GROUPTHINK<\/a> is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. The concept was first extensively researched by IRVING-JANIS<\/a> in 1972. According to his research, members of a cohesive group try to minimize conflict and reach a consensus without critical evaluation of alternative viewpoints by actively suppressing dissenting ideas and by isolating themselves from outside influences.<\/p> Janis identified several symptoms of GROUPTHINK<\/a>, including an illusion of invulnerability, collective rationalization, and a belief in the inherent morality of the group. These factors can lead to disastrous outcomes in high-stakes environments, such as the BAY-OF-PIGS-INVASION<\/a> or the CHALLENGER-DISASTER<\/a>. More information on the psychological mechanisms involved can be found through the American Psychological Association<\/a> and Britannica<\/a>.<\/p> To mitigate the risks associated with SOCIAL-PSYCHOLOGY<\/a> biases like this, organizations often implement strategies to encourage CRITICAL-THINKING<\/a> and assign a \"devil's advocate\" to challenge the majority opinion. Understanding COGNITIVE-BIAS<\/a> and its role in TEAM-DYNAMICS<\/a> is essential for effective leadership and organizational health.<\/p>
