8Why do groups fail...?(or, when 2 2 3)
- Ineffective leadership skills
- Lack of rigorous methods
- Wrong group structure
- Group member homogeneity
9Factors affecting group judgment
- Input variables
- Conformity
- Polarization
10Input variables affecting group processes
- Task norms.
- Process norms.
- Group size.
- Group communication patterns.
- Perceived member status.
- Individual personality characteristics.
- Group experience.
11Conformity
- Tendency for individual responses to conform more
closely to those of the group after exposure to
the groups opinion. - Factors affecting strength of the effect.
- Response uncertainty.
- Concern for self image.
- To avoid possible censure.
- Classic example - Groupthink.
12Conformity and consensus
- When consensus is the goal, there is additional
stimulus to assent to the groups position even
though one may personally disagree with it. - Groups decision rule.
- Factors affecting weight given to individuals
opinions... - Quality of resulting consensus...
13Conformity (likhet, ensrettethet)
- Definition
- A change in a persons behavior or opinions as a
result of real or imagined pressure from a person
or a group of people. - Dilemma of being a social animal
- Resultant tension between
- Values associated with Individuality.
- Values associated with Conformity.
The Establishment tends to like Conformists
better than Non-conformists.
14Conformity
- Variables that affect conformity behavior
- Whether the majority opinion unanimous or not.
- Kind of person the individual is (low in
self-esteem, for example). - Who is in the reference group.
- Group influence increases if
- It is composed of experts.
- The members are important to the individual.
- The members are comparable to the individual
15Group cohesivenessCauses and consequences
16Conformity in extremis Groupthink
17Groupthink in actionThe National Security
Council and the Bay of Pigs - 1961
- NSC assumption
- No one will know that the US is involved. CIA
cover story will be believed. - Cuban AF is ineffective and can be destroyed by
early attack using two B-26 bombers. - 1400-man force has high morale and will be a
superb force. - Castros army is very weak. The brigade will be
able to establish a beachhead. - Brigade landing will spark sabotage throughout
Cuba and lead to Castros overthrow. - If the landing fails, the brigade can escape to
the mountains and reinforce the guerillas.
- Available counter-evidence
- Stories appear in newspapers about CIA training
people in Central America. TV also reports this. - B-26s were obsolete, required frequent
maintenance, could not complete bombing runs.
British intelligence reports that Cuban AF is
very effective. - High initial morale due to CIA lies of US
support. NSC members knew of a mutiny attempt in
Guatemala morale was very low. - State Dept. knew the army was very efficient and
could get to the beachhead rapidly (within 24
hours the brigade was surrounded by 22,000 men). - CIA had no firm intelligence about any
underground of any size in Cuba. A British paper
had surveyed Cuba and found all-time high support
for Castro only 4 months earlier. - No one was aware of guerilla forces in the
mountains. Brigade was trained in brigade tactics
not guerilla warfare. 120km of swamp and dense
forest between the Bay and the mountains.
18Prescriptions for overcoming Groupthink
- Set high priority to voicing objections and
concerns in the meeting. - Leader should not state preferences in problem
diagnosis or solution alternatives. - Break into subgroups, working on the same
problem, same goal. - Seek external council, outside the group, subject
to confidentiality concerns. - Periodically bring in outside experts to
challenge current thinking. - On a rotating basis, use a Devils Advocate to
challenge current thinking, pick at weak points. - Construct alternate views, scenarios, goals,
world views. - Institute a second chance meeting after a
conclusion has been reached.
19Polarization
- Reported tendency for average group members
responses to shift further in the direction of
the groups initially dominant tendency after
interaction and discussion. - Associated primarily with attitudes and
preferences. - Processes leading to polarization...
- Information effect.
- Predominant influence of argument and facts.
- Active espousal of a position.
20Dysfunctional group behaviors
- Anchoring Effect
- Inequality of Participation
- Causes...
- Deference to seniors
- Have less to offer
- Less data
- Wrong group structure
21Self-justification (selvberettigelse)
- Definition
- Actions taken by people to justify or explain
their behaviors to convince themselves (and
others) that the selected action was logical and
reasonable. - Basic process Cognitive Dissonance
- A state of tension that occurs when an individual
simultaneously holds two cognitions (ideas,
attitudes, beliefs, opinions) that are
psychologically inconsistent. - An unpleasant experience that people try to
reduce.
22Self justification an example Washington Post
News Service, November, 1971
23Theory of cognitive dissonance
- Man is not a rational animal.
- Man as a rationalizing animal.
- People are not motivated so much to be right
rather, he/she is motivated to believe that he or
she is right (wise, decent, good)
Its better to look good than to be good
Fernando Lamas
24Aspects of dissonance
- As a consequence of making a decision
- Importance of irrevocability
- Immoral behavior
- Justification of effort
- Dissonance theory predicts that if a person works
hard to achieve a goal, that goal will be more
attractive to him than for someone who achieves
the same goal with little or no effort. - Justification of cruelty
- Why do good people inflict pain on others?
- And how do they deal with it?
