"Anyway, when I asked Dr. Stout if there’s any truth to the contention that politicians are more likely to be psychopaths, she said in an email that no solid statistics were available to prove or disprove the hypothesis. Yet despite the lack of proof, she gave a surprisingly definitive answer to my question:
Yes, politicians are more likely than people in the general population to be sociopaths. I think you would find no expert in the field of sociopathy/psychopathy/antisocial personality disorder who would dispute this... That a small minority of human beings literally have no conscience was and is a bitter pill for our society to swallow — but it does explain a great many things, shamelessly deceitful political behavior being one."
