Samtidigt: "A key point in their argument is their contention that scores on the Armed Forces Qualifications Test (AFQT) represent ‘‘achievement’’ scores and that the AFQT is qualitatively different from purported true ‘‘IQ’’ score data also available in the NLSY79. This contention is based on both conceptual argument and empirical analysis of NLSY79 data. This comment disputes their contention on both grounds... Our results suggest that as an empirical matter, the AFQT test and the group ‘‘IQ’’ tests in the NLSY79 data behave in a similar fashion. Given the murky conceptual distinctions between the AFQT and these ‘‘IQ’’ tests, these empirical results are not surprising."
Så ja, AFQT och intelligenstesten skiljer sig inte åt (såklart, korrelationen är 0.8 och de mäter exakt samma sak, nämligen g-faktorn).

Det var inte det jag menade utan sista stycket på sidan 12 i Black Americans Reduce the Racial IQ Gap: Evidence from Standardization Samples
"The constancy of the black/white IQ gap is a myth. Blacks have gained 5 or 6 IQ points on whites over the last 30 years. Neither changes in the ancestry of those classified as black nor changes in those who identify as black can explain more than a small fraction of this gain. Therefore, environment has been responsible. The last two decades have seen both positive and negative developments: gains in occupational status and school funding have been accompanied by more black preschoolers in single-parent homes and lower income in those homes(Neal, in press). We believe that further black environmental progress would engender further black IQ gains."
Nå, är vi överens om Flynns och Dickens slutsatser i ovannämnda stycke?

Tror dock du blandar ihop förändringar i intelligens hos barn, som vi vet kan ändra sig, och vuxna. Flynn skriver ju själv att skillnaden fortfarande är runt 1.1SD i 20-årsåldern. Vilket är det vi diskuterar. Skall vi enas om det?
