Follow-up to: Boring Advice Repository
Many practical problems in instrumental rationality appear to be wide open. Two I've been annoyed by recently are "what should I eat?" and "how should I exercise?" However, some appear to be more or less solved. For example, various mnemonic techniques like memory palaces, along with spaced repetition, seem to more or less solve the problem of memorization.
I would like people to use this thread to post other examples of solved problems in instrumental rationality. I'm pretty sure you all collectively know good examples; there's a comment I can't find from a user who said something like "taking a flattering photograph of yourself is a solved problem," and it's likely that there are other useful examples like this that aren't common knowledge. Err on the side of posting solutions which may not be universal but are still likely to be helpful to many people.
(This thread is allowed to not be boring! Go wild!)
I don't want to speculate about EY other than saying my model of him didn't expect to ever see "too complex" brought up as a reason not to try anything. Maybe there's too much overlap with HPMOR:Harry. It is possible that there are individuals whose akrasia levels / mental energy and self-image are unaffected by being overweight compared to not being overweight. Just unlikely.
That's true, but doesn't change that ceteris paribus given little exercise, you'll still live longer not being obese. Note that I've not even mentioned exercise. It's certainly better being overweight and exercising (while still being overweight), than being overweight and not exercising.
You're reading "too complex" as "difficult" but eliezer means it as "something with inherently low priors for working".
