Groupthink Detection
Updated 2026-08-13
INTRODUCTION
English translation pending.
CORE DEFINITION
The method applies a checklist of symptoms to identify groupthink in a decision-making body: over-unanimity, direct pressure on dissenters, illusions of invulnerability and morality, rationalization of warnings, and self-censorship. The core claim is that a team that feels too harmonious may be smothering real objections, so apparent consensus should itself be treated as a signal to check. The key qualification is that the check must occur before the decision is locked, not in the post-mortem.
SCAFFOLDING EFFECT
Reduce cognitive load
- Audit apparent harmony: treat suspicious unanimity as a symptom to investigate. - Run the symptom checklist: work through the markers before a decision is locked. - Protect the dissenter: make it safe to object so real objections reach the room.
Anchor fast decisions
In a cohesive group, belonging feels safer than accuracy, so members withhold objections and read each other's silence as agreement; the shared illusion of consensus then freezes the group around an untested position. Naming the symptoms in advance gives members a vocabulary for the pressure, and checking before the lock exposes the silence as suppressed conflict.
