Episode 120: The Causes of Groupthink

Keep Moving Forward

Taken from the Wiki Irving Janis identified three antecedent conditions to groupthink:: High group cohesiveness: Cohesiveness is the main factor that leads to groupthink. Groups that lack cohesiveness can of course make bad decisions, but they do not experience groupthink. In a cohesive group, members avoid speaking out against decisions, avoid arguing with others and work towards maintaining friendly relationships in the group. If cohesiveness gets to such a level that there are no longer disagreements between members, then the group is ripe for groupthink.Deindividuation: Group cohesiveness becomes more important than individual freedom of expression.Illusions of unanimity: Members perceive falsely that everyone agrees with the group's decision; silence is seen as consent. Janis noted that the unity of group members was a mere illusion. Members may disagree with the organization's decision, but go along with the group for many reasons, such as maintaining their group status and avoiding conflict with managers or workmates. Such members think that suggesting opinions contrary to others may lead to isolation from the group.Structural faults: The group is organized in ways that disrupt the communication of information, or the group carelessly makes decisions.Insulation of the group: This can promote the development of unique, inaccurate perspectives on issues the group is dealing with, which can then lead to faulty solutions to the problem.Lack of impartial leadership: Leaders control the group discussion, by planning what will be discussed, allowing only certain questions to be asked, and asking for the opinions of only certain people in the group. Closed-style leadership is when leaders announce their opinions on the issue before the group discusses the issue together. Open-style leadership is when leaders withhold their opinion until a later time in the discussion. Groups with a closed-style leader are more biased in their judgments, especially when members had a high degree of certainty.Lack of norms requiring methodological procedures.Homogeneity of members' social backgrounds and ideology.Situational context:Highly stressful external threats: High-stake decisions can create tension and anxiety; group members may cope with this stress in irrational ways. Group members may rationalize their decision by exaggerating the positive consequences and minimizing the possible negative consequences. In an attempt to minimize the stressful situation, the group decides quickly and allows little to no discussion or disagreement. Groups under high stress are more likely to make errors, lose focus of the ultimate goal, and use procedures that members know have not been effective in the past.Recent failures: These can lead to low self-esteem, resulting in agreement with the group for fear of being seen as wrong.Excessive difficulties in decision-making tasks.Time pressures: Group members are more concerned with efficiency and quick results than with quality and accuracy. Time pressures can also lead group members to overlook important information.Moral dilemmas. Although it is possible for a situation to contain all three of these factors, all three are not always present even when groupthink is occurring. Janis considered a high degree of cohesiveness to be the most important antecedent to producing groupthink, and always present when groupthink was occurring; however, he believed high cohesiveness would not always produce groupthink. A very cohesive group abides with all group norms, but whether or not groupthink arises is dependent on what the group norms are. If the group encourages individual dissent and alternative strategies to problem-solving, it is likely that groupthink will be avoided even in a highly cohesive group. This means that high cohesion will lead to groupthink only if one or both of the other antecedents is present, the situational context being slightly more likely than structural faults to produce groupthink.
