't because there are other factors here like people forgetting important parts of the instructions over time, people getting better at using them over time, or people becoming sloppy about applying them because they're tired of them or have developed a sense of over-confidence.
4A1987dM
I guess the average condom user uses more than one per year.

Speaking from the point of view of someone who wasn't previously completely sold on cryonics, this is a very thought provoking read.

As a brief tangent, I'm a little dismayed at the number of comments on that article that basically boiled down to 'it was too long to read'.

You'd think BuzzFeed was primarily a source of Internet brain candy with the readership that attracts or something.

Skeeve20

I wouldn't one-box at 1:1.01 odds; the rule I was working off was: "Precommit to one-boxing when box B is stated to contain at least as much money as box A," and I was about to launch into this big justification on how even if Omega was observed to have 99+% accuracy, rather than being a perfect predictor, it'll fail at predicting a complicated theory before it fails at predicting a simple one...

...and that's when I realized that "Precommit to one-boxing when box B is stated to contain more money than box A," is just as simple a rule that lets me two-box at 1:1 and one-box when it will earn me more.

TL;DR - your point is well taken.

Skeeve10

You might as well precommit to one-box at 1:1 odds anyway. If Omega has ever been observed to make an error, it's to your advantage to be extremely easy to model in case the problem ever comes up again. On the other hand, if Omega is truly omniscient... well, you aren't getting more than $1,000 anyway, and Omega knows where to put it.

4Pentashagon
If there is visibly $1,000 in box A and there's a probability 0 EU(one-boxing), unless one is particularly incompetent at opening boxes labelled "A". Even if Omega is omniscient, I'm not, so I can never have p=1. If anyone would one-box at 1:1 odds, would they also one-box at 1:1.01 odds (taking $990 over $1000 by two-boxing) in the hope that Omega would offer better odds in the future and predict them better?
Skeeve40

I agree with you; the context from earlier in the strip was about reading a study with evidence pointing to T-rexes being a timid scavenger, and then getting transported back in time and seeing a T-rex acting timid.

Skeeve30

The secret is to make wanting the truth your entire identity, right. If your persona is completely stripped down to just "All I care about is the facts", then the steps disappear, the obstacles are gone. Tyranosaurus was a scavenger? Okay! And then you walk right up to it without hesitation. The evidence says the killer was someone else? Okay, see you later sir, sorry for the inconvenience, wanna go bowling later now that we're on a first name basis? And so on. Just you and a straight path to the truth. That is how you become perfect.

Skeeve110

My wife and I have decided we're going to homeschool our son, almost five, for various reasons. What age do you think it would be appropriate to start rationality training, and how would you go about it? Are there any particularly kid-friendly resources on rationality that anyone can recommend? (The sequences are good for beginners, but they're well above the level of a five year old).

7ChristianKl
You might want to look into the idea of unschooling. Certainly before they reach five. (1) Kids want parents to do stuff. Most parents rely on their authority and don't give their kid what it wants, even if the kid is able to provide valid reasons. A good way to teach rationality is to avoid to rely on arguments by authority. My father had the policy of always giving me the real reason when I asked for something whether or not I would be able to fully understand the answer. That taught me that it's okay to get answers to questions that I don't understand. It was a valuable lesson for me. Dumbing things down and relying on authority for arguments are the two biggest things that parents do to avoid their children being rational. (2) When it comes to giving out pocket money consider giving it out as betting money. Let's say the allowance is $3 per week. Whenever the kid disagrees with you about a factual matter, he's allowed to ask you for your odds. So the kid thinks it's raining. You don't think so and are pretty certain. So you say you have 4:1 odds. The kid can bet $1 from his betting money. If he wins the bet than he get $4 in real coins from which he can buy something. The pocket money is motivating so he will have a huge incentive to get good at having accurate confidence in his beliefs. After a while he might even give you some rationality lessons. (3) I would think about teaching a five year old Anki for all occasions where he has to learn something.
7Shmi
Now would be good? You can probably construct appropriate questions for a five-year-old based on the Eliezer's version of the fundamental question of rationality: "Why do you believe what you believe?". This can apply to a playground fight as much as to a big political issue.

