competition for the prize (limited resource) caused the boys to display aggressive behaviour and conflict, for example one group destroyed the other group's flag
the groups were given superordinategoals (such as fixing the water supply, pulling a stuck truck out of mud and coming together to buy a film), then they began to sit together at lunch
doesn't explain how prejudice forms in the absence of competition -> theory depends on on conflict for limited resources
Tajfel (1970)
discrimination occurred when there was no competition suggesting not all prejudice stems from competition over limited resources
Applications of RCT
views on immigration -> immigrants enter a country and may be prejudiced against because they see them as competition for limited resources such as jobs (intergroup conflict)
covid - countries came together to create treatments and vaccines (superordinate goals -> intergroup harmony)
