Questions: In-Groups, Out-Groups, and Social Boundaries

Question 1

In Tajfel's minimal group paradigm, participants showed in-group favoritism even when groups were formed by: coin flip, random assignment, or preference for one abstract painter. This finding is theoretically significant because it shows that in-group favoritism:

• A. Requires competition for scarce resources to emerge
• B. Emerges from mere social categorization, without history, competition, or material stakes
• C. Is learned from parents and cultural socialization rather than being psychological
• D. Only occurs when group members interact face-to-face over time

Answer: (B)

The minimal group paradigm was designed to strip away all the usual explanations for intergroup bias — shared history, material competition, face-to-face interaction — to find the minimum condition that produces favoritism. The finding that even trivial, arbitrary categorization generates resource allocation favoring the in-group suggests that social identity itself — the part of self-concept derived from group membership — is sufficient motivation. This challenges resource-competition theories of prejudice and points to identity processes as the root cause.

Question 2

Which scenario best illustrates how discrimination can persist in a society without requiring individual hostility toward out-group members?

• A. A manager who explicitly states she prefers not to hire members of a particular ethnic group
• B. Historical laws that formally exclude minorities, now acknowledged as unjust
• C. Informal hiring networks that draw from socially segregated pools, producing differential outcomes without deliberate exclusion
• D. A neighborhood association that votes explicitly to exclude out-group residents

Answer: (C)

Structural discrimination operates through institutional arrangements that produce differential outcomes without requiring anyone to act from explicit prejudice. When informal hiring networks draw from socially segregated social circles, or when housing markets channel different groups into different neighborhoods through seemingly neutral price mechanisms, the structural features reproduce inequality. Individual actors may have no hostile intent while the system as a whole generates the same outcomes as deliberate exclusion. Options A, B, and D all involve explicit intentional discrimination.

Question 3

In-group favoritism requires competition over scarce resources — when groups have no material stake in each other, they treat most groups equally.

• T. True
• F. False

Answer: False

The minimal group paradigm directly refutes this. When groups are assigned arbitrarily and there is no shared history, no material competition, and no face-to-face interaction, participants still allocate more resources to in-group members. Social identity theory explains this: maintaining a positively-valued group identity is itself motivating, independent of material interests. People favor their in-group partly because doing so affirms who they are — group membership is part of self-concept, and favoring the group favors the self.

Question 4

Prejudice involves distorted perception of out-group members, including overgeneralizing from limited cases and applying group stereotypes to individuals even when evidence contradicts the stereotype.

• T. True
• F. False

Answer: True

This accurately describes the perceptual distortions that constitute prejudice. It is not merely negative affect toward a group but a cognitive pattern: overgeneralizing from a few representatives, treating group membership as more diagnostic than individual characteristics, and failing to update when out-group members violate the stereotype. These distortions are sustained by selective attention (noticing stereotype-confirming behavior) and attributional asymmetry (attributing in-group positives to character, out-group positives to luck).

Question 5

What does the minimal group paradigm demonstrate about the psychological basis of in-group favoritism, and why is this finding theoretically important for understanding prejudice and intergroup conflict?

Model answer: The minimal group paradigm shows that the mere act of being categorized into a group — even arbitrarily, with no shared history, material stakes, or interaction — is sufficient to produce favoritism toward in-group members. This means that social identity itself (the part of self-concept derived from group membership) is the fundamental psychological driver, not resource competition or accumulated grievance. The theoretical importance is that it rules out purely material explanations for prejudice: intergroup bias can emerge wherever social categories exist, regardless of whether groups actually compete. This implies that reducing competition alone is insufficient to eliminate prejudice — the identity processes underlying categorization must also be addressed.

The finding has direct implications for interventions. If favoritism requires only categorization, then any context that makes group boundaries salient (uniforms, team names, demographic labels) can activate intergroup bias. Interventions that work only on material inequalities leave the identity-based mechanism intact. Social identity theory, built largely on this finding, suggests that recategorization (creating superordinate shared identities) or individuation (reducing the salience of group categories) may be more effective than resource redistribution alone.
