Nudge: Improving Decisions about Health, Wealth, and Happiness by Richard H. Thaler, Cass R. Sunstein
2.0
This is a good complement to Cialdini's book on Influence, and was at times very interesting. Other times, however, it almost put me to sleep -- which is really bad because I listened to it while commuting.
