Over at Tacitus godless & I have been having a little dialogue with dissenters from the position that GNXP offers a different and valid viewpoint than normally mooted in “respectable” circles. In any case, one of the commenters brought up the Eyfurth study that showed that black-white mixed children in post-World War II Germany had about the same IQs as white children whose fathers were also servicemen. The study is very interesting and suggestive, because it contradicts the Minnesota Transracial Adoption Study that showed interracial twins adopted who were of mixed-race had IQs between that of black and white adoptees.
Jensen in The G Factor has a few quick responses:
- The fathers’ IQs are not accounted for, and it could be that both groups of servicemen, black & white, were not representations of the mean in their parent populations. Jensen notes that 30% of blacks vs. 3% of whites were rejected during preinduction because they failed mental tests.
- Factors that influenced assortive mating were not tracked. For instance, low SES German women might have had equal preferences for high IQ black officers and low IQ white privates because intelligence could have overcome racial bias in the former case while there was a preference for the latter because they understood that their children might be less ostracized by society if they were not racial minorities.
- The tests were taken during pre-adolescent years when correlation between IQ scores and genotype is lower than in later years.
- Heterosis, or hybrid vigor, could have bridged some of the gap.
In any case, let’s ignore these factors, and address the topic. Flynn, of the Flynn Effect fame, suggests that something in American society (prejudice, racism, etc.) might be influencing parents to treat their black adoptive children differently than they would white children. And yet it seems that if this is the cause than though situation is not totally analogous (white biological mothers of mixed-race children), we should look toward post-World War II Germany to solve some of the problems America has in socializing its black youth [1]. Additionally, we might also investigate how white parents treat their adopted Asian children, because these youth display no ill effects of racism, but rather, often score higher on IQ tests than white children.

[1] I do not by this suggest that we should institute a total racial state, liquidate our Jews, and prepare to deal with a massive invasion by the civilized nations that will destroy the heart & soul of our volk to purge our racist souls!
