What's exactly is Pre-Slection? There has been many conflicting ideas and I don't know which one it is, some say it's due to the girl being lazy and using others to judge your alphaness and some say it's due to the confidence you show when you're with a girl.

But what exactly is the chemistry behind this? More specifically, why would a woman go after a man who she would have competition? Is it because women (and men) want things we can't have?

Also, how can you use pre-selection to your advantage in high school?
