Primes¶
- Activation Energy
- Granovetter's (1978) threshold models of collective behavior demonstrate exactly this kind of counterfactual transfer—heterogeneous individual thresholds yield wildly different aggregate outcomes from similar average preferences.
This sourceFoundational threshold model: heterogeneous individual barriers to participation generate collective tipping points and show that small differences in threshold distributions produce qualitatively different aggregate outcomes. SUPPORTS the cross-domain counterfactual-transfer claim about threshold models.

- Broken Windows Theory
- This is the same algebra as an epidemic threshold (\(R_0\) crossing one) and a ferromagnetic transition, which is why "fix the first window fast" is structurally privileged: it is an intervention on \(r\), the parameter that sets where the threshold sits.
This sourceFormal threshold/tipping-point model where each actor's choice depends on how many others have already chosen — the bistable, density-threshold algebra (same shape as an epidemic R0-crossing) underlying the broken-windows cascade.

- Collective Efficacy
This sourceFoundational threshold model showing how heterogeneous individual participation barriers generate collective tipping points and qualitatively different aggregate outcomes.
- Critical Mass
- The same parameter that governs whether an epidemic grows governs how much vaccination suffices to extinguish it. Sociology and collective action: A movement, norm, or protest becomes self-perpetuating once enough early participants lower the cost (or raise the expected payoff) of joining for the next, so that each joiner recruits, on average, at least one more.
This sourceFoundational threshold model: heterogeneous individual barriers to participation generate collective tipping points where, once enough others have joined, net benefits exceed net costs for the next actor—directly supporting the claim that a movement self-perpetuates once early joiners lower the cost for the next.

- Herding Behavior
- Granovetter (1978) formalized this threshold mechanism in his classic American Journal of Sociology paper on threshold models of collective behavior.
This sourceFoundational threshold model: heterogeneous individual barriers to participation generate collective tipping points and demonstrate that small differences in activation energy distributions produce qualitatively different aggregate outcomes—a canonical case of cross-domain counterfactual transfer.

- Information Cascade
- Sociology & anthropology: Fashion fads, consumer product adoption (why certain brands dominate), belief propagation in organizations (conspiracy theories, organizational myths), religious conversion cascades, dynamics Granovetter (1978) modeled in his threshold theory of collective behavior.

- Micro Macro Linkage
- Threshold models transfer from riots to social-media cascades, the downward edge of visible peer behavior now mediated by platform algorithms, which thereby become a policy lever.
This sourceThreshold models linking individual decision thresholds to aggregate cascade outcomes, transferring from riots to broader collective behavior.

- Nucleation
- Sociology and innovation adoption: early adopters as nucleation seeds in diffusion of innovations; threshold-model and minority-influence accounts of seed-cluster sizes required to nucleate cascading adoption; revolutions ignited from small mobilised cores.
This sourceThreshold model in which a seed cluster above a critical size nucleates a cascade of adoption (riots, innovation), the sociological instance of critical-nucleus reasoning.

- Percolation Threshold
- Preference Falsification
- Each agent \(i\) privately opposes the regime but will voice that opposition publicly only if the perceived number of fellow dissenters already visible exceeds a personal threshold \(\theta_i\) — the point at which the safety of numbers outweighs the expression cost.
This sourceIntroduces threshold models of collective behavior in which each agent acts only once visible participation exceeds a personal threshold.

- Private-Public Preference Divergence
- Let a population of \(N\) agents each privately oppose some position X — the first-order distribution is "nearly all privately reject X."
This sourceThreshold model in which each agent acts only when visible participation crosses a personal threshold, producing self-consistent low-participation equilibria and sudden cascades.

- Segmentation and Boundary Drawing
- This connects to reasoning about threshold effects, tipping points, discontinuous transitions, and the structure of categorical systems, formalized in Granovetter's (1978) threshold models of collective behavior where small shifts in the distribution of individual thresholds produce qualitatively different aggregate outcomes.

- Strategic Complementarity
- Norms and protests: each additional participant lowers personal risk and raises the legitimacy of joining, producing regime-toppling cascades like 1989 and the Arab Spring.

- Threshold
- The launch strategy is specifically threshold-informed: seed the platform to cross the critical-mass threshold, often through subsidies, founders' networks, or geographic focus that concentrates participants locally—a dynamic Granovetter (1978) modeled formally in his threshold-models account of collective behavior, where individual adoption thresholds aggregate into a tipping-point function for the whole population.

- Threshold-Driven Order Emergence
- Internal analysis using a threshold-driven-order-emergence frame (Granovetter 1978 threshold model) reveals that the coalition is at 42% of target supporter-count for critical-mass policy adoption, with empirical research indicating a ~50% threshold for municipal-council voting shift.

- Tipping Points (or Phase Transitions)
- Hysteresis varies: norm reversions may require threshold-crossing in reverse (not guaranteed), and social "memory" (historical precedent) affects regime stability.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 16 citations of this work carries a recorded support check.
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.
