What does the concept of 'groupthink' imply about individual attitudes within a group?

The concept of 'groupthink' pertains to a situation where individuals in a cohesive group prioritize consensus and harmony over critical thinking and individual dissent. This results in an environment where the desire for group agreement leads to a suppression of dissenting viewpoints and a lack of alternative perspectives being considered. Members may conform to what they perceive as the prevailing opinion, even if they harbor personal doubts or reservations. This process tends to overlook potential risks or flaws in decision-making, leading the group to make less informed and possibly suboptimal choices.

In contrast, the other options suggest dynamics that are contrary to the nature of groupthink. Amplification of individual opinions, welcoming of disagreement, or encouragement of diverse thought would instead foster a setting where critical discourse thrives, and where differing viewpoints contribute to a richer understanding and better decision-making outcomes. However, in groupthink scenarios, those principles are typically sidelined in favor of maintaining group cohesion.
