Jon Ronson seems to be unclear what he wants to achieve in this book, resulting in a meandering narrative which easily gets distracted. The writer is very honest in his approach to identifying psychopaths and acknowledges that he is an amateur in a confusing world. In this respect I found him refreshing and admired how he was able to look at a complicated subject then discuss it in such an engaging manner. Particularly revealing is a reported conversation with a friend who accuses JR of only reporting the bits of info that support his thesis (don't most of us do this?) I didn't find it a funny book as many seem to have done but did appreciate the light hearted way he talks about his investigations. My main difficulty is with the time frames. JR meets lots of people who have stories to tell which, inevitably, have happened at different times. This bouncing back and forwards, along with JRs habit of including his past experiences makes the time setting a major distraction. All of that aside I was transfixed by the concepts in this book and it will stay in my head for some time. Could have done with a bit more structure but, other than that, great. I have also decided that there is some part of me which is a psychopath!!!
