If your model were accurate it would imply high IQ and psychopathy would co-select wouldn't it? I know psychopaths tend to think they're smarter than anyone with ethics but doesn't the opposite correlation tend to hold?
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.
