Abstract
This seminal work introduces the concept of Choice Architecture—the design of environments in which people make decisions. The authors argue that by understanding cognitive biases, choice architects can design 'nudges' that move people toward decisions that improve their lives, without limiting their freedom of choice (libertarian paternalism).
Methodology
Synthesizing decades of behavioral science research and applying it to real-world policy problems, including retirement savings, organ donation, school choice, and environmental protection.
Findings
Demonstrates that active defaults, social comparison, and structured choice architecture can significantly increase positive social outcomes. For instance, automatic enrollment (Save More Tomorrow) dramatically boosts employee savings rates.
Applied nudge
Use default enrollment for critical services (pensions, subscriptions, health checks) while maintaining a clean, single-click opt-out.
