In philosophical work on the ethics of conversational exchange, much has been written regarding the speaker side—i.e., on the rights and duties we have as speakers. This paper explores the relatively neglected topic of the duties pertaining to listeners’ side of the exchange. Following W.K. Clifford, we argue that it’s fruitful to think of our epistemic resources as common property. Furthermore, listeners have a key role in maintaining and improving these resources, perhaps a more important role than speakers. We develop (...) this idea by drawing from Hugo Mercier and Dan Sperber’s “interactionist” picture of reason, which suggests that reasoning is essentially dialogical and relies on the epistemic vigilance of listeners. The paper defends an imperfect, prima facie duty to listen, one that is sufficiently strong to place substantial demands on individuals, but not so overly demanding as to be implausible. (shrink)

People report believing weird things: that the Earth is flat, that senior Democrats are subjecting kidnapped children to abuse, and so on. How can people possibly believe things like this? Some philosophers have recently argued for a surprising answer: people don’t believe these things at all. Rather, they mistake their imaginings for beliefs. They are shmelievers, not believers. In this paper, I consider the prospects for this kind of explanation. I argue that some belief reports are simply insincere, and that (...) much of the evidence for shmeliefs can be explained by the content of the beliefs reported, rather than by the attitude people take to them. But some reported beliefs are good candidates for being shmeliefs. I consider how shmeliefs are acquired and sustained, and why they might be harmful despite not being seriously believed. (shrink)

I respond to comments from Mark Bowker, Jessica Keiser, and Eliot Michaelson on my book, Talking About. The response clarifies my stance on the nature of reference, conflicting intentions, and the sense in which language may have proper functions.

Beliefs can be resistant to evidence. Nonetheless, the orthodox view in epistemology analyzes beliefs as evidence-responsive attitudes. I address this tension by deploying analytical tools on capacities and masking to show that the cognitive science of evidence-resistance supports rather than undermines the orthodox view. In doing so, I argue for the claim that belief requires the capacity for evidence-responsiveness. More precisely, if a subject believes that p, then they have the capacity to rationally respond to evidence bearing on p. Because (...) capacities for evidence-responsiveness are fallible and may be masked, beliefs can be held in the face of counter-evidence. Indeed, I will argue that our best science of belief supports the claim that evidence-resistant beliefs result from masks on evidence-responsiveness capacities. This account of belief not only allows for resistance to evidence, but provides us with a framework for describing and explaining actual cases of evidence-resistance. (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)

Hostile epistemology is the study of how environmental features exploit our cognitive vulnerabilities. I am particularly interested in those vulnerabilities arise from the basic character of our epistemic lives. We are finite beings with limited cognitive resources, perpetually forced to reasoning a rush. I focus on two sources of unavoidable vulnerability. First, we need to use cognitive shortcuts and heuristics to manage our limited time and attention. But hostile forces can always game the gap between the heuristic and the ideal. (...) Second, we need to trust others, and trust makes us vulnerable. In particular, we need to trust experts whose expertise lies beyond our individual ability to vet. So we must rely on various imperfect signals and proxies, like institutional affiliation, to manage our trust. We are forced to use these imperfect and exploitable forms of reasoning, in order to cope with a cognitively overwhelming world. I present the hostile epistemology framework as a counterbalance to vice epistemology, which tends to locate responsibility for bad beliefs in the character of the believer. I draw two conclusions from my analysis. First: suppose we accept that that only communities and institutions can know about the world. This deeply social approach doesn’t solve the problem of expert identification. The individual still faces a problem: given their incomplete understanding, how should the individual pick which group to trust? Second: we might have hoped to get some kind of static picture of the right principles of reasoning — but hostile epistemology presents a different picture. We have to use risky heuristics and shortcuts, which hostile forces can game and exploit. We can respond by shifting to a different set of heuristics, but this simply shifts the location of our vulnerabilities. These new heuristics are also exploitable. There is no end to this, only a constant struggle to adapt. Limited beings in a hostile epistemic environment are locked in an unending epistemic arms race. (shrink)

This paper argues for the existence of a certain type of defeater for one’s belief that P—the presence of social incentives not to share evidence against P. Such pressure makes it relatively likely that there is unpossessed evidence that would provide defeaters for P because it makes it likely that the evidence we have is a lopsided subset. This offers, I suggest, a rational reconstruction of a core strand of argument in Mill’s On Liberty. A consequence of the argument is (...) that on morally and politically laden issues in particular, a high degree of doxastic openness might be appropriate. (shrink)

