The theory of stereotype threat was developed to account for
persistent minority underachievement in American colleges and
universities. It hypothesizes that members of minority groups underperform
academically because of unconscious fears of living up to negative group
stereotypes. While evidence pertaining to stereotype threat has been
positive, it mostly comes from small experimental studies of selected
undergraduate subjects at a few universities. In this paper we test the
theory of stereotype threat on a large, representative population of
college and university students. Using data from the National Longitudinal
Survey of Freshmen, which surveyed nearly 4,000 students at twenty-eight
academic institutions, we construct scales to measure stereotype threat
and use them to predict grades. We uncover a clear process of
disidentification in response to minority stereotyping and show how it,
along with other theoretically specified mechanisms, undermines the grade
performance of minorities.
