Nudging is a concept in behavioral economics that involves subtly guiding individuals toward making better choices without restricting their options. It leverages insights from psychology to influence decisions in a positive way, often by changing the way choices are presented. For example, placing healthier food options at eye level in a cafeteria can encourage better eating habits. The term was popularized by the book Nudge by Richard Thaler and Cass Sunstein, which discusses how small changes in the environment can lead to significant improvements in decision-making. Nudging is used in various fields, including public policy, health, and finance, to promote beneficial behaviors.
