Citizen Science in News Media: Boundary Mediation of Public Participation in Health Expertise

In this article, I examine how scientific boundary work describes or represents citizen science as credible forms of expertise. Citizen science is an ambiguous concept, and I leverage that ambiguity to examine citizen science as a proxy for nonprofessional or noninstitutional scientific practices more generally. I argue that media representations of citizen science perform boundary work through different articulations of institutional "buy-in" to the legitimacy or credibility of citizen science. Using a discourse analysis of mainstream news media, I trace three framings of citizen science's relationship to institutional networks, which I describe as subservient to, corrective to, and exceeding the norms of institutional expertise. I find that the perspectives of professional, credentialed scientists dominate public discourse concerning citizen science and perform different adjudications of how citizen science contributes to networks of expertise. By focusing on citizen science concerning human health and medicine, I additionally show how mainstream framings of citizen science engage with overlapping media representations of personal health responsibility and patient empowerment. I suggest that representations of citizen science as a form of "missing expertise" can conflict with portrayals of citizen science as "going too far" in the pursuit of treatments or interventions.
