Module 6: Social Psychology

Introduction to Social Psychology

Overview

Social psychology is the scientific study of how individuals think, feel, and behave in relation to others and their social environment. On the MCAT, this domain focuses on how people are influenced by social structures, group norms, and interpersonal interactions. Unlike sociology, which examines systems and large-scale behavior, social psychology zooms in on the individual within the social context — especially how the presence or perception of others shapes behavior.

What Is Social Psychology?

Social psychology lies at the intersection of psychology and sociology. It investigates how people:

• Interpret and evaluate social stimuli (perception)
• Are influenced by norms, expectations, and social cues (influence)
• Interact with others (behavior)

This includes everything from how we judge others’ actions (attribution) to how we conform to peer pressure, obey authority, or behave differently in groups than when alone.

MCAT Tip: Social psychology emphasizes external social factors that shape behavior — not internal traits or personality (those are covered in earlier modules).

Key Assumptions of Social Psychology

1. Behavior is situationally influenced.
   People behave differently depending on the context, even if their traits remain constant. (e.g., Someone may be quiet at school but outgoing with friends.)
2. Individuals are sensitive to social norms.
   We conform to spoken and unspoken rules in order to fit in, avoid conflict, or gain approval.
3. Perceptions matter more than objective reality.
   How someone interprets a situation often determines their response, even if their perception is inaccurate or biased.
4. Behavior is often unconscious or automatic.
   Many social responses (e.g., mimicking someone’s posture, following a crowd) occur without conscious awareness.

MCAT Tip: Questions may ask about behavioral outcomes in a given social situation. Practice applying these assumptions to passage scenarios.

Domains Within Social Psychology (MCAT-Relevant)

Domain	What It Covers	MCAT Focus
Social cognition	How people interpret and understand social cues	Attribution theory, stereotypes
Social influence	How behavior is shaped by others	Conformity, obedience, group dynamics
Interpersonal processes	Relationships between individuals	Helping behavior, aggression, altruism
Group processes	Behavior in group settings	Deindividuation, social loafing, groupthink

Interaction with Other MCAT Concepts

Social psychology links directly with:

• Sociology: Especially concepts like social roles, norms, and institutions
• Biology/Neuroscience: When discussing aggression, empathy, or mirror neurons
• Behavioral science: Through observational learning and reinforcement models
• Health disparities: Via bias, prejudice, and discrimination

Example MCAT Scenario

A student sees others running out of the building but chooses to stay seated, thinking they must have misunderstood something.

This scenario can touch on:

• Social influence (looking to others for cues)
• Bystander effect (inaction due to diffusion of responsibility)
• Attribution bias (assuming the situation isn’t serious)

Core Takeaways

• Social psychology explains how people are influenced by others and social contexts.
• It assumes that situational factors, not just personality traits, drive behavior.
• It connects deeply to perception, cognition, conformity, obedience, and group processes — all testable on the MCAT.
• Mastering social psychology allows you to analyze behavior in context, which is essential for interpreting MCAT-style passages.

Attribution Theory and Biases

Overview

Attribution theory explains how individuals infer the causes of behavior — both their own and others’. On the MCAT, this concept is highly testable and often used to probe your understanding of how people explain actions, misjudge others, and how these inferences lead to bias and error in social perception.

When we observe someone’s behavior, we instinctively ask:

Why did they do that?

The answer — whether we attribute the cause to internal traits or external circumstances — shapes our perception, emotions, and reactions.

Types of Attributions

Attribution Type	Description	Example
Dispositional (Internal)	Behavior caused by the person’s traits, values, or personality	“He’s rude because he’s a selfish person.”
Situational (External)	Behavior caused by external context or environment	“He’s rude because he’s having a bad day.”

MCAT Tip: Being able to distinguish dispositional vs. situational attributions is key to recognizing social bias questions.

Fundamental Attribution Error (FAE)

The fundamental attribution error is the tendency to overestimate dispositional factors and underestimate situational factors when explaining others’ behavior.

