Feeling of powerlessness - tiring.

Fear of suffering if you choose wrong (plus bonus regret), inability to gather info enough to ensure outcome - tiring.

Feeling of scarcity - that you can't just lock in some "if it turns out I'm wrong, I win anyway, I have this insurance ..." security, but instead must really bear an emotionally crushing loss - tiring.

Is an omnipotent omniscient tired out by decisions? No.

Comment by jonathan_graehl on What are reliable ways to make a statement in such a way that I will be able to prove in the future that I had made that statement? · 2019-04-24T18:53:48.590Z · score: 6 (4 votes) · LW · GW

Proving you made the statement at a given time is as simple as getting a trusted signed timestamp or inserting it in some blockchain-like ledger, but that's not even close to making yourself accountable for predictive accuracy.

Be sure to publish *all* your predictions so we don't get file-drawered (except on you as a person which we probably can't help).

A common technique is to publish a secure hash of your prediction rather than the text (in case you want to avoid it being self-fulfilled or anti-fulfilled or otherwise traded on) (crypto signed w/ your identity, too).

But if we don't see a stream of plaintext reveals and a means of identifying all such hashes you've published, we might suspect you of planting both positive and negative predictions.

Most people prefer to publish their prediction (+reasoning) clear-text because they want to persuade and they want credit for being smart before the verdict is in.

Comment by jonathan_graehl on What are effective strategies for mitigating the impact of acute sleep deprivation on cognition? · 2019-03-31T21:48:43.248Z · score: 4 (4 votes) · LW · GW

Sleep deprivation is cumulative over the span of weeks. Being short 30 min each day for two weeks is disastrous. Almost no one is near top capability with even 7 hours. Memory formation and recall are especially limited on low sleep, even if you drug to overcome the lapses in attention. Physical health is also severely harmed (look at how attractive someone is after 'beauty sleep' vs deprived), perhaps mostly via poor diet choices but honestly why would evolution not layer on physical garbage collection processes when mental ones are already underway ... further, a bunch of micro naps doesn't give you the same concentration of deep sleep as the last 3 hours of an 8.5 hour bout would (8.5 is my ideal; 8 is tolerable).

Yes, that's suspicious. Good instinct. I'm sure there's some bias against publishing a marginally-significant result that's got a low (outside the framework of the paper's statistical model) prior. I'd bet some of the unlucky ones got file-drawered, and others (dishonestly or not) kept on collecting more data until the noise (I presume) was averaged down.

However, you might be missing that on an iso-P contour, false positives have diminishing effect size as sample size increases.

Thanks for answering that as if it were a sincere question (it was).

"Maybe this universe has invisible/anthropic/supernatural properties" is a fascinating line of daydreaming that seems a bit time-wasting to me, because I'm not at all confident I'd do anything healthy/useful if I started attempting to experiment.

http://www.youtube.com/watch?v=joZV0XARmvA - "Is Amanda Knox Guilty?" - NBC produced docu for BBC.

Summary: Guede might be guilty (I don't know), Knox+Sollecito lied to try to get out of trouble, there's interesting DNA evidence with severe technical problems:

  1. a lot of DNA from Solecito (likely making him the one who handled it) on a bra clasp that wasn't collected from the scene until 46 days later. Unfortunately by then there was plenty of incentive by then for authorities to falsify evidence to bolster their extremely weak case.

  2. A tiny trace of Kercher's DNA on a knife in Solecito's apartment - also collected after incentive to falsify (they cheated by running the test when they weren't supposed to due to insufficient amount of material, at the very least).

  3. faint bloody footprints of the right size in the bathroom. not strong evidence of killing and apparently might not even be blood (they didn't collect any, just have illuminator dye photos which can trigger off bleach too).

