The Politics of Vaccine Hesitancy: An Ideological Dual-Process Approach

Ideological convictions are known to shape attitudes and behavior in various life domains. Based on existing psychological analyses of political ideology, we use an ideological dual-process approach to explain people’s vaccine hesitancy, which distinguishes between authoritarian (right-wing authoritarianism [RWA]) and hierarchical (social dominance orientation [SDO]) facets of conservatism as potential antecedents of vaccination attitudes. In a large international study performed in Germany ( N = 1,210), Poland ( N = 1,209), and the United Kingdom ( N = 1,222), we tested the roles of SDO and RWA in predicting vaccination hesitancy, as well as cross-cultural universality of the pattern of relationships between political ideologies and attitudes toward vaccines. In all three countries, high SDO was associated with higher vaccine hesitancy, whereas high RWA was associated with lower vaccine hesitancy. These findings contribute to our understanding of the distinctive roles that these two facets of right-wing ideology might play in the domain of public health.
