Since the original publication of "Nudge" more than a decade ago, the title has entered the vocabulary of businesspeople, policymakers, engaged citizens, and consumers everywhere. There are now over 400 nudge units worldwide utilizing the latest insights from behavioral science and thoughtful choice architecture to help us overcome the biases that lead to poor decisions and steer us toward the best choices for ourselves, our families, and our society.

This fully updated edition offers a wealth of new insights for both fans of the book and newcomers on topics such as COVID-19, nutrition, personal finance, retirement planning, credit card debt, mortgages, healthcare, organ donation, climate change, and sludge (the paperwork and other hassles we don’t want that prevent us from getting what we want) – all while keeping in mind one of the fundamental rules of nudging: Make it fun!.
