Behavioural economics is an odd term. As Warren Buffettโs business partner Charlie Munger once said, โIf economics isnโt behavioural, I donโt know what the hell is.โ Itโs true: in a more sensible world, economics would be a sub-discipline of psychology. Adam Smith was as much a behavioural economist as an economist โ The Wealth of Nations (1776) doesnโt contain a single equation. But, strange though it may seem, the study of economics has long been detached from how people behave in the real world, preferring to concern itself with a parallel universe in which people behave as economists think they should.
