This doesn't require becoming a behavioral scientist. If you act like an escapee from the penal system for the criminally insane, most women will avoid you (people in general for that matter). If you seem like you've been living in mom's basement for the past 10 years, most people will think you a bit strange. If you act like you're gay, well, most people will assume you might be gay.
So I can tell you've already realized it's a continium.

I don't imagine you want to be at either extreme. It's not easy to consistently hit the sweet spot, but when you do you'l know it because you'll feel talkative, alive, and want to interact with people. When you've hit that spot, at least in my experience, interactions take care of themselves... no weirdo, PUA, pretending to be someone else stuff required. A big part of this is realizing your own & others' intrinsic values and to stop obsessing with external indicators of "success" or "failure" as defined by corporate culture. By those external standards one is never good enough and it leads to a striving for superiority where one never feels quite good enough but always believes that just one more lay, degree, promotion, etc will provide that sense of inner security.
