On the Evolutionary Roots of the Social Sciences

Abstract

Purpose – The purpose of this chapter is to show that because the evolutionary roots of many kinds of phenotypic social phenomena can be partly traced to genotypic factors, it would be useful for social sciences to adopt a socio-biological research formula, which combines the impacts of genotypic and environmental explanatory factors.

Design/methodology/approach – The exclusion of evolutionary factors from social sciences and some previous studies using evolutionary factors is first reviewed, after which a socio-biological research formula (y=(a+b)+x) is introduced. It is hypothesized that national IQ as an important genotypic factor explains a significant part of the global variation in all kinds of phenotypic social phenomena. The hypothesis is tested and the use of the socio-biological research formula is illustrated by studies of democratization (ID-10) and human development (HDI-11).

Findings – The results of correlation analysis support the hypothesis on the evolutionary variable’s (national IQ) universal explanatory power. National IQ explains 33 percent of the variation in ID-10 and 68 percent of the variation in HDI-11. Environmental variables increase significantly the explained part of variation in a dependent variable in the case of ID-10 but less in the case of HDI-11.

Practical implications – Because it is evident that national IQ as an evolutionary variable explains a significant part of the variation in all kinds of phenotypic social phenomena, it would be sensible for social sciences to adopt the suggested socio-biological research formula based on the idea that intelligence constitutes an important common explanatory factor.

Originality/value – The suggested socio-biological research formula provides for the social sciences a common theoretical starting point to study many kinds of social problems.
