The Importance of Choice Architecture in Politics

The book argues that policymakers should be designing environments to encourage the choice that people themselves would make. They define a nudge as any aspect of the choice architecture that alters people's behavior in a predictable way without forbidding any options or significantly changing their economic incentives. To count as a mere nudge, the intervention must be easy and cheap to avoid. Putting fruit at eye level counts as a nudge, banning junk food does not.
