Why did I love this book?
What I like about this book is that it deals with big ideas in very plain language, and is packed full of practical experiments and examples. This is all the more remarkable as the book actually started out as a 'post-hippy,' 1970s academic paper, entitled "Belief in the Law of Small Numbers," in which Daniel Kahneman and his lifelong collaborator, Amos Tversky, set out eleven "cognitive illusions" that affect human judgment. The book went on to define a whole new field, which can't be said for everyone! Its weakness is, I think, an insistence that being irrational is bad. Not always!
