1. When women say they like smart guys they mean streets smart not social sciences smart, they they like socially adaptable conformists with a slight edge. The type of guy women get turned off is the self-reflective nerd who sees irony in the absurd things that constitute our everyday social reality.
  2. Women (outside fringe tumblr circles) really dislike that self-reflective humor nerdy guys have, unless you're a famous jewish comedian that type of self-analytic humor comes off as neurotic and women think you aren't "confident".
  3. Stuff like "having game", "confidence" or "rizz" requires being dumb to an extent in order to internalize extremely gendered behavior patterns uncritically, a intelligent guy will either have to be a psycho to mimic these, or he will see the irony in them and cringe at it.

I hate to sound like a nice guy here, but there are actual studies that show a correlation between iq and virginity, and a likely hood of more intelligent men to be single for longer periods of time. And its not because they're too smart for women. I believe women (on average that is) are turned off by smart, intellectual, nerdy men.
