Examining the Left-Right Divide through the Lens of a Global Crisis: Ideological Differences and Their Implications for Responses to the COVID-19 Pandemic
The COVID-19 disease pandemic is one of the most pressing global health issues of our time. Nevertheless, responses to the pandemic exhibit a stark ideological divide, with political conservatives (versus liberals/progressives) expressing less concern about the virus and less behavioral compliance with efforts to combat it. Drawing from decades of research on the psychological underpinnings of ideology, in four studies (total N = 4,441) we examine the factors that contribute to the ideological gap in pandemic response—across domains including personality (e.g., empathic concern), attitudes (e.g., trust in science), information (e.g., COVID-19 knowledge), vulnerability (e.g., preexisting medical conditions), demographics (e.g., education, income) and environment (e.g., local COVID-19 infection rates). This work provides insight into the most proximal drivers of this ideological divide, and also helps fill a longstanding theoretical and empirical gap regarding how these various ideological differences shape responses to complex real-world sociopolitical events. Among our key findings are the central role of attitude- and belief-related factors (e.g., trust in science and trust in Trump)—and the relatively weak influence of more domain-general personality factors (e.g., empathic concern, disgust sensitivity). We conclude by considering possible explanations for these findings and their broader implications for our understanding of political ideology.
