European Journal of Personality: Discussion on “The g-factor of international cognitive ability comparisons: the homogeneity of results in PISA, TIMSS, PIRLS and IQ-tests across nations”, by Heiner Rindermann

By Jüri Allik, Department of Psychology, University of Tartu, Estonia

Abstract
“Rindermann’s study provides the most comprehensive evidence so far that national scores of school assessment have systematic differences and the geographical distribution of these differences almost perfectly repeat the distribution of the mean national scores of intelligence. It is argued that without comparison with the random effects of statistical aggregation it is impossible to decide whether additional factors are needed to explain the strong association between national scores of school assessment and intelligence tests. The ignorance about real differences in mental abilities may become a source of social injustice because this does not allow natural inequalities to be arranged such that they are to the greatest benefit of the least advantageous.”
