So I picked this up on a strangers claim that it was great. Why do I do this? Anyway, it's great for a sceptic book. But it still has all the stuff I already know from somewhere else, some guilt inducing questions of how do we know the things we know that I don't know the answers to, and I guess one fact I didn't know because it wasn't too interesting which was partially the point It's fun to report mystery crop circles, much less fun to report on how pranksters made those crop circles for 16 years. I didn't know it was pranksters, and if I had heard, I had forgot about it.. Despite all that, it was a pleasant listen (except for the depressing parts on the witch-hunts), and if there's someone doubting science in your life this might be a book to suggest to them.