The rest seems like comparatively unreliable evidence to me. DNA of you, even drops of blood, in your own bathroom? Big deal. Accusations from the convicted killer (Guede)? People pressured by police lied to try to get out of trouble? No surprise. I believe ~90% that neither Knox nor Sollecito killed her or helped cover the killing. Most concerning to me are the reasons given by the authorities - it's mostly pretty lame ("there must have been 3 attackers! there weren't many defensive wounds! kercher knew karate! not even superman could do that alone. and amanda covered her ears!")

from the perspective of 100,000,000 years later it is unlikely that the most critical point in this part of history will have been the distribution of enough malaria nets

I read this as presuming that generating/saving more humans is a worse use of smart/rich people's attention and resources than developing future-good theory+technology (or maybe it's only making more malaria-net-charity-recipients and their descendants that isn't a good investment toward those future-good things, but that's not likely to figure, since we can save quite a few lives at a very favorable ratio).

I wonder if you meant that it's a worse use because we have more people alive now than is optimal for future good, or because we only want more smart people, or something else.

We should unpack "banish talk of X" to mean that we should avoid assessments/analysis that would naturally be expressed in such surface terms.

I have genuine uncertainty as to the nature of farmed chicken suffering - enough that I'd say it's bad to create your average meat-farmed chicken - otherwise I'd be right there with you at 10^20 or something similarly ridiculous.

The suggestion to genetically engineer suffering-knockout chicken seems a good one (though I'd have some residual uncertainty even then).

I don't know about you, but my explanation for being leery is: what Facebook groups do I expect to encounter? Answer: those that devote a large amount of effort to promoting themselves. (I also expect to encounter Facebook groups that are popular/worthy, but note that the anthropic reason I gave first applies no matter whether the group is actually good). Be skeptical of things that come to your attention through Facebook - at least beware privileging the hypothesis.

I agree that awareness promotion can be good, but another instinct tells me that Facebookers love to conclude that the best thing they can do is share/like/etc. - it's like finding the cheapest way possible to feel like a good person.

Do you think factory-farmed-chicken-lives are worth living? That is, if you could create infinitely many of them at no material cost would you do so?

Ignoring economic/environmental cost, how many chickens would you create and breed into factory-farming suffering, in exchange for one additional QALY? That is, you wouldn't make the trade unless it took fewer than this number of farmed chickens.

[pollid:544]

(answers may be very small (less than 1) if you value avoiding chicken suffering more than healthy human life-years) or even negative if you'd give up human lives to create more suffering chickens.

(If you think factory-farmed chickens have lives worth creating, please don't answer the poll, as your answer of infinity will throw off the average - you can vote "yes" or "indifferent" to the poll below this instead; this poll is mostly for people who answer "no" to it)

(I don't claim that chickens can actually be traded for human QALY - I still haven't gotten the ritual exactly working yet).

I'm pretty humble about what I know. That said, it sometimes pays to not undersell (when others are confidently wrong, and there's no time to explain why, for example).

Interesting analogy between "best path / MAP (viterbi)" :: "integral over all paths / expectation" as "consistent" :: "some other type of thinking/ not consistent?" I don't see what "integral over many possibilities" has to do with consistency, except that it's sometimes the correct (but more expensive) thing to do.

But I've been able to cultivate caring about particular goals/activities/habits, and then, with respect to those, I'm not so lazy - because I found them to offer frequent or large enough rewards, and I don't feel like I'm missing out on any particular type of reward.

My personal answer:

  1. I'm smart. They're not (IQ test, SAT, or a million other evidences). Even though high intelligence doesn't at all cause rationality, in my experience judging others it's so correlated as to nearly be a prerequisite.

  2. I care a lot (but not too much) about consistency under the best / most rational reflection I'm capable of. Whenever this would conflict with people liking me, I know how to keep a secret. They don't make such strong claims of valuing rationality. Maybe others are secretly rational, but I doubt it. In the circles I move in, nobody is trying to conceal intellect. If you could be fun, nice, AND seem smart, you would do it. Those who can't seem smart, aren't.

  3. I'm winning more than they are.
