Nudge (book)

*Nudge* is a book by Richard Thaler and Cass Sunstein that explores how small design changes, called "nudges," can influence people’s decisions while preserving their freedom of choice. These gentle prompts aim to improve choices in areas like health, finance, and environment—such as default options for retirement savings or better cafeteria layouts. The authors argue that well-crafted nudges can lead to better individual and societal outcomes without restricting options, fostering smarter decision-making through understanding behavioral tendencies and designing environments that subtly guide people toward beneficial behaviors.
