A sportsman catches a ball without calculating its speed or distance. A group of amateurs beats the experts at playing the stock market. A man falls for the right woman even though she's 'wrong' on paper. All these people succeeded by trusting their instincts - but how does it work? In Gut Feelings psychologist and behavioural expert Gerd Gigerenzer reveals the secrets of fast and effective decision making. He explains that, in an uncertain world, sometimes we have to ignore information and rely on our brain's 'short cut', or heuristic. By explaining how intuition works and analysing the techniques that people use to make good decisions - whether it's in personnel selection or heart surgery - Gigerenzer will show you why gut thinking can change your world.
