Stereotype accuracy: Estimating the academic performance of ethnic groups

The authors investigated the accuracy of stereotypes of the academic performance of ethnic groups. Ninety-four participants estimated the mean academic performance of Toronto high school students from nine ethnic groups and completed measures of right-wing authoritarianism, intelligence, and attitudes toward the groups. The estimated academic performance means were compared with the true means as derived from data published by the Toronto Board of Education. These comparisons revealed that, on average, participants were fairly accurate in their perceptions of both the relative standings of groups and the magnitude of between-group variability. Underestimation of between-group variability was associated with lower authoritarianism, whereas overestimation of between-group variability was associated with lower intelligence. Attitudes toward a group were significantly correlated with estimates of the group's mean academic performance, but only for the three groups whose mean academic performance levels were significantly over- or underestimated by participants overall.
