Is it possible to train yourself the big five in personality traits? Specifically, conscientiousness seems to be correlated with a lot of positive outcomes, so a way of actively promoting it would seem a very useful trick to learn.
Not that I know of. The only current candidate is to take psilocybin to increase Openness, but the effect is relatively small, it hasn't been generalized outside the population of "people who would sign up to take psychedelics", and hasn't been replicated at all AFAIK (and for obvious reasons, there may never be a replication). People speculate that dopaminergic drugs like the amphetamines may be equivalent to an increase in Conscientiousness, but who knows?
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
