8.5 Prejudice, Stereotypes, Stigma & Discrimination

The AAMC treats intergroup bias across two content categories: 8B supplies prejudice, stereotypes, stigma, and ethnocentrism, and 8C supplies discrimination. Passages in this area are nearly always health-equity framed — differential pain management, differential referral rates, differential screening uptake — and the questions demand that you assign a phenomenon to the correct component. Getting the three-way split right resolves most of the item.

The Three Components of Intergroup Bias

The relationships are not deterministic, and the MCAT tests this. Prejudice can exist without discrimination (an internally biased clinician who scrupulously treats everyone identically), and discrimination can exist without prejudice (a scheduling algorithm that disadvantages a group while every operator holds egalitarian attitudes). Do not select an answer that treats them as equivalent.

Processes That Contribute to Prejudice

The AAMC names three drivers explicitly.

1. Power, Prestige, and Class

Prejudice is generated and maintained by struggles over scarce resources. Realistic conflict theory holds that competition between groups for limited resources produces hostility, while cooperation on shared superordinate goals reduces it — the classic Robbers Cave demonstration. Groups with greater power, prestige, and class advantage possess the means to encode their prejudice into institutions, which converts attitude into structure.

2. The Role of Emotion

Scapegoating channels frustration and blame onto a low-power out-group, following the frustration-aggression pathway. Threat, fear, and disgust are the emotions most reliably linked to intergroup hostility, and prejudices that are emotionally rather than informationally grounded are notably resistant to corrective facts.

3. The Role of Cognition

Prejudice is also a byproduct of ordinary cognitive economy. People sort the social world into in-groups (the group one identifies with) and out-groups, then apply out-group homogeneity bias — perceiving out-group members as far more alike one another than in-group members are. Categorization is efficient, which is precisely why stereotyping is so persistent.

Stereotypes and Their Downstream Processes

Self-Fulfilling Prophecy

A self-fulfilling prophecy occurs when an initially false expectation causes behavior that makes the expectation come true. The mechanism runs through the perceiver:

1. The perceiver holds an expectation about the target.
2. The perceiver behaves differently toward the target because of it.
3. The target responds to that altered treatment.
4. The target's response confirms the original expectation.

The Rosenthal and Jacobson "Pygmalion in the classroom" studies illustrate it: teachers told that certain randomly selected students were poised for an intellectual growth spurt gave those students more attention and challenge, and those students subsequently gained more. The critical exam point is that the causal engine is the perceiver's changed behavior, not the target's inner state.

Stereotype Threat

Stereotype threat (Claude Steele) is the situational anxiety of confirming a negative stereotype about a group one belongs to, which itself impairs performance on stereotype-relevant tasks. It is distinct from self-fulfilling prophecy in three ways that the MCAT exploits:

• The mechanism runs through the target's own apprehension and consequent working-memory load, not through a perceiver's differential treatment.
• It does not require the target to believe the stereotype; people who explicitly reject it still show the effect.
• It is triggered by cues in the situation — being asked to record one's demographic group before a test, being the sole member of one's group in the room, or being told the task is diagnostic of ability. Removing the cue removes the effect.

Applied example: a female medical student who is the only woman on a surgical rotation underperforms on a technical assessment framed as measuring "natural surgical aptitude," but performs normally when the same task is framed as a practice exercise. That is stereotype threat, not lack of preparation.

Stereotype boost or lift is the mirror phenomenon in which a positive in-group stereotype or a downward comparison enhances performance.

Stigma

Stigma (Goffman) is a deeply discrediting attribute that reduces a person "from a whole and usual person to a tainted, discounted one." Goffman's categories are frequently tested:

• Abominations of the body — visible physical deformities or disfigurement.
• Blemishes of individual character — attributes such as addiction, incarceration history, or mental illness.
• Tribal stigma — stigma attached to race, nation, or religion and transmitted across a lineage.

Also distinguish enacted stigma (actual experienced discrimination) from felt or internalized stigma (the anticipation of it, and the shame absorbed from it). Internalized stigma is a principal driver of delayed care-seeking in mental illness and HIV, and it connects directly to Cooley's looking-glass self.

Ethnocentrism vs. Cultural Relativism

• Ethnocentrism: judging another culture by the standards of one's own and presuming one's own superior. In medicine it manifests as dismissing a family's traditional healing practices as merely ignorant.
• Cultural relativism: evaluating a culture's beliefs and practices within that culture's own context and logic. It is the analytic stance underlying culturally competent care.

Do not confuse either with xenophobia (fear or hatred of foreigners) or with cultural competence (the applied clinical skill).

Discrimination: Individual vs. Institutional

This distinction dominates health-disparities passages and is worth memorizing precisely.

Because institutional discrimination needs no prejudiced actor, an answer choice asserting that a disparity "must reflect provider bias" is almost always wrong when the passage describes a structural policy. The related idea of structural or systemic discrimination extends this across multiple interlocking institutions — housing, education, employment, and health care compounding one another.

Finally, power, prestige, and class facilitate discrimination by determining who can make their prejudice consequential. Prejudice held by a group without institutional power produces interpersonal friction; the same prejudice held by a group controlling admissions, lending, hiring, or triage produces structured inequality.

Exam Traps to Avoid

• Stereotype threat requires no belief in the stereotype. Reject answer choices claiming the target must internalize it.
• Self-fulfilling prophecy runs through the perceiver; stereotype threat runs through the target. This is the single most common confusion in this content area.
• Discrimination is behavior. An unexpressed attitude is prejudice, not discrimination.
• Institutional discrimination can be intent-free. Do not require a villain.
