Richard H. Thaler’s Misbehaving: The Making of Behavioral Economics is part memoir, part intellectual history, and part takedown of the idea that people behave like perfectly rational “Econs.” Thaler argues that behavior isn’t noise, it’s data, and that understanding bias, self-control problems, and real-world incentives is essential for better strategy, finance, and leadership. From mental accounting to fairness to nudges and choice architecture, Misbehaving shows why markets are shaped by psychology as much as math. For MBA readers, it’s one of the most practical, memorable, and genuinely entertaining books in the modern business canon.