Example: If someone cuts you off in traffic, you might think:
“What a jerk!” (dispositional)
rather than:
“Maybe they’re rushing to the hospital.” (situational)

MCAT Tip: The FAE applies when judging others, not ourselves.

Actor–Observer Bias

The actor–observer bias highlights how we explain our own behavior differently than we explain others’.

• When we are the actor, we tend to make situational attributions. “I failed the test because the questions were unfair.”
• When we are the observer, we tend to make dispositional attributions. “He failed the test because he’s lazy.”

This bias is closely related to FAE but includes self-perception.

Self-Serving Bias

The self-serving bias is the tendency to:

• Attribute our successes to internal traits (“I’m smart”)
• Attribute our failures to external factors (“The test was too hard”)

This bias protects self-esteem and helps maintain a positive self-image.

MCAT Example: A student gets an A and says, “I’m a genius.” Gets a D and says, “My professor hates me.”

Optimism Bias and Just World Hypothesis

These two biases reflect how people perceive risk and justice in the world.

• Optimism bias: Believing bad things are less likely to happen to you than to others “Car accidents happen to other people, not me.”
• Just World Hypothesis: Believing that the world is fair — people get what they deserve “If she’s poor, she must not have worked hard.”

MCAT Pitfall: The Just World Hypothesis can lead to victim blaming, especially in questions involving inequality or prejudice.

Summary Table: Attribution Biases

Bias	Description	Who it applies to
Fundamental Attribution Error	Overemphasis on personal traits for others’ actions	Others only
Actor–Observer Bias	Others = internal; self = external explanations	Self vs. others
Self-Serving Bias	Success = me; failure = not me	Self only
Optimism Bias	Bad things won’t happen to me	Self only
Just World Hypothesis	People get what they deserve	General belief about others

Core Takeaways

• Attribution theory helps explain how we interpret causes of behavior.
• Dispositional and situational attributions lead to very different judgments of people and their actions.
• Attribution errors and biases are common, testable, and interconnected.
• Many biases serve psychological defense functions — like protecting self-esteem or maintaining worldview stability.

Social Roles, Norms, and Conformity

Overview

This section focuses on how individuals behave in response to group expectations, social rules, and perceived pressure. The MCAT frequently tests your ability to analyze behavior based on roles and norms, especially through famous psychological experiments and real-life social behavior patterns.

Humans are inherently social creatures, and much of our behavior is guided — consciously or unconsciously — by the expectations of others. These expectations shape who we are, how we act, and how we respond to social pressure.

Social Roles

A social role is a set of expected behaviors and responsibilities associated with a given status or position in society.

• Roles provide structure to interactions: doctors, parents, teachers, and students all behave according to culturally defined role expectations.
• These roles can be formal (e.g., judge, soldier) or informal (e.g., class clown, family caretaker).

Sometimes, individuals experience role conflict (when multiple roles clash, e.g., being a student and a caregiver) or role strain (difficulty fulfilling expectations within a single role).

MCAT Tip: Be able to differentiate between status (the position) and role (the behavior expected from that position).

The Stanford Prison Experiment (Zimbardo)

One of the most famous demonstrations of social role influence is Philip Zimbardo’s Stanford Prison Experiment (1971).

• Volunteers were randomly assigned to play guards or prisoners in a simulated prison.
• The guards quickly began exhibiting authoritarian and abusive behaviors.
• The experiment was terminated early due to ethical concerns and extreme role-driven behavior.

Takeaway: People can internalize roles to the point where their behavior fundamentally changes — especially in power-based or hierarchical settings.

MCAT Tip: Use this study to illustrate how social roles can override personal values.

Social Norms

Social norms are the implicit or explicit rules for acceptable behavior in a given group or society.

