Jon Ronson, a journalist, seeks out the more bizarre cases and treatments of psychopathy in The Psychopath Test. Along the way he introduces the reader to the Bob Hare Checklist which is widely used in the field to determine if a patient is a psychopath, the CCHR, a group founded by the Church of Scientology to investgate and expose psychiatric violations of human rights and a host of early experimental treatments for psychopaths that couldn't possibly be administered today. 
 It was an interesting read, but more entertaining than informative. The more I read, the more questions I had, specifically "How did they get away with that treatment?" or "What happened to that person after being released / confined?" There are a host of individuals and cases written about here that could send you down a wikihole of madness. But perhaps, I'll save that trip for another day. 
 3.5 stars and a good read.
