Answer: The answer is groupthink.
When members of a group give priority to the cohesiveness of the group over the facts of a situation, they are engaging in what social psychologists call groupthink.
Explanation:
Groupthink occurs when a group makes poor decisions by ignoring valid alternatives or substitutes in the face of internal pressures from the group. This may be as a result of a particular agenda or because group members value harmony and orderliness above logical thinking. In group thinking, there is no rule for making decisions.
