According to an article by The Huffington Post, these are the occupations that people with psychopathic tendencies are drawn to.

I was very surprised.  I would have thought we were #1.  The article describes psychotics as "characterized by shallow emotions (in particular reduced fear), stress tolerance, lacking empathy, coldheartedness, lacking guilt, egocentricity, superficial char, manipulativeness, irresponsibility, impulsivity and antisocial behaviors such as parasitic lifestyle and criminality."
