What is behavioral design?

Behavioral design is a field that combines principles from psychology, behavioral economics, and design to create products, services, or environments that positively influence people's decisions and actions. Practitioners study how people actually behave and then use that understanding to design interventions, such as nudges or choice architecture, which help users make better decisions. Behavioral design is commonly applied in areas like health, finance, and technology to encourage desirable behaviors without restricting freedom of choice.
