A person can be poorly psychologically calibrated for their environment without being defective and in need of change.
Yes, they do need to change... their environment. :-)
(Generally, this can be much more easily and effectively achieved by starting to hang around different people than by trying to modify the ones they're already hanging around with.)
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.
