Primes¶
- Abilene Paradox
- Structured go-around protocols, where each member states their own view before hearing others, defeat the first-mover problem by removing the option to read the room first. Rotating devil's-advocate roles assign dissent so that no individual bears its social cost.
This sourceAnalyzes group decision pathologies and prescribes remedies including assigning a devil's-advocate role to surface dissent.

- Conformity
- Janis (1982) traced how cohesive policy groups, under conformity pressure, manufacture an illusion of unanimity that drives defective decisions — a domain-specific intensification of the general yielding mechanism.
This sourceDocuments how cohesive policy groups under conformity pressure suppress dissent and manufacture an illusion of unanimity that drives defective decisions. Live-verified.

- Groupthink
- The structural signature is systematic under-weighting of within-group informational diversity, driven by the premature consensus dynamic that overrides informational aggregation.
This sourceHoughton Mifflin. Revised/expanded edition documenting how cohesion and conformity pressure suppress dissent; adds Watergate and refines the model and remedies.

- Information Cascade
- Breaking this requires making private doubts visible (anonymous polling, pre-decision blogging, required dissent), not just exhorting people to speak up.
This sourceHoughton Mifflin. Foundational groupthink monograph: documents how group cohesion and conformity pressure suppress dissent in policy decisions, providing the psychological-failure contrast to rational-cascade structural failure.

Mechanisms¶
- Devil's Advocate Role
- Its strength is that it breaks the spell of easy agreement by putting a sanctioned opponent in the room — a direct structural answer to groupthink, the drift toward concurrence that Irving Janis diagnosed and for which an assigned critical evaluator was among his recommended correctives.
This sourceTreats an assigned critical evaluator or devil's advocate as a sanctioned structural check on groupthink and concurrence seeking.

- Early Warning Forum
- Its failure mode is groupthink in reverse dress — a forum that looks deliberative but converges on a senior member's read because dissent is socially expensive.
This sourceDescribes direct pressure on dissenters and self-censorship as defining symptoms of groupthink.

- Independent Facilitator
- It operationalizes a classic remedy for suppressed dissent — keeping the leader from steering the deliberation — which Irving Janis recommended precisely to stop a group from converging on the leader's preference.
This sourceJanis recommends leader impartiality and delayed preference disclosure to reduce authority-driven concurrence and suppressed dissent.

- Paradox Workshop
- Its guard against the classic risk is deliberate: dissent is invited rather than smoothed, so the session does not manufacture a false consensus.
This sourceDeliberate critical evaluation, devil's advocacy, and a second-chance meeting invite dissent and counter premature or false consensus.

- Red-Team Stress Exercise
- Its counter to groupthink is structural: a sanctioned dissenter is licensed to say the emperor has no clothes.
This sourceRecommends a formally assigned devil’s advocate as a structural safeguard against groupthink and premature concurrence.
- Its counter to groupthink is structural: a sanctioned dissenter is licensed to say the emperor has no clothes.
- Reflective Belief Dialogue
- Its strength is breaking the conformity spiral that produces confident group error: a protected, rotating challenger is the practical antidote to groupthink, in which the desire for harmony suppresses the very objections that would have caught the mistake.
This sourceDescribes groupthink as concurrence-seeking that suppresses doubts and objections and degrades critical judgment.

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? Not recorded. Neither this nor any other of the 10 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.
