2. Groupthink may still be a hazard to your organization
The groupthink hypothesis provides us with a mode of understanding how groups perceive opportunity,
how exploitation decisions are made, how strategy paths are chosen, and what biases and distortions of reality
exist. The term groupthink was first used by Irving Janis in 1972 to refer to the phenomena of a group coming
to a consensus without critically analyzing all the various issues involved. The striving of the group for
unanimity overrides the motivation to objectively appraise alternative courses of action (Janis 1972, P. 9).
Janis (1982, P. 175) postulates that when the symptoms of groupthink are evident, decisions are likely to be
poor.
Groupthink is a very popular term used in literature carrying with it very negative connotations. The word
is usually used to describe decisions and their resulting disasters1. Groupthink is a widely studied phenomenon
and has been used to explain many historical political decisions and their resulting consequences2. This
metaphor can lead to a better understanding how groups make their decisions, what information they used and
didn’t use, what were their underlying group assumptions and what other influential factors were involved.
The groupthink phenomenon arises where individual inclinations to be critical and independently analyze
issues are sacrificed in the interests of maintaining harmony within the group so a state of cohesion can occur.
This results in people providing only opinions that they believe fall into the gambit of acceptable thinking.
Members sub-consciously want to be part of the group and fear embarrassment, appearing outspoken and
stubborn or disruptive to the flow of the group. This is likely to be based on a feeling of low self-efficacy
(Baron 2005), and results in a consensus at the cost of rationality, with potentially faulty premises and failure
to look at important pieces of information and potential consequences. As any doubts are suppressed, each
member of the group believes that the decision made had full support of all the members.
According to the hypothesis, groupthink is most likely to occur when a group is very cohesive, insulated
with lack of impartial leadership, lack procedure methodology, and have a homogeneous social background
and ideology (Janis 1972). The groupthink process is actually triggered by some form of an external crisis,
event or failure which induces stress and feelings of low self efficacy on the group, challenging their existing
decision making processes and sometimes creating moral dilemmas.
Janis (1972) postulated that the symptoms of groupthink are;
The illusion of invulnerability which creates over optimism of potential success and willingness to take
high risks,
An inherent belief of their own morality where the consequences of their decisions are ignored,
Collective rationalization where warnings, signs and messages are rationalized according to existing group
assumptions,
Negatively generalized and stereotyped views of external people and entities, where they view others as
weak and foolish,
Self censorship and pressure on dissenters to carry the group line and not express any disagreements,
including the suppression of outside views disagreeing with the group,
The illusion of unanimity in the belief that individual views conform to the majority view and silence
means consent,
Social pressure on those who have doubts about group consensus, and
1 The ‘groupthink’ phenomenon only exists if the symptomatic conditions are present. ‘Groupthink’ decisions may not necessary result
in a poor decision and failure. There are many other reasons besides groupthink that can lead to a poor decision and failure, for
example; the lack of necessary information, poor judgment, lack of experience of the issues, luck, unexpected actions by
competitors, government, and suppliers, etc., group competence, the heuristics used (discussed later in this chapter), and inadequate
time for proper decision making.
2 Janis (1972) first used the concept to appraise the Korean War stalemate and Vietnam War escalation. In 1982, Janis examined the
Watergate cover-up. Kramer (1998) examined the Bay of Pigs and Vietnam decisions, with additional evidence casting some doubt
on Janis’s analytical conclusions. Hart (1994) and Whyte (1998) enhanced the groupthink hypothesis. Smith (1984) analyzed the
US rescue mission to Iran in 1979. Vaughan (1996) and Schwartz and Wald (2003) looked at the way NASA operated in relation to
the Challenger and Columbia disasters.
3. There are self appointed ‘mind-guards’ to protect the leader and group from information that may threaten
any potential group cohesiveness.
Kowert (2002) also added that an overload of information may also contribute to causing the groupthink
phenomena.
The result of this is a defective decision making process characterized by;
The decision had an incomplete consideration of possible alternative courses of action, 2. The problem will
have clearly specified objectives, 3. There was a failure to properly analyze risks of the preferred choice, 4.
There was a failure to reassess earlier discarded options, 5. There was a poor information search, 6. There
was bias in the selection and processing of information, and 7. No contingencies were conceived.
The result of this process is a decision that has a very low probability of a successful outcome. A diagram
of the groupthink process is shown in Figure 1.
The effect of groupthink is to strengthen group cohesion at the cost of increasing the influence of group
bias and lowering of the quality of decisions. The groupthink hypothesis doesn’t say that all decisions will be
poor ones, only that there is a high probability that they will be poor. The hypothesis just shows one way that
groups can get trapped within their own insular thinking and decision making process. It shows where groups
are vulnerable, especially cohesive and harmonious groups which can very easily create their own information
filters and allow biases to influence them.
When a group of people such as managers share a similar background, then there is danger of the
groupthink phenomena occurring. This may be the case in many businesses and particularly of the Chinese
SMEs in South-East Asia. This situation can impair the ability of the company to grow and change into new
trajectories. Diversity of thinking in strategy is needed in environments that change quickly because of
changing consumer demand, technologies, and intense competition (Hambrick 1995).

The important lesson from the groupthink hypothesis is to understand the steps that can be taken to avoid
this phenomenon. There are many methods that can assist groups avoid biases and selected patterning4. After
the Bay of Pigs fiasco, the then US President John F. Kennedy took steps to avoid the groupthink phenomenon
happening again. He used outside expertise and promoted the thorough questioning of different viewpoints,
both within the closed group and outside the group in departmental sub-groups. John F. Kennedy was also
deliberately absent at some meetings to allow a freer flow of opinions and prevent group bias towards his own
thinking (Janis 1972 pp. 148-149).
Group problem solving can be very useful, particularly when a group is socially diverse and ‘cognitive
diversity’ can exist and operate. A diverse and functioning group can greatly enhance the problem solving
because greater knowledge is available, more ideas can be generated with better evaluation, an improved
ability to find errors and a wider diversity of experience. Under the right circumstances, group thinking has
much superior capabilities than individual thinking (Klein 1999, P. 245).

4 Janis (1982) suggested that a number of processes be included in group processes to eliminate the pitfalls of groupthink and develop
more impartiality. These steps include; assigning each member of the group the role of a critical evaluator, higher people should
abstain from expressing opinions when assigning tasks to the group, several independent groups should be set up to bring in more
ideas and points of view, all alternatives should be examined, each member should discuss the issues with trusted people outside the
group, invite outside experts to give their opinions, and a group member be assigned the role of ‘Devil’s advocate’.
