[Freakonomics: A Rogue Economist Explains the Hidden Side to Everything] – by Stephen J. Dubner and Steven Levitt was a great book.
It was different. And I liked it.
Freakonomics makes you look at the world in a different way. The book explores the real reasons for the 1990s crime drop, information asymmetry, real estate agents, correlation vs. causation, and, most importantly, in the introduction, which discusses the fundamental principles of incentives. From then on, each chapter focuses on answering, or more so addressing an unusual question.
