Overview

Nudge explores how subtle changes in the way choices are presented can significantly influence people's behavior without restricting their freedom. This concept, known as 'choice architecture,' helps individuals make better decisions in areas such as health, finance, and public policy.

The authors argue that humans often make irrational decisions due to biases and heuristics. By designing environments that 'nudge' people toward beneficial choices, society can improve outcomes while preserving autonomy. The book combines behavioral economics insights with practical applications.

Through numerous examples and case studies, Thaler and Sunstein demonstrate how nudges can be implemented in real-world settings. They emphasize the ethical considerations and advocate for 'libertarian paternalism,' a philosophy that respects freedom while guiding choices for better welfare.
