I remember it read as if it were written by a Stormfronter.

Are you sure? I skimmed through the article and it still takes the extremely Liberal position that genes don't matter or IQ doesn't exist. Like this,

There is a paradox from IQ studies in Africa that has yet to be resolved. Europeans with an IQ of 70 are considered mentally retarded. However, the Africans found to have an IQ of 70 were perfectly normal with the apparent ability to function normally in their social environment. This has led to questions of the validity of these IQ tests[38][39] A 1995 study published in the Journal of Nutrition concluded that IQ scores of children in the West Indies are depressed to some extent by environmental conditions, such as macronutrient and micronutrient deficiencies[40][41] and even blood lead levels.[42] The study suggested the existence of broader links between malnutrition and IQ levels across the developing world as a whole.[43] Southern Italian immigrants in the US scored below 80 on IQ tests in the early 20th century[44] but had improved their average scores in later decades, bringing the validity of theories of genetically fixed and racially based IQ into further question.

And in regards to the Southern Italians, I recall the issue is the tests were conducted in English, to which the immigrants took some time to adjust. However, Blacks (who have obviously been in America longer since the 1600s) were raised under English and still did the worst of any group. So obviously there's a genetic component to this.
