A salient event concentrates public attention. Attention is exposure, not agreement, recruitment, membership, or commitment.
CD-05 Comparative dossier
Visibility can cascade faster than a movement can become an organization.
Catalytic events can reorganize attention, reveal hidden preferences, lower participation thresholds, spread tactics, and recruit people through social networks. But attention, attendance, imitation, identity, ideology, organization, and durable participation are different outcomes—and they do not rise together automatically.

Research question
What actually spreads after a catalytic event—and what only looks as if it spread?
The owner-supplied reports correctly treat catalytic events as triggers whose effects depend on pre-existing conditions, hidden preferences, networks, organizations, and institutional responses. Independent verification supports that broad interaction model while narrowing the strongest claims. A salient event can change what people know about one another, change the perceived costs of participation, recruit previously disconnected people, or accelerate an existing tactic. None of those mechanisms by itself establishes ideological conversion, a coherent collective identity, or durable organization.
Movement boundary: this is comparative evidence. It does not establish that the Unprogrammable movement has experienced a catalyst, is rapidly growing, has a measurable network core, possesses a common ideology, or has converted online visibility into durable organization.
Mechanism stack
People must decide what the event means. Existing narratives, identities, institutions, and media frames shape whether the event is read as accident, injustice, opportunity, threat, or proof of a broader pattern.
Visible dissent can reveal that previously private or muted preferences are more widely shared than people believed. A cascade may therefore expose latent support rather than create it.
Seeing others act can reduce perceived risk or raise expected efficacy. Small changes around participation thresholds can produce nonlinear aggregate change.
Organizations, friends, weak ties, broadcast messages, and digital networks can put people in contact with a movement opportunity. Exposure still does not guarantee participation.
High-cost or identity-relevant behavior may require confirmation from multiple contacts rather than one weak exposure. Network structure therefore changes which forms of behavior can spread.
Movements can copy repertoires, slogans, occupations, encampments, hashtags, or organizational templates. A tactic can spread even when it is ineffective.
Sympathy must still pass through motivation, recruitment, logistics, risk, time, resources, and competing commitments before becoming action.
Repeated interaction can help produce a collective “we,” but collective identity is a distinct process, not a synonym for exposure, attendance, or reposting.
Membership, leadership development, routines, governance, resource custody, conflict resolution, and succession convert bursts of action into continuing capacity.
Authorities, media, opponents, allies, and organizations react to the mobilization. Those responses change risks, narratives, coalition boundaries, and later participation.
A movement can be highly visible at one moment yet leave little durable organization; a quieter formation can persist through institutions, relationships, and routines after public attention fades.
What the checked evidence supports
Twelve findings that separate cascade from consolidation.
Catalysts reorganize information before they necessarily change preferences
Kuran’s preference-falsification model explains how public opposition can grow explosively when people learn that private dissent is more common than public behavior suggested. The mechanism is preference revelation and changing perceived risk—not a claim that one event instantly created a new ideology.
Small threshold differences can generate large macro differences
Granovetter’s threshold model shows why groups with similar average dispositions can produce very different collective outcomes. This makes sudden mobilization compatible with gradual or hidden micro-level conditions and cautions against reading the final crowd size back into a uniform set of individual motives.
Some events become historically transformative only through sequences of interpretation and response
Sewell’s eventful sociology treats transformative events as unfolding sequences that alter structures. The analytical object is therefore not merely “the spark” but the cascade of reactions, reinterpretations, institutional moves, and subsequent events that follow it.
Moral shock can recruit beyond pre-existing activist networks
Jasper and Poulsen show that emotionally and morally salient messages can recruit strangers in some movements rather than operating only through prior activist ties. That does not make moral shock universally sufficient; it identifies an additional recruitment pathway.
Sympathy is not participation
Klandermans and Oegema separate mobilization potential, recruitment targeting, motivation, and barriers to participation; later work examines erosion and nonconversion among sympathizers. Large attentive or sympathetic publics can therefore coexist with a much smaller active participant population.
