Groupthink

What is Groupthink?

Groupthink is a proposed pattern in which pressure for agreement weakens a group's critical assessment of alternatives and risks. Members may hold back doubts or avoid challenging a decision because disagreement feels unwelcome.

That is more specific than consensus. A group can agree after a thorough discussion. It can also make a bad decision without anyone being afraid to speak.

An example of groupthink

Imagine a team preparing to launch a product. Several members see a serious flaw, but each stays silent because the leader treats objections as disloyalty. The apparent agreement hides concerns that could change the decision. This illustrates the proposed process; it does not explain every failed launch.

Evidence and Criticism

Esser’s 1998 review examines historical case analyses and laboratory tests of groupthink. The full model remains disputed: Fuller and Aldag’s 1998 critique argues that its empirical support is weak and that its assumptions can restrict analysis.

Historical cases, including the Bay of Pigs invasion of Cuba, are often discussed through this lens. But naming a disaster and calling it groupthink is not a demonstration of its cause. The label can become a substitute for investigating what happened.

What to Do with the Idea

Make room for independent views. Examine alternatives, ask what could go wrong, and take objections seriously before committing to a decision. These are useful procedures, even without treating groupthink as a settled diagnosis.

The real question is whether the decision process allows relevant information and disagreement to change the choice.
