The problem of unwelcome epistemic company refers to the problem of encountering agreement with your beliefs from an unwelcome source, such as someone who is known to form unreliable beliefs or have values you reject. Blanchard (2023) and Levy (2023) argue that when we encounter unwelcome agreement, we may have reason to reduce our confidence in our matching beliefs. I argue that unwelcome epistemic company rarely provides reasons to reduce our confidence, and apparent successes at improving our beliefs using unwelcome (...) company are explained by extraneous factors. Seeing why unwelcome agents are rarely evidence our belief is false requires making a distinction between two kinds of agents who regularly form false beliefs: unreliable agents and anti-reliable agents. While unreliable agents are common, they are uninformative. While anti-reliable agents would be informative, they are incredibly rare. Unwelcome agents are also rarely evidence that we have formed our own beliefs via an unreliable process, unless we have independent evidence that we are relevantly similar to them. This is hard to obtain given that unwelcome agents, by definition, have values and methods of forming beliefs that we do not find appealing. Moreover, attempts to use unwelcome company to improve our beliefs are likely to make our beliefs worse off in a number of ways. I argue we should adopt a policy of ignoring unwelcome company, letting them have little impact on our confidence in our beliefs. (shrink)

This paper introduces three new concepts: epistemic health, epistemic immunity, and epistemic inoculation. Epistemic health is a measure of how well an entity (e.g. person, community, nation) is functioning with regard to various epistemic goods or ideals. It is constituted by many different factors (e.g. possessing true beliefs, being disposed to make reliable inferences), is improved or degraded by many different things (e.g. research funding, social trust), and many different kinds of inquiry are relevant to its study. Epistemic immunity is (...) the robustness with which an entity is resistant to performing certain kinds of epistemic activity, such as questioning certain ideas, believing certain sources, or making certain inferences. Epistemic inoculation occurs when social, political or cultural processes cause an entity to become immune to engaging in certain epistemic activities. After outlining each of these concepts, we close by considering some of the risks associated with attempts to improve others’ epistemic health. (shrink)

We carry out most of our epistemic projects as groups. Networks of individuals work together to identify questions, accumulate evidence, and settle on answers that lie beyond the ken of individual knowers. This is particularly important for controversial issues. And when it comes to ideologically contested issues, groups that are ideologically diverse in their membership are epistemically superior to groups that are ideologically homogenous. That’s because ideologically diverse groups are better at (a) identifying a representative sample of important questions, (b) (...) developing a wider range of potential answers, and (c) evaluating the evidence for and against each option. Awareness of this point produces a competence defeater for the relevant outputs of ideologically homogenous groups: they don’t deserve the high level of trust we often grant them. That, among other things, goes a long way towards justifying the public’s decreased trust in institutions like social networks, journalism, and universities. (shrink)
