Group Dynamics, Groupthink, and Social Prejudice Study Notes

Group Polarization and Social Influence

• Group polarization is defined as the enhancement of a group's prevailing attitudes.
• When a group discusses a particular topic, the discussion serves to strengthen an attitude that is already shared by the group members.
• This phenomenon can lead to negative outcomes if the group is leaning toward an incorrect or dangerous direction.
• There are two primary theories explaining group polarization:
      - Informational Influence: This is an influence that results from accepting evidence about reality.
      - Normative Influence: This is an influence based on a person's desire to be accepted or admired by others.

Illustrations of Group Norms: Mean Girls and Girl World

• The transcript utilizes a clip from the film Mean Girls to illustrate the strict rules and social codes within a specific group known as "The Plastics."
• Characteristics of "Girl World" include:
      - Regulations on clothing: You cannot wear a tank top two days in a row.
      - Hair styling rules: You can only wear your hair in a ponytail once a week.
      - Specific attire days: Members can only wear jeans or track pants on Fridays.
      - Social consequences: Breaking these rules results in being unable to sit with the group at lunch.
      - Group consideration: Members must look before asking someone to eat lunch with them to be considerate of the rest of the group.
      - Peer approval: Decisions such as buying a skirt or liking a specific guy require the approval of friends to ensure the choice is "good."

Groupthink: Origins and Definition

• Groupthink is the process of making unrealistic decisions after suppressing unwelcome information.
• Psychologist Irving Janis developed the concept of groupthink after analyzing decision-making procedures behind several major historical disasters.
• Irving Janis believed these errors were caused by the tendency of decision-making groups to suppress dissent in the interest of maintaining group harmony.
• Significant historical examples of groupthink include:
      - Pearl Harbor.
      - The Bay of Pigs invasion.
      - The Vietnam War.
      - The Challenger space shuttle disaster.
• A cohesive group is defined as one whose members feel positive toward the group and are strongly motivated to retain their membership. This cohesiveness leads to a "concurrent seeking tendency" that is the core of groupthink.
• Factors predisposing groupthink include:
      - A highly insulated group with restricted access to outside ideas.
      - A stressful decision-making context caused by budgetary restraints or external pressure.
      - A history of recent setbacks.

Historical Case Study: The Bay of Pigs Invasion ($1961$)

• In $1961$, the United States attempted to invade Cuba to overthrow Fidel Castro.
• The CIA and military leaders planned to use Cuban exiles for the invasion.
• President Kennedy approved the plan after consulting top advisors, despite potential flaws.
• Castro was notified of the threat, and the U.S. ultimately decided not to provide the expected help to the exiles.
• The exiles lacked air support and ammunition, leading to a disastrous outcome.
• CIA agents later blamed Kennedy for not authorizing the necessary assistance.

Detailed Case Study: The Space Shuttle Challenger Disaster ($1986$)

• Context and Pressure: NASA was under public and political scrutiny because they promised to launch many shuttles per year and were falling behind. There was pressure to launch so President Ronald Reagan could mention the mission in his State of the Union address.
• Mission Specifics: The launch took place in January $1986$. It featured the first non-astronaut, a teacher named Christa McAuliffe.
• Technical Engineering Conflict:
      - Engineers from Morton Thiokol warned against the launch because the temperature was approximately $29$ degrees Fahrenheit.
      - The engineers recommended not launching until the temperature reached at least $53$ degrees Fahrenheit.
      - The concern was the O-ring—the seal between sections of the rocket boosters. In cold temperatures, O-rings lose elasticity, warp, and fracture, preventing a proper seal.
      - Despite previous evidence of O-ring problems in cold weather, NASA management and Morton Thiokol executives overruled the engineers.
• The Launch: The shuttle exploded roughly one minute after liftoff. Schoolchildren across the country were watching the event live.
• Investigation: A task force appointed by President Reagan concluded that NASA was in the wrong and the accident was preventable.

The Eight Symptoms of Groupthink

1. Illusion of Invulnerability: Excessive optimism that blinds members to warnings of danger. This leads to increased risk-taking.
2. Unquestioned Belief in the Group’s Morality: Members ignore possible moral problems and fail to consider the consequences of individual or group actions.
3. Rationalization: The group discounts challenges by collectively justifying their decisions. This prevents members from reconsidering their beliefs and causes them to ignore warning signs.
4. Stereotyped View of Opponent: In-group members ignore or demonize out-group members who challenge their ideas, dismissing them as too weak or unintelligent to counter the group.
5. Conformity Pressure: Group members rebuff or ignore those who raise doubts about the group's assumptions and plans. Those who question the group are often seen as disloyal.
6. Self-Censorship: To avoid uncomfortable disagreements, members withhold or discount their own misgivings. They keep "their mouths shut" even if they believe a mistake is being made.
7. Illusion of Unanimity: The belief that everyone in the group is in agreement and feels the same way. This makes it difficult for individuals to speak out.
8. Mind Guards: Some members protect the group from information that would call into question the effectiveness or morality of its decisions. This involves actively hiding or preventing the sharing of problematic information.

Chapter 12: Stereotypes, Prejudice, and Discrimination

• Prejudice: A preconceived negative judgment of a group and its individual members. While usually negative, it can occasionally be positive.
• The ABCs of Attitudes regarding Prejudice:
      - Affect (Feelings): Disliking those who are different.
      - Behavior (Inclination to act): Acting in a discriminatory manner.
      - Cognition (Beliefs): Believing others are ignorant or dangerous.
• Stereotype: A set of beliefs (positive or negative) about the characteristics or attributes of a group. This often results in rigid and over-generalized imagery.
• Impact of Stereotypes: Stereotypes can influence the amount individuals are paid, the careers they follow, and their overall experiences at work.
• Stereotype Threat: A phenomenon where individuals fear they may confirm negative stereotypes about their social group.
      - Example: When women are reminded of the negative (and untrue) stereotype that women are poor at math, they perform more poorly on mathematical examinations than if they are not reminded.

Questions & Discussion

Discussion on Tortoise Biology and Care

• Speaker 1: Mentions obtaining a new "baby" (likely a pet) arriving on Friday.
• Speaker 2: Discusses the physical characteristics of their pet, noting it has "flippers" and doesn't have "little toes."
• General Information:
      - The Russian tortoise is strictly an herbivore.
      - While they could have a worm as a "special treat," they shouldn't usually eat them because they are herbivores, unlike other tortoises which are omnivores.
      - Lizards require care regarding their shedding process.

Dialogue on Groupthink (Dramatization of Challenger Meeting)

• Engineer (Roger): "Our recommendation is… not launching until the temperature is at least $53$ degrees."
• NASA Management: "At that rate, it could be spring before the shuttle would fly… When do you want me to launch, next April?"
• Engineer (Roger): "Launching it below freezing is an act away from goodness… we can expect increased erosion and blow-by."
• NASA/Management (Larry Malloy): "I'm appalled that they could arrive at the recommendation not to launch given the data that’s been presented."
• Executive (Joe Kilminster): Initially recommends no launch, but after a private caucus, changes the recommendation to "proceed with the launch."

Dialogue on Religious Display

• Christianity Clip: A character displays a "rule book," "ethics manual," "morality player," and a "King James version" Bible in a leather bag.
• Character A: "So what do you wear to display your Christianity?"
• Character B: "Well, nothing, I guess… I just try to follow Christ in the way I live my life. I don't feel like I have to wear my heart on my sleeve."
