"Freakonomics" is a book by Steven D. Levitt and Stephen J. Dubner that explores the hidden side of everyday life through the lens of economics. It examines how incentives shape human behavior and uses data analysis to uncover surprising truths about various social issues, such as crime rates and education. The authors employ a range of real-world examples to illustrate their points, challenging conventional wisdom. By applying economic theory to diverse topics, including parenting and cheating, "Freakonomics" encourages readers to think critically about the world around them and the underlying factors that drive decisions.
