¡°A cultural phenomenon [that] finally brought behavioral economics into the mainstream . . . This version of the book is chock-full of new ideas. . . . Since the pandemic began, governments and companies around the world have had to think creatively about how to nudge people to wear masks, socially distance, and get vaccinated. And we¡¯ve seen a lot of creative campaigns that adopt strategies outlined in Nudge.¡± ¡ªNPR¡¯s Planet Money
¡°Few books can be said to have changed the world, but Nudge did. The Final Edition is marvelous: funny, useful, and wise.¡± ¡ªDaniel Kahneman, #1 New York Times bestselling author of Thinking, Fast and Slow
¡°Nudge should be required reading for anyone who aspires to run a country, lead a company, raise a child, or make a choice.

¡°Revolutionary. Once you¡¯ve read it, you start seeing the evidence everywhere. Evidence that economic orthodoxy is woefully out of date, that as humans we¡¯re not always rational, and that in every bit of architecture, design, and economic choice, we are ALWAYS being nudged in some way. Once we see and accept that, we can ask how we can make better choices. This book points us in the direction. It changes the way you see the world¡ªthis edition even more so.¡± ¡ªDavid Byrne, musician
¡°In the spirit of Donald Norman¡¯s The Design of Everyday Things . . . Thaler and Sunstein deliver a spirited argument to enable well-informed people to overcome various biases and ¡®probabilistic harms¡¯ to do what is best for them and, in the present case, their fellow ¡®American Humans.¡¯ . . . Students of design, politics, economics, and many other fields will delight in these provocative discussions.¡± ¡ªKirkus Reviews

Common "Nudges"
1. The design of menus gets you to eat (and spend) more. For example, lining up all prices on either side of the menu leads many consumers to simply pick the cheapest item. On the other hand, discretely listing prices at the end of food descriptions lets people read about the appetizing options first¡¦; and then see prices.
2. "Flies" in urinals improve, well, aim. When Amsterdam's Schiphol Airport was faced with the not uncommon issue of dirty urinals, they chose a unique solution: by painting "flies" in the (center of) commodes, men obligingly aimed at the insects, reducing spillage by 80 percent.
3. Credit card minimum payments affect repayment schedules. Among those who only partially pay off credit card balances each month, the repayment level is correlated with the card's minimum payment ¡ª in other words, the lower the minimum payment, the longer it takes a consumer to pay off the card balance.
4. Automatic savings programs increase savings rate. All over the country, companies are adopting the Save More Tomorrow program: firms offer employees who are not saving very much the option of joining a program in which their saving rates are automatically increased whenever they get a raise. This plan has more than tripled saving rates in some firms, and is now offered by thousands of employers.
5. "Defaults" can improve rates of organ donation. In the United States, about one£¿third of citizens have signed organ donor cards. Compare this to Austria, where 99 percent of people are potential organ donors. One obvious difference? Americans must explicitly consent to become organ donors (by signing forms, for example) while Austrians must opt out if they do not want to be organ donors.
