The behavioral immune system and conservatism as predictors of disease-avoidant attitudes during the COVID-19...

The COVID-19 pandemic presents a unique opportunity to explore the relationships between the behavioral immune system (BIS), Political Ideology, and disease avoidant attitudes (e.g., attitudes toward vaccination and attitudes about COVID-19). The BIS (e.g., disgust) is believed to be the first line of defense against pathogens and has been linked to socially conservative values. Ironically, however, the BIS has also been associated with anti-vaccination attitudes. In the current study, American participants (N = 139) completed an online survey with self-report measures of the BIS (e.g., disgust sensitivity and perceived infectability), political ideology, COVID-19 attitudes, and anti-vaccination attitudes. Disgust sensitivity was positively correlated with anti-vaccination attitudes but not significantly correlated with attitudes toward COVID-19. Perceived infectability, however, was negatively correlated with anti-vaccination attitudes and positively correlated with anxiety and knowledge about COVID-19. Right-wing authoritarianism and support for Trump were negatively correlated with knowledge and anxiety about COVID-19 and positively correlated with anti-vaccination attitudes.
