'The witty aphorism, 'never attribute to malice that which can be adequately explained by stupidity', suggests that malice and stupidity are distinct, that ethics and knowledge are two separate aspects of decision making. But what if they are closely connected? The author of this original and insightful book, Boudewijn de Bruin, brings together classical ethical theory, recent psychological research, and a deep understanding of modern financial practice to offer a prescription for reforming our troubled financial system that focuses on the character of decision makers. The provocative idea that the act of knowing has a moral dimension and carries with it moral responsibility provides a novel and fruitful approach to much-needed financial reform.'