25Dissonance reduction and rational behavior
- Dissonance reducing behavior
- Negative consequences
- Maladaptive, keeps us from learning important
facts or finding real solutions - Positive consequences
- Ego defensive behavior, maintains positive self
image. - Results from the lab
- People do not remember in rational-functional
manner. - Remember plausible arguments for personal
position - Remember implausible arguments in agreement with
opposing position. - Selective Perception
26Prejudice (fordom)
- Definition
- A hostile or negative attitude toward a
distinguishable group based on generalizations
derived from faulty or incomplete information. - Closely related to stereotyping.
- An over-generalization attribution of identical
characteristics to any person in a group,
regardless of actual variation within the group
members. - Done all the time, can have either positive or
negative connotations. - Characteristics
- Most stereotypes are not based on valid
experiences. - Hearsay or images from the media are influential.
- Oten the stereotypes are constructed from pure
fantasy to justify prejudices and cruelties.
27Causes of prejudice
- Economic and political competition.
- Given limited resources, the dominant group might
try to exploit a minority group in order to gain
a material advantage. - Prejudice tends to increase in difficult times.
- Displaced aggression.
- Scapegoating.
- Focusing aggression on visible and relatively
powerless groups that are disliked to begin with.
- Examples?
28Causes of prejudice (continued)
- Personality needs.
- Some research has shown that there are certain
personality types that are predisposed to being
prejudiced, not because of external factors. - Implications for management?
- Conformity to existing social norms.
- Pressure to conform can be very strong.
- Examples?
29Responses to social influence
- Compliance (imøtekommelighet)
- Mode of behavior of a person who is motivated to
gain rewards or avoid punishment. - Lasts as long as reward/punishment exists.
- Identification
- Response brought about by individuals desire to
be like the influencer. - Internalization
- Most permanent, deeply rooted response to social
influence reward for the belief is intrinsic. - The behavior becomes independent of the source
and can be hard to change.
30Coordinating mechanisms
- Specific actions
- Expected results
- Informal focus on decision processes
- Formal, intermittent focus on decision processes
- Formal, continuous focus on decision processes
Rules, policies and procedures
Goal-setting and planning processes
Direct contact and committees
Task forces and temporary teams
Permanent teams and departments
31Types of coordination
- Cognitive coordination
- The degree to which team members share compatible
conceptual structures with respect to the factors
that influence the outcomes of their decisions. - Semantic coordination
- Refers to the adequacy and efficiency of the
language used by team members to communicate
information. - Epistemic coordination
- Refers to the knowledge aspects of the team
problem. The need to know and ability to
know.
32Group processes
- Interacting group
- Nominal group technique
- Delphi group
33Interacting group characteristics
- Most common group structure.
- Problem statement by the group leader.
- Unstructured discussion.
- Consequences for problem solving...
34Interactive group Disadvantages
- Lack of structure.
- High variability in leaders and members.
- Effort used to maintain socio-emotional
relationships. - Generalization leads to low quality.
- Reactive search behavior, short focus, task
avoidance, tangential discussions. - Dominant individuals control the agenda.
- Group norms emphasize conforming behavior.
- Tendency to conclude without a sense of closure.
35The Nominal Group technique
36Nominal group Advantages
- Consistency in decision making.
- Balanced concern for socio-emotional and task
instrumental roles. - Opportunity to think and write ideas increases
tendency for focused ideas of higher quality. - Tolerance for off the wall ideas.
- Structure forces equality of participation.
- Higher sense of closure, greater feeling of
satisfaction, greater willingness to work towards
implementation.
37The Delphi technique
38The Delphi method Characteristics
- Physically dispersed.
- Systematic collection and combination of
information. - Consensus achieved through feedback.
39The Delphi method
Disadvantages
Advantages
- Isolated generation of ideas.
- Problem complexity addressed in the process.
- Proactive search behavior.
- Anonymity and isolation.
- Lack of socio-emotional satisfaction.
- Possible communication and interpretation
problems. - Conflicting and incompatible ideas are resolved
by pooling. - No face-to-face problem solving to resolve
conflicts.

- Role orientations
- Relative quantity of ideas
- Search behavior
- Nominal behavior
- Equality of participation

51Experimentation in social psychology
- Challenges
- Control versus Impact
- Realism
- Experimental realism experiment has an impact
on the respondent and forces a serious approach - Mundane realism how similar the laboratory
setup is to the outside world - Deception
- Often needed to achieve experimental realism
- Requires disguising the true purpose of the study
52Experimentation in social psychology
- Challenges (continued)
- Ethical problems
- Unethical to tell lies to people
- Telling lies can lead to invasion of privacy
- Experimental procedures can entail unpleasant
experiences - Do the Ends justify the Means?
- Post-experimental session
- Used to un-do discomforts and deceptions
- Turn the experiment into an educational
experience for the respondent
53Something to think about
- Morality of finding out unpleasant things
- What is the moral responsibility of the
researcher for what is discovered? - Example
- Use of Nazi medical data by researchers.
- Potentially very useful, but
- Social scientists are frequently confronted with
value judgments like this in their work. - Again
Do the Ends justify the Means?
