In-Group Biases and Group Dynamics Study Notes
In-Group Biases and Group Dynamics
Good and bad behavior are significantly influenced by how individuals identify their "tribe." People naturally identify groups they belong to—known as in-groups—and develop a distinct liking for members of those groups. This behavior is rooted in evolutionary psychology and the concept of reciprocal altruism, where individuals are altruistic toward group members because they must count on one another for survival.
The Evolutionary Basis: In an ancestral context, out-groups (those not identified as part of the tribe) were viewed as dangerous threats capable of raiding resources or engaging in war over food.
Scapegoating: This is a related term where an out-group is blamed for a problem. History contains many examples of minority groups being targeted as the cause of societal issues.
The Robbers Cave Experiment (Sherif)
Muzafer Sherif conducted a study involving boys from Oklahoma City at a summer camp. The boys were divided into two cabins: the Eagles and the Rattlers.
Culture Development: The cabins quickly developed separate cultures. The Eagles were wealthier and messier, teasing the other cabin for being "goody-two-shoes." The Rattlers took pride in a clean, tidy cabin and viewed the Eagles as mischievous and rowdy.
Hostility Escalation: Competitions like tug of war worsened the separation. Hostility escalated to the point where cabins conducted raids on each other, messing up belongings and setting fire to one group's banner.
Failed Bridge-Building: Sherif attempted several methods to repair the relationship, most of which failed:
Peace Talks: Representatives were seen as traitors and ostracized by their own cabin.
Individual Competitions: Resembled the Olympics; however, boys simply cheered for their cabin-mate, reinforcing the tribal identity.
Religious Sermons: Boys respected the speakers but interpreted "love your brother" to apply only to their own cabin.
Shared Activities: Group dinners and movie nights resulted in food fights and popcorn being thrown.
Superordinate Goals: Success was finally achieved by cutting off the water supply. The boys had to work together to restore it. This "common cause" created a bridge between the groups, a concept similar to "Tango by Green" or movies where humanity unites to fight an alien invasion.
Minimal Group Paradigm and Superficial Grouping
In-group bias can be created even through very superficial means. In one study, participants took an art survey and were supposedly separated by their artistic preferences. In reality, they were randomly assigned.
Resulting Biases: Despite the random assignment, participants created fictions that their group was more intelligent or had an appreciation for "high grail" art compared to the "low grail" art preferred by the other group.
Strength of Bias: The more shallow the reason for the grouping, the less strong the bias, but it remains present.
Social Dynamics in Schools: George Abbott School Study
Observations at the George Abbott School in Guildford, Surrey, involving nearly pupils, highlight the instinctive need to belong. Despite having similar backgrounds, colors, and uniforms, students create small differences to feel distinctive.
Identity Seeking: Around the age of , children transition from childhood to adulthood and seek security in groups like "grungers," "Garys," "indies," and "tarts."
The Loners: Even those seen as independent or "loners" often form their own group for protection and security, as being part of a group is safer than being alone and susceptible to predators.
The Stanford Prison Experiment (Zimbardo)
In August , Philip Zimbardo transformed the basement of the Stanford psychology department into a makeshift prison to study power dynamics. He recruited volunteers, paid dollars a day—approximately dollars in today's currency.
Random Allocation: Test subjects were randomly assigned to be either guards or prisoners.
Standardization of Roles:
Prisoners: Notified by actual Palo Alto police, fingerprinted, blindfolded, stripped naked, sprayed, and forced to wear dress-like garments without underwear, nylon stockings as hats, and an ankle chain. They were referred to only by numbers.
Guards: Encouraged to create rules and maintain a sense of fear. One guard, Dave Eschelman (nicknamed "John Wayne"), modeled himself after a villainous warden from the movie Cool Hand Luke.
The Breakdown: On the second day, prisoners rebelled, leading guards to use fire extinguishers and harassment (e.g., cleaning toilets with bare hands, using buckets as toilets). Prisoner , Douglas Corpy, suffered an emotional breakdown within hours, though he later claimed it was a manipulation to escape.
Conclusion: The experiment was supposed to last days but was terminated after days due to ethical concerns raised by Christina Maslak, Zimbardo’s girlfriend and an assistant professor at Berkeley. It demonstrated how quickly people adopt roles and the power of situationism.
