Answer: Groupthink
Step-by-step explanation:
Groupthink is known to occur when a group of people come together, decide and reach general agreement in decision making. Group opinion is accepted and acknowledged which might not be valid or right instead of individual’s opinion without thinking of the outcome or effect of the decision. Also, members in this group tend to be of the same background and there are no laid down rules for decision making process. Thus, it happens in groups where the peace and unity of the group is of optimum priority or importance.
