Groupthink (janis) and its prevention

Groupthink is a mode of decision-making that occurs in highly cohesive groups where the pursuit of unanimity and agreement overrides the motivation to realistically evaluate alternative courses of action. This phenomenon, identified by Irving Janis, can lead to disastrous decisions.

Definition and Enabling Conditions

Groupthink arises when the pressure for conformity and maintaining group harmony is so strong that members suppress their doubts, do not express dissenting opinions, and do not critically consider alternatives.

Conditions that favor groupthink include:

• High group cohesion: Although cohesion can be positive, extreme cohesion can lead to an excessive desire to maintain agreement.

• Group isolation: Lack of contact with outside perspectives or conflicting information.

• Directive leadership: A leader who clearly states his or her preference from the outset and discourages dissent.

• Stress and Time Pressure: High-pressure situations where a quick decision needs to be made.

• Lack of Systematic Procedures: Absence of clear methods for evaluating alternatives.

Symptoms of Groupthink

• Illusion of Invulnerability: The group feels excessively optimistic and immune to failure.

• Belief in the Inherent Morality of the Group: The group is assumed to be inherently good and its decisions are ethical.

• Collective Rationalization: Warnings or negative information are dismissed or rationalized away.

• Stereotypes about Outgroups: There is a simplistic and negative view of opponents or external groups.

• Direct pressure on dissenters: Members who express doubts are pressured to conform.

• Self-censorship: Members avoid expressing opinions that go against the apparent consensus.

• Illusion of unanimity: There is a perception of widespread agreement,often due to self-censorship and pressure on dissenters.

• Mindguards: Some members shield the group and the leader from information or perspectives that might challenge the consensus.

Strategies to Avoid Groupthink

To prevent groupthink and encourage more effective decision-making, several strategies can be implemented:

• Impartial Leadership: The leader should avoid expressing preferences at the outset and encourage open discussion.

• Encouraging Dissent: Assigning someone to the role of "devil's advocate" or creating subg
