I flat-out love this book. The authors' easy, accessible style makes it a joy to understand some hard realities: we all make irrational decisions because we're loss-averse, we have trouble letting go of the past, we attribute value to the wrong things, we suffer from diagnosis bias or fairness bias (among others). The examples are real-world and illuminating. The self-awareness I gained by reading the book is stunning.

I re-read the Epilogue every few months. It gently reminds me what to watch for in my thinking and reinforces why that vigilance is important. The authors write, "...it's easy to forget that under the surface we humans are still influenced by irrational psychological forces that can undermine a logical perspective on the world around us. The fact is, all of us are swayed at times by factors that have nothing to do with logic or reason."

A really smart rational decision? Read this book.
