SuperFreakonomics by Steven D. Levitt and Stephen J. Dubner

SuperFreakonomics, the sequel to the bestselling Freakonomics, comes out today. Like the original, it is a provocative collection of surprising stories and observations: Prostitution has declined over the years not because society has become more moral, but because more women have sex for free; you may not be able to recognize a terrorist by simply looking at a person, but a fairly reliable terrorist profile exists; a drunk walker is eight times more likely to get killed than a drunk driver. Unifying this seemingly random collection of observations are the themes that incentives matter and unintended consequences are commonplace. While the evidence supporting some of the claims seems dubious, if you enjoyed Freakonomics, you will probably enjoy SuperFreakonomics as well.
