What it is
Groupthink describes the deterioration of decision quality that occurs when a cohesive group prioritises agreement over accurate appraisal of alternatives. It is not simply conformity pressure - it also involves the self-censorship of individuals who privately hold doubts but do not raise them for fear of disrupting the group or challenging authority. The result is decisions that carry the appearance of consensus without the substance of it. Groupthink is more likely in highly cohesive teams with strong leadership, operating under time pressure or external threat.
Where it shows up
In senior leadership decisions - capital allocation, hiring for key roles, strategic pivots - groupthink produces the most damage. A leadership team that has built strong relational trust can slide into mutual validation without realising it. Dissenting analysis is softened before it is presented, then acknowledged politely and not acted upon. The decision record shows a discussion that happened; the actual disagreement that could have improved the decision never reached the table.
What Rubicon Probity does
When Rubicon Probity reviews a decision record at the Diagnose or Decide stage and finds that all documented inputs point in the same direction with no recorded dissent, it raises a NOTE flag and requests that the record include a documented devil's advocate review or structured pre-mortem before the decision is finalised. The absence of recorded dissent in a consequential decision is itself a signal worth examining.
Detection questions
- Is there anyone in the decision group who privately holds a materially different view - and has that view been documented in the decision record?
- Has a devil's advocate or pre-mortem process been run, and are the outputs included in the evidence base?
- Would the most junior person in the room feel able to raise a fundamental objection to the preferred direction - and what structural mechanisms exist to make that possible?
