When a group is engaged in groupthink, how can you cause the group to be more open to your dissenting comments?
1) Use a high-context speaking style.
2) Begin with a smile and a phrase such as, "Excuse me, but"
3) Send an email or text to the group members during the meeting expressing your dissent in writing.
4) Wait until after the meeting, talk to the leader, then at the next meeting add, "The leader and I spoke earlier, we think"
5) Use information from a recognized source.
