How is "groupthink" best defined?

Groupthink is best defined as the desire for harmony within a group that results in poor decision-making. This phenomenon occurs when the members of a group prioritize consensus and cohesion over critical evaluation of alternative ideas or viewpoints. As a result, the group may overlook important information, dismiss dissenting opinions, or fail to consider the potential consequences of their decisions, often leading to suboptimal outcomes.

In the context of groupthink, the pressure to conform and maintain group solidarity can stifle individuality and creativity, causing members to suppress their doubts or disagreements. This can lead to decisions that are not well thought out or reflect a lack of thorough analysis—a hallmark of groupthink. Understanding this concept is critical in recognizing how group dynamics can influence group effectiveness and decision-making processes.
