Behavioral bias.

Summary Economists and behavioral psychologists have identified a series of cognitive biases that alone would explain why our decisions, which should always be in our best interests, are often irrational. They propose that public action relies on these same biases in order to orient our choices, by considering us as organ donors by default, by bringing vegetables closer together and keeping French fries apart at the canteen, by sticking flies to the bottom of urinals, by making speed detectors smile or grimace, or by telling us that we recycle less than our neighbors. Thanks to these "nudges", which are so easy to implement and so inexpensive, we are encouraged to adopt a behavior that helps solve many problems, whether ecological, sanitary, financial or fiscal, without thinking about it or even understanding the issues at stake. Isn't the main bias to reduce political and social issues to problems of individual behavior? This book offers a critical analysis of this knowledge and its application, and explains its success and limitations.
