Title: Carter Racing
1Carter Racing
- In the next 20 minutes
- Read the case carefully and make a race/not race
decision - Use any extra time to develop the logic of your
decision - No talking please
2Carter Racing(2)
- As a group, agree on your roles
- i.e., 1 Pat Carter, 2 Paul Edwards, 2 Tom Burns
- Take 25 minutes to reach a group consensus about
racing or not racing - You will have 60 seconds to justify your decision
to the class
3Decision Choices
- Race
- Top Five 50
- Out of Money 12
- Blow Engine 29

9What does the case demonstrate?
- Managers face problems when making decisions
under uncertainty - Decisions that occur in a behavioural context are
often ambiguous critical pieces of information
are either unavailable or are suppressed - Whos opinion should you believe?
- Importance of gathering all relevant data
- Perceptions bias the use of information
- Quantitative calculations are only as solid as
the data that are used in making them GIGO
10Decision Biases
- Overconfidence - High Efficacy
- affects risk perceptions
- Minimize the importance of evidence that is
counter to our perspective - Majority of Ind. Racers almost always Race
- Escalation of commitment
11What are Framing Effects?
- Framing refers to the manner in which objectively
equivalent alternatives are presented - You have blown engines in 7 of 24 races this
season, a rate of 29. If you blow an engine in
this race you lose all your support for next
year, including the 500,000 oil and 300,000
tire sponsorship - You have finished in the top 5 and won prize
money in 12 of 15 races you finished this season,
a rate of 80. If you finish in the money in
this race you will secure both the 500,000 oil
and 300,000 tire sponsorships.
12Space Shuttle Challenger
- NASA operating under severe budget pressures
- Launch was a media event to attract attention
- 24 previous successes
- Shuttle had been reclassified from
developmental to operational (i.e., safe) - Groupthink at NASA - is Morton-Thiokol with or
against us? - Morton-Thiokol concerned about future booster
contracts - concern gave NASA what they wanted
13Group-level Effects
- Risk Taking
- groups tend to make more extreme decisions that
individuals (called group polarization) - Information Pooling
- groups tend to focus on information shared by all
members and ignore information held by a few.
14Vigilant Decision-making(a model for making
crucial decisions)
- 1) Identify a wide range of objectives to be
achieved by the decision - 2) Generate a comprehensive list of alternative
courses of action - 3) Search for new information relevant to
evaluate the alternatives - 4) Process all information in ways that minimize
biases - 5) Reconsider pros cons of rejected
alternatives - 6) Carefully examine the costs, benefits, and
risks that flow from the preferred alternative - 7) Develop implementation plan, with special
attention given to contingency plans
15Groupthink
1) Illusion of invulnerability
2) Construct rationalizations
3) Morality of position is unquestioned
4) Stereotypes--distort image of other parties
5) Pressure applied to those who express doubts
about the groups position
6) Self-censorship--deviations from consensus are
avoided
7) Illusion of unanimity
8) Mindguards--leaders and fellow members
protected from adverse information
16Groupthink
17Warning Signs of Groupthink
- Teams isolating themselves from external sources
of information through mindguards - Feeling under pressure
- Exhibiting defensiveness - e.g., stereotyping
others -
- Feeling they are doing what is moral or right
- Minimizing the public expression of doubt
- Having strong leaders that intentionally or
unintentionally discourage input and real debate - Creating the illusion of unanimity by
self-censorship - Creating the illusion of invulnerability
18The Groupthink Process
- Characteristics of Groupthink
- Illusion of invulnerability
- Collective rationalization
- Belief in the inherent morality of the team
- Stereotypes of other groups
- Self-censorship
- Illusion of unanimity
- Self-appointed mind guards
- Groupthink Leads to Defective Decision Making in
Terms of - Incomplete survey of alternatives
- Incomplete survey of goals
- Failure to examine risks of preferred choice
- Selective bias in processing information at hand
- Failure to reappraise alternatives
- Failure to work out contingency plans
- Initial Conditions
- High Cohesiveness
- Insulation of team from outsiders
- Lack of methodical procedures for search
appraisal - Directive leadership
- High stress with low hope for finding a better
solution than one favoured by the leader or other
influential person - Complex/changing environment
Conformity- Seeking Tendency of Group
19Remedies to Groupthink
- Assign encourage the role of critical evaluator
in each group member - Leaders should avoid stating preferences adopt
an impartial stance - Use multiple groups to work on the same questions
- Protect security, but seek outside counsel
insight - Invite outside experts have experts challenge
the views of core members
20Conformity
21Remedies to Groupthink (cont.)
- When discussing alternatives, at least 1 person
should be assigned the devils advocate role,
to fully evaluate options - Take time to address how enemies may respond -
develop scenarios - When evaluating policy alternatives, break up
into small groups then reform to sort through
differences - After reaching a preliminary consensus, group
should hold a second-guess meeting - 10 The behaviour of the leader is key
