So let me just come out and ask: on the matter of race and intellect, what is it you believe? Can you be specific about those beliefs in the context of American "white", black, and Asian people?
I do strongly hold the position that a genetic explanation, should one exist, says absolutely nada about policy, "supremacy," how we should treat each other, or really anything else. I also strongly believe that a good faith inquiry into this question (and acceptance of whatever the science reveals) is a pursuit orthogonal to "white supremacy. This is so obvious to me that I feel silly even rebutting it.
Again, I'm not advancing one particular explanation for group differences. I'm opposing your treatment of the implications of one of those possible explanations.
Further, as I stated elsewhere in this thread, the statement "white people are smarter than black people" as a summary of population differences is statistically and biologically illiterate. This way of talking about these issues is unscientific and obfuscatory and it has no place in serious conversations on this topic.
† My personal opinion, as a non-expert, is that the differences are probably explained by a complicated mix of factors, but that genetics likely play some role. If this seems wishy-washy, it's because it is. I'm including this footnote only to avoid the accusation that I'm dodging your question. My opinions here aren't worth much. Frankly, I doubt yours are, either, unless you've got a second career you haven't mentioned in your profile.
I no longer believe that's possible.
Edit: Just to make this explicit: I don't have any eccentric or unorthodox views about the differences between "races." I haven't advanced any such views here, nor do I hold them privately. tptacek's implication, of course -- and this happens in every single one of these conversations -- is that I'm concealing some detestable opinion about race. That's why there's always this persistent pleading to clarify what you actually believe. I've stated quite clearly what it is that I believe. No more or less. If I haven't been clear, then we'll just have to attribute that to my failings as a communicator and call it a day.
Fact: IQ results differ by race, even though 'races' are a badly-defined concept. Fact: Socioeconomic factors are a lot of this. Postulation: There might maybe be a genetic factor somewhere. Assertion: This doesn't justify treating people differently by race.
What is unclear? What do you object to? You seem to find the idea that there might be any, miniscule genetic factor to intelligence that is more or less common in a specific 'race' as equal to white supremacy. Am I misreading you?
(And note I didn't say anything about which way genetic factors might go. If they exist they might be opposite the socioeconomic factors, who knows.)
Are you denying that there are differences in the genes controlling hair color between different racial groups? Or the frequency of something like lactose intolerance?
"Races" are badly defined, with shifting definitions and fuzzy borders and many different ways of grouping the same people. The idea of categorizing people into a handful of "races" rather than looking at hundreds of intersecting ancestries mixing together is dumb. But there is still a correlation between the two concepts. If you can find a gene that correlates with an ancestry (which you can do), then you've also found a gene that has a weaker correlation with "race".
And because there are thousands of genes that will correlate slightly with race, it's possible that one affects intelligence in some manner. It's not my problem if that's true. I'm confident there are no practically significant differences there. But that doesn't mean there isn't some .002% difference in median intelligence between groups that's caused by genes. It's bullheaded to ignore the possibility just because some awful racist will use it as "evidence" of their superiority. If they can't find out-of-context factoids to abuse they'll make things up anyway.
Some people argue that this is a good thing to do, but if you do this you can't complain about the phrase "virtue signaling," as someone prioritizing virtue over accuracy.
