That's a good point, but I'm still not convinced.

Hugging is, potentially, fast: if A tries to hug B and B pulls away, a hug has still occurred. Sex takes longer: there's complicated steps involving disrobing and so forth. Your argument applies to, say, groping; but if B doesn't want to cooperate then that becomes relevant before sex has occurred. It's clear ("safe", "take matters into her own hands") that there is not a reliable way of getting out of sex.

Also, the dialogue ("Prohibition", "too much") seems to suggest social acceptance.

Well, part of it is that Quirrel is Voldemort in canon, which is significant evidence that Harry doesn't have.

0gwern
There's tons of evidence in-universe; even if he shouldn't suspect by chapter 20, then by ch100 the failure has become impossible. (And I recall that knowing about canon was actually a problem for a lot of people: "surely it can't be that obvious? Eliezer would never take such an obvious tack!")
Pavitra10

I don't think it's a good idea to do a formal memorization of something that's not based on any kind of scientific research.

0MalcolmOcean
Ehh, I've gotten a lot of value out of memorizing poems, and even definitions. I don't do many of the latter, but I've found that throwing a word in Anki usually causes me to have it available as a concept later, which is often helpful.
Pavitra240

Part of that seems to be from HPMOR. I'm not sure where the rest comes from.

9Dentin
Yeah, almost certainly HPMOR inspired. Eliezer's work has spread far.
Pavitra00

On the other hand, one should consider not only what was said, but also what should have been said.

Pavitra00

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.

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.)

3Sheaman3773
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.
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-ba

Nice job!

Some of the horcruxes in canon are made from murdering Muggles, though. I don't see anywhere that this happens in Chapter 45.

Well spotted.
0buybuydandavis
I think Voldemort sets himself up to move from host to host, and who better to move into, than the hero who saves the world from Voldemort?
Pavitra40

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.
Pavitra10

Just because $CELEBRITY uses it that way doesn't make it right. This usage is conflating two usefully distinct concepts.

Pavitra50

It's only testable in one direction -- if you like, "never" is testable but "ever" isn't. I don't have a formal argument to hand, but it seems vaguely to me that a hypothesis preferably-ought to be falsifiable both ways.

Pavitra30

The story is, in large part, about the structure of the story: Pluto's tragic flaw is that he's thinking about his real life in terms of story structure.

Pavitra80

Consider the epistemic state of someone who knows that they have the attention of a vastly greater intelligence than themselves, but doesn't know whether that intelligence is Friendly. An even-slightly-wrong CAI will modify your utility function, and there's nothing you can do but watch it happen.

0DanielH
An even-slightly-wrong CAI won't modify your utility function because she isn't wrong in that way. An even-slightly-wrong CAI does do several other bad things, but that isn't one of them.

Not really relevant here, but I only just now got the pun in CFAR's acronym.

I'm from the future. Thanks for telling me this. I hadn't realized this despite seeing the name for years.

You may be right, but I don't trust a human to only arrive at that conclusion if it's true. I think we ought to refrain from pressing D, just in case.

Depending on how smart I feel today, anywhere from -10 to 40 decibans.

(edit: I remember how log odds work now.)

Pavitra00

I think a more plausible scenario for the atomic theory being wrong would be that the scientific community -- and possibly the scientific method -- is somehow fundamentally borked up.

Humans have come up with -- and become strongly confident in -- vast, highly detailed, completely nowhere-remotely-near-true theories before, and it's pretty hard to tell from the inside whether you're the one who won the epistemic lottery. They all think they have excellent reasons for believing they're right.

Pavitra110

You are way overconfident in your own sanity. What proportion of humans experience vivid, detailed hallucinations on a regular basis? (not counting dreams)

9fubarobfusco
Oh, sure — that I'm hallucinating something is much more likely.
Pavitra00

The original question was:

Do you really think encouraging this idea in general is good?

That is: assuming it is possible to reduce bad uses at the cost of also reducing good uses, should one do so?

Your reply seems to assume that the bad uses can't be reduced, which contradicts the pre-established assumptions. If you want to change the assumptions of a discussion, please include a note that you are doing so and ideally a short explanation of why you think the previous assumptions should be rejected in favor of the new ones.

