Pathogenic diseases impose selection pressures on the social behaviour of host populations. In humans(Homo sapiens), many psychological phenomena appear to serve an antipathogen defence function. Onebroad implication is the existence of cross-cultural differences in human cognition and behaviourcontingent upon the relative presence of pathogens in the local ecology. We focus specifically on onefundamental cultural variable: differences in individualistic versus collectivist values. We suggest thatspecific behavioural manifestations of collectivism (e.g. ethnocentrism, conformity) can inhibit thetransmission of pathogens; and so we hypothesize that collectivism (compared with individualism) willmore often characterize cultures in regions that have historically had higher prevalence of pathogens.Drawing on epidemiological data and the findings of worldwide cross-national surveys of individualism/collectivism, our results support this hypothesis: the regional prevalence of pathogens has astrong positive correlation with cultural indicators of collectivism and a strong negative correlation withindividualism. The correlations remain significant even when controlling for potential confoundingvariables. These results help to explain the origin of a paradigmatic cross-cultural difference,and reveal previously undocumented consequences of pathogenic diseases on the variable nature ofhuman societies.
