Individual genomic admixture and cognitive ability

So, I posted this: Abstract We used data from the PING study (n≈1200) to examine the relationship between cognitive ability, socioeconomic outcomes and genomic racial ancestry. We found that when genomic ancestry was not included in models, self-reported race/ethnicity (SIRE) was a useful predictor of cognitive ability/S, but when genomic ancestry was included, SIRE lost much or most of its validity. In particular, for African Americans, the SIRE standardized beta changed from about -1.00 to .20. European genomic ancestry was found to be positively related to cognitive ability/S (r's .26/.33) including when SIRE was controlled, while African genomic ancestry was found to be negatively related to cognitive ability/S (r's-.36/-.30) also when SIRE was controlled.
