The author offers us an excellent popular science book on recent discoveries in neuroscience of the decision. It shows how near a conscious reflection, rational and logical, most of our actions are guided by 'instinct' or intuitions which we often trust. It teaches us where that is a good thing and also shows us when it is better to be careful. The subject is undoubtedly fashionable, and several best sellers are now competing in this niche bookstore, including Malcolm Gladwell and Jonah Lehrer, or Antonio Damasio and Dan Ariely. If these topics interest you, this book by Gerd Gigenrenzer, renowned German psychologist, is undoubtedly one of those that must be read to enter the science of intuition and decision.
