What it's about
Steven Levitt and Stephen Dubner argue that economics is less about money than about incentives, and that hidden incentives explain behavior that seems mysterious or moral on its surface. Using data instead of ideology, they reexamine crime, cheating, parenting, and crack dealing to show that conventional explanations often mask simpler, less flattering causes. The book mattered because it made applied statistical reasoning popular reading and pushed economists toward messy real-world questions outside markets.
