Adam Smith, Behavioral Economist

Abstract

In The Wealth of Nations, published in 1776, Adam Smith famously argued that economic behavior was motivated by self-interest. But 17 years earlier in 1759, Smith had proposed a theory of human behavior that looks anything but self-interested. In his first book, The Theory of Moral Sentiments, Smith argued that behavior was determined by the struggle between what Smith termed the "passions" and the "impartial spectator." The passions included drives such as hunger and sex, emotions such as fear and anger, and motivational feeling states such as pain. Smith viewed behavior as under the direct control of the passions, but believed that people could override passion-driven behavior by viewing their own behavior from the perspective of an outsider—the impartial spectator—a "moral hector who, looking over the shoulder of the economic man, scrutinizes every move he makes" (Grampp, 1948, p. 317).
