An updated and refreshed edition of the groundbreaking book that shows how people can be nudged toward decisions that will improve their lives  “If you’ve read Nudge and think you fully grasp the concept and its uses, you are mistaken. The new edition significantly deepened my understanding of what nudges are and how they can be employed. It truly is a must-read.”―Robert Cialdini, New York Times bestselling author of Influence  “Few books can be said to have changed the world, but Nudge did. The Final Edition is marvelous: funny, useful, and wise.”―Daniel Kahneman, #1 New York Times bestselling author of Thinking, Fast and Slow   Since the original publication of Nudge more than a decade ago, the word “nudge” has entered the vocabulary of businesspeople, policymakers, engaged citizens, and consumers everywhere. The book has given rise to more than 200 “nudge units” in governments around the world and countless groups of behavioral scientists in every part of the economy. It has taught us how to use thoughtful “choice architecture”—a concept the authors invented—to help us make better decisions for ourselves, our families, and our society.   Now, the authors have rewritten the book from cover to cover, making use of their experiences in and out of government over the past dozen years as well as the explosion of new research in numerous academic disciplines. It offers a wealth of new insights, for both its avowed fans and newcomers to the field, about a wide variety of issues that we face in our daily lives—COVID-19, health, personal finance, retirement savings, credit card debt, home mortgages, medical care, organ donation, climate change, and “sludge” (paperwork and other nuisances that we don’t want and keep us from getting what we do want)—all while honoring one of the cardinal rules of nudging: make it fun!
