If by IQ you mean one’s performance on IQ tests, rather than the g-factor they seek to measure, there isa not-so-implausible mechanism by which racism can affect the former.
your stem cells don’t go out and check other people’s opinions of your ethnic background before they develop into a central nervous system
IAWYC but children retain lots of neuroplasticity even after their central nervous system has developed, and even adults do a little bit.
I meant g in that sentence, yes. The bit about motivation later was alluding to stereotype threat and similar effects.
Point taken re: neuroplasticity. It doesn’t seem likely that that’s an overwhelmingly large contributor to adult intelligence, but correlation between adult and childhood IQ scores isn’t so high that it couldn’t be playing a role. I’d be interested to see how that correlation changes between populations, now.
