Making a decision of any importance, is never simple. On the one hand, specialists in decision theory do not come within the reach of most policy makers and, secondly, there are very few books on pragmatic decision-making that are not purely anecdotal. In addition, there is virtually no book that links decision-making and action. This book provides a bridge between the latest results of decision-making, artificial intelligence, neurobiology, decision and action psychology. What role for intuition or emotion? What are the main psychological biases that we must be wary of? How to avoid being manipulated? What is the proper use of planning? How do we remain rational even if one is not an expert of probabilities? Perhaps more importantly for managers, how does one go from decision to action? So many questions fundamental to the practice of decision-making are addressed in this book. This book dissects all issues that arise almost daily to decision-makers, at least for major decisions. Drawing on many examples, this title answers, in plain language and imagery, all your questions. The final chapter takes the form of a brief summary, all you must remember is to be a good decision-maker.
