Prejudice and Discrimination

MCAT trap: Conflates prejudice (attitude) with discrimination (behavior), assuming they always co-occur. Prejudice is an attitude (affective/cognitive) while discrimination is behavior; they can dissociate — one can hold prejudiced attitudes without discriminating, or discriminate without conscious prejudice.

Prejudice and discrimination are conceptually distinct, and the MCAT exploits that distinction constantly. Prejudice is an attitude — it has affective components (feelings) and cognitive components (beliefs/stereotypes). Discrimination is behavior — the actual differential treatment of people based on group membership. The exam will give you a scenario and ask you to classify it, or give you a research finding where the two dissociate and ask you to explain why. Racism and sexism aren't just individual attitudes on this exam — they also refer to institutional patterns of differential treatment, which is a separate layer students often miss.

The MCAT loves to test Allport's contact hypothesis and Sherif's Robbers Cave experiment together because they both address prejudice reduction but through different lenses. Contact hypothesis tells you that intergroup contact only reduces prejudice under specific conditions: equal status between groups, common goals, intergroup cooperation, and institutional support. Robbers Cave operationalizes this by showing that superordinate goals — challenges that force groups to cooperate — were the only thing that actually reduced conflict between the Eagles and Rattlers. Neither separation nor non-competitive contact worked.

What makes this tricky is that both concepts are frequently oversimplified. Students assume more contact automatically means less prejudice, or that the Robbers Cave groups just needed a cool-down period. Passage-based questions will describe an intervention — say, a school integration program — and ask whether it satisfies the contact hypothesis criteria. You need to evaluate each condition specifically, not just ask 'did the groups interact?' That's where points are won or lost.

Common misconceptions

Common mistake
Wrong: Prejudice and discrimination are the same thing because one always leads to the other.
Right: Prejudice is an attitude (affective/cognitive) while discrimination is behavior; they can dissociate — one can hold prejudiced attitudes without discriminating, or discriminate without conscious prejudice.
Prejudice is an internal attitude — a negative evaluation of a group based on affect or cognition — while discrimination is an external behavior — actually treating people differently based on group membership. These can dissociate in both directions: a prejudiced person might not discriminate due to social pressure or legal constraints, and a person can discriminate through institutional systems (like biased hiring algorithms) without consciously holding prejudiced beliefs. When the MCAT presents a scenario, ask yourself explicitly: is this about what someone thinks/feels, or what someone does?
Common mistake
Wrong: Simply increasing contact between groups is sufficient to reduce prejudice.
Right: Allport's contact hypothesis requires equal status, common goals, intergroup cooperation, and institutional support — mere contact without these conditions can reinforce prejudice.
Allport's contact hypothesis is not 'contact reduces prejudice' — that's the oversimplification that gets students wrong answers. The full hypothesis states that contact reduces prejudice only when four conditions are met: the groups must have equal status in the contact situation, they must share common goals, the contact must involve genuine intergroup cooperation (not just proximity), and it must receive institutional support. In many real-world settings — like forced desegregation without structural support — contact actually reinforces prejudice because the conditions aren't met. Always check all four boxes.
Common mistake
Wrong: In Robbers Cave, intergroup conflict was reduced simply by separating the groups after competition.
Right: In Robbers Cave, only the introduction of superordinate goals (shared challenges requiring cooperation) reduced intergroup conflict; mere separation or non-competitive contact was insufficient.
In Robbers Cave, Sherif first created two groups (Eagles and Rattlers), then introduced competition to generate hostility, then tried multiple ways to reduce that hostility. Mere separation didn't work. Non-competitive activities like watching movies together didn't work. What worked was superordinate goals — situations where both groups needed each other to solve a problem neither could solve alone, like a broken water supply. This is the experimental demonstration that cooperative interdependence, not just reduced competition or distance, is what breaks down intergroup hostility.

What the exam tests

  1. Distinguish prejudice as an attitude (with affective and cognitive components) from discrimination as a behavior, and recognize that racism and sexism can operate at an institutional level beyond individual attitudes.
  2. Apply Allport's contact hypothesis by identifying all four required conditions — equal status, common goals, intergroup cooperation, and institutional support — and recognize that contact alone is not sufficient.
  3. Read a passage describing a prejudice-reduction program and evaluate whether each condition of the contact hypothesis is actually satisfied by the intervention described.
  4. Recall the design of Sherif's Robbers Cave experiment and explain what it demonstrated: that only superordinate goals (not separation or passive contact) reduced intergroup hostility.

Can you avoid these mistakes?

A hospital system's data shows that Black patients are prescribed fewer pain medications than white patients with identical diagnoses, but surveys of physicians show no significant difference in explicit racial attitudes. Is this prejudice, discrimination, or both? How do you classify it, and what concept explains the gap?
A community center designs a program where teenagers from two rival neighborhoods work together on a mural project. The coordinator says it satisfies the contact hypothesis. What four criteria do you need to verify before agreeing — and what would disqualify it?
In the Robbers Cave experiment, after the competitive phase, Sherif had both groups attend a Fourth of July party together. Intergroup hostility didn't decrease. What does this tell you about what is and isn't sufficient for prejudice reduction, and what intervention did ultimately work?
Someone holds strong negative stereotypes about a particular ethnic group but never acts on them in hiring decisions because their company has strict anti-discrimination policies. Is prejudice present? Is discrimination present? What does this example illustrate about the attitude-behavior relationship?
