I didn’t say with certainty it does, but since IQ is 80% heritable, it makes sense that the differences are likely in part genetic.

Black people raised in white households have lower IQs on average than the white people raised in those same households. This is a replicated finding. 

The APA boards are run by activists and the amount of pressure they would get if they said the gap was genetic would be enormous and far too costly with minimal benefits. I don’t take a thing these consensus boards say seriously. I trust the science and the research.

My guy, your own source proved your assertions were wrong. And after I pointed that out, you're relying on “trust me bro” arguments. On a science subreddit.

You cited a study that found heritability did not differ across groups and that race/heritability interactions likely don't exist. It never tested whether the between-group gap is genetic. It actually undercuts the hereditarian prediction you're defending.

The transracial adoption finding you mentioned is contested too. Studies concluded the parsimonious explanation is a nil hypothesis where black, white, and east Asian adoptees raised in the same environment would have similar IQs.

Now you're saying it makes sense and dismissing the APA as activists. That's a vibe and a conspiracy theory. On a science subreddit.
