Mr. Kahneman, a Nobel Prize winner, explores the general subject of how and why we frequently make irrational decisions. We've all seen articles over the years on various aspects of this phenomenon, but I venture to say that never before have the various aspects and permutations been explored in this depth and specificity. Mr. Kahneman has spent much of his life researching the subject, and since the book includes both his research and that of others, it must stand as the definitive compendium on the subject. His credentials are indisputable, and he tries gamely to bring the subject to life, but -- mea culpa -- I just couldn't stay interested in the myriad of data and specific examples. The book is good for someone really interested in the details, and it does contain real life examples, but after 400 pages it's hard to remember them. My takeaway: Our intuition is frequently wrong, and even our experience (or what we believe our experience to have been) may not be reliable as a decision guide. So, be careful!