0Desrtopa
I don't assume that bad uses can't be reduced, and my answer is somewhat tongue in cheek, but I do suspect that getting people to stop using this mode of thought for bad ideas would be very difficult. Getting people to apply it to good causes as well might be worse, outcome-wise, than getting them to stop applying it all, but trying to get people to apply it to good causes might still have a better return on investment than trying to get them to stop, simply because it's easier.
Pavitra30

So it's a great idea as long as only causes you agree with get to use the superweapon?

Desrtopa100

Well, if you can't stop people from using a superweapon for bad causes, it may be an improvement to see to it that it's also used for good causes.

Pavitra-20

Can you guarantee that a TSPO wouldn't see epiphenomenal consciousness?

-2MugaSofer
Well, no. How is that different from epiphenomenal spaceships? Our modal predicts spaceships but no p-zombies.
Pavitra30

I vaguely object to the common practice of soliciting responses, and implying that the results will/may be meaningful, without simultaneously precommitting to a particular mapping of raw results to inferred meaning. (The precommitment can be done while keeping the mapping secret, by using a hash algorithm.)

Recall that the goal isn't to undershoot reality every time, but to do so half the time.

assuming symmetry and some relation to a linear component of your utility fuction, and so on...

Pavitra20

Unfortunately, if there is disagreement merely about how much prior uncertainty is appropriate, then this is sufficient to render the outcome controversial.

3jsalvatier
I think your initial point is wrong. There are 3 situations 1. Clear prior info: Bayes works well. 2. Controversial prior info, but posterior dominated by likelihood: Choose weak enough priors to convince skeptics. Bayes works well. 3. Controversial prior info, posterior not dominated by likelihood: If you choose very weak priors skeptics won't be convinced. If you choose strong priors skeptics won't be convinced. Bayes doesn't work well. Frequentism will also not work well unless you sneak in strong assumptions.
Pavitra10

My general impression is that Bayes is useful in diagnosis, where there's a relatively uncontroversially already-known base rate, and frequentism is useful in research, where the priors are highly subject to disagreement.

0jsalvatier
You can also do Bayesian analysis with 'non-informative' priors or weakly-informative priors. As an example of the latter: if you're trying to figure out the mean change earth's surface temperature you might say 'it's almost certainly more then -50C and less than 50C'.
4Manfred
Why this isn't necessarily true: If we look at Bayes' theorem (that picture above, with P(A|B) pronounced "probability of A if we learn B"), our probability of A after getting evidence B is equal to P(A) before you saw the evidence (the "prior probability"), times a factor P(B|A)/P(B). This factor is called the "likelihood ratio," and it tells you how much impact the evidence should have on your probability - what it means is that the more unexpected the evidence would be if A wasn't true, the more the evidence supports A. Like how UFO abduction stories aren't very convincing, because we'd expect them to happen even if there weren't any aliens (so P(B|A)/P(B) is close to 1, so multiplying by that factor doesn't change our belief). Anyhow, because Bayes' theorem can be split up into parts like this, research papers don't have to rely on priors! Each paper could just gather some evidence, and then report the likelihood ratio - P(evidence | hypothesis)/P(evidence). Then people with different priors would just multiply their prior, P(A), by the likelihood ratio, and that would be Bayes' theorem, so they would each get P(A|B). And if you want to gather evidence from multiple papers, you can just multiply them together. Although, that's only in a fairy-tale world with e.g. no file-drawer effect. In reality, more care would be necessary - the point is just that differing priors don't halt science.

How about an expanded version: if we could be a timeless spaceless perfect observer of the universe(s), what evidence would we expect to see?

I suspect that the answer to the alien-ball case may be empirical rather than philosophical.

Suppose that there existed quantum configurations in which the alien threw in a red ball, and there existed quantum configurations in which the alien threw in a blue ball, and both of those have approximately equal causal influence on the configuration-cluster in which we are having (approximately) this conversation. In this case, we would happen to be living in a particular type of world such that there was no fact of the matter as to which color ball it was (except that e.g. it mostly wasn't green).

Pavitra10

My first reaction is that this would increase the expected cost of revival, for the same reason that it's harder to get plane tickets if you're in a group that wants to sit near each other.

0DataPacRat
I'm not quite sure I follow your reasoning; would it be possible for you to try rephrasing what you mean?
Pavitra50

That is a valid line of reasoning that arrives at the same conclusion, but it's not the reasoning put forth in the fic.

