Nudging

Richard Thaler and Cass Sunstein's concept of designing CHOICE ARCHITECTURE to gently steer behavior toward better outcomes without restricting freedom of choice—making the desired option the easiest, most natural choice without forbidding alternatives. The mechanism: people follow the path of least resistance, so redesigning the path changes behavior more effectively than education or persuasion. Making organ donation opt-out instead of opt-in dramatically increases donation rates. Placing healthy food at eye level increases consumption. Default enrollment in 401(k) plans dramatically increases retirement savings. As a mental model: nudging exploits the gap between what people INTEND to do and what they ACTUALLY do by making the intended behavior easier.

When to use it

When behavior change needs to work with rather than against human defaults; when choice architecture would be more effective than education or persuasion; when defaults and friction are the primary determinants of behavior; when ethical behavioral design would improve outcomes without restricting choice.

How it can help

Design choice architecture that makes desired behaviors the path of least resistance. The nudging toolkit: (1) DEFAULTS: make the desired option the default (opt-out rather than opt-in). (2) SALIENCE: make the desired option the most visible and accessible. (3) SOCIAL PROOF: show that the desired behavior is what most people do. (4) SIMPLIFICATION: reduce friction for the desired behavior and add friction for undesired behavior. (5) TIMING: present choices when people are most likely to choose well. For organizations: most behavioral change fails because it requires effort; nudging succeeds because it REMOVES effort.
