If I'm not mistaken, a high percentage of psycopaths have high IQs. It's one of the classic profile traits used to represent the stereotipical psycho.

edit: I searched a little bit on this and it seems that it was just a myth propagated by movies and a few very famous cases, i.e. Ted Bundy. But anyway, I do not see how you can make an argument from I wrote on the original post implying a correlation between psycopathy and high IQ. Is it the avoiding of having children, since it's an effective burden on the prospective father? It's just a fact, sexual drive was enough to make a man reproduce in the past. Not anymore. Natural selection wins again, the rules of the game changed, so you're out.
