Questions: Minimal Group Paradigm and Ingroup Bias

Question 1

In a minimal group study, participants must allocate points between anonymous ingroup and outgroup members. They are given a choice: (A) 7 points to ingroup / 1 to outgroup, or (B) 12 to ingroup / 11 to outgroup. Many participants choose option A. What does this reveal about the underlying motivation?

• A. Participants want to maximize their ingroup's welfare, so they avoid option B's higher outgroup allocation
• B. Participants are motivated by positive distinctiveness — maintaining a relative advantage over the outgroup, even at cost to their ingroup's absolute gain
• C. Participants are punishing outgroup members by minimizing their points
• D. The allocation task is too abstract, so participants just pick the simpler-looking option

Answer: (B)

Option B gives the ingroup more in absolute terms (12 vs. 7), yet many participants chose A. This reveals the motivation is not 'help my group get as much as possible' but 'make my group look better than the other group.' Positive distinctiveness — a favorable relative comparison — is the goal, consistent with social identity theory. Participants sacrifice absolute ingroup gains to preserve a larger gap between 'us' and 'them.'

Question 2

A researcher argues that to produce genuine ingroup bias in the lab, she must first create real competition for a scarce resource between the groups. Based on the minimal group paradigm, what is wrong with this assumption?

• A. Nothing — resource competition is necessary for reliable intergroup discrimination
• B. She is partially right — competition is needed, but it can be symbolic rather than material
• C. Ingroup bias emerges from mere categorization alone — no competition, history, or material stakes are required
• D. Resource competition actually reduces ingroup bias by directing attention toward the resource rather than group identity

Answer: (C)

The minimal group paradigm's central finding is that categorization alone — even by trivial criteria, with no competition, no interaction history, and no material benefit — produces systematic ingroup favoritism. Tajfel's results directly challenged the 'realistic conflict theory' view that competition is a prerequisite for intergroup discrimination. The assumption that conflict is necessary reflects a failure to grasp how minimal the conditions for bias really are.

Question 3

In minimal group experiments, participants show ingroup favoritism even though they will never meet their ingroup members, receive no personal benefit from favoring them, and the group assignment was arbitrary.

• T. True
• F. False

Answer: True

This is exactly the point of the paradigm — to identify the minimum conditions for discrimination. Participants receive no reciprocation, no interaction, and no material gain. The favoritism is purely symbolic, driven by the motivation to maintain a positive social identity through favorable intergroup comparison. The psychological floor for bias requires nothing more than knowing which category you belong to.

Question 4

The minimal group paradigm implies that real-world intergroup prejudice is as arbitrary and easily reversed as laboratory group assignments.

• T. True
• F. False

Answer: False

The paradigm identifies a floor — the baseline bias activated by categorization alone — not a ceiling. Real-world discrimination is built on this floor but amplified enormously by historical context, ideology, material interests, power differentials, and cultural meaning. The finding is troubling precisely because it shows the baseline is already biased before any of those factors are added; it does not imply that all discrimination is superficial or easily reversed.

Question 5

If categorization alone triggers ingroup bias, what does this imply about strategies for reducing real-world intergroup discrimination?

Model answer: Bias cannot be eliminated by simply removing explicit hostility or resource competition — it is activated by the mere existence of salient social categories. Effective strategies must work actively against this default: equal-status contact with cooperative interdependence (the contact hypothesis), recategorization under a superordinate identity, or cross-cutting identities that reduce the salience of the problematic category. Passive approaches (teaching that differences are meaningless while categories remain salient) are insufficient. The minimal group baseline means interventions must be active countermeasures, not just the absence of conflict.

This is why anti-discrimination efforts that focus only on explicit prejudice — overt hostility, deliberate stereotyping — often leave implicit bias untouched. The categorization-triggers-bias dynamic operates automatically. Effective approaches target the conditions under which categories activate: when groups are in competition versus cooperation, when superordinate identities are salient, and when institutions reinforce or counteract category-based differential treatment.
