Abstract

This paper introduces the special issue of Diametros devoted to discussing “Expertise, Disagreement, and Trust in Vaccine Science and Policy. The Importance of Transparency in a World of Experts” by Alberto Giubilini, Rachel Gur-Arie, and Euzebiusz Jamrozik. In their article, Giubilini et al. argue that expert transparency—particularly regarding disagreements among experts—is ethically crucial for securing public trust in vaccine policy. Several contributors to this issue expand upon that claim. For example, Maciej Macuga proposes that transparency is necessary to make coercive vaccination policies morally legitimate, and Lucie White interprets the core disagreement surrounding vaccine recommendations as a divergence in underlying values. Other authors challenge aspects of Giubilini et al.’s position: Udo Schüklenk and Ben Almassi caution that greater transparency may not bolster trust or improve vaccine uptake, while Ezio Di Nucci presents an analytical argument showing that a purely epistemic notion of expertise leads to paradoxical conclusions—namely, that experts should care neither about trustworthiness, nor trust. Jamie Watson emphasizes that it is the reliable process of producing scientific knowledge that grounds expert trustworthiness. Finally, Elena Popa and Richard Matthews argue that redistributions of power, both in society at large and within expert communities, are necessary to foster genuine trust.
