QuoteTo compute the intelligence of nations, measured IQ and achievement test results are used. While these are not perfect measurements of intelligence, IQ scores are predictive of socially important outcomes and show low levels of bias between groups (Jensen, 1980), in contrast to personality measurements which are confounded by reference group effects (Credé et al., 2010).
Multiple sources of data were consulted, including psychometric estimates (Becker unweighted, Becker sample-weighted, Becker quality-weighted), scholastic estimates (World Bank test scores, basic skills dataset, PISA 2022 results, Becker scholastic estimates, Rindermann scholastic estimates), and composite estimates (Lynn & Vanhanen 2012, Lynn & Vanhanen 2002, Becker composite, Rindermann composite). If a dataset included geographic imputations, the imputations were removed.
The average IQ of the world is 85.3 when weighted by population size.
