With facts in hand, humans can use reasoning to arrive at new knowledge and make good decisions. Yet, in everyday life, we show poor logical skills, we overlook or willfully ignore established facts, we yield to biases and gut feelings. This may be explained by a model of human thinking in which two systems coexist: One system delivers intu­itions, fast, while a second system is slow and more unwieldy but can be trusted for deliberate, conscious, calculated thought. In The Influential Mind, neuroscientist Tali Sharot explores the tension in this relationship, creating a picture in which modern logic is compromised by a much older, biased, heuristic system.
