Dubner, Stephen J. and Steven D.Levitt - Freakonomics

Assume nothing, question everything. This is the message at the heart of Freakonomics, Levitt and Dubner's rule-breaking, iconoclastic book about crack dealers, cheating teachers and bizarre baby names that turned everyone's view of the world upside-down and became an international multi-million-copy-selling phenomenon. Asking provocative and profound questions about human motivation, Freakonomics will make you see the familiar world through a completely original lens.
