This data originates from the publicly available implicit association test (IAT) on racial prejudice hosted by Project Implicit. 200 participants were randomly sampled from the full trial-level data available for participants from 2002 to 2022. We included only those IAT blocks relevant to scoring (3,4,6,7) and only individuals with full data.
