Groupthink
What is groupthink?
• groupthink occurs when
a group makes faulty
decisions because
group pressures lead to
a deterioration of
“mental efficiency,
reality testing, and
moral judgment” (Irving
Janis, 1972, p. 9).
Why should we care about
groupthink?

Symptoms of Groupthink
•
•
•
•
•
•
•
•
Illusion of invulnerability
Collective rationalization
Belief in inherent morality
Stereotyped views of out-groups
Direct pressure on dissenters
Self-censorship
Illusion of unanimity
Self-appointed ‘mindguards’
Illusion of Invulnerability
• Creates excessive
optimism that
encourages taking
extreme risks.
Collective Rationalization
Belief in Inherent Morality
• Members believe
in the rightness
of their cause
and therefore
ignore the ethical
or moral
consequences of
their decisions.
Stereotyped Views of
Out-groups
Direct Pressure on Dissenters
• Members are under
pressure not to
express arguments
against any of the
group’s views.
Self-censorship
Illusion of Unanimity
The majority view
and judgments
are assumed to
be unanimous.
Self-appointed ‘mindguards’
Remedies for Groupthink
• The leader should assign the role of critical
evaluator to each member
• The leader should avoid stating preferences
and expectations at the outset
• Each member of the group should routinely
discuss the groups' deliberations with a
trusted associate and report back to the
group on the associate's reactions
More Remedies for Groupthink
• One or more experts should be invited to
each meeting on a staggered basis and
encouraged to challenge views of the
members.
• At least one member should be given the role
of devil's advocate (to question assumptions
and plans)
• The leader should make sure that a sizeable
block of time is set aside to survey warning
signals.
Dealing with Dissenters
• pressure not to
express arguments
against any of the
administration’s
actions.
Imminent Danger from
Weapons of Mass Destruction
Limited Examination of Risks
of Actions
• failure to work out
contingency plans
Self-appointed ‘mindguards’?
Janis’ Antecedent Conditions
• very strong group cohesion was the primary
antecedent condition for group think
– normative and informational social influence
should both be very powerful forces.
• complemented by
– group antecedent conditions
– situational antecedent conditions
Group Antecedent Conditions
• the insulation of the group from outside
influences
• the lack of a tradition of impartial
leadership (i.e., directive leadership)
• lack of group norms favoring methodical
search procedures
• homogeneity of member attitude or
ideology
Situational Antecedent
Conditions
• high stress from an external threat,
• group insulation from critics
• low situational member self esteem
– due to recent failure
– de to complexity of the current decision
problem
Symptoms of Groupthink
• overestimation of the in-group (as strong, smart,
invulnerable, morally superior)
• corresponding negative stereotyping regarding the
outgroup (as weak, immoral, vulnerable, stupid,
and wrong)
• close-mindedness (e.g. rationalization of doubt)
• pressures for uniformity (via mindguards, self
censorship, illusion of unanimity)
Defective Decision-making
Processes
• inadequate contingency plans for failure
• inadequate information search, biased assessment
of risks, costs, benefits and moral implications
(e.g. inadequate consideration of worst case
scenarios),
• incomplete consideration of the full range of
decision options
• failure to reconsider the extent to which
original/fundamental objectives were served by
the advocated action.
Limitations
• Experimental failure to verify Janis'
antecedents
Baron's Ubiquity Model of
Groupthink
• social identification with the collection of
individuals they are among.
– linked by some common purpose, history,
shared fate, or emotional orientation
– Common allegiance and social identity
• self-definition, and self esteem are strongly affected
by one’s social allegiances
– In-group members share their vested interests,
values, limitations and frames of reference.
Ubiquity Model
• Social identification
– deviance may threaten one’s self categorization
as an in-group member
– use of
• cognitive distortion
• semantic reinterpretation in an effort to minimize
perceptions of social deviance and will
– show drops in self esteem when such cognitive
avoidance is difficult.
Ubiquity Model
• First antecedent
– Social identification
• Second antecedent
– Group interaction and discussion must produce or
reveal an emerging or dominant group norm
• Third antecedent
– low situational self efficacy in which group members
generally lack confidence in their ability to reach
satisfactory resolution of the conundrum facing them
Affect Control Theory
• Institutions are created to reinforce
significant social identities based upon
fundamental shared affective orientations
Fundamental Emotions
Optimism/Pessimism
Economics
Anger/Contentment
Politics
Agreeableness/Disgust
Religion
What can we do about it?
Knowledge is Power
Think About Underlying
Assumptions and Implications
Challenge Others to Think
Philosophy
• Critical Philosophy
– Death and ostracism as the punishment for
disagreement with the group mind
• Dogmatic Philosophy
– Reinforces the existing order
The Crisis of Our Time
• Our time is similar to the times of Plato
– The end of the Classical period
– The end of the Athenian Empire
• End of a major cycle
– The end of a 200-year philosophy of
competitive individualism
– The end of the American Empire
