There is a special kind of intelligence for dealing with risk and uncertainty. It doesn't correlate with IQ, and most psychologists failed to spot it because it is found in such a disparate, rag-tag group of people - American weather-forecasters, professional gamblers, and hedge-fund managers, for example.This book shows just how important risk intelligence is. Many people in positions which require high risk intelligence - doctors, financial regulators and bankers, for instance - seem unable to navigate what Evans calls the "darkened room", the domain of doubt and uncertainty. Risk Intelligence is a traveller's guide to the twilight zone of probabilities and speculation. Evans shows us how risk intelligence is vital to making good decisions, from dealing with climate change to combating terrorism.
