Nudging - Definition

“A nudge, as we will use the term, is 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.

Banning junk food does not.“ (Thaler & Sunstein, 2008)

But let’s face reality: so many companies would not invest so much money in advertising if they could not influence their customers…

P The initiatives around preventing and combating tobacco consumption worldwide are a great and successful example of reducing tobacco consumption in the public, combining information, empowerment, taxes, restrictions and nudging elements. Nudging can be seen as one important part of instruments in public health and healthcare, but is not able to replace education or laws.
