Every day we make decisions. 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 Thaler and Sunstein show, no choice is ever presented to us in a neutral way. By knowing how people think, we can make it easier for them to choose what is best for them, their families and society. Using dozens of examples the authors demonstrate how to nudge us in the right directions, without restricting our freedom of choice.
