Freakonomics
A witty book that makes lots of clever observations about social issues by applying the rigor of economics and an open mind to a variety of intriguing questions. If drugs are such a terrific business, why are so many drug pushers impoverished? How might Roe v. Wade have affected crime rates? What can we learn by studying the names people choose for their babies? The common thread here is to gather observational data in statistically useful samples and then to study that data creatively and dispassionately.
