Desc: A Theory: Directed by Ólafur Jóhannesson. With Guy Kent. Some grapple with the challenge of treating other human beings decently. Others are just-a**holes, claims Professor Aaron James in his New York Times bestselling book, A**holes: A Theory. This intellectually provocative film takes a playful approach to uncovering why a**hole behaviour is on the rise in the workplace, in government, and at home.
