A nudge is a behavioral intervention that alters human decision-making by changing the architecture of choice without forbidding options or materially altering economic incentives. Parameters: (1) it must preserve freedom of choice — removing an option makes it a prohibition, not a nudge; (2) it must not change financial incentives in a material way — that is information or regulation, not nudging; (3) it works by leveraging existing cognitive heuristics and biases, not by rational persuasion. The persistence mechanism is institutional design: once embedded in choice architecture by policy-makers, designers, or organizations, a nudge persists until actively removed or overwritten.

Definition
Why it is in scope
A nudge is a human-made behavioral intervention that alters decisions or actions without forbidding options or significantly changing incentives. It is a designed feature of choice architecture, not a natural phenomenon — the concept was formalized by Thaler and Sunstein as a tool for steering behavior within libertarian paternalism.

A nudge operates by exploiting existing cognitive shortcuts — without heuristics, nudges cease to function as the mechanism that defines them. Remove heuristics (make people perfectly rational) and a nudge is no longer a nudge but either information or a prohibition. This is constitutive, not merely facilitative.

A nudge IS a specific kind of intervention — a subtle change in the choice architecture that influences behavior without forbidding options. Specific→general per Law 9. A competent speaker would call a nudge 'an intervention.'
- cmreepxfw002yg8vuxaifbkjaSERVES →
Nudges are built for the sake of policy — behavioral interventions designed to influence outcomes without coercion. Law 8d: for whose sake? The nudge is the servant; policy is the master. Direction: servant→master.
