I loved this outline of the book Predictably Irrational, and I also love the idea of a Book Outlines Wiki.
I'm convinced that human society has let technology and science get way ahead of our understanding of human behavior. Far more engineering projects fail because of human foibles than because we don't have sufficient technical skills or resources to solve the problem at hand. Likewise, I bet more money is wasted due to ignorance of our own nature than due to technical inefficiencies in the market itself. So I'm always glad to learn more about my own biases and psychological inefficiencies.
