Answer:
Group think
Step-by-step explanation:
Group think is a physiological term used to describe how a group of people make decisions which can be irrational all for the harmony or interest of the group.
People see themselves as one when they group think, without even considering the objectives of such thinking. An illustration can be a group of company that isolates itself and do not interact with the business world, they make decisions on their own without considering external influences.
From the scenario in the question, the Managers are concerned about an agreement among them rather than assessment the situation accurately. This is a perfect case of Group think, they value their unity more than objectivity.
