Context: The CDC's ability to respond to communicable disease threats has recently met significant political and legal opposition. The authors unpack the influence of political ideology on support for CDC authority, and they experimentally assess whether highlighting ideology's role in responding to health threats might bolster CDC support.
Methods: The authors fielded a demographically representative online survey experiment to 5,483 US adults. They assessed the sociopolitical correlates of CDC attitudes via multivariate regression analyses limited to a study-wide treatment group. Additionally, they tested the effectiveness of their experimental treatments via multivariate models that interact indicators of stimulus exposure with political ideology.
Findings: Although most Americans support the CDC's role in responding to health crises, self-identified conservatives are significantly less likely to do so. This effect holds when accounting for respondents' limited government and anti-expert attitudes, which the authors replicated in nationally representative data. Encouragingly, though, emphasizing the CDC's role in combating the spread of COVID-19 is associated with significantly stronger levels of support on the ideological right.
Conclusions: Efforts to communicate the CDC's importance in responding to health threats can help bridge existing ideological divides and might create an incentive for policy makers to codify the agency's regulatory powers.
