Jon Ronson sets out on a journey to figure out how mental illness, most specifically psychopathy interacts with the modern world. What follows is an interesting journey through reality tv (where producers identify the right kind of madness), the insanity ward of a prison, and the mansion of a prominent CEO, all havens of alleged psychopaths. In the end, Ronson decides that diagnosis is not so easy, wondering whether someone should be judged by their sanity or their psychopathy.
