Many social media platforms enable (nearly) anyone to post (nearly) anything. One clear downside of this permissiveness is that many people appear bad at determining who to trust online. Hacks, quacks, climate change deniers, vaccine skeptics, and election deniers have all gained massive followings in these free markets of ideas, and many of their followers seem to genuinely trust them. At the same time, there are many cases in which people seem to reliably determine who to trust online. Consider, for (...) example, Do It Yourself (DIY) content about how to play guitar, bake, fix one’s plumbing, or repair one’s car. For these topics, those who have the largest accounts and the most popular content typically possess significant expertise. That is, social media users seem to reliably pick out DIY experts. We thus have a puzzle: why are social media users seemingly competent at identifying DIY experts, but not climate science or vaccine experts? In what follows, we solve this puzzle. We begin by identifying a novel wisdom of the crowds phenomenon: specifically we argue that the crowd (in combination with social media search and recommendation algorithms) reliably picks out DIY experts and serves as a credentialing institution for DIY content. Next, we argue that (a) there are five epistemic factors that determine whether the crowd can succeed at recognizing experts on social media platforms, and (b) while many of those factors are satisfied to a sufficiently high degree by DIY content, they are mostly lacking for content about climate change or vaccines.

I will clarify when and how a tension arises between epistemic environmentalism (a new focus on assessing and improving the epistemic environment) and respect for epistemic autonomy (allowing, empowering, and requiring people to each govern their own beliefs). Using the example of participatory conceptual engineering (improving the linguistic environment through rational discussion with broad participation), I will also identify an option for avoiding the tension—namely, participatory environmentalism. This means a new focus on how people can each contribute to improving the (...) shared epistemic environment through rational deliberation and thereby govern their own beliefs that are shaped by that environment.

Epistemic bystanding occurs when an agent has all the competences, knowledge and opportunity to prevent another person from forming a false or risky belief, but does not prevent the belief formation. I provide a definition of an epistemic bystander and explain the mechanism that makes someone an epistemic bystander. I argue that the phenomenon is genuinely epistemic and not merely linguistic. Moreover, I propose an account of the mechanism of epistemic bystanding building on Ishani Maitra’s notion of licensing. An epistemic (...) bystander licenses a risky belief-forming process in another person and thereby performs a blameworthy epistemic action. This form of licensing explains the distinctive wrong of being an epistemic bystander. (shrink)

I argue that the concept of an epistemic interface is a useful one to add to the epistemic ecology toolkit in order to enrich our investigations concerning the complex epistemic phenomena arising on social media. An epistemic interface is defined as any informational interface (be it technical, human or institutional) that facilitates the transfer of epistemic goods from one epistemic environment to its outside, be that another epistemic environment or a person. When assessing the kinds of epistemic environments emerging on (...) social media platforms, we should not only look at their epistemic health or hostility as environments, but also look at how these environments interact with each other, at their interfacing. I show that several epistemic problems specific to social media such as epistemic bubbles, echo chambers and epistemic flooding can be understood also in terms of faulty epistemic interfacing, which adds a layer of complexity to the discussion. The paper proposes two criteria for healthy epistemic interfacing: preserving the flourishing of epistemic agents, and preserving in some form the value of epistemic outcomes as these cross the environment to the outside world. These criteria should give rise to specific norms and design requirements for healthy interfacing, but such norms will need more empirical work before these get formulated. (shrink)
