Every day we make decisions on topics ranging from the personal investments we select to the schools we pick for our children to the foods we eat to the causes we champion Unfortunately, as authors observe, we don't always choose well The reason is that we all are susceptible to cognitive biases and blunders that make us human, fallible, and prone to error Thaler and Sunstein invite us to enter an alternative world, one that recognizes our humanness as a given They show that the way we think can be used to our advantage it is possible to design environments that make it more likely for us to act in our own interests
