Steering Human Behavior

Traditional economics assumes human beings are rational actors who always make decisions that maximize their own self-interest. However, behavioral economics has shown that people are often irrational and heavily influenced by the context in which choices are presented. This realization led to the development of 'Nudge Theory.' A nudge is a subtle change in the environment designed to alter people's behavior in a predictable way without forbidding any options or significantly changing economic incentives. ( 1 ), placing healthy food at eye level in a cafeteria is a nudge to encourage better eating habits, while still allowing people to choose junk food if they wish.

Critics argue that nudging can be manipulative, asserting that governments should not subtly steer citizens' choices, even for their own good. They believe this infringes on individual autonomy. ( 2 ), proponents argue that because the way choices are presented inevitably influences decisions anyway, it is better to design these presentations to improve health and wealth rather than leave them to chance. They term this approach 'libertarian paternalism.'

Nudges are now used globally in public policy. For instance, automatically enrolling employees in retirement savings plans has significantly increased savings rates. ( 3 ), sending text messages reminding people to pay fines has improved tax compliance. As understanding of human psychology grows, the use of nudges is likely to expand.
