In Nudge, Thaler and Sunstein invite us to enter an alternative world, one that takes our humanness as a given. They show that by knowing how people think, we can design choice environments that make it easier for people to choose what is best for themselves, their families, and their society. Using colorful examples from the most important aspects of life, Thaler and Sunstein demonstrate how thoughtful “choice architecture” can be established to nudge us in beneficial directions without restricting freedom of choice. Nudge offers a unique new take—from neither the left nor the right—on many hot-button issues, for individuals and governments alike. This is one of the most engaging and provocative books to come along in many years.
