I think you need to go back to my cockroach post and reread it.
Instead of focusing on your dumbass inference that I compare cockroaches with blacks, focus on what I said.
If we look at intelligence between two groups (in that case, two completely different species), we don’t have to know which gene does what to make an accurate inference.
I can state confidently that humans are more intelligent than cockroaches even if I don’t know which genes in humans are responsible for that difference. What I do is control for nurturing. I know that no amount of nurturing would get a cockroach up to a human level of intelligence.
Likewise, if I’m comparing two groups of humans, I don’t have to use as my standard the one you propose: Exactly which gene doing exactly what?
There is a much more reasonable standard. Recognize a pattern. Postulate genetic and nurturing reasons. Examine which explanation for differences seems the most persuasive.
For human populations–including race-based groups–there are consistent patterns. There are good reasons to postulate genetic differences. There are good ways to exclude nurturing variables. The most parsimonious explanation for the residual differences in the patterns and outcomes we observe is genes.
Moreover, genetic science is making rapid advances that identify those genes, and the research always pushes in the same general direction: Genes drive who we are. Clinging to the hope that we’ll find our neurobiological genes don’t cluster by race when all other genes do is beyond pitiful. It’s completely unrealistic.
It’s not as if the research seems to suggest that everyone has about the same genes and that those genes don’t drive differences. It’s always exactly the same direction: Hey; this gene controls this function and these variants have these disparate outcomes. So since we know that genes variants do cluster by race, the notion that those clusterings drive the disparate outcomes we see is not only a reasonable explanation, it’s the most likely explanation.
Even when we can’t name the gene.
But I think all of this is a bit over your ability to grasp, so you are just interested in the “Neener neener neener Pedant thinks blacks should be compared with cockroaches” approach to a rational discussion.
Idiot.
