You’re right that the black-white IQ gap grows as children age, but this is easily explained by the fact that intelligence becomes more heritable as one gets older.

Ahaha oh wow.

See the Minnesotta transracial adoption study for more information:

Not that one again. It’s been debunked over and over again. Try this for just one refuting.

You sound like a creationist.

You’re the one parroting canards, mate.

(I know I promised you some references more credible than The Bell Curve, but I’ve been too busy to go back to those books lately, and frankly, they’re all over the internet if you’re that interested. If you steer clear of both Gould and Herrnstein you should be fine.)

And please do some more research on race and intelligence before making authoritative claims, such as that the gap is entirely environmental. You sound like a creationist.

It’s true, though, that it’s not just socio-economics, but also cultural, as evidenced by the fact that black kids doing as well on tests as white kids in grade 1 tend to do much worse than those same kids by grade 6, at least in the US. There’s a strong anti-intellectual streak to American black culture, which naturally translates to lower average IQ scores. There’s more to “class” than a parent’s income.
If anything, this would be a better candidate to explain your putative growing difference, but that’s just not there.

That’s an utter lie. There is simply no evidence that the black-white IQ gap disappears when income is controlled. In fact, the gap grows as income grows, a phenomenon explained by regression towards the mean.
