Which concept involves heavy reliance on group consensus in decision-making?

The concept that involves heavy reliance on group consensus in decision-making is groupthink. This phenomenon occurs when a cohesive group prioritizes harmony and consensus over critical analysis and independent thought. As a result, group members may suppress dissenting viewpoints or overlook potential risks in order to maintain uniformity of opinion.

In groupthink, the desire for consensus can lead to poor decision-making outcomes because vital information and alternative perspectives are disregarded. Members may feel pressure to conform to the prevailing viewpoint, which stifles creativity and critical discussion. This dynamic is particularly problematic in high-stakes situations where careful deliberation is essential.

Understanding groupthink is crucial in behavioral science as it highlights the importance of encouraging open dialogue and fostering an environment where dissent can safely occur, ultimately leading to better decision-making processes and outcomes.