Posts on social media platforms like Twitter are sometimes the products of deceptively designed bots. These bots can cause obvious epistemic problems, such as tricking human users into believing the contents of misleading posts. However, less-considered epistemic problems involve false bot judgements where a human user mistakes another human user’s post for a bot-post, or where a human user mistakenly believes that bots are the primary vehicles for tokening certain content on social media. This paper takes up three questions concerning (...) false bot judgements: what exactly are their associated epistemic harms, just how harmful are they, and what should we do about them? (shrink)

Conspiracy theories are spreading faster than ever and pose a real danger to our societies. It is natural to accuse the consumers of conspiracy theories of irrationality – that they are either not looking at or appropriately sensitive to all the available evidence. In this paper, I attempt to determine if we can make sense of this general idea. I argue that we cannot: conspiracy theories do not spread because the people who believe them are irrational – at least, not (...) necessarily so. In addition, I explore some alternative strategies for responding to the problem of the spread of conspiracy theories. I argue that in addition to confrontational strategies such as social shaming, we need more constructive programs of community activism to battle the spread of conspiracy theories. (shrink)

Many pseudosciences, conspiracy theories and other unfounded belief systems have a self‐sealing nature, being equipped with defence mechanisms and immunizing strategies that protect them against counterevidence and criticism. In this article, we discuss the existence of ‘epistemic black holes’, belief systems which posit intelligent agents that are deliberately evading detection and thus sabotaging any investigation into their existence. These belief systems have the remarkable feature that they predict an absence of evidence in their favour, and even the discovery of counterevidence. (...) The most obvious instances of such epistemic black holes are unfounded conspiracy theories, but examples crop up in other domains as well. We outline the development and cultural evolution of epistemic black holes, drawing from a number of case studies. Most importantly, because of their self‐sealing character and resilience to counterevidence, epistemic black holes suffer from a recurring problem of arbitrariness and proliferating alternatives. Shedding light on how epistemic black holes function can help to inoculate people against their enduring allure. (shrink)

Following Cass Sunstein's popular treatment of the concept, echo chambers are often defined as environments which exclude contrary opinions through omission. C. Thi Nguyen contests the popular usage and defines echo chambers in terms of in-group trust and out-group distrust. In this paper, I argue for a more comprehensive treatment. While both exclusion by omission and out-group distrust help sustain echo chambers, neither defines the phenomenon. I develop a social network model of echo chambers which focuses on the role of (...) belief-reinforcing echoes. First, I argue that the model allows us to incorporate Nguyen's main point about distrust without construing other commentators as deeply mistaken about the nature of echo chambers. Second, I use the model to develop an account of collaborative resistance and use it to clarify the role echo chambers play in spreading misinformation. (shrink)

What is the value of intellectual playfulness? Traditional characterizations of the ideal thinker often leave out playfulness; the ideal inquirer is supposed to be sober, careful, and conscientiousness. But elsewhere we find another ideal: the laughing sage, the playful thinker. These are models of intellectual playfulness. Intellectual playfulness, I suggest, is the disposition to try out alternate belief systems for fun – to try on radically different perspectives for the sheer pleasure of it. But what would the cog-nitive value be (...) of such playfulness? I suggest that intellectual playfulness function as, at the very least, a kind of intellectual insurance policy against epistemic traps. An epistemic trap is a belief system that re-directs good-faith inquiry to bad results. Am epistemic trap manipulates background beliefs to fend off contrary evidence. For example, a conspiracy theory might include a set of beliefs about how the mainstream media has been taken over by some vicious cabal. Normal epistemic attempts will be captured by a well-wrought epistemic trap, because normal attempts at inquiry are guided by these background beliefs -- which set what counts as a plausible path to explore, and what is implausible or beyond the pale. And a clever epistemic trap will manipulate those background beliefs for ill effect. Intellectual playfulness, on the other hand, isn’t motivated by an epistemic interest in the truth, but in the sheer pleasure of intellectual exploration. Since intellectual playfulness isn’t oriented towards the truth, it won’t be constrained by an agent’s background beliefs – it won’t, for example, prefer to investigate apparently more plausible pathways. Intellectual playfulness offers an opportunity to escape from epistemic traps. But intellectual playfulness has its own limitations. It will only drive us to explore belief systems when that exploration is fun. What we need is an array of differently-motivated exploratory tendencies – empathy, curiosity, playfulness – each of which will each cover for the others’ limitations. (shrink)

I argue that introspection recruits the same mental mechanism as that which is required for the production of ordinary speech acts. In introspection, in effect, we intentionally tell ourselves that we are in some mental state, aiming thereby to produce belief about that state in ourselves. On one popular view of speech acts, however, this is precisely what speakers do when speaking to others. On this basis, I argue that every bias discovered by social epistemology applies to introspection and other (...) forms of self-directed representation. If so, it becomes unclear in what sense social epistemology is social. (shrink)

