Best quotes
Here are some notable quotes from Freakonomics:
- “Morality, it could be argued, represents the way that people would like the world to work – whereas economics represents how it actually does work.”
- “The conventional wisdom is often wrong.”
- “Knowing what to measure and how to measure it makes a complicated world much less so.”
- “If morality represents the way things should work, then economics represents how they do work in the absence of morality.”
- “Economics is a study of incentives, how people get what they want or need, especially when other people want or need the same thing.”
- “People respond to incentives, although not necessarily in ways that are predictable or manifest. Therefore, one of the most powerful laws in the universe is the law of unintended consequences.”
- “The three hardest tasks in the world are neither physical feats nor intellectual achievements, but moral acts: to return love for hate, to include the excluded, and to say, ‘I was wrong.’”
- “Conventional wisdom is often wrong. And conventional wisdom about money is almost always wrong.”
- “One of the lessons of economics is that the world is complicated. A corollary of this lesson is that people often behave in quite different ways than they should, or than we might predict, or than they themselves might predict, given the incentives they face and the information they possess.”
- “The numbers have no way of speaking for themselves. We speak for them. We imbue them with meaning.”

The book is divided into six parts, with each part containing several chapters that delve into specific topics. The first part of the book is titled “What Do Schoolteachers and Sumo Wrestlers Have in Common?” and examines the incentives that drive human behavior. The authors use data analysis to uncover the incentives that drive teachers to cheat on standardized tests and sumo wrestlers to throw matches.
The second part of the book, “How Is the Ku Klux Klan Like a Group of Real-Estate Agents?”, explores the concept of information asymmetry and the role it plays in various markets.

The fourth part of the book, “Where Have All the Criminals Gone?”, explores the correlation between the drop in crime rates in the United States in the 1990s and the legalization of abortion two decades earlier.
