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!)
Eliezer has mentioned many of the things he has tried to lose weight (including ketogenic diets and even clenbuterol). I've tried all those he has mentioned. The difference is for me they work (I call it 'cutting' and can merrily play around with my body composition all sorts of ways). But if, like Eliezer, I had expended huge amounts of effort and my body did not respond significantly then I would update my expectations.
Things that are expected to fail have low expected value. Sometimes you need to shut up and multiply instead of shut up and do the impossible.
Expected value calculations. Unless you are making accusations of lies---outright fabrication of self reports.
For the purpose of declaring an accusation of irrationality false the relevant point of view is Eliezer's. If Eliezer had someone else's values then it would make sense to evaluate the rationality of a given choice for him according to those other values.
Yes (or at least it would be up there on the list). It just isn't true in this case.
