The authors explored how negative intergroup comparisons affect intergroup
differentiation. More specifically, they tested the prediction that the in-
group's negative intergroup comparisons with a high-status group would resu
lt in more negative stereotyping of a lower status out-group. The authors e
licited stereotypes of a lower status university in 2 conditions. In the Is
t, the participants judged only the middle-ranking university in-group and
a lower status university. In the 2nd, those judgments followed comparison
with a higher status university. In the 2nd condition, there was an increas
ed differentiation between the in-group and the lower status out-group beca
use of the more negative stereotyping of the lower status out-group. This e
vidence of intergroup differentiation was found only on the dimension judge
d most important and along which the ingroup was negatively compared with t
he higher status group.
