Sure, but rationalists should win.
I'm not sure that being a rationalist gives you a significant advantage in interpersonal relationships. A lot of our brain seems to be specifically designed for social interactions; trying to use the rational part of your brain to do social interactions is like using a CPU chip to do graphics instead of a GPU; you can do it, but it'll be slower and less efficient and effective then using the hardware that's designed for that.
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.