• Folkways: Mild norms (e.g., dressing appropriately, not interrupting)
• Mores: Norms tied to morality (e.g., being faithful in a marriage)
• Laws: Norms codified by legal systems (e.g., theft, assault)
• Taboos: Violations considered repugnant (e.g., incest, cannibalism)

Norms differ across cultures and subgroups and can evolve over time.

MCAT Tip: Norms regulate behavior without coercion — they’re learned through observation, sanction, and reinforcement.

Conformity

Conformity refers to the tendency to align thoughts, feelings, or behaviors with group norms. On the MCAT, it’s often tested through classic experiments that show how powerful social pressure can be — even when the group is wrong.

Asch Conformity Experiments (1950s)

• Participants were asked to judge line lengths in a group.
• Confederates (fake participants) intentionally gave wrong answers.
• Many participants conformed to the group’s incorrect response, despite knowing it was wrong.

Takeaway: People will conform to group norms even when it contradicts their own perception — especially when the group is unanimous.

MCAT Tip: This is an example of normative social influence — conforming to gain social approval or avoid rejection.

Types of Social Influence

Influence Type	Definition	Example
Normative	Conforming to be liked or accepted	Dressing like peers at school
Informational	Conforming because others are seen as more knowledgeable	Following a crowd in an unfamiliar airport
Compliance	Changing behavior due to a request (not authority)	Donating after a fundraising call
Obedience	Following orders from an authority figure	Administering shocks in the Milgram experiment
Internalization	Deep, lasting acceptance of a belief or behavior	Adopting a religion after group exposure

MCAT Tip: Know the difference between compliance (peer request), obedience (authority), and conformity (group norm).

Summary Table

Concept	Description	Key Example
Social role	Behavioral expectations tied to status	Student, teacher, guard
Norms	Rules for behavior	Dress codes, etiquette
Conformity	Aligning with group behavior	Asch’s line test
Normative influence	Conforming to be accepted	Laughing at a joke you don’t find funny
Informational influence	Conforming because others “must know better”	Following a group during an emergency

Core Takeaways

• Social behavior is guided by roles and norms that influence individual actions more than we often realize.
• Conformity can occur even when it goes against logic or perception — especially in unanimous groups.
• Classic experiments (Asch, Zimbardo) demonstrate the power of context, group pressure, and assigned roles in shaping behavior.
• Social influence comes in multiple forms — conformity, compliance, obedience, internalization — each with unique triggers and outcomes.

Group Dynamics and Groupthink

Overview

This section examines the psychological effects of being in a group, a topic heavily emphasized on the MCAT. Group dynamics can lead to collaboration and productivity, but they can also create dangerous pitfalls like groupthink, diffusion of responsibility, and loss of individuality. Understanding these effects is crucial for interpreting experiments, analyzing behavioral outcomes, and evaluating decision-making processes in social settings.

What Are Group Dynamics?

Group dynamics refer to the behavioral and psychological processes that occur within a group or between groups. The presence of others changes how individuals perform tasks, make decisions, and experience accountability.

Groups can:

• Enhance performance (social facilitation)
• Diminish responsibility (diffusion of responsibility)
• Impair decision-making (groupthink)
• Encourage or suppress dissent (peer pressure, polarization)

MCAT Tip: Many group processes involve shifts in accountability, responsibility, and perceived risk.

Social Facilitation

Social facilitation refers to the tendency for people to perform better on simple or well-practiced tasks when others are present — but worse on complex or unfamiliar tasks.

Originating from Robert Zajonc’s theory of arousal, the idea is that the presence of others increases physiological arousal, which helps with easy tasks but hinders difficult ones.

Task Type	Effect of Audience
Easy / well-learned	Performance improves
Difficult / unfamiliar	Performance worsens

MCAT Tip: Know that social facilitation depends on task difficulty and the performer’s skill level.

Social Loafing

Social loafing occurs when individuals exert less effort in a group than when working alone.

Example: A person in a group project contributes less because they assume others will pick up the slack.

