Rindermann correlated the national averages of several student assessment studies and ‘national IQ’ estimates and proposes that these variables are all indicators of a common cognitive ability at the macro-social level, which he denotes the national g-factor. We argue that Rindermann oversimplifies issues of individual differences and applies inappropriate statistical analyses. Therefore, we refute his conclusions.
