Sometimes we make good decisions. Other times, we make really bad ones. What is it that creates the difference? The answer tends to polarise. On the one hand, it is thought that the way to good decision-making lies in pure reason. The more logical and objective we are, the better the decision. On the other hand, people say that the best decisions are based on gut instinct. The most rigorous analysis is no substitute for a hunch. In this session, philosopher and psychologist Robert Rowland Smith will take us through the fascinating world of decision-making, and ask us to decide in turn whether making good decisions is a science or an art.