This effect is more pronounced when:

• Individual contributions aren’t easily identifiable
• The task is uninteresting
• There’s little group cohesion or accountability

MCAT Tip: Social loafing is reduced when individual evaluation is introduced or group cohesion is high.

Deindividuation

Deindividuation is the loss of self-awareness and individual accountability in group settings, leading to increased impulsivity, risk-taking, or antisocial behavior.

Example: Rioting, looting, or cyberbullying under anonymity.

Key contributing factors:

• Anonymity
• Group size
• Arousal and crowd energy
• Diffusion of responsibility

MCAT Tip: This concept helps explain how ordinary people engage in uncharacteristic behaviors under crowd conditions.

Group Polarization

Group polarization refers to the tendency of group discussion to strengthen the dominant position or initial leaning of the group members.

• If individuals start off slightly cautious, group discussion makes them more cautious.
• If they start off slightly risky, discussion makes them riskier.

Mechanism: As group members validate each other’s viewpoints, shared opinions intensify, leading to more extreme stances.

MCAT Tip: Group polarization does not mean opinion splitting — it means opinion amplification in one direction.

Groupthink

Groupthink is a psychological phenomenon where the desire for harmony or conformity in a decision-making group leads to poor or irrational decisions.

The group suppresses dissent and fails to critically evaluate alternatives to maintain group unity.

Symptoms of groupthink:

• Illusion of invulnerability (“We can’t be wrong”)
• Suppression of dissenting opinions
• Belief in group morality
• Rationalization of poor decisions
• Pressure on dissenters to conform
• Self-censorship

Preventing groupthink:

• Encourage dissent and critical evaluation
• Assign a “devil’s advocate”
• Include outside opinions
• Allow anonymous input

MCAT Tip: Groupthink is often tested using real-world examples like policy decisions, corporate disasters, or medical teams.

Summary Table: Group Phenomena

Concept	Definition	Example
Social facilitation	Enhanced or impaired performance in presence of others	Running faster when others are watching
Social loafing	Reduced effort in group tasks	Contributing less to group homework
Deindividuation	Loss of identity in group context	Rioting or anonymous cyberbullying
Group polarization	Intensification of group’s initial opinion	Becoming more radical after a group debate
Groupthink	Poor decision-making due to conformity pressure	A company launching a product despite obvious flaws

Core Takeaways

• The presence of others can alter performance, decision-making, and self-awareness.
• Social facilitation improves or impairs task performance depending on difficulty.
• Social loafing and deindividuation reflect reduced accountability in groups.
• Group polarization strengthens shared views, while groupthink suppresses dissent and critical analysis.
• Recognizing these patterns is essential for evaluating group behavior on the MCAT.

Obedience, Compliance, and Persuasion

Overview

This section focuses on how and why people change their behavior in response to direct or indirect social pressure. The MCAT frequently tests the distinctions between obedience, compliance, and conformity, and it often references famous psychological experiments to probe your understanding of these phenomena. Additionally, this section introduces persuasion and the factors that affect how messages change attitudes and behavior.

Obedience

Obedience is a change in behavior in response to a direct command from an authority figure. Unlike conformity (influence from peers or group norms), obedience comes from an established hierarchical relationship — where someone is perceived to have legitimate power.

Milgram Obedience Experiment (1961)

• Participants were instructed to deliver increasing electric shocks to a “learner” (confederate) whenever they answered incorrectly.
• Despite visible distress from the learner (actually fake), many participants continued to obey the authority figure (the researcher) up to lethal voltages.

Key insight: People are surprisingly willing to follow authority, even when it conflicts with personal morality.

MCAT Tip: Milgram’s study highlights the power of authority in producing obedience — not personality traits.

Compliance

Compliance refers to a change in behavior in response to a direct request — but not from an authority figure. It’s often a peer, a stranger, or someone without formal power.

