> The snarky "checkmated by FACTS, you emotional liberal!" narrative doesn't work when STUDY after STUDY fails to find any meaningful correlation

I think you're the one constructing a narrative. From what I'm aware of, there IS a correlation between race and IQ, and it is strong. And it is borne out by study after study. Stronger than the effects of environment and education. Even in the famous Minnesota transracial twin study where adopted black children are raised by wealthy white parents, " the IQs of adopted black children reared by white families did not differ significantly from that of black children raised by their biological parents."
