Acclaim for the original edition of Nudge
Nudge has changed the world. You may not realize it, but as a result of its findings youre likely to live longer, retire richer, and maybe even save other peoples lives.
The Times (London)
Probably the most influential popular science book ever written.
BBC Radio 4
This gem of a book... is a must read.
Daniel Kahneman, Nobel Prizewinning author of Thinking, Fast and Slow
Engaging and insightful... The conceptual argument is powerful, and most of the authors suggestions are common sense at its best.... For that we should all applaud loudly.
The New York Times Book Review
This book is terrific. It will change the way you think, not only about the world around you and some of its bigger problems, but also about yourself.
Michael Lewis, author of Moneyball and Liars Poker
One of the few books... that fundamentally changed the way I think about the world.
Steven D. Levitt, coauthor of Freakonomics
Utterly brilliant... Nudge wont nudge youit will knock you off your feet.
Daniel Gilbert, author of Stumbling on Happiness
Nudge is as important a book as any Ive read in perhaps twenty years. It is a book that people interested in any aspect of public policy should read. It is a book that people interested in politics should read. It is a book that people interested in ideas about human freedom should read. It is a book that people interested in promoting human welfare should read. If youre not interested in any of these topics, you can read something else.
Barry Schwartz, The American Prospect
Engaging, informative, and thoroughly delightful.
Don Norman, author of The Design of Everyday Things and The Design of Future Things
A wonderful book: more fun than any important book has a right to beand yet it is truly both.
Roger Lowenstein, author of When Genius Failed
Save the planet, save yourself. Do-gooders, policymakers, this ones for you. Newsweek
Great fun to read... Sunstein and Thaler are very persuasive.
Slate
Nudge helps us understand our weaknesses, and suggests savvy ways to counter them. The New York Observer
Always stimulating... An entertaining book that also deeply informs. Barrons
Entertaining, engaging, and well written... Highly recommended.

This Poor Richards Almanack for the twenty-first century... shares both the sagacity and the witty and accessible style of its eighteenth-century predecessor. Law and Politics Book Review
There are superb insights in Nudge .

Preface to the Final Edition
The original version of Nudge was published in the spring of 2008. While we were writing it, Thaler got his first iPhone and Sunstein his first BlackBerry. In his first term as a United States senator, our former University of Chicago colleague Barack Obama had decided to challenge Hillary Clinton for the Democratic nomination for president. Senator Joe Biden was also doing that, without a whole lot of success. Real estate developer and reality television star Donald Trump was proclaiming that Clinton was fantastic and would make a great president. A financial crisis was emerging. Taylor Swift was nineteen years old (and had not yet won a Grammy), and Greta Thunberg was just five.
To say the least, a few things have happened in the intervening years. But Nudge continues to attract interest, and we have not been much inclined to tinker with it. Why a revision now? As we discuss in the book, status quo bias is a strong force.
Very much in keeping with the books spirit, we were induced to emerge from our slumber by a seemingly small matter. The contracts for the American and British paperback editions had expired, and new ones had to be agreed upon. Editors asked whether we might want to add a new chapter or possibly make other changes. Our immediate reaction was to say no. After all, Thaler is famously lazy and Sunstein could have written an entirely new book in the time it would take to get the slow-fingered Thaler to agree to anything. Besides, we were proud of the book, and why mess with a good thing?
