More recent research attempting to identify genetic loci associated with individual-level differences in IQ has yielded promising results, which led the editorial board of Nature to issue a statement differentiating this research from the "racist" pseudoscience which it acknowledged has dogged intelligence research since its inception.

This paper suggested that the average IQ score of Ashkenazi Jews fall in a range of 108–115 under some studies, which would be significantly higher than that of any other ethnic group in the world. [15] [17] [18] The paper received widespread coverage in media. [19] [20] [21] The paper attracted significant criticism and controversy.
David Marks (2010) argues that differences in average IQ scores between national groups and across time periods can be fully accounted for by differences in literacy levels, and that "IQ distributions will converge if opportunities are equalized for different population groups to achieve the same high level of literacy skills."

A section in IQ and human intelligence (1998) by Nicholas Mackintosh discussed ethnic groups and Race and intelligence: separating science from myth (2002) edited by Jefferson Fish presented further commentary on The Bell Curve by anthropologists, psychologists, sociologists, historians, biologists and statisticians.

Stressing the similarity of average IQ scores across racial groups in the Eyferth study, James Flynn, Richard E. Nisbett, Nathan Brody, and others have interpreted it as supporting the notion that IQ differences between whites and blacks observed in many other studies are mostly or wholly cultural or environmental in origin.

Cognitive test scores predict educational performance better than they predict any other outcome, and cognitive testing is pervasive in academics [citation needed].Central policy issues concern the proper role of testing in assessing educational quality and in college admission; efforts to characterize and close the educational achievement gap between racial and socioeconomic groups in the US ...
The IQ figures are based on 3 different studies for 17 nations, two studies for 30 nations, and one study for 34 nations. There were actual tests for IQ in the case of 81 countries out of the 185 countries studied. For 104 nations there were no IQ studies at all and IQ was estimated based on the average IQ of surrounding nations. [2]
The debate concerns possible explanations of group differences encountered in the study of race and intelligence. Since the beginning of IQ testing around the time of World War I there have been observed differences between average scores of different population groups, though these differences have fluctuated and in many cases steadily ...