Deindividuation and Social Influence
Deindividuation occurs when a person loses their self-identity and adopts the identity of a group. This leads to behavior that individuals would not typically perform alone.
Diffusion of Responsibility: In groups, responsibility is diffused. In a riot or the Stanford study, participants felt protected by the group level of behavior, feeling less personally responsible for brutality or property destruction.
Other Social Influences:
Reciprocity: Feeling obligated to return favors. Charities use this by giving small gifts to encourage donations.
Consistency: The desire to act in a way that matches one's self-image (e.g., being a "charitable person").
Liking: Caring about perception to avoid being seen as selfish.
Scarcity and Novelty: Things perceived as rare (stamps, coins) or unique (Heinz green ketchup) appear more valuable.
Conformity: Solomon Asch Studies
Solomon Asch researched why people conform to a group even when they know the group is wrong.
The Procedure: A participant is placed in a group of confederates and asked an easy question (e.g., matching the length of lines). The confederates all give a wrong answer before the participant speaks.
The Results:
of people conform at least once.
of people conform every single time.
The average conformity rate across studies is .
Motivations for Conformity:
Normative Social Influence: Conforming to fit in, gain social approval, and avoid feeling uncomfortable or standing out.
Informational Social Influence: Conforming because you believe the majority has valid information or expertise (e.g., choosing a well-reviewed restaurant).
Real-World Application: Juries must reach a unanimous verdict among people. The pressure to reach a consensus can lead individuals to conform to the majority view just to end the session and go home.
Obedience to Authority: Stanley Milgram
Stanley Milgram sought to understand the Holocaust by testing if Americans would follow orders to harm others. He referenced the trial of Adolf Eichmann, who claimed he was "just following orders."
Experimental Setup: A "teacher" (participant) administered shocks to a "learner" (actor) for wrong answers. Shocks started at and went up to (labeled as dangerous/lethal).
Predictions vs. Reality: Psychologists predicted only would go to the maximum voltage. In reality, of participants reached .
Factors Affecting Obedience:
Proximity: The closer the researcher, the higher the obedience.
Authority Symbols: Wearing a white lab coat increased obedience.
Prestige: Higher obedience at Yale versus a less prestigious site like Bridgeport.
Presence of Dissenters: If another participant refuses, the teacher is more likely to refuse.
Ethical Concerns: The study was highly distressing; participants believed they had killed someone. This led to the creation of ethics boards in psychology.
Modern Replications: A UK replication by Derren Brown followed the procedure exactly. Results were nearly identical, with over of participants reaching .
Group Perspectives and Individual Performance
Groupthink: Prioritizing group harmony over critical thinking. Examples include the UK government's decisions during COVID-19 and the Bush administration's pursuit of weapons of mass destruction in Iraq.
Group Polarization: An individual's opinion moves toward the extreme view of the group they are in. Myers and Bishop found that moderate students became more prejudiced or more anti-racist depending on the group they discussed topics with.
Social Facilitation:
Easy Tasks: Performance improves with an audience as arousal levels reach an optimal state.
Difficult Tasks: Performance decreases with an audience because arousal becomes overwhelming stress.
Social Loafing: Putting in less effort on a group project because responsibility is shared and individual recognition is lower.
The Bystander Effect
Individuals are less likely to help someone in an emergency if other people are present due to the diffusion of responsibility.
Kitty Genovese Case (): A woman was murdered in a New York courtyard while dozens of neighbors watched from windows but failed to call the police, assuming someone else would.
Elevator Study: People helped a researcher who dropped coins of the time when alone, but only of the time when others were present.
Intervention Strategy: To break the bystander effect, single out an individual (e.g., "You in the blue hat, call an ambulance"). This places direct responsibility on them.
Prosocial Behavior and Altruism
Definitions: Prosocial behavior is behavior intended to help others (the opposite of antisocial behavior, which violates rights). Altruism is the unselfish, selfless helping of others without seeking profit (e.g., blood donors).
Empathy: The primary motivator for altruism. It involves two components:
Cognitive Empathy: Seeing things from another's perspective.
Affective (Emotional) Empathy: Feeling what another person is feeling, such as joy for a friend's success or horror at another's pain.
