Can History of Parasitic Diseases Increase Social Conservatism? Testing Behavioural Immune System Theory

Summary/Abstract: Aim. Using available data from previously published study the hypothesis that individuals with broader disease history are more conservative than those, who were infected less often in the past was tested. Methods. Publicly available database containing data regarding perceived vulnerability to disease, social conservatism and participant’s history of parasitic diseases was accessed. History of parasitic diseases, self-declared, consisted of nine commonly occurring in tropical areas parasitic diseases. In the study 9409 cases from 43 countries were analysed. Results. When controlling for participant’s age, sex, education level, wealth and perceived infectability, it was found, that broader disease history was a significant predictor of social conservatism. Additionally, it was found, that wealth and age were negative predictors of social conservatism. All obtained effects were relatively small, but significant. The results are discussed in the light of previous research. Conclusions. Individuals, who were in the past infected with parasitic diseases more often, were observed to be more conservative than people, who had suffered from these diseases less often.
