The results of Experiment 5. Zero denotes accurate estimates, positive values denote overestimation, and negative values underestimation. In the Black American minority condition, the overall percentage of Black American faces was 25%. In the White American minority condition, the overall percentage of Black American faces was 75%. In both conditions, the participants were asked to estimate the prevalence of Black American faces (red) and White American faces (yellow). In both conditions, the participants overestimated the minority group and underestimated the majority group. However, the magnitude of the effects in the White American minority condition was significantly smaller, denoting the role of prior social knowledge.
