What steps can group members take to ward off groupthink?

To ward off groupthink, group members can encourage open dialogue by inviting diverse opinions and actively seeking dissenting views. Establishing a norm where questioning and critical thinking are valued helps create a safe space for all voices. Additionally, assigning a "devil's advocate" role can help challenge prevailing ideas and stimulate discussion. Finally, taking time for reflection and independent thinking before group meetings can ensure that all members come prepared to contribute their perspectives.
