Nudging by Shaming, Shaming by Nudging

In both developing and developed countries, health ministries closely examine use of so-called nudges to promote population health and welfare. Cass Sunstein and Richard Thaler, who developed the concept, 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 nudge, the intervention must be easy and cheap to avoid. Nudges are not mandates” (1).
