Primes¶
- Activation Energy
- Economics & policy: Implementation barriers, regulatory hurdles, market-entry costs, supermajority requirements (legislative activation energy), infrastructure investment as energy to unlock economic zones; Thaler and Sunstein (2008) frame these as choice-architecture frictions whose reduction acts as policy-level activation-energy lowering.
This sourceDevelops choice architecture and friction ("sludge") reduction as policy-level activation-energy lowering: defaults, simplification, and removal of small barriers transform thermodynamically favorable but kinetically blocked behaviors. SUPPORTS the claim that Thaler and Sunstein frame choice-architecture frictions as policy-level activation-energy lowering.

- Commitment Device
- Rather than re-litigating temptation at every future juncture — each meal, each market open, each policy meeting, each idle browser tab — the agent makes one binding choice and lets the altered choice architecture carry the rest, freeing cognitive and emotional resources that would otherwise be consumed by continuous vigilance.
This sourceDevelops choice architecture and friction reduction — defaults, simplification, and removal of small barriers; supports the manages-complexity claim that altered choice architecture can carry behavior without continuous vigilance.

- Context-Dependent Preference
- Once one accepts that the ordering has a context argument, "we just showed them the options" describes a specific setting of that argument rather than an abstention from setting it, and the defense that a design was not intended to influence anyone stops being available.
This sourceArgues that every choice environment already has an architecture, so presenting options neutrally is not among the options available to a designer.

- Designed-Out Misuse
- the wrong action is mechanically blocked while the right action is unchanged. Public health policy: reformulation driven by sugar taxes, indoor smoking restrictions, default-opt-in organ donation
This sourceTreats choice architecture and defaults (e.g., default-opt-in organ donation, friction on the harmful path) that channel behavior toward the desired outcome while preserving the legitimate path.

- Framing
This sourceDevelops choice architecture and libertarian paternalism — defaults steer outcomes while preserving formal opt-out freedom.
- Incentive
- In public health it is tobacco and sugar taxes, vaccination subsidies, and conditional cash transfers tying clinic visits to payments.
This sourceDistinguishes the consequence-side payoff lever from menu-side and belief-side (default/salience) levers; basis for public-health incentive design including conditional cash transfers.
- In public health it is tobacco and sugar taxes, vaccination subsidies, and conditional cash transfers tying clinic visits to payments.
- Inversion
- Behavioral economics and policy: Thaler-Sunstein 2008 Nudge explores default-inversion and choice architecture — inverting the default option inverts behavior without changing available choices.

- Mandatory vs. Default Norms
- This division traces to Hart's (1961) jurisprudential separation of primary rules of obligation from secondary rules of recognition, change, and adjudication, which together constitute a legal system's bindingness architecture, and has been generalized by Sunstein and Thaler (2008) into a broader framework of choice architecture spanning law, public policy, and private design.
This sourceGeneralizes mandatory/default architecture into the broader framework of "choice architecture" spanning law, public policy, and private design; develops the libertarian-paternalist position that defaults can steer outcomes while preserving formal opt-out freedom.

- Presupposition Smuggling
- In software defaults, the default setting presupposes the user's wishes, and most users ratify it by inaction.
This sourceShows that default settings presuppose the chooser's wishes and are ratified by inaction by most users.

- Substrate-Cued Behavior Recruitment
- In behavioral economics, default-opt-in recruits enrollment, cafeteria placement recruits healthier choices, and checkout-aisle positioning recruits impulse purchases.
This sourceDevelops choice architecture and the nudge — defaults, placement, and friction that recruit a target behavior — the welfare-aimed specialization of substrate-cued recruitment.

Domain-specific¶
- Friction Budgeting
- One is the variable, the other is the strategy for placing it. Not nudge/sludge alone. The behavioural-economics nudge/sludge tradition is the behaviour-steering slice of the same allocation idea
This sourceThe nudge/choice-architecture programme, in which small features of a choice environment are arranged to steer behaviour predictably.

Mechanisms¶
- Behavioral Prompting
- It draws on choice architecture — the finding that the arrangement of cues and defaults around a decision measurably shifts behavior without changing what's on offer.
This sourceDefines a nudge as an aspect of choice architecture that predictably alters behavior without forbidding options or significantly changing economic incentives.

- Cooling Pause and Evidence Gate
- That makes it the natural home of a cooling-off period,
This sourceThaler and Sunstein present cooling-off periods as delays or rescission windows that let people reconsider heat-of-the-moment decisions before they become final.

- Corrective Feedback Nudge
- Because it only invites
This sourceDefines a nudge as choice architecture that steers behavior without restricting freedom of choice.
- Because it only invites
- Default Enrollment
- The design is a textbook nudge, and its defensibility hinges on the easy opt-out: the very same lever, aimed at the clinic's billing rather than the patient's health — say, defaulting patients into costly add-on services — would be manipulation, not care.
This sourceDefines a nudge as a predictable influence that preserves choice and remains easy and inexpensive to avoid.

- Default Setting Shift
- Its strength is reach at almost no cost: one switch moves a population's behavior while leaving every individual free, which makes it the canonical nudge — a change in choice architecture that alters behavior predictably without forbidding options or changing payoffs.

- Environmental Trigger Removal
- This is the logic of choice architecture and default-setting — the surroundings quietly do the work the actor used to have to do.
This sourceDefines choice architecture as the environment in which choices are made and shows how defaults predictably influence behavior without active choice.

- Infrastructure and Default Redesign
- Choice architecture is the honest name for the lever and the warning about it in one
This sourceDefines nudges as easy and cheap to avoid and argues that some choice architecture, including how options and defaults are presented, is unavoidable.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 21 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
