I come from a rather unstable and violent corner of the world, and I've met plenty of psychopaths growing up. I have a hypothesis that early childhood traumas and violent environment can trigger the development of psychopathic tendencies, but I'm not entirely sure how much role does genetics play in this process.
Some of the commenters on this topic seem to ascribe superhuman rationality and brainpower to psychopaths. I don't think that's a correct way to look at it. They can be very smart, but they suffer from the same set of biases and blind spots and Dunning-Kruger type of phenomena as other people. I think the defining characteristic is the complete lack of empathy and the willingness and ability to manipulate people (practicing the skill from early childhood, hence very good at it).
I was just looking up one of the smartest and most pronounced psychopaths I've met in recent years. Apparently he got his MBA and started an offshore private equity fund, seems to be doing well for himself. The guy had monumental talent for manipulating people. I wonder how far will he go before people catch on to his true nature...
