Steele, C.M., & Aronson, J. Stereotype vulnerability and the intellectual test performance of African-Americansm JPSP, in press

Stereotype vulnerability is being at risk of confirming a stereotype. In a induced position of vulnerability, blacks underperformed vs whites when the test was stated as diagnostic. In fact, mere salience of the stereotype could impair black's performance even when the test wasn't ability diagnostic.

When blacks take tests, they run the risk of confirming a negative social stereotype about blacks intellectual ability. This threat may interfere with performance. Over time it may cause people to "disidentify" with achievement in school and other intellectual domains and reduce their motivation and interest in it.

Blacks have higher dropout rates and lower grades than whites. But standardized tests seem to be as predictive for blacks as whites. Blacks perform less even when they have the same preparation.

Other studies showed that blacks performed better on an IQ test when told it was a hand-eye coordination test. Being a token member of a group can inhibit memory. Performance worsens when attention is also directed to another concern (like perception of performance in light of devaluing stereotype).

Study 1
Black and white students took part of the verbal GRE. One group was told it was a intellectual ability test, another told it was a problem solving test. The results confirmed that blacks performed worse when told the test evaluated ability (and blacks in general performed less than whites). Black subjects thought the test was more biased than white subjects. Their performance matched whites when the test was non-ability.

Study 2
Same as first study, except students complted anxiety questionnaires after the test. The results confirmed the first study. No effect on anxiety. Blacks completed fewer questions than whites.

Study 3
This study subjects completed a stereotype questionnaire after being told they would take the GRE test (same three conditions as before). The results showed that inducing of stereotype thoughts caused blacks to have more self-doubt and desire to avoid stereotype behavior. They exhibited stereotype vulnerability. They made advance excuses for their performance.

Study 4
This study followed like study one, except in one condition the subjects merely indicated race, and the other they did not. The results confirmed that merely priming for race caused worse performance (with performance equal to whites in the non-prime condition). Post questions showed no difference in perceived performance or ethnicity effects.

It appears that stereotype vulnerability causes inefficiency in cognitive processing, probably due to increased self-significance of their frustration.

Implications
Stereotype vulnerability may help explain the near 200 point gap between whites and blacks.
