Public-health campaigns sometimes assume that giving people more information about a risk will change their behavior. A 2023 review of forty studies on smoking, diet, and physical activity challenges this assumption: across decades and contexts, information-only interventions produced small, often short-lived effects. The studies that succeeded combined information with structural changes — taxes, defaults, redesigned environments. Information, the review argues, is necessary but rarely sufficient.
