As their first line of defense against groupthink, leaders need to learn to recognize latent discontent, paying special attention to body language: furrowed brows, crossed arms, or curled-up defiance. To bring disaffected people back into the discussion, it may be best to call for a break, approach dissenters one by one, encourage them to speak up, and then reconvene. GM's Alfred Sloan was famous for this approach, which he would introduce w1th the following speech:" I take it we are all in complete agreement on the decision here. Then I propose we postpone further discussion of the matter until our next meeting to give ourselves time to develop disagreement and perhaps gain some understanding of what the decision is all about.""Because the meeting is the wrong place to object, we don't walk out of the room as a unified group;" Instead, they would reopen the debate during implementation, delaying important initiatives by many months.
