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.

Sounds like you worry a lot more about status than I do. o_O
Sounds like he's male. A while ago, I read something in a thread on reddit about women in IT, where a woman complained about women having to prove themselves all the time there. And I was thinking that yes, that sucks; you'd think that after a time, people would recognize that hey, this woman knows her stuff. But then a man asked what was the problem with that, after all, it wasn't like men didn't have to prove themselves with every interaction as well.
