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.
Nope, not for everyday decisions. For me "remember to update" is more of a mantra to remember to change your mind at all - especially based on several pieces of weak evidence, which normal procedure would be to individually disregard and thus never change your mind.
