Psychopaths seem to be over represented in management

Paul Barry writes in Are business leaders psychopaths? that yes they are. To quote from his article:

According to the study's co-authors, Belina Board and Katarina Fritzon from the University of Surrey, this means that they are likely to display, "Superficial charm, insincerity, egocentricity, manipulativeness, grandiosity, lack of empathy, exploitativeness, independence, perfectionism, excessive devotion to work, rigidity, stubbornness, and dictatorial tendencies."