Although research on epistemic injustice has focused on the effects of prejudice in epistemic exchanges, the account of prejudice that emerges in Fricker’s (2007) view is not completely clear. In particular, I claim that the epistemic role of prejudice in the structure of testimonial justification is still in need of a satisfactory explanation. What special epistemic power does prejudice exercise that prevents the speaker’s words from constituting evidence for the hearer’s belief? By clarifying this point, it will be possible to (...) address two more general issues concerning the nature of prejudice: its resistance to counterevidence and the steps involved in overcoming prejudice. I propose a hinge account of prejudice, based on the recent perspective of hinge epistemology, to help clarify these aspects. According to the hinge account, prejudices share a fundamental feature with hinges: they work as norms of evidential significance, and as such, they determine what can and cannot count as evidence for belief.

The purpose of this paper is two-fold: to provide a philosophical justification for the counterintuitive attitude that Judaism seems to have towards proselytism; and to extend the case so as to create a general argument, applicable to all religions, against many forms of proselytism.

This article develops a new approach for theorizing about hermeneutical injustice. According to a dominant view, hermeneutical injustice results from a hermeneutical gap: one lacks the conceptual tools needed to make sense of, or to communicate, important social experience, where this lack is a result of an injustice in the background social methods used to determine hermeneutical resources. I argue that this approach is incomplete. It fails to capture an important species of hermeneutical injustice which doesn’t result from a lack (...) of hermeneutical resources, but from the overabundance of distorting and oppressive concepts which function to crowd-out, defeat, or preempt the application of a more accurate hermeneutical resource. I propose a broader analysis that better respects the dynamic relationship between hermeneutical resources and the social and political contexts in which they are implemented. (shrink)

The feeling of clarity can be dangerously seductive. It is the feeling associated with understanding things. And we use that feeling, in the rough-and-tumble of daily life, as a signal that we have investigated a matter sufficiently. The sense of clarity functions as a thought-terminating heuristic. In that case, our use of clarity creates significant cognitive vulnerability, which hostile forces can try to exploit. If an epistemic manipulator can imbue a belief system with an exaggerated sense of clarity, then they (...) can induce us to terminate our inquiries too early — before we spot the flaws in the system. How might the sense of clarity be faked? Let’s first consider the object of imitation: genuine understanding. Genuine understanding grants cognitive facility. When we understand something, we categorize its aspects more easily; we see more connections between its disparate elements; we can generate new explanations; and we can communicate our understanding. In order to encourage us to accept a system of thought, then, an epistemic manipulator will want the system to provide its users with an exaggerated sensation of cognitive facility. The system should provide its users with the feeling that they can easily and powerfully create categorizations, generate explanations, and communicate their understanding. And manipulators have a significant advantage in imbuing their systems with a pleasurable sense of clarity, since they are freed from the burdens of accuracy and reliability. I offer two case studies of seductively clear systems: conspiracy theories; and the standardized, quantified value systems of bureaucracies. (shrink)

What are conspiracy theories? And what, if anything, is epistemically wrong with them? I offer an account on which conspiracy theories are a unique way of holding a belief in a conspiracy. Specifically, I take conspiracy theories to be self-insulating beliefs in conspiracies. On this view, conspiracy theorists have their conspiratorial beliefs in a way that is immune to revision by counter-evidence. I argue that conspiracy theories are always irrational. Although conspiracy theories involve an expectation to encounter some seemingly disconfirming (...) evidence (allegedly planted by the conspirators), resistance to all counter- evidence cannot be justified on these grounds.

Disagreement and debunking arguments threaten religious belief. In this paper, I draw attention to two types of propositions and show how they reveal new ways to respond to debunking arguments and disagreement. The first type of proposition is the epistemically self-promoting proposition, which, when justifiedly believed, gives one a reason to think that one reliably believes it. Such a proposition plays a key role in my argument that some religious believers can permissibly wield an epistemically circular argument in response to (...) certain debunking arguments. The second type of proposition is the epistemically others-demoting proposition, which, when justifiedly believed, gives one a reason to think that others are unreliable with respect to it. Such a proposition plays a key role in my argument that some religious believers can permissibly wield a question-begging argument to respond to certain types of disagreement. (shrink)

Recent conversation has blurred two very different social epistemic phenomena: echo chambers and epistemic bubbles. Members of epistemic bubbles merely lack exposure to relevant information and arguments. Members of echo chambers, on the other hand, have been brought to systematically distrust all outside sources. In epistemic bubbles, other voices are not heard; in echo chambers, other voices are actively undermined. It is crucial to keep these phenomena distinct. First, echo chambers can explain the post-truth phenomena in a way that epistemic (...) bubbles cannot. Second, each type of structure requires a distinct intervention. Mere exposure to evidence can shatter an epistemic bubble, but may actually reinforce an echo chamber. Finally, echo chambers are much harder to escape. Once in their grip, an agent may act with epistemic virtue, but social context will pervert those actions. Escape from an echo chamber may require a radical rebooting of one's belief system.