Technique	Description	Example
Foot-in-the-door	Start with a small request → then a larger one	“Will you sign this petition?” → “Will you donate $20?”
Door-in-the-face	Start with a large request → then scale down	“Will you donate $500?” → “Okay, $20?”
Low-ball technique	Get agreement, then increase the cost	Agreeing to a study, then being told it’s at 6 a.m.
That’s-not-all	Sweeten the deal before decision	“Order now and get two for the price of one!”

MCAT Tip: Compliance is about request-based behavior change, not belief change. People often comply without internal agreement.

Conformity vs. Compliance vs. Obedience

Type	Trigger	Authority?	Private Acceptance?
Conformity	Social/group norms	No	Sometimes
Compliance	Direct request	No	Rarely
Obedience	Command	Yes	Often reluctant

MCAT Tip: Be able to match behavioral responses to their trigger — whether it’s peer influence, authority, or persuasion.

Persuasion

Persuasion is the process of changing someone’s attitude or belief through a message. On the MCAT, it’s most closely linked to the Elaboration Likelihood Model (ELM).

Elaboration Likelihood Model (ELM)

The ELM proposes two routes to persuasion:

Route	Characteristics	When It Works
Central Route	Based on logic, content, and argument strength	When the audience is motivated and able to think deeply
Peripheral Route	Based on superficial cues (e.g., attractiveness, status)	When the audience is unmotivated or distracted

Example:

• Central: Reading a scientific article to decide which medication to take
• Peripheral: Choosing the one with the best-looking spokesperson

MCAT Tip: The central route leads to stronger, longer-lasting attitude change, but only works if the audience is motivated to engage.

Factors That Influence Persuasion

Several characteristics affect whether a persuasive message will succeed:

1. Message characteristics – Clarity, logic, and strength of the argument
2. Source characteristics – Credibility, attractiveness, trustworthiness of the speaker
3. Target/audience characteristics – Intelligence, motivation, mood, and attention level of the audience

MCAT Tip: These factors interact with the ELM — for example, highly motivated audiences care more about message content, while distracted audiences rely on superficial cues.

Summary Table

Concept	Trigger	MCAT Example
Obedience	Command from authority	Milgram shock experiment
Compliance	Direct request from peer	Donating money after a phone call
Conformity	Implicit social pressure	Asch line experiment
Persuasion (Central)	Logic + motivation	Choosing based on evidence
Persuasion (Peripheral)	Cues + distraction	Choosing based on celebrity

Core Takeaways

• Obedience involves power hierarchies; people often obey even when it goes against their values.
• Compliance is shaped by strategic request techniques — particularly foot-in-the-door and door-in-the-face.
• Persuasion can be central or peripheral, depending on how much the audience engages with the message.
• Distinguishing among conformity, compliance, and obedience is essential for analyzing social behavior on the MCAT.

Aggression, Altruism, and Helping Behavior

Overview

Human social behavior exists on a spectrum — from hostile and destructive to selfless and cooperative. This section explores the causes of aggression, the motives behind helping, and the circumstances that predict whether or not people step in to assist others. On the MCAT, these topics are framed in terms of evolutionary psychology, group dynamics, and situational cues.

Aggression

Aggression is any behavior intended to cause harm or increase dominance over another. It can be physical, verbal, or relational, and may arise from a complex mix of biological, psychological, and environmental influences.

Biological Factors

• Amygdala: Key role in fear and aggression response
• Hypothalamus: Coordinates physiological responses to threat
• Testosterone: Elevated levels are correlated with increased aggression
• Frontal cortex: Damage or underactivity impairs impulse control

MCAT Tip: Know that reduced activity in the prefrontal cortex is linked to poor aggression regulation.

Psychological and Environmental Triggers

• Frustration-aggression hypothesis: Frustration increases the likelihood of aggressive behavior.
• Learning theory: Aggression can be learned through observation (e.g., Bandura’s Bobo doll experiment).
• Social rejection, heat, and alcohol also increase aggression.

