Think less – and know more. A sportsman can catch a ball without calculating its speed or distance. A group of amateurs beat 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 too much information and rely on our brain’s ‘short cut’, or heuristic. By explaining how intuition works and analyzing 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.
