Thaler says this book is for lay readers. Don't let him fool you. With no previous exposure to economics literature, you'll be fairly lost most of the time. (Hell, I'm an economics doctoral student and I spent most of chapters 4 and 9 telling myself, "Just keep reading. It'll make sense eventually.") If this book weren't required reading for one of my classes, I probably wouldn't have started it, and definitely wouldn't have finished it.
