What it's about
Thaler tells the story of how he spent four decades gathering evidence that real people systematically deviate from the rational, self-interested actor economics assumes, and how he fought a skeptical profession to get those deviations taken seriously. The book argues that economics improves when it drops the fiction of Homo economicus and studies Homo sapiens instead, and it matters because that argument eventually reshaped policy, finance, and how economists build models.

Who it's for
- Anyone who has wondered why they overpay for things they don't need and underinsure the things that matter - Students or professionals in economics, policy, or finance who want the founding arguments of behavioral economics from the source - Readers curious about how a heterodox idea fought its way into the academic mainstream
What’s inside
- 1The List on the Office Door1 min
Everyday anomalies that violate standard economic predictions are not noise to be dismissed but data pointing to systematic, predictable patterns in human choice.
- 2Endowment and the Mug Experiment1 min
People value what they already own more than they value the identical thing they don't yet own, a gap that markets and models routinely ignore.
- 3Mental Accounting1 min
People don't treat money as fully fungible; instead they sort it into separate mental budgets that shape spending and saving in ways formal wealth accounting cannot explain.
- 4Self-Control and the Two Selves1 min
Human beings are better modeled as containing two competing internal agents, a impulsive doer and a long-term planner, than as a single unified rational chooser.
- 5Fairness and the Ultimatum Experiments1 min
Perceived fairness constrains what firms and markets can actually do, even when unfair pricing would be profit-maximizing under standard theory.
- 6The Battle Over Efficient Markets1 min
Financial markets, long assumed to price assets correctly because rational arbitrageurs correct any mistakes, in fact show persistent anomalies that arbitrage does not eliminate.
- 7Save More Tomorrow1 min
Because willpower fails at the moment of choice, the most effective way to fix undersaving is to redesign the default and timing of the decision rather than to appeal to reason.
- 8Nudges and Choice Architecture1 min
Because no policy or product design is neutral, and defaults and framing always influence choice, designers have a responsibility to set defaults that help people rather than exploit them.
- 9From Heresy to Institutional Change1 min
Behavioral economics succeeded not primarily because its academic arguments were airtight but because persistent evidence accumulation eventually forced a resistant discipline to change its models.
