Discrimination

Discrimination is an MCAT favorite because it sits at the intersection of individual psychology and social structure. Understanding it means thinking at multiple levels: what's in a person's head, what happens between people, and what's embedded in a society's rules and institutions.

The Discrimination Triad: Stereotypes, Prejudice, and Discrimination

Must know

Three concepts the MCAT constantly uses together — and that students constantly confuse:

• Stereotype — a cognitive generalization applied to all members of a group, regardless of individual variation. Operates at the level of beliefs. Not inherently hostile (a mental shortcut), but dangerous when applied rigidly.
• Prejudice — an affective (emotional) attitude, typically negative, toward a group based on membership rather than individual assessment (dislike, fear, contempt). Operates at the level of attitudes.
• Discrimination — behavior: unequal or unfair treatment based on group membership. The only one of the three that requires an action.

Think of the triad as stereotype = thought, prejudice = feeling, discrimination = action. You can be prejudiced without discriminating, and discriminate without consciously feeling prejudiced.

Quick check: A hiring manager believes women are less career-committed than men (stereotype), feels annoyed interviewing female candidates (prejudice), and rates female applicants lower than equally qualified men (discrimination). Which layer is the MCAT testing when it asks about "behavior"? — Discrimination.

The Relationship Between Prejudice and Discrimination

Why They Don't Always Go Together

Must know

Prejudice and discrimination do not automatically accompany each other. LaPiere's study (1930s) is the classic demonstration: traveling with a young Chinese couple, LaPiere found they were refused service at only one of 250+ establishments — yet when he later wrote those same places asking whether they'd serve Chinese guests, most said no. Expressed attitudes and actual behavior diverged sharply.

Robert K. Merton formalized this attitude–behavior gap in a four-type typology based on whether someone holds prejudice and whether they discriminate:

Prejudiced?	Discriminates?	Label
No	No	Unprejudiced non-discriminator (All-Weather Liberal)
No	Yes	Unprejudiced discriminator (Fair-Weather Liberal)
Yes	No	Prejudiced non-discriminator (Timid Bigot)
Yes	Yes	Prejudiced discriminator (Active Bigot)

Merton's central point: social norms and situational pressures can decouple attitude from behavior in either direction. A loan officer with no personal bias who follows a discriminatory company policy is a Type 2 (discrimination without prejudice). A prejudiced landlord who complies with anti-discrimination law is a Type 3 (prejudice without discrimination). This is why social policy matters even when you "change hearts and minds" — and why legal constraints can suppress behavior while prejudice persists.

Note on scope: The origins of prejudice (scapegoat, social identity, just-world) and downstream effects (self-fulfilling prophecy, stereotype threat) are covered in the 8B Prejudice/Bias and Stereotypes guides. This guide focuses on discrimination as behavior.

Implicit vs. Explicit Bias

Must know

Explicit bias = attitudes a person is consciously aware of and can report. Implicit bias = unconscious associations that influence behavior without deliberate intent (measured by the IAT). Someone may explicitly endorse egalitarian values while harboring implicit biases — a mechanism by which discrimination occurs even absent overt prejudice.

The Role of Cognitive Dissonance

Know the logic

When someone discriminates in a way that conflicts with their self-image as fair, cognitive dissonance (discomfort from contradictory cognitions) arises, and they rationalize the behavior ("the other candidate was just objectively better") to reduce it. This explains how discrimination persists among people who believe they're unbiased.

Quick check: A manager who considers herself open-minded consistently interrupts female colleagues but not male ones; told this, she insists it was unintentional and that the men's points were more interesting. Which concept explains her rationalization? — Cognitive dissonance: resolving the conflict between her behavior and her self-image as unbiased.

Individual vs. Institutional Discrimination

Individual Discrimination

Must know

Individual discrimination is unequal treatment by a specific person based on bias. It is actor-dependent — remove the biased individual and the behavior stops (e.g., a doctor who dismisses a patient's pain because of racial assumptions). It is visible, attributable, and correctable at the individual level.

Institutional (Structural) Discrimination

Must know

Institutional discrimination (also structural) refers to policies, practices, and laws within institutions that produce unequal outcomes — even absent any individual's prejudice. It does not require conscious intent, is self-perpetuating because embedded in seemingly neutral rules, and produces disparate impact: facially neutral policies that disproportionately disadvantage certain groups.

Passage-level

Canonical examples (recognize the pattern, don't memorize details):

• Redlining: banks/FHA historically denied mortgages to predominantly Black neighborhoods (marked red on maps); wealth gaps persist after the overt policy ended.
• Glass ceiling: an invisible structural barrier blocking women and minorities from top leadership — not one actor but a network of evaluation criteria and cultural assumptions.
• Sentencing disparities and school funding tied to property taxes are similar structural outcomes that persist without any single actor deciding to disadvantage a group.

De jure vs. de facto. De jure discrimination is mandated by law/official policy (e.g., Jim Crow segregation). De facto exists in practice without a law requiring it (custom, residential patterns, neutral rules). Anchor scenarios to by law (de jure) vs. in fact/practice (de facto).

