Final answer:
Groupthink can be prevented by a directive leader who makes their position clear, invites outside experts for critique, and maintains high morale among group members.
Step-by-step explanation:
Groupthink can be prevented by a leader who:
- Is a directive and makes his or her own position clear from the start. By clearly expressing their opinions, leaders can encourage group members to express their own thoughts without fear of disagreement.
- Invites outside experts to critique a group's developing plans. This allows for fresh perspectives and helps avoid the tendency for the group to become isolated and resistant to new viewpoints.
- Tries to maintain high morale among group members. When group members feel positive and supported, they are more likely to engage in critical thinking and challenge the consensus if necessary.
