The completely updated, final edition of the global bestseller - one of the most influential books of the 21st century 'Few books can be said to have changed the world, but Nudge did. The Final Edition is marvellous: funny, useful, and wise' Daniel Kahneman Nudge has transformed the way individuals, companies and governments look at the world - and in the process has become one of the most important books of the twenty-first century. This completely updated edition offers a wealth of new insights for fans and newcomers alike - about COVID-19, diet, personal finance, retirement savings, medical care, organ donation, and climate change. Every day we make decisions: about the things we buy or the meals we eat; about the investments we make and the time we spend; about our health and that of the planet. Unfortunately, we often choose badly. We are all susceptible to biases that can lead us to make bad decisions that make us poorer, less healthy and less happy. And, as Richard Thaler and Cass Sunstein show, no choice is ever presented to us in a neutral way. But by knowing how people think, we can make it easier for them to choose what is best for themselves, for their families and for society. With brilliant insight and wonderful levity, Thaler and Sunstein demonstrate how best to nudge us in the right directions, without ever restricting our freedom of choice.