Altruism

Altruism is behavior that benefits another individual at a cost to oneself. It challenges the assumption that all behavior is selfish — and is often tested on the MCAT in the context of evolutionary biology and group survival.

Evolutionary Theories of Altruism

Theory	Description	Example
Kin selection	We help genetic relatives to preserve shared genes	Helping your sibling survive
Reciprocal altruism	Helping others increases the chance they’ll help us later	“You help me now, I help you later”
Group selection	Altruism helps the group survive, increasing individual survival	Altruistic individuals support group cohesion

MCAT Tip: Be ready to apply inclusive fitness — the idea that evolutionary success involves both direct reproduction and helping relatives reproduce.

Empathy and Prosocial Behavior

Empathy — the capacity to understand and share another person’s feelings — is a major driver of altruistic action.

• Individuals high in empathy are more likely to engage in helping behavior, even at personal cost.
• Children display empathic behavior early, suggesting it may be innate or at least strongly socialized.

Bystander Effect and Diffusion of Responsibility

Bystander Effect

The bystander effect refers to the decreased likelihood of helping when others are present. The more people who witness an emergency, the less likely any one person is to help.

Origin: The murder of Kitty Genovese in 1964, where dozens of people reportedly did not intervene.

Diffusion of Responsibility

A key cause of the bystander effect. Individuals feel less personally responsible to act when responsibility is shared across many people.

“Someone else will do something” → nobody does anything

MCAT Tip: The bystander effect is strongest in ambiguous emergencies, where people look to others to determine if action is necessary.

Factors That Increase Helping Behavior

1. Smaller groups: More personal accountability
2. Clear need for help: Unambiguous emergencies elicit faster aid
3. Personal connection: Familiarity or similarity increases empathy
4. Empathic concern: Higher trait empathy → more likely to help
5. Feeling competent: People help more when they feel they can make a difference

MCAT Tip: Helping behavior increases when people are made to feel personally responsible, capable, and emotionally connected to the victim.

Summary Table

Concept	Definition	Example
Aggression	Behavior intended to harm	Road rage, bullying
Altruism	Helping others at a personal cost	Donating anonymously
Kin selection	Helping relatives to preserve genes	Sacrificing for a sibling
Reciprocal altruism	Helping with expectation of return	Sharing food in hunter-gatherer group
Bystander effect	Less likely to help in groups	Ignoring a public medical emergency
Diffusion of responsibility	Feeling less accountable in a crowd	Not calling 911 because others are around

Core Takeaways

• Aggression is influenced by biological drives, frustration, and learned behavior.
• Altruism is often explained through evolutionary mechanisms like kin selection and reciprocal benefit.
• The bystander effect illustrates how group size reduces individual action in emergencies.
• Empathy and social connection strongly predict helping behavior.
• Know how to analyze whether someone’s action is truly altruistic or motivated by expectation of return.

Social Facilitation, Social Loafing, and Deindividuation

Overview

Group settings don’t just influence what people do — they also influence how much effort they put in, how well they perform, and how accountable they feel. This section explores three core social psychology concepts:

1. Social Facilitation – performance changes in front of others
2. Social Loafing – effort reduction in groups
3. Deindividuation – loss of self-awareness in groups

All three are classic MCAT-tested topics that appear in both standalone questions and in behavioral science passages.

Social Facilitation

Social facilitation refers to the tendency for people to perform better on simple tasks and worse on complex tasks when they are being observed by others.

Originating from Robert Zajonc’s arousal theory, this phenomenon stems from the idea that the presence of others increases physiological arousal, which helps with tasks that are well-practiced, but impairs performance on tasks requiring focus, precision, or unfamiliar skills.

Task Type	Effect of an Audience
Simple / well-rehearsed	Performance improves
Difficult / new	Performance worsens

Example: A musician may perform better in front of a crowd if the song is well-rehearsed, but worse if they’re playing a new, challenging piece.

MCAT Tip: Social facilitation depends on task complexity and the performer’s level of mastery.

