Define groupthink and list four common symptoms

What will be an ideal response?

Answer: A good answer will include the following key points.
? Groupthink is the tendency for members of a group to think alike for the sake of harmony and to suppress disagreement among their members.
? Common symptoms of groupthink are:
? An illusion of invulnerability—the group believes it can do no wrong and is 100 percent correct in its decisions.
? Self-censorship—dissenters decide to keep quiet rather than make trouble, offend their friends, or risk being ridiculed.
? Pressure on dissenters to conform—the leader teases or humiliates dissenters or otherwise pressures them to go along.
? An illusion of unanimity—by discouraging dissent and failing to consider alternative courses of action, leaders and group members create an illusion of consensus.
