For several years now, people have recommended I read Dietrich Dorner's The Logic of Failure. I finally did, and must say that it may be the most important book ever written for business executives. Dorner is a cognitive psychologist who studies decision making in complex situations. What he found is that human aren't very good at it. The book chronicles many of the common errors we make, and examines the ways we can improve our decision making skills. It isn't the most well written book I've ever read (probably because it was translated from German), but the ideas and principles espoused are extremely important, and are not found in many other texts. Instead of writing a lengthy review, I will instead direct you to David Foster's summary of the book. I highly recommend you read this if you want to become a better business executive.
