Nudging

Nudge or Nudging refers to any aspect of the decision environment, also called choice architecture, "that alters people's behaviour in a predictable way without forbidding any options or significantly changing their economic incentives" (Thaler and Sunstein, 2008, p. 8).

Typical nudging tools are:

• simplification and framing of information
• changes to the physical environment
• changes of the default policy
• use of social norms
