I'd encourage you to resist that assumption. The article is interested in the shortcomings of race science, specifically the science of genetics as it applies to racial differences. The author isn't denying that there are differences in average intelligence between races; he's simply saying that there is no empirical evidence that the root cause of those differences is genetic. A scientific perspective that privileges empiricism shouldn't jump to certain conclusions based on speculative connections between general racial homogeneity and statistical commonalities. The proper response should be that while genetics could explain these differences, there is no way to empirically verify such connections. Therefore, it's irresponsible to promote such a theory based on current studies/research.
The studies that have been cited as supporting race science have also been subject to mild, if not gross, misinterpretation. I think that's the point of the article.
I know you want to wave this away as "virtue signaling"; but my impression is that it's impossible to make an argument even comparable to this without you criticizing it as virtue-signaling, which is why I find your comments suspect.
Well I'm not saying you are virtue signaling here, and there is certainly evidence for IQ gains from things like better nutrition, stable home environment, and quality education. But the author likely is signlaing(I mean, he is a "journalist" - his job is almost entirely signaling), especially considering he wrote a book on the topic. Since the sort of "Race science" he's probably familiar with from his book writing about is about 100 years out of date, the following is probably explained by that:
"Dullness" would be low average. So he's not incorrect:

WAIS uses the same intervals as Terman.
Terman helped develop the Stanford-Binet revision of the first IQ test back in 1916, and the use of "Dullness" is fairly obsolete. The current version of the S-B IQ test uses "Low Average" for 80-89.
Again, this is not true Dak.
The Similarities test assesses abstract verbal reasoning yes; but the comprehension portion assesses the "ability to express abstract social conventions," and matrix reasoning assesses "nonverbal abstract problem-solving." The verbal and perceptual categories both test for abstract logic. Memory and processing don't, but these also can only be tested via the application of abstractions. The test is very much invested in abstract thinking.
The memory test is literally just repeating series of numbers back to the testor, and the processing speed tests involve things like crossing out items the test says to, and these items are mixed in sporadically with other items. Vocabulary is testing memory of and/or exposure to words. Information tests the same thing but on random factoids in basic science, history, etc rather than words. Calling these "abstract" is fairly tortured imo. I don't have items from the Comprehension test memorized, but I obviously couldn't share them anyway if I did. However, Comprehension is not even a core test, but rather available as a substitute or for further testing if one is concerned about performance on certain other tests. Matrix Reasoning does test abstract reasoning, but doing poorly on that test can't be blamed on poor schooling or something. We don't have classes on shape series afaik. Still, we are talking about 2 tests out of a total of 10 if we include both verbal and symbol abstraction. 1/5 of the total test, not "all of it", which is what the author asserted:
abstract logic, which is the sliver of intelligence that IQ tests measure.