Social Loafing

Social loafing is the tendency for individuals to put in less effort when working in a group compared to when working alone.

This happens because individuals:

• Feel less personally accountable
• Assume others will pick up the slack
• Perceive their contribution as less visible or necessary

Example: A student in a group project contributes less than they would on a solo assignment.

Conditions that increase loafing:

• Large group size
• Low group cohesion
• No individual evaluation

Ways to reduce loafing:

• Increase accountability (track individual performance)
• Make tasks meaningful
• Increase group cohesion

MCAT Tip: Social loafing contrasts with social facilitation — the former leads to effort reduction, the latter to arousal-driven performance changes.

Deindividuation

Deindividuation refers to the loss of self-awareness and reduced sense of personal responsibility that occurs in large groups, particularly when individuals feel anonymous or emotionally aroused.

In this state, people are more likely to engage in antisocial or impulsive behavior they normally would avoid.

Classic examples:

• Mob violence or riots
• Internet trolling under anonymous usernames
• Crowd members participating in vandalism during a protest

Key contributing factors:

• Anonymity
• Large group size
• Arousal or excitement
• Diffusion of responsibility

MCAT Tip: Deindividuation is not just anonymity — it involves a psychological shift where people feel less like individuals and more like part of a group mass.

Comparing the Three Concepts

Concept	Trigger	Effect	Example
Social Facilitation	Presence of others	Enhanced or impaired performance	Running faster at the gym when others watch
Social Loafing	Group work without accountability	Reduced individual effort	Not pulling full weight in a group project
Deindividuation	Group anonymity + arousal	Loss of self-control, increased impulsivity	Rioting, vandalism, online bullying

Core Takeaways

• Social facilitation: Presence of others boosts easy task performance but harms complex task performance.
• Social loafing: Individuals reduce effort in group settings when accountability is low.
• Deindividuation: People may act out of character when they feel anonymous and emotionally charged in a group.
• These effects all illustrate how group context modifies individual psychology — a key theme in MCAT social psychology.

Stereotypes, Prejudice, and Discrimination

Overview

This section explores how people perceive and respond to group differences, and how beliefs, emotions, and actions toward other groups can lead to bias, unfair treatment, and structural inequality. These concepts are highly relevant for understanding health disparities, physician-patient interactions, and social determinants of health on the MCAT.

We’ll distinguish between:

• Stereotypes: Cognitive beliefs
• Prejudice: Affective attitudes
• Discrimination: Behavioral actions

Stereotypes

Stereotypes are oversimplified, generalized beliefs about a group of people.

Example: “Engineers are bad communicators” or “Women are emotional”

Stereotypes can be:

• Positive (e.g., “Asians are good at math”)
• Negative (e.g., “Teenagers are irresponsible”)
• But all are reductive and potentially harmful, even if they sound flattering.

MCAT Tip: Stereotyping is a cognitive process — it does not require emotion or intention.

Stereotype Threat

Stereotype threat occurs when people feel at risk of confirming a negative stereotype about their group, leading to reduced performance.

Example: Female students perform worse on a math test when reminded of the stereotype that “women are bad at math.”

MCAT Tip: Know that stereotype threat is self-fulfilling, and that salience of identity (e.g., reminding someone of their gender or race) can trigger it.

Prejudice

Prejudice is a negative attitude or emotional response toward someone based on their membership in a particular group.

• Prejudice is affective (emotional): it involves feelings such as fear, disgust, or contempt.
• It often arises from cultural norms, learned behavior, or ingroup-outgroup dynamics.

Example: Feeling uneasy around someone of a different religion based on stereotypes, even without interaction.

MCAT Tip: Prejudice can exist without discrimination — someone may dislike a group but not act on it.

Discrimination

Discrimination is the unjust or harmful behavior toward individuals based on group membership. It’s the behavioral manifestation of prejudice.