High-risk participation often depends on embeddedness, not exposure alone
McAdam’s Freedom Summer research and McAdam–Paulsen’s later specification of network effects show that prior activism, organizational affiliations, tie content, and competing social pressures help explain who follows through on costly participation. Network exposure is not a generic force with one effect.
Tactics can diffuse without proving that they work
Soule documents tactical diffusion among similar institutions and, in later work, shows an unsuccessful protest innovation spreading partly because media and cultural framing made it appear successful. Copying a tactic is evidence of diffusion, not evidence of strategic effectiveness or ideological convergence.
Organizations, social ties, and news media can all carry diffusion
Andrews and Biggs find multiple channels in the spread of the 1960 sit-ins, while Strang and Soule’s review emphasizes both structural and cultural pathways. “Viral” diffusion is therefore too narrow when organizations and legacy media are part of the transmission architecture.
Behavioral diffusion can require reinforcement from multiple sources
Centola and Macy’s complex-contagion theory, reinforced by Centola’s online experiment, shows why socially costly behavior may need redundant confirmation rather than a single weak tie. Information can spread rapidly while behavior spreads only where network reinforcement is sufficiently dense.
Digital networks can change recruitment and coordination without making central influencers sovereign
González-Bailón and colleagues identify online recruitment cascades; Barberá and colleagues highlight the aggregate role of a critical periphery; Steinert-Threlkeld finds important mobilizing roles for network peripheries. Together they challenge a simple influencer-centric model.
Online social influence can affect behavior, but digital traces do not establish durable commitment
Bond and colleagues provide randomized evidence that social messages can affect political mobilization, while Tufekci and Wilson and Steinert-Threlkeld et al. link digital communication to protest information, logistics, and offline activity. These studies illuminate mobilization mechanisms, not long-run membership or ideological conversion.
Mobilization can scale faster than organization
Bennett and Segerberg describe connective-action formations that coordinate with comparatively light formal organization. Margetts and colleagues emphasize the volatility and frequent failure of online mobilizations. A 2026 Harvard working paper by McKenna adds provisional long-run evidence that large digital-era mobilizations can leave weak organizational afterlives unless participants build membership, leadership, and institutional capacity.
Causal audit
Six causal separations prevent “virality” from becoming an explanation for everything.
Attention ≠ persuasion. A spike in searches, mentions, views, or news coverage shows salience. It does not establish attitude change.
Preference revelation ≠ preference creation. A public cascade can expose beliefs that were already held privately.
Recruitment exposure ≠ participation. People can hear about an action, agree with its goals, and still decline because of risk, time, resources, family obligations, competing ties, or doubts about efficacy.
Tactical diffusion ≠ ideological diffusion. Groups can copy a tactic, slogan, or communication format without adopting the same worldview or institutional goals.
Participation ≠ collective identity. One-time attendance or low-cost digital action does not prove a durable sense of shared “we.” Collective identity has its own construction, boundaries, narratives, and maintenance.
Mobilization ≠ organization. A crowd can assemble before it develops membership structures, governance, leadership pipelines, durable resources, conflict-resolution procedures, or succession. The existence of activity is therefore not itself evidence of organizational depth.
Counterevidence and limiting cases
Diffusion can spread failure
Soule’s unsuccessful-innovation study is a direct warning against equating copied tactics with effective tactics. Media constructions and cultural fit can sustain imitation even when outcome evidence is weak.
Sympathizers frequently do not convert
Participation research shows attrition between agreement, recruitment, motivation, and action. A large “potential” population is not the same thing as an active movement.
Centrality is not monopoly
Critical-periphery and peripheral-mobilization studies show that aggregate reach can depend on many less-central actors and that protest can emerge without a single network core controlling mobilization.
