Freakonomics. Its not about economics in the dry, dismal sense that I remember from college. This is more about counterintuitive turns of logic, data showing causations that no one really supposed made sense. In the end, its about economics in the sense that real estate agents, sumo wrestlers and criminals respond to financial, social and lifestyle incentives.
Oh, and the book features twenty misspellings of the name “Jasmine”, a bit on two brothers named Winner and Loser, and a person named Shithead. Predictably, the last was my favorite.