That sounds a bit like muddling the hypothetical, along the lines of "well, if I don't let my family be tortured to death, all those strangers dying would destabilize society, which would also cause my loved ones harm". No. Consider the death of those strangers to have no discernible impact whatsoever on your loved ones, and to keep the numbers lower, let's compare "x strangers tortured to death" versus "wife and child tortured to death". Solve for x. You wouldn't need to watch the deeds in both cases (although feel free to say what would change if you'd need to watch when choosing against your family), it would be a button choice scenario. The difference between myself and many others on LW is that not only would I unabashedly decide in favor of my loved ones over an arbitrary amount of strangers (whose fate wouldn't impact us), I do not find any fault with that choice, i.e. it is an accurate reflection of my prioritized values. As the saying goes, "if the hill will not come to Skeeve, Skeeve will go to the hill". There's a better alternative to trying to rewrite your values to suit your self-image. Which is constructing an honest self-image to reflect your values.

1) I find that interacting with other people face-to-face is mentally exhausting for me. A few hours or so of prolonged exposure is not so bad, but more than that and I have to exert noticeable effort to not be snappish and crabby with people.

Skeeve30

I don't think I was having any trouble distinguishing between "would", "should", and "prefer". Your analysis of my statement is spot on - it's exactly what I was intending to say.

If morality is (rather simplistically) defined as what we "should" do, I ought to be concerned when what I would do and what I should do doesn't line up, if I want to be a moral person.

Skeeve20

What I mean by 'immorality' is that I, on reflection, believe I am willing to break rules that I wouldn't otherwise if it would benefit my family. Going back to the original switch problem, if it was ten people tied to the siding, and my wife and child tied to the main track, I'd flip the switch and send the train onto the siding.

I don't know if that's morally defensible, but it's still what I'd do.

6ArisKatsaris
I'm finding myself disappointed that so many people have trouble distinguishing between "would" "should" and "prefer" You're just saying that a) you'd prefer to save your family b) you believe you would save your family. c) you probably should not. There's nothing at all contradictory in the above statements. You would do something and prefer to do something that you recognize you shouldn't. What you "prefer" and what you "would" and what you "should" are all different logical concepts, so there's no reason to think they always coincide even when they often do.
0Petruchio
I can see that. It will be a difficult choice, but I would do the same. I think it is morally defensible. [Edit] On second thought, I am not a husband or father, but I would like to think I will one day have a family who has heroic virtue enough to be willing to sacrifice their live for others. How I would behave, again is subject to my emotions, but I would like to honor that wish.
Skeeve50

I find myself thinking mostly around the same lines as you, and so far the best I've been able to come up with is "I'm willing to accept a certain amount of immorality when it comes to the welfare of my wife and child".

I'm not really comfortable with the implications of that, or that I'm not completely confident it's not still a rationalization.

2Kawoomba
Is there an amount of human suffering of strangers to avoid which you'd consent to have your wife and child tortured to death? Also, you're "allowed" your own values -- no need for rationalizations for your terminal values, whatever they may be. If the implications make you uncomfortable (maybe they aren't in accordance with facets of your self-image), well, there's not yet been a human with non-contradictory values so you're in good company.
-3MugaSofer
As a non-parent, I endorse this comment.
-1Petruchio
What is immorality then? Even a theist would say "morality is that which is good and should be done, and immorality is that which is not good and should not be done." If you think it would be immoral to spare you wife and child, then you are saying it is not a good thing and shouldn’t be done. I am pretty sure protecting your family is a good thing, and most people would agree. The problem is, I think, is not that it is immoral to not push you wife and child in front of a moving train, albeit to save 5 others, but that it is immoral to push any individual in front of a train to save some other individuals. If you increase the numbers enough, though, I would think it changes, since you are not just saving others, but society, or civilization or a town or what have you. Sacrificing others for that is acceptable, but rarely does this require a single person’s sacrifice, and it usually requires the consent and deliberation of the society under threat. Hence why we have the draft.

My own anti-procrastination technique is to tell my wife that I'm going to be working on X project, and that I'll talk to her about what I've been doing when I'm done. After that, I find that all it takes to put myself back on task is a gentle reminder to myself that my options are:

  • Get some work done
  • Admit that I didn't actually get much done
  • Lie about my progress

My natural aversion to options two and three is usually enough to get me back on task.