Online networks can be fragmented
Digital visibility does not guarantee efficient brokerage, shared frames, or sustained coordination. Networked communication can remain fragmented even when the campaign is highly visible.
Collective identity cannot be read from hashtags
Polletta and Jasper’s review treats collective identity as a substantive movement process. Shared labels and symbols can contribute to identity work, but use of the same language is not sufficient evidence that users share boundaries, obligations, or strategic commitments.
Afterlives can be weaker than peaks
Political Turbulence emphasizes unstable and often unsustainable digital mobilization. McKenna’s 2026 working paper similarly argues that visible protest activity can outpace the organizational capacities needed for long-run influence; because it is a working paper, the dossier treats that claim as current but provisional.
Why this matters for unprogrammability
The thing that spreads can change while it is spreading.
This mechanism cluster is central to unprogrammability because networked collective processes are recursively observed and modified by their own participants. A catalytic event changes attention; attention changes perceived support; perceived support changes who joins; new participants alter tactics and frames; institutional responses alter risk and legitimacy; copied practices mutate across settings; and organizations attempt to stabilize what emerged under very different conditions.
That means a movement can grow while simultaneously changing its composition, meaning, and capacity. Rapid diffusion is therefore not evidence that one center successfully “programmed” the process. But the opposite inference is also invalid: distributed diffusion does not prove the absence of leadership, organizations, brokerage, infrastructure, or unequal influence.
For the Unprogrammable movement itself, this becomes an empirical program: document which ideas, practices, labels, and relationships actually spread; identify whether they are copied, reinterpreted, contested, or abandoned; and measure whether repeated participation produces durable relationships and institutions rather than inferring depth from visibility.
Translation into the Living Movement Study
Measure the sequence, not just the peak.
What event, publication, conversation, or encounter first made the project salient? Distinguish discovery from agreement.
Did people already hold the relevant view before publicly expressing it? What changed the perceived cost or benefit of saying so?
Did participation arrive through a friend, organization, public article, search engine, social platform, event, or another project in the Ghrisx ecosystem?
How many independent signals or trusted contacts were needed before someone participated? Do high-cost actions require denser reinforcement?
Which practices are copied between participants or groups, and which are independently invented? What evidence exists that copied practices actually work?
When does “Unprogrammable” become more than a descriptive label? Look for shared boundaries, narratives, mutual obligations, disagreement norms, and repeated self-identification.
Measure recurring roles, stewardship, infrastructure, resource custody, decision procedures, conflict resolution, leadership development, succession, and institutional memory.
Track return participation and relationships across months and years rather than treating one traffic or attendance spike as growth.
Measurement rule
Do not infer movement membership, ideology, conversion, organizational commitment, or participant demographics from follows, likes, reposts, hashtags, referral URLs, geolocation, follower counts, or network centrality. Public digital traces can describe communication patterns only within the limits of consent, privacy, platform sampling, and construct validity.

Published comparative synthesis, not a finding that an online audience is a movement.
Author: Unprogrammable.org Editorial Project.
Publication / revision: 2026-09-20.
Review: editorial claim-level source verification; this synthesis has not been independently peer reviewed.
Scope limits: the source set spans different countries, eras, platforms, movements, outcomes, and research designs. Digital-network studies are especially vulnerable to platform-specific sampling, observability, and selection problems. Classic threshold and preference-revelation models identify mechanisms; they do not prove those mechanisms operate in every protest cascade.
Claims explicitly not adopted: “one catalytic event creates revolutionary preferences”; “virality proves recruitment”; “reposting proves ideological conversion”; “a copied tactic is effective”; “central influencers control diffusion”; “leaderless visibility means organization is unnecessary”; “a large crowd proves durable movement membership”; or “online network structure reveals the true structure of the wider movement.”
Revision trigger: revise if cited work is corrected or retracted, stronger causal studies materially alter the mechanism distinctions, the 2026 working paper changes through peer review, or direct movement evidence supports or contradicts the proposed pathways.