Evidential Preemption occurs when a speaker asserts something of the form “Others will tell you Q, but I say P,” where P and Q are incompatible in some salient way. Typically, the aim of this maneuver is to get the audience to accept P despite contrary testimony of others, who might otherwise be trusted on the matter. Phenomena such as echo chambers, conspiracy theories, and other political speech of interest to epistemologists today, all commonly involve evidential preemption, so the question (...) arises: What effect, if any, does evidential preemption have on the audience's epistemic situation? In a widely discussed paper, Begby (Philosophy and Phenomenological Research, 2021, 102, 515) argues that evidential preemption can change the audience's epistemic situation in such a way that future testimony that Q, which would otherwise have been persuasive, can be rationally discounted to a significant degree. If so, evidential preemption is not a mere rhetorical flourish, but rather results in a rationally insulated belief that P. Since evidential preemption is a common feature of echo chambers and conspiracy theories, this would be a disturbing result. We bring good news: it is not so, at least not in the way Begby suggests. If evidential preemptions can change one's epistemic situation in a worrying way, it is a mystery how. (shrink)

Public support for responses to the coronavirus pandemic has sharply diverged on partisan lines in many countries, with conservatives tending to oppose lockdowns, social distancing, mask mandates and vaccines, and liberals far more supportive. This polarization may arise from the way in which the attitudes of each side is echoed back to them, especially on social media. In this paper, I argue that echo chambers are not to blame for this polarization, even if they are causally responsible for it. They (...) are not to blame, because belief calibration in an echo chamber is a rational process; moreover, the epistemically constitutive properties of echo chambers are not optional for epistemically social animals like us. There is no special problem of echo chambers; rather, there is a problem of misleading evidence (especially higher-order evidence). Accordingly, we ought to respond to misinformation about COVID neither by attempting to dismantle echo chambers nor by attempting to make people more rational, but rather by attempting to supplant unreliable higher-order evidence with better evidence.

In this paper, we will re-elaborate the notions of filter bubble and of echo chamber by considering human cognitive systems’ limitations in everyday interactions and how they experience digital technologies. Researchers who applied the concept of filter bubble and echo chambers in empirical investigations see them as forms of algorithmically-caused systems that seclude the users of digital technologies from viewpoints and opinions that oppose theirs. However, a significant majority of empirical research has shown that users do find and interact with (...) opposing views. Furthermore, we argue that the notion of filter bubble overestimates the social impact of digital technologies in explaining social and political developments without considering the not-only-technological circumstances of online behavior and interaction. This provides us with motivation to reconsider this notion’s validity and re-elaborate it in light of existing epistemological theories that deal with the discomfort people experience when dealing with what they do not know. Therefore, we will survey a series of philosophical reflections regarding the epistemic limitations of human cognitive systems. In particular, we will discuss how knowledge and mere belief are phenomenologically indistinguishable and how people’s experience of having their beliefs challenged is cause of epistemic discomfort. We will then go on to argue, in contrast with Pariser’s assumptions, that digital media users might tend to conform to their held viewpoints because of the “immediate” way they experience opposing viewpoints. Since online people experience others and their viewpoints as material features of digital environments, we maintain that this modality of confronting oneself with contrasting opinions prompts users to reinforce their preexisting beliefs and attitudes.

In any domain of inductive reasoning, we must take care to distinguish between (i) which hypothesis my evidence supports, and (ii) the level of confidence I should have in the hypothesis, given my evidence. This distinction can help resolve the problem of peer demotion, a central point of contention in the epistemology of peer disagreement. It is true that disagreement does not provide evidence that I am right and you are wrong. But it need not, in order to lead to (...) peer demotion: instead, significant disagreement can erode my confidence in the initial peer assessment to a point where I can no longer rationally sustain the belief that we are equally reliable. One consequence of this solution is that the line dividing the Equal Weight view from its competitors emerges as an artifact of a mistakenly one-dimensional picture of the epistemic significance of peer disagreement.