Example: Not hiring someone because of their race or refusing to provide the same medical treatment due to perceived social class.

Discrimination can be:

• Individual: One person discriminating against another
• Institutional: Systematic policies or practices disadvantaging certain groups (e.g., housing, education, medicine)

MCAT Tip: Understand the difference between internal bias (prejudice) and external action (discrimination), especially in healthcare examples.

In-Group vs. Out-Group

• In-group: The group to which an individual belongs and identifies with
• Out-group: A group seen as different or separate

In-group bias: Tendency to favor members of one’s own group
Out-group homogeneity effect: Tendency to see members of the out-group as all the same

MCAT Tip: These mechanisms often underlie stereotyping and prejudice, even without conscious awareness.

Implicit Bias and Microaggressions

• Implicit bias: Unconscious, automatic attitudes that influence judgment
• Microaggressions: Subtle, often unintentional insults or dismissals directed at marginalized groups

Example of a microaggression: “You’re so articulate for someone from your background.”

MCAT Tip: Implicit bias may lead to discriminatory behavior even in well-meaning individuals — especially in healthcare.

Summary Table

Term	Type	Definition	Example
Stereotype	Cognitive	Oversimplified belief	“All doctors are rich”
Prejudice	Affective	Negative emotional attitude	Disliking someone for their ethnicity
Discrimination	Behavioral	Unfair treatment	Denying someone housing due to gender
Stereotype threat	Cognitive/affective	Anxiety about confirming a stereotype	Women underperforming on STEM tests
Implicit bias	Unconscious	Unaware negative beliefs	Assuming pain tolerance is higher in certain races

Core Takeaways

• Stereotypes, prejudice, and discrimination are distinct but related processes that impact cognition, emotion, and behavior.
• Stereotype threat impairs performance by activating internalized negative beliefs.
• Discrimination can be individual or institutional, and MCAT passages may explore healthcare disparities through these lenses.
• Recognize how ingroup/outgroup dynamics, implicit bias, and microaggressions contribute to social inequality — especially in medicine.

Module 6 Wrap-Up: Social Psychology

Module Summary Table

Topic	Key Concepts	High-Yield Experiments/Examples
Attribution Theory	Internal vs. external causes; bias errors	FAE, actor-observer bias, self-serving bias
Social Influence	Conformity, compliance, obedience	Asch line experiment, Milgram shock experiment
Group Dynamics	Facilitation, loafing, deindividuation, groupthink	Zimbardo prison study, brainstorming gone wrong
Persuasion	ELM: Central vs. Peripheral routes	Logic vs. celebrity endorsement
Aggression	Biological & environmental triggers	Bobo doll experiment; testosterone effects
Altruism	Empathy, kin selection, reciprocal help	Inclusive fitness; bystander effect
Stereotypes & Bias	Stereotype → prejudice → discrimination	Implicit bias, stereotype threat

Common MCAT Pitfalls

• Confusing conformity (peer/group pressure) with obedience (authority)
• Misapplying stereotype threat (only occurs when identity is made salient)
• Assuming that ingroup favoritism = outgroup hostility (not always true)
• Forgetting that social facilitation only improves easy/well-learned tasks
• Overlooking that bystander effect increases with group size and ambiguity

Tips for Test Day

• Ask: What is influencing the behavior — a peer, a group norm, or an authority figure?
• Look for classic experiments like Asch, Milgram, Zimbardo — and understand what they illustrate.
• Watch for bias language in scenarios: words like “lazy,” “emotional,” or “they all” may signal stereotyping or prejudice.
• Understand that social behaviors (helping, aggression) can be framed biologically, socially, or evolutionarily.

Module Connections

This module connects tightly to:

• Identity & Personality (Module 5) — especially when discussing self-concept, self-efficacy, and role expectations
• Culture & Norms (Module 8) — where social roles and conformity link with cultural standards
• Social Stratification & Health Disparities (Module 7) — especially when prejudice and discrimination appear in systemic form
