Assumptions of Groupthink

  1. Cohesiveness: High cohesion leads to a reliance on group values and attitudes, influencing decisions.

  2. Unified Problem Solving: Groups seek harmony, leading to neglect of critical assessment.

  3. Complex Decision Making: Groups face challenges understanding available alternatives and dynamics.

Antecedent Conditions for Groupthink

  1. Group Cohesiveness:

    • Beneficial for group dynamics but may exert pressure for conformity.

  2. Structural Factors:

    • Illusion of unanimity, mindguards, and pressure on dissenters.

Consequences of Symptoms

  • Potential Flawed Decisions:

    • Emerge due to the combination of antecedent conditions and symptoms of groupthink, decreasing the likelihood of effective problem-solving.

Final Thoughts
