Which of the following best describes "groupthink"?

Groupthink is best described as a practice that encourages conformity in decision-making. This phenomenon occurs when a cohesive group prioritizes consensus and harmony over critical analysis and independent thought. Members may suppress dissenting viewpoints, leading to a lack of creativity and reduced problem-solving capabilities. This mode of decision-making often results in poor outcomes, as critical perspectives that could challenge the status quo are overlooked.

In contrast to the other choices, which promote independent thinking, eliminate biases, or gather diverse opinions, groupthink diminishes these elements. Thus, the tendency to seek agreement can create an illusion of invulnerability and hinder the group's overall effectiveness. Understanding groupthink is crucial for leaders and teams to foster an environment where diverse opinions are valued, ultimately enhancing decision-making quality and encouraging innovation.
