No, really, this is important; don’t laugh, you’ve gotta read this article. This excerpt shows why:
“What separates the asshole from the psychopath is that he engages in moral reasoning (he understands that people have rights; his entitlement simply leads him to believe his rights should take precedence). That this reasoning is systematically, and not just occasionally, flawed is what separates him from merely being an ass. (Linguistics backs up the distinction: ass comes from the Latin assinus, for ‘donkey,’ while the hole is in the arras, the Hittite word for ‘buttocks.’)”
In other words, if your boss isn’t merely an asshat, but is a full-blown asshole, the odds are pretty strong that you’re working for a psychopath.
