Overview

Nudge explores how subtle changes in the way choices are presented can significantly influence people's decisions without restricting their freedom. The authors introduce the concept of 'choice architecture' to help individuals make better decisions in various aspects of life.

The book combines insights from behavioral economics and psychology to demonstrate how nudges can improve outcomes in health, finance, and public policy. It argues for libertarian paternalism, where people are gently guided towards beneficial behaviors while preserving freedom of choice.

Through numerous real-world examples and experiments, Thaler and Sunstein show how small interventions can lead to better personal and societal results. The book encourages policymakers and organizations to design environments that promote smarter decision-making.
