Women's underrepresentation in academic fields and professions emphasizing high intellectual talents persists as a prominent societal issue. To explore early antecedents of this gender imbalance, the present study investigated the developmental changes in children's social preference of boys and girls who pursue brilliance-required (vs. effort-required) activities. Importantly, we took an intersectional perspective to explore whether children consider target race in their social preference. Five- to 9-year-old U.S. children (N = 207; M[subscript age] = 7.53; 104 girls and 103 boys; 48% White) were presented with pairs of Asian, Black, and White characters matched in gender. One character was depicted as enjoying a game requiring high intellectual talents and the other enjoyed a game requiring effort. Participants were then asked to choose the character that they liked more, as an indicator of their social preference. With age, children became increasingly likely to prefer White boys and girls of color (i.e., Black and Asian girls) pursuing activities requiring brilliance (vs. activities requiring effort). In contrast, children did not develop increasing social preference for White girls or boys of color who opt in for brilliance-required activities. Our data suggest that, as early as elementary school years, children's social preference in contexts valuing sheer brilliance becomes both gendered and racialized. These findings highlight the importance of using an intersectional approach to identify the specific developmental processes that contribute to social disparities in brilliance-required contexts.
