This book came out ten years ago. It discusses how people make decisions. Not necessarily how people ought to make decisions--but how they do. It does have some advice on how people can make better decisions--not by trying to fight our natural decision-making patterns, but by nudging those patterns. It's well-written. I didn't get much out of it-- I'd already heard most of what it had to say. Risk of reading a classic. A fun read, but depending on what else you've read, maybe not the best use of your time.
