Examining the effects of genetic ancestry information on appraisals of contested racial identities

The increasing accessibility of DNA ancestry information may influence perceptions of others' and one's own racial identity. The current work tested whether the presence of genetic testing information influenced Black participants' perceptions of individuals who claim a mismatched racial identity (i.e., a racial identity that differs from their parents), and whether these perceptions are moderated by the amount of corroborating DNA evidence and racial claim of the target.

Black participants (N = 1,041) were randomly assigned to read about an individual claiming a Black or White mismatched racial identity. The target either had a majority amount (71%) of corroborating genetic information, a minimal amount (29%) or made no mention of genetic information.

When a majority percentage of corroborating genetic information was provided, participants evaluated Black-identified targets more favorably than White-identified targets. Additionally, Black-identified targets were evaluated most favorably when they had a majority amount of corroborating genetic information.

Among Black perceivers, a majority amount of corroborating genetic information increased positive evaluations of a mismatched, Black-identified racial claim. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
