Intergroup Competition
When distinct groups clash over resources or status, intergroup competition fuels in-group loyalty and out-group hostility, shaping political coalitions and social identity.

Intergroup competition refers to the rivalry or conflict between distinct social groups striving for resources, status, or dominance. It arises from contrasting values, identities, or goals and often triggers psychological rewards for in-group members while fostering hostility toward out-groups. This dynamic is a core mechanism in social psychology, influencing group cohesion, political coalitions, and societal stratification.
What this means in real life
During a school sports tournament, students cheer loudly for their house team and boo the rival house, even though both groups attend the same school and will socialize together tomorrow.
What it isn’t
It is not simply disagreement between individuals. Intergroup competition requires people to identify as members of distinct groups and prioritize group outcomes—a single argument between two people is interpersonal conflict, not intergroup.
Commonly misused online
Often conflated with healthy rivalry or friendly competition; social media amplifies it by framing any group-based disagreement (fandoms, political supporters, gaming communities) as inherently divisive, when mild competition can coexist with respect.
