The review article "Thirty Years of Research on Race Differences in Cognitive Ability" by Rushton and Jensen was published in 2005.Richard Nisbett, another psychologist who had also commented at the time, later included an amplified version of his critique as part of the book Intelligence and How to Get It: Why Schools and Cultures Count (2009).Currently, there is no non-circumstantial evidence that these differences in test scores have a genetic component, although some researchers believe that the existing circumstantial evidence makes it at least plausible that hard evidence for a genetic component will eventually be found.The first test showing differences in IQ test results between different population groups in the US was the tests of United States Army recruits in World War I.In the 1920s, groups of eugenics lobbyists argued that this demonstrated that African-Americans and certain immigrant groups were of inferior intellect to Anglo-Saxon whites due to innate biological differences, using this as an argument for policies of racial segregation.

In his influential work, A Study of American Intelligence, psychologist Carl Brigham used the results of the Army tests to argue for a stricter immigration policy, limiting immigration to countries considered to belong to the "Nordic race".As the de-segregation of the American South gained traction in the 1950s, the debate about black intelligence resurfaced.Audrey Shuey, funded by Draper's Pioneer Fund, published a new analysis of Yerkes' tests, concluding that blacks really were of inferior intellect to whites.The concept of intelligence and the degree to which intelligence is measurable is a matter of debate.While there is some consensus about how to define intelligence, it is not universally accepted that it is something that can be unequivocally measured by a single figure.
