The Psychopath Test. The most intriguing part is a true story of a man who fakes insanity to get off on an assault charge, but spends many years (even after he would have been out of prison), locked up in a mental health facility.
He keeps trying to tell them that he’s not insane, but no one believes him. He acts passive and calm, and they say that he can’t be sane because he is thriving in the mental hospital and a normal man would be angry.
So he acts angry and tries to prove he doesn’t belong there, and they say his psychosis is progressing.
….How do you prove you’re sane?
