This book examines some of the common fallacies in thinking, and how we fool ourselves even when we think we're following the evidence. The author, who has taught critical thinking for years, examines pseudoscience, politics, and religion to discover ways in which we don't always think about things in a rational way. The very weakest part of the book was the conclusion, where the author just sort of seems to throw up his hands and say "oh, well, nothing to be done, and it doesn't really hurt anyone that much" - in spite of the fact that he has just worked his way through a myriad of ways in which it DOES hurt. Then he says he's going to give 59 ways to overcome your biases, but he really doesn't. He just lists 59 particular types of biases. Overall, a good book, but it could have been better. ( )
