Do Citizens Judge Health Experts Through a Partisan Lens? Evidence from a Factorial Survey Experiment

Abstract

AbstractScholars have claimed that right‐wing citizens are more skeptical about experts than left‐wing citizens. This article, however, argues that depending on their party affiliation, citizens prefer certain kinds of expertise over others. I confronted Swiss adults (N = 2,465) with individual risk advice on either flu vaccination or colorectal cancer screening. The quote varied regarding the expert providing the advice (e.g., academic, administration, or corporation) and the degree of policy advocacy. The citizens then assessed the experts' credibility and their own behavioral intention (e.g., get a flu shot). Citizens across the political spectrum are more likely to positively evaluate experts who represent institutions aligned with their beliefs. Moreover, right‐wing citizens are more skeptical about experts who advocate for specific policies than their left‐wing counterparts. This study underscores the need for a better understanding of how partisanship affects expert perceptions to manage health policy problems and other science‐based issues.
