Professor Kahneman, a psychologist and winner of the 2002 Nobel Prize in Economics, "for having integrated insights from psychological research into economic science, especially concerning human judgment and decision-making under uncertainty", does just that. He shows us how we make decisions and how we, very often, are not aware how we make them even though we think we are fully logical and in control. This book provides ample moments for self-reflection and also practical tips for preventing bias in decision making.

At times the book is not easy to read. At times the tone seems a bit childish where at other moments the tone is more academic. I really liked the short summaries at the end of each chapter.

For (project) managers and executives there is enough material here to seriously start rethinking and evaluating the way we make decisions and come to conclusions. For that reason alone I can highly rcommend the book. Kahneman's work has been very influential in recent years in the realm of forecasting and project governance.
