Abstract

Purpose – The purpose of this study is to explore to what extent global disparities in the wealth and poverty of nations can be explained by the evolved human diversity measured by the average intelligence of nations (national IQ).

Design/methodology/approach – It is hypothesized that nations with a higher average intelligence are able to produce better living conditions for their members than nations with a lower average intelligence. The hypothesis is tested by empirical evidence of national IQs measuring the average intelligence of nations and by indicators of per capita income, poverty, and human development measuring the wealth of nations from different perspectives. The study covers 187 contemporary countries.

Findings – The results of correlation analysis support the hypothesis. The correlation between national IQ and per capita income is 0.506, between national IQ and Population below $2 a day % it is −0.733, and between national IQ and human development it is 0.830. Regression analysis was used to illustrate the relationship between national IQ and income and human development at the level of single countries.

Practical implications – Because significant parts of global disparities in the wealth and poverty of nations can be traced to evolved human diversity measured by national IQ, human chances to remove or even to decrease those disparities are quite limited. We should learn to accept the inevitable social consequences of the evolved human diversity.

Originality/value – This study provides for social scientists a new perspective to explore the problems of global inequalities in human conditions.
