Dual Evolutionary Foundations of Political Ideology Predict Divergent Responses to COVID-19

Political conservatives' opposition to COVID-19 restrictions is puzzling given the well-documented links between conservatism and conformity, threat sensitivity, and pathogen aversion. We propose a resolution based on the Dual Foundations Theory of ideology, which holds that ideology comprises two dimensions, one reflecting trade-offs between threat-driven conformity and individualism, and another reflecting trade-offs between empathy-driven cooperation and competition. We test predictions derived from this theory in a UK sample using individuals' responses to COVID-19 and widely-used measures of the two dimensions – ‘right-wing authoritarianism’ (RWA) and ‘social dominance orientation’ (SDO), respectively. Consistent with our predictions, we show that RWA, but not SDO, increased following the pandemic and that high-RWA conservatives do display more concerned, conformist, pro-lockdown attitudes, while high-SDO conservatives display less empathic, cooperative attitudes and are anti-lockdown. This helps explain paradoxical prior results and highlights how a focus on unidimensional ideology can mask divergent motives across the ideological landscape.
