Nudge: any aspect of the choice architecture that predictably alters people's behavior without forbidding any options or significantly changing their economic incentives, functioning as environmental adjustments that make one option more salient, more accessible, or more automatic than its alternatives
Why This Is a Definition

It distinguishes nudges from bans, commitment devices, and other interventions.