5Alicorn
The sex change alone does suffice, and the line of reasoning used in the fic would make no sense if the character's sex were not new.
Pavitra50

I started reading this fic, and... we need to talk.

In chapter 2, the protagonist tries to think through the practical implications of being female. The result is one of the worst examples I've seen of male nerd cluelessness about women, to the point that I would have sooner expected to see it as a satire than as a real example.

Lest anyone who hasn't read the fic think I'm exaggerating, the offending paragraph runs as follows:

Oh, come now; if I suddenly acquired new sex-related complications on the order of being able to get pregnant, and I was also a new species, I'd probably want to avoid that for at least a while.

And also has much more on her mind than figuring out how to get laid, let alone with species she's never considered fornicating with - and ... (read more)

For strength, you use Dugbogs that were crushed by a strong Re'em.

For heat, you use bronze that was forged in a hot forge.

For immortality, you use a corpse that was burned by an immortal phoenix.

2Sheaman3773
Speaking in terms of significance: The Dugbogs were not crushed by a strong Re'em, but by a Re'em's strength. The strength was used to crush them, and the strength was what you got out of it. The knuts were not forged by a hot forge, but by the forge's heat. The heat was used to forge them, and the heat was what you got out out it. In your scenario, the immortality of the phoenix was not used to burn the corpse, so you cannot get immortality out of it.
0chaosmosis
K. I was confused because Bellatrix hadn't died, mostly. Your edit helped.
Pavitra00

There's not (last I checked) a community consensus on the issue, and I'd rather isolate the meta-discussion to its own thread, rather than splattered all over anywhere Alicorn posts a comment.

An ignore feature would indeed be a significant improvement. I'm not convinced that it's strictly necessary or sufficient, but I do think that it would be better to do than not.

Pavitra30

The votable texts on Fimfiction are generally much longer, so one is less likely to pay attention to a thing unless one already expects it to be worth reading.

Perhaps I'm overestimating human nature, but Lars reads to me like an outgroup stereotype.

wedrifid260

I doubt that a rogue moderator would receive express advance approval of abusive actions. If Eliezer says that Alicorn may ban certain comments, then it is not abusive for Alicorn to ban those comments.

If Eliezer's approval makes the action tautologically non-abusive then please act as if I substituted a different word that means something along the lines of "detrimental, innapropriate, politically ill advised, deprecated and considered 'naughty' by user:wedrifid". ;)

Pavitra00

Citation needed. This sounds plausible enough that people are likely to listen to it, so I'd like some sort of confirmation that it's based in fact.

4Alicorn
I have an autism diagnosis and multiple autistic friends. I poked around the literature on autism for a paper in grad school (although it was mostly on theory of mind). I have read books and blogs and aggregated therefrom a general model of autism that has yet to be dinged by any of this. Also, "don't do things to people that they find abhorrent for no goddamn reason" and "if someone never makes eye contact anyway their rocking is insignificant information about whether you have their attention, and rocking is only atypical, not fundamentally different from pen-twirling" and "one thing to try if giving someone an instruction doesn't work is making sure they have it taskified; also don't expect giving the people around you commands to work all the time" all seem pretty basic to me. And really ought to be status-quo, requiring citations to deviate therefrom. I would certainly require a citation if I had a kid and someone told me that they should be forced into contact with objects they don't like, and aren't to be allowed to move around as they please even if they aren't hurting anyone, and that their not doing everything I say is a sign of a Serious Problem. The allistic equivalents would be unambiguous abuse, and plenty of autistic people are capable of telling others what the autistic-specific versions of those abuses are.

Under the potion conservation rule, creating an Elixir of Life would require inputting some sort of immortality. Fawkes killed Narcissa to create an Elixir ingredient.

Edit: I'm an idiot.

0chaosmosis
The Sorcerer's Stone isn't a potion. The immortality has to come from somewhere, and it's just as likely that it's produced by the stone as it is that it's produced by one of the stone's components. I don't know what this sentence means.

Assuming our MMS-prior uses a binary machine, the probability of any single hypothesis of complexity C=X is equal to the total probabilities of all hypotheses of complexity C>X.

Pavitra50

Yes. However, since the point of the game is to display beliefs that you hold and others don't, you should choose the phrasing that makes your confidence higher than LW's. That is: if you think other LWers are 5% confident of X, then you should say you're 10% confident of X; and if you think other LWers are 15% confident of X, then you should say you're 90% confident of not-X.
