Keep disconfirming evidence in the room
High-stakes groups need procedures that keep disconfirming evidence, alternatives, and dissent available before concurrence becomes commitment
Premise
Executive groups exist partly to pool information and challenge assumptions. Under pressure, however, preserving agreement can become more important than realistic appraisal. Warnings are rationalized, dissenters are pressured, alternatives disappear, and silence is recorded as consent. The team may look aligned precisely when its decision process has stopped using its diversity.
Irving Janis’s Groupthink model gives leaders a preventive language for this risk. The modern theory is Janis’s 1971–1972 formulation, although William Whyte coined the word in 1952. Groupthink is not a synonym for cohesion, loyalty, consensus, or a bad outcome. It is a proposed pattern linking concurrence seeking with conditions, communication symptoms, and defective decision procedures.
