Walton and Cohen

When a negative stereotype impugns the ability or worth of an outgroup, people may experience stereotype lift—a performance boost that occurs when downward comparisons are made with a denigrated outgroup. In a meta-analytic review, members of non-stereotyped groups were found to perform better when a negative stereotype about an outgroup was linked to an intellectual test than when it was not (d=.24,p<.0001). Notably, people appear to link negative stereotypes to evaluative tests more or less automatically. Simply presenting a test as diagnostic of ability was thus sufficient to induce stereotype lift. Only when negative stereotypes were explicitly invalidated or rendered irrelevant to the test did the lift effect disappear.
