This book is a continuation of the fascinating study of strange acts committed by reasonable people (in economics and beyond), begun by the author in the book Predictably Irrational. Years of experimentation in the field of behavioral economics are reflected in a fascinating, serious and instructive story, this time about the unexpected benefits that our “weird” behavior can bring. And also about when and why high bonuses lead to worse results; how to guarantee that your work will be meaningless, even if you love it very much; why we get used to things, but not to everything and not always. A book for everyone who wants to learn more about the hidden forces that determine our behavior and make better decisions in the future.
