"They observed all the typical findings: a 1.10 Hedge’s g gap in intelligence between Blacks and Whites; Whites were 98% European and Blacks were 72% African; and admixture mediated 75.68% of the difference in intelligence between Blacks and Whites, as indicated by the 0.18 correlation within the Black group."

Might be worth pointing out that when black immigrants were excluded(and probably a specific definition of black american, so excluding those who identified as black and another SIRE group), almost 100% was mediated with MCGFA(with means of 98% and 17% and a standard deviation of 10%, there is a difference of admixture of 8.1 sd, and thus with a correlation of 0.13 within

non-immigrant black americans, a 1.053 d gap can be explained by admixture, compared to a 1d/1.08g gap in this sample). Source:(https://www.researchgate.net/publication/354766954_Genetic_ancestry_and_general_cognitive_ability_supplpdf).

Cremieux, had to post this here because I didn't know if you'd be notified of my comment on Aporia magazine.

This large Dutch study found that children of same-sex couples performed better in school tests: https://journals.sagepub.com/doi/full/10.1177/0003122420957249

No mention of genes in it, but seems like genetic selection for intelligence. The media were hyping it as evidence gay parents are better. I think it's more like lesbian couples get to pick a sperm donor and choose wisely. I think if gay couples were to always use surrogates and pick intelligent and stable sperm/egg donors, they'd be quite eugenic. Note the small number of gay male couples with kids though (although the paper does highlight some additional reasons for why this is, I suspect most gay men have no interest in kids, kind of makes me think the whole moral panic about gay men and kids is a bit overblown...)

Anyway this study could be worth discussing at some point. The sociology journal isn't going to get into how genes might influence outcomes, naturally.