Why the Distinction Matters

Know the logic

It matters for solutions: individual discrimination is addressed through education, bias training, and enforcement against specific actors; institutional discrimination requires structural reform (laws, policies, hiring criteria, funding formulas). Fixing attitudes while structures remain unchanged leaves disparate outcomes intact.

Quick check: A company requires a minimum SAT score for all applicants. No manager expresses bias, yet far fewer Black and Latino applicants advance in a region where school-funding disparities lowered average scores. Individual or institutional? — Institutional: the policy produces disparate impact without any conscious prejudice.

How Power, Prestige, and Class Facilitate Discrimination

Social Power

Must know

Sociologically, discrimination is unequal treatment that is enforceable because one group holds greater social power — the ability to impose one's will, control resources, and decision-making against resistance. Without a power differential, biased treatment may be prejudice but lacks the institutional backing to function as systemic discrimination. This is why sociologists distinguish racism (prejudice + power) from mere racial prejudice: anyone can hold bias, but translating it into systemic disadvantage requires institutional power.

Prestige

Know the logic

Prestige is the social honor and esteem accorded to a person or group. High-prestige groups define what counts as "professional" or "qualified," so hiring managers use prestige markers (elite credentials, names, accents) as proxies for competence, disadvantaging capable candidates from lower-prestige backgrounds. (stigma, from Goffman, is a deeply discrediting attribute that reduces a person "to a tainted, discounted one" — see Common Confusions.)

Social Class

Must know

Social class (income, wealth, occupation, education) both causes and compounds discrimination in two ways:

1. Class as a target itself (sometimes called classism). Class is one of several named targets the MCAT expects as distinct "isms": racism, sexism, ageism, ableism, homophobia/heterosexism.
2. Class intersecting with other identities. Intersectionality (Kimberlé Crenshaw) holds that race, gender, class, sexuality, and disability do not operate independently — they intersect to create overlapping and compounding systems of privilege and discrimination. A Black woman's experience is qualitatively distinct from that of Black men or white women, not simply the sum of the two. Wealth can buffer some forms of discrimination while leaving others (e.g., police profiling) intact.

The counterpart to discrimination is privilege — unearned advantages a dominant group enjoys by virtue of membership, often invisible to those who hold it. Privilege and discrimination are two sides of the same structured inequality.

Know the logic

How power/prestige/class perpetuate institutional discrimination. Dominant groups write the rules of institutions, control access to resources (capital, education, networks), define normalcy (who counts as "qualified"), and suppress challenges (resisters face higher costs). The result is a self-reinforcing cycle: class advantage → institutional power → rules favoring the advantaged → continued advantage.

Quick check scenario: Arjun, a first-generation college student, is equally qualified to Maya, whose parents are alumni of the firm's founders' university. Maya gets the internship via an alumni referral network Arjun can't access. What concepts are illustrated? — Institutional discrimination (the network systematically advantages certain class/prestige backgrounds), social class, and prestige. No individual necessarily acted with prejudice, yet the structure produces unequal outcomes.

The Contact Hypothesis

Know the logic

The Contact Hypothesis (Gordon Allport, The Nature of Prejudice, 1954): contact between groups under certain conditions can reduce prejudice and discrimination. The conditions:

• Equal status between the groups
• Common goals requiring cooperation
• Intergroup cooperation (not competition)
• Support from authority, law, or custom

When met, contact challenges stereotypes and lowers the emotional component of prejudice, reducing the motivation to discriminate. When absent (unequal, competitive, or hostile contact), prejudice can increase. Relevant to school desegregation and workplace diversity initiatives.

Common Confusions & Tricks

1. Discrimination requires behavior, not just attitude.
The most common error: conflating prejudice with discrimination. Feeling negatively = prejudice; acting on it to produce unequal treatment = discrimination.

2. Institutional discrimination does NOT require prejudiced individuals.
If a policy produces disparate outcomes, the discrimination is structural regardless of intent. Watch for "neutral" policies with unequal outcomes — that's the tell.

3. Merton's Type 2 is the most counterintuitive — lock it in.
The "unprejudiced discriminator" (Fair-Weather Liberal): a person can discriminate purely out of conformity, financial incentive, or institutional compliance, with no underlying prejudice.

4. Intersectionality ≠ "adding up" disadvantages.
The intersection creates unique forms of discrimination not captured by either category alone. Crenshaw's argument was that anti-discrimination law failed Black women by treating race and gender separately.

5. Stigma (Goffman) ≠ stereotype.
Stigma is a social identity marker that is deeply discrediting; a stereotype is a cognitive generalization. A positive stereotype ("Asians are good at math") still causes harm but isn't a stigma — stigma marks a person as spoiled or lesser in social standing.

6. The Contact Hypothesis won't work without its conditions.
"Groups A and B are in contact, so prejudice decreases" is a trap. Allport required equal-status, cooperative, authority-supported conditions; forced contact under competitive or unequal conditions can worsen relations.

7. "If you see disparate impact, think institutional discrimination."
Default heuristic: a facially neutral policy producing statistically unequal outcomes across groups → institutional/structural discrimination.
