Groupthink

A cohesive team may mistake early agreement for a well-tested decision.

01 / PLAINLY

What it means, plainly

Groupthink is a debated theory of premature consensus, pressure, and evaluation failures in some teams.

02 / CONTEXT

A little more

Groupthink is a theory of premature consensus, pressure, and evaluation failures in some decision-making groups. Historical cases are influential, but definition, measurement, and predictive power have been criticized.

03 / WHY IT MATTERS

Why it matters

Naming alternatives and objections before favoring one option may reveal agreement that has not yet been tested.

04 / EXAMPLE

A familiar example

Leaders read few objections as unanimity after the chair announces a favored option at the start.

05 / LIMIT

What it does not mean

Cohesion does not always cause poor decisions, and naming groupthink after failure does not explain the process.

06 / NOTICE

Notice it in your day

Before a small decision, request two alternatives and record one objection to each without making one person carry all dissent.

FINAL NOTE

The idea worth keeping

Request alternatives before favoring one and record objections without making one dissenter carry the whole case.
