Gut Feelings reveals the secrets of fast and effective decision-making. Gerd Gigerenzer analyses the heuristics that people actually use to make good decisions and shows us how we can become better decision-makers ourselves. In order to make a good decision in an uncertain world, one sometimes has to ignore information. The art is knowing what one doesn't have to know. Gigerenzer reveals the truth about everything from catching a ball to personnel selection and stock picking – even coronary unit decisons. This book will change the way people see the world and change the way they live in it.
