Stop-or-Switch Rule¶
Procedure — instantiates Receptivity-Window Intervention Design
A pre-set rule that fires on closing or refractory signals to pause, de-escalate, defer, or switch — protecting a substrate that has stopped being receptive.
The Stop-or-Switch Rule works at and after the window's close, on an active intervention, to break it off before continued pressure does harm. Its defining idea is that closure must be able to override momentum and sunk cost: the moment the substrate shows it is saturating, fatiguing, resisting, or entering a refractory state, the rule fires — pause, de-escalate, defer, or switch to a fallback — regardless of how much has been invested or how badly the actor wants to finish. It is a committed disengagement rule, agreed before action so that stopping is not a live negotiation under the pull to push on. It neither prepares the substrate nor stabilizes what was gained; it is the brake, and only the brake.
Example¶
A mobile-app team is onboarding new users with a sequence of setup nudges — permission prompts, feature tips, a follow-up email cadence. Early in the window, users are receptive: they tap through, enable notifications, complete setup. But the app's own signals start to turn: prompt dismissals climb, the notification-disable rate ticks up, session length after a nudge drops. The window is closing into reactance. The Stop-or-Switch Rule is a committed threshold on those signals: when the dismissal rate crosses its line, or a user enters a defined quiet period after disabling notifications (a refractory marker), the sequence halts for that cohort. It does not keep pushing the remaining tips; it switches to a low-touch fallback — a single in-context hint shown only if the user reopens the relevant screen — and defers the rest until fresh engagement signals reappear. The outcome is that the team stops converting a receptive moment into an irritated unsubscribe, because the brake was set before anyone was tempted to "just send one more."
How it works¶
The distinctive machinery is a pre-committed disengagement trigger with three moves built in. A closing-boundary condition defines, in advance, the signals that mean the window has shut — saturation, fatigue, defensiveness, indifference, or lock-in into another path. A refractory marker names the post-closure state during which further action is not just useless but harmful, so the rule enforces a cooling interval rather than an immediate retry. And a fallback mode specifies the graceful alternative — pause, de-escalate, defer, or switch — so that "stop" is a defined next action, not a void. Because all three are set before the action starts, the rule can fire against the actor's own momentum.
Tuning parameters¶
- Closing sensitivity — how faint a closure signal trips the rule. Sensitive stops early and protects the substrate but forfeits late window value; dull stops late and risks harm.
- Refractory length — how long the enforced cooling interval runs before any retry. Longer fully protects recovery but may miss a genuine reopening.
- Fallback aggressiveness — whether the rule pauses, de-escalates, defers, or hard-switches. Softer preserves the relationship; harder cuts losses faster.
- Override friction — how hard it is to countermand a fired stop. High friction prevents sunk-cost push-through; low friction allows a warranted continue but invites abuse.
- Re-arm condition — what fresh signal is required before action may resume after a stop, guarding against premature re-engagement.
When it helps, and when it misleads¶
Its strength is that it prevents overuse after closure — the failure in which continued pressure on a spent substrate produces fatigue, saturation, or harm. It guards specifically against psychological reactance[n1], the pushback a receiver mounts when pressed past receptivity, by making disengagement a rule rather than a judgment made in the grip of momentum.
Its failure mode is a closing threshold set too dull, so the rule fires only after the substrate is already harmed — or, oppositely, so twitchy that it aborts good interventions at the first noisy dip. The classic misuse is building the rule and then routinely overriding it under sunk-cost pressure, which reproduces exactly the overrun it was meant to prevent. The guarding discipline is to keep override friction high, to enforce the refractory interval honestly, and to require a genuine re-arm signal before resuming rather than retrying on hope.
How it implements the components¶
closing_boundary_condition— it defines, in advance, the signals that mean the window has shut and makes crossing them fire the halt.refractory_or_recovery_marker— it names the post-closure state and enforces a cooling interval in which further action is withheld.fallback_or_deferral_mode— it specifies the graceful alternative to pushing on: pause, de-escalate, defer, or switch.
It does NOT prepare or raise the substrate beforehand (readiness_priming_pathway, legitimacy_and_consent_guardrail) — that is its nearest twin, Pre-Window Priming Protocol; and it does NOT stabilize what was taken up (post_window_consolidation_pathway) — that is Post-Window Consolidation Review. The one-sentence separation from the twin: the Stop-or-Switch Rule halts a no-longer-receptive substrate as the window closes, while priming raises a not-yet-ready substrate before it opens — opposite ends of the timeline, opposite directions of force.

Editorial Notes¶
Form Classification¶
Form family: Rule, Policy & Commitment
Rationale: Stop-or-Switch Rule operates as a standing rule, threshold, contractual commitment, or policy constraint governing future conduct because it a pre-set rule that fires on closing or refractory signals to pause, de-escalate, defer, or switch — protecting a substrate that has stopped being receptive.
Independent corroboration: The frozen evidence defines Stop-or-Switch Rule as 'A pre-set rule that fires on closing or refractory signals to pause, de-escalate, defer, or switch — protecting a substrate that has stopped being receptive', so its operative form is Rule, Policy & Commitment.
Nearest alternative: Protocol, Workflow & Routine — Stop-or-Switch Rule includes features of a repeatable ordered procedure or handoff sequence that coordinates action, but its defining operation is a standing rule, threshold, contractual commitment, or policy constraint governing future conduct.
Review outcome: Independent reviewer agreement; medium confidence.
Origin Attribution¶
Primary origin: Medicine & Healthcare
Origin pattern: Convergent development
Present-day reach: Universal
Rationale: Preset de-escalation on refractory response resembles adaptive treatment rules.
Related originating lineages:
- Engineering & Design — Fallback modes protect a substrate.
- Psychology — Receptivity and overload shape stopping.
Review resolution: The blind reviewers agree that medicine_healthcare is the primary origin and differ only on alternate origin disagreement, origin mode disagreement, encyclopedia synthesis disagreement. I preserve every independently explained alternate from both records rather than imposing a numeric cap. I retain convergent because the combined evidence shows independent disciplinary development. The broader reach of universal records portability separately from historical provenance; encyclopedia_synthesis=true preserves the affirmative synthesis judgment where either reviewer identified one.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Reconciled after independent review; high confidence.
Notes¶
[n1] Psychological reactance (Brehm) — the motivational pushback a person mounts when they feel their freedom is being pressured, which turns further persuasion counter-productive. It is the human form of a window closing into resistance, and the reason the stop rule must be able to fire against the actor's own urge to press on. ↩
