I remember reading somewhere that people think there’s an equilibrium. If a few people are psychopaths, then they successfully defect against a gullible society that never expected them. If lots of people are psychopaths, then everyone just screens for psychopaths really hard, or the psychopaths start trying to psychopath each other.
I remember the way it was phrased was really convincing, but it doesn’t sound that convincing when I talk about it, especially if I’m not allowed to bring in group selection.
On the other hand, something like this *has* to be true, since we’ve been social animals for tens of thousands of years but psychopath genes haven’t come to dominate everything.
