Scientific and philosophical concepts can change the way we solve problems by helping us to think more effectively about our behavior and our world. Surprisingly, despite their utility, many of these tools remain unknown to most of us. In Mindware, psychologist Richart E. Nisbett presents these ideas in clear and accessible detail. Nisbett has made a career of studying and teaching such powerful problem-solving concepts as the law of large numbers, statistical regression, cost-benefit analysis, sunk costs and opportunity costs, and causation and correlation, probing the best methods for teaching others how to use them effectively in their daily lives. In this book, Nisbett shows how to frame common problems in such a way that these scientific and staitistical principles can be applied to them. The result is a practical guide to the most essential tools of reasoning ever developed--tools that can easily be used to make better professional, business, and personal decisions.--From publisher description.
