Title:
The Black White IQ gap in the total sample of the Vietnam Experience Study

Abstract:
IQ differences were examined between Blacks and Whites in a large Vietnam era sample (Vietnam Experience Study; total n ≈ 10,800). Relative to a White IQ of 100 and SD of 15, Blacks obtained a mean IQ of 85 and an SD of 12.
An attempt to examine measurement invariance using multi-group confirmatory factor analysis failed with impossible estimates and very poor fits. A simpler approach of examining the correlation matrices by group showed that the White correlations were stronger, sometimes by a lot. Possible reasons for this were discussed.

Key words:
Black, White, Vietnam Experience Study, race difference, IQ, intelligence, cognitive ability, measurement invariance, multi-group confirmatory factor analysis, MGCFA
