Groupthink vs. Group Polarization: What's the Difference?

By Janet White || Published on November 22, 2023
Groupthink is the practice of thinking or making decisions as a group, often leading to unchallenged, poor-quality decisions. Group polarization refers to the tendency of a group to develop more extreme positions over time.

Key Differences

Groupthink occurs when a group prioritizes harmony and consensus over critical evaluation, often resulting in irrational or dysfunctional decision-making. Group polarization, however, involves the tendency of group members to shift towards more extreme positions than they initially held, following group discussions.
In groupthink, the desire for unanimity suppresses dissent and leads to a deterioration in mental efficiency, reality testing, and moral judgment. In group polarization, existing views become more extreme due to the influence of the group consensus, which can enhance or suppress certain viewpoints.
Groupthink is driven by the desire to maintain group cohesion and avoid conflict, often at the expense of sound decision-making. Group polarization is driven by factors like a desire for social comparison, persuasion from others, and exposure to similar viewpoints.
Groupthink can lead to flawed decisions in businesses or governments due to the suppression of dissenting opinions. Group polarization is often seen in political or social groups, where discussions reinforce a prevailing social or political attitude, pushing the group to more extreme stances.
To prevent groupthink, encouraging open dialogue and dissent is crucial. For managing group polarization, exposure to diverse viewpoints and structured debate can help in balancing extreme views.
