The old line that true wisdom comes when you realize how little you know is brought to mind by this book which shows us that we often respond to the world using a pre-wired quick-acting, but deeply flawed system of mental function. The author, a Nobel prize laureate, describes his theory of fast and slow methods of thought, which, at first, seems to be an analytical version of the id and ego dressed up and without attribution, but as the stories are told and the experimental results accumulate, we see an extraordinary far-reaching concept that has consequences for all human activity. Included are: explanations of how con men and salesman trick us so easily, the difficulty of comprehending simple statistical concepts, one of the best explanations of regression to the mean that I have ever read, more support for efficient market theory and debunking of those who predict the future, the reason why tourists need to take pictures and a discussion of the remembering self that gave me insight into Proust, tips on hiring, the basis of intuition and much more.
