Which one of the following ways is NOT suitable to counteract groupth…

The correct answer is Option (4) → Discouraging critical thinking

In groupthink a group’s concern for unanimity overrides a realistic look at its choices: no one voices doubt, and the group drifts out of touch with reality. Every remedy therefore brings fresh views and disagreement back into the group.

Option (1) Encouraging members to seek feedback from trusted others — Suitable (Incorrect). Feedback from trusted people outside the group lets members test the decision against views that are not shaped by the group’s wish for agreement.

Option (2) Encouraging groups to present alternative courses of actions — Suitable (Incorrect). Groupthink is likely in groups with no tradition of considering alternatives. Asking for alternatives breaks this habit.

Option (3) Inviting outside experts to evaluate the group’s decisions — Suitable (Incorrect). Groupthink grows in groups isolated from outsiders. An outside expert brings in the cues from the real world that such a group tends to ignore.

Option (4) Discouraging critical thinking — Not suitable (Correct). The first remedy is to encourage and reward critical thinking and even disagreement among members. Discouraging it would strengthen the false consensus that produces groupthink.
