I think this is a great book with much insight about a large number of errors in our daily decision making. The book is easy to read, broken up in very short sections That can each be read in 30 mins or less, THUS making it a great commute book. It is not trivial HOWEVER take in. The truth about the field, and Kahneman himself Recognizes it, Is that it is silent in its infancy. Although very empirical (lots of experiments are Described Which make the argument much more convincing than other psychology books based only on small case studies and "expert opinions") it remains too descriptive for my taste THUS with all the author's efforts the book somewhat lacks structure , This is not his fault the consolidation required to reveal the structure, and Perhaps some predictive Consequences, Usually comes after much more generations of Researchers banging Their Heads for answers and much more empirical evidence.
Some reviewers mention That it is long winded but I think That depends on the reader. I think Kahneman did this partly Because repetition is useful to remember things When not enough structure is present and partly Because things are much more subtle than people are used to think. On this point I agree with the author did for this very social fenomena and, Because People Too Often think they already know what is being talked about, words can oft be false friends and developing a vocabulary is a tenuous albeit Absolutely Necessary Endeavor. (You'll understand When you read the book)
