Coincidence Squared?

For the past week I have (for the first time in my life) been researching psychopaths on the internet. I am doing this because of a piece of writing I want to do and have never done research of this type before. This morning I heard an article on Radio 4's Today programme about the analysis of coincidence and less than five minutes later there was a trailer for the programme "Saturday Live" on which Jon Ronson, the author of "The Psychopath Test" was to be interviewed. </p> <p>Coincidence squared?
