Reframed, the study seemed to find (a) black kids are adopted less readily and (b) the longer a kid spends in the foster system, the lower their IQ at 17. (There is also limited controlling for epigenetic factors because we didn’t understand those well in the 1970s and 80s.)
Based on how new human cognition is, and genetically similar human races are, it would be somewhat groundbreaking to find an emergent complex trait like IQ to map to social constructs like race, particularly ones as broad as American white and black. (There is more genetic diversity in single African tribes than in some small European countries. And American whites and blacks are all complex hybridized social categories.)

Which is what we all mean by race, anyways.
The latter is more genetically diverse than any other human population by an incredible margin. Making generalized statements about them is impossible (including this one). As for African American populations, ancestry estimates of how closely related they are to African populations vary massively for each individual. Many people are much closer to "white" populations than any African population, due to the history of African Americans in North America. If you really mean race as a geographic proxy, the "black" label is simply confusing what you actually mean.
For what it's worth, I'm mixed as hell. European, Asian, Jewish, north african, and native american. I look white, though - and I am, in fact, majority European ancestry. Therefore in most studies (of anything race related), I would presumably be lumped in with white people. It's not a perfect "measure," but it's still the easiest proxy for geographic location of our ancestors that we have and on a population level it works just fine for studies.
Though I will say it's beyond argument that geographic ancestry has an effect on IQ on a statistical group level (the reasons for this are what's debated), and that IQ is the best measurement of G that we have.
It "is biased" to document human knowledge as accurately as possible. Is there something wrong with that?
Regardless, one can see this claim of inaccuracy repeated in these comments with no provided example of such. The saying goes "what is presented without evidence can be dismissed without evidence". It is therefore reasonable for a reader to conclude that the claim of inaccuracy can be dismissed as "bullshit", in the sense that the person making it cares not for its veracity.
"Anonymous surveys of intelligence experts reveal division: a 2016 survey found that about 49% attributed 50% or more of the Black-White gap to genetics, while over 80% attributed at least 20%; an earlier 1980s survey showed similar splits. These views are more common in private or anonymous contexts, contrasting with public statements from bodies like the APA that find no support for genetic explanations."
Hm, sure seems like Wikipedia should probably have a more balanced, nuanced discussion considering the experts are split at least 50/50.
Bringing up an opinion poll as a counterpoint makes it read like you're arguing that Wikipedia should focus less on fact and more on opinion. Of course, you're free to think what you wish, but I suspect that's where most disagree.
Genetics certainly don't explain all the differences in IQ. They very well might not explain the majority of the the difference. However, considering we know that intelligence is quite heritable along with various adoption and twin studies that have happened throughout the decades (along with simple freaking logic), we have a pretty good idea that it explains at least some of the difference. That "opinion poll," while not super-great because only some elected to reply, was a poll of experts in the fields that study this stuff, not random people.
A real unbiased article would mention that (and perhaps whatever counterarguments there are), not straight up do the encyclopedia equivalent of sticking their fingers in their ears and going "nah uh I can't hear you."
- this tends to approximate consensus.
- Wikipedia does care, and has a policy on this: https://en.wikipedia.org/wiki/Wikipedia:Scientific_consensus

Did I miss where you presented evidence that wikipedia is wrong? You seem to be taking an assumption you carry (race is related to IQ) and assuming everyone believes it's true as well, thus wikipedia is lying.
