Final answer:
Groupthink is the negative team process where highly cohesive groups prioritize unanimity over critical thinking, leading to poor decisions.
Step-by-step explanation:
The negative team process that occurs when groups are highly cohesive, under considerable pressure to make a quality decision, and strive for unanimous agreement, is known as groupthink. Groupthink is characterized by the modification of the opinions of group members to align with what is perceived as the group consensus, often leading to poor decision-making. This phenomenon is especially likely when the group is highly unified or isolated from opposing viewpoints. There are several symptoms of groupthink, such as the illusion of invulnerability, belief in the inherent morality of the group, and self-censorship. It jeopardizes the evaluation of alternative solutions and may culminate in a decision that is not optimal or even harmful. To prevent groupthink, strategies such as seeking outside opinions, private voting, and developing contingency plans are suggested.
