When Citizens Don’t Know Whom to Believe: Failures in the Testimonial Exchange of Political Information and Its Implications for Epistemic Democracy

This cumulative dissertation comprises four articles addressing questions related to the so-called ‘epistemic crisis of democracy’, in particular regarding widespread contestation of expertise and denial of scientific consensus. These phenomena are worrisome for (deliberative) epistemic democrats, as they can undermine the epistemic merits of democracy. These worries are typically only understood in veristic consequentialist terms, or as instrumental concerns for democracy, leading to suboptimal outcomes. But this picture, I argue, is incomplete. This dissertation utilizes tools from the social epistemology of testimony to analyse the epistemic crisis from a novel perspective and locates issues that have so far remained underexplored. The following research question guides this inquiry: How does the contemporary (online) epistemic environment affect testimonial exchange of political information, and what are the implications of these changes for epistemic democracy? Article 1-3 provide a deeper understanding of the epistemic challenges citizens face when gathering political information. Article 1, ‘Public Credibility Dysfunction and Unreliable, Unsafe Political Beliefs’, discusses how our (online) epistemic environment thwarts citizens ability to make apt credibility appraisals. It further argues that the widespread failure of credibility monitoring and policing, what I call ‘public credibility dysfunction’, not only explains widespread ignorance and increasing false beliefs, but also affects the epistemic status of our true beliefs. Article 2 and 3 illustrate how public credibility dysfunction frustrates public uptake of expert-testimony. Article 2, ‘Echo Chambers, Epistemic Injustice and Anti-Intellectualism’, discusses conceptual links between testimonial injustice and echo chambers, and how the latter can cause dismissal of expert-testimony on politically sensitive topics (e.g. vaccination). Article 3, ‘Testimonial Injustice Without Social Injustice: Rejection of Expert-Testimony as Morally Significant Epistemic Negligence’, builds on these insights and provides a broader account of testimonial injustice, that acknowledges how (epistemically) privileged groups (i.e. experts) can be treated unjustly in testimonial exchange. Article 4 ‘Procedural Epistemic Democracy and Virtue-based Citizen Competence’, argues that procedural views are not irrelevant for discussions of challenges to epistemic democracy. It provides a broader understanding of citizen competence that includes virtue-based epistemic responsibilities, and argues that procedural accounts of epistemic democracy can generate such responsibilities by employing a procedural account of social epistemology.
