Differential validity and differential prediction analyses have come to conflicting conclusions regarding whether the relationship between cognitive ability tests and performance is the same across racial/ethnic subgroups. A prominent criticism of differential validity analyses is that they are confounded by subgroup differences in the ratio of criterion-to-test standard deviations (SDs). We investigated whether subgroup differences in these ratios can account for this conflicting evidence. Drawing on data from over 1 million participants, we find that subgroup differences in criterion-to-test SD ratios in general only account for a relatively small portion of subgroup differences in test-criterion correlations.
