Individual Differences in the Behavioral Immune System and the Emergence of Cultural Systems

Cultural variation may be evoked through the interaction between domain-specific psychological mechanisms and environmental conditions (Gangestad, Haselton, & Buss, 2006 ).

Description
Summary:Cultural variation may be evoked through the interaction between domain-specific psychological mechanisms and environmental conditions (Gangestad, Haselton, & Buss, 2006 ). One such constellation of mechanisms is the behavioral immune system, a cluster of psychological processes evolved to promote disease-avoidance ( Schaller, 2006 ). Previous research demonstrated that higher levels of both historic and contemporary pathogen prevalence are predictive of collectivism across geopolitical regions ( Fincher, Thornhill, Murray, & Schaller, 2008 ). Across two studies, we demonstrate that individual differences in behavioral immune system reactivity (e.g., disgust sensitivity, germ aversion) are associated with variable endorsement of a vertical collectivist cultural orientation and differential value priorities, which are indicative of cultural differences. These findings provide support at an individual level for the proposition of evoked culture.
