Existing analyses of disinformation tend to embrace the view that disinformation is intended or otherwise functions to mislead its audience, that is, to produce false beliefs. I argue that this view is doubly mistaken. First, while paradigmatic disinformation campaigns aim to produce false beliefs in an audience, disinformation may in some cases be intended only to prevent its audience from forming true beliefs. Second, purveyors of disinformation need not intend to have any effect at all on their audience’s beliefs, aiming (...) instead to manipulate an audience’s behavior through alteration of sub-doxastic states. Ultimately, I argue that attention to such non-paradigmatic forms of disinformation is essential to understanding the threat disinformation poses and why this threat is so difficult to counter.

Since 2016, there has been an explosion of academic work and journalism that fixes its subject matter using the terms ‘fake news’ and ‘post-truth’. In this paper, I argue that this terminology is not up to scratch, and that academics and journalists ought to completely stop using the terms ‘fake news’ and ‘post-truth’. I set out three arguments for abandonment. First, that ‘fake news’ and ‘post-truth’ do not have stable public meanings, entailing that they are either nonsense, context-sensitive, or contested. (...) Secondly, that these terms are unnecessary, because we already have a rich vocabulary for thinking about epistemic dysfunction. Thirdly, I observe that ‘fake news’ and ‘post-truth’ have propagandistic uses, meaning that using them legitimates anti-democratic propaganda, and runs the risk of smuggling bad ideology into conversations.

It is widely accepted that electoral representative democracy is better—along a number of different normative dimensions—than any other alternative lawmaking political arrangement. It is not typically seen as much of a competition: it is also widely accepted that the only legitimate alternative to electoral representative democracy is some form of direct democracy, but direct democracy—we are told—would lead to bad policy. This article makes the case that there is a legitimate alternative system—one that uses lotteries, not elections, to select political (...) officials— that would be better than electoral representative democracy.

A scientific community can be modeled as a collection of epistemic agents attempting to answer questions, in part by communicating about their hypotheses and results. We can treat the pathways of scientific communication as a network. When we do, it becomes clear that the interaction between the structure of the network and the nature of the question under investigation affects epistemic desiderata, including accuracy and speed to community consensus. Here we build on previous work, both our own and others’, in (...) order to get a firmer grasp on precisely which features of scientific communities interact with which features of scientific questions in order to influence epistemic outcomes.

A central theme in social epistemology is that there are important and underappreciated phenomena involving social epistemic dependence—that is, epistemic dependence on other persons and on features of the broader social environment. Epistemologies that are inconsistent with this kind of dependence are labeled “individualist” and epistemologies that accommodate it are labeled “anti-individualist.” But how should the relevant notion of social epistemic dependence be understood? One important criterion for an adequate account is that it plausibly sorts epistemologies into the “individualist” and (...) “anti-individualist” categories. For example, standard reductionism about testimonial justification and knowledge should count as individualist, and many trust theories should count as anti-individualist. This paper argues that several accounts of social epistemic dependence in the literature fail to pass this simple sorting test. An alternative account that does is proposed. (shrink)

In this paper I will be arguing that there are cases in which a subject, S, should have known that p, even though, given her state of evidence at the time, she was in no position to know it. My argument for this result will involve making two claims. The uncontroversial claim is this: S should have known that p when another person has, or would have, legitimate expectations regarding S’s epistemic condition, the satisfaction of these expectations would require that (...) S knows that p, and S fails to know that p. The controversial claim is that these three conditions are sometimes jointly satisfied. I will spend the majority of my time defending the controversial claim. I will argue that there are two main sources of legitimate expectations regarding another’s epistemic condition: participation in a legitimate social practice ; and moral and epistemic expectations more generally . In developing my position on this score, I will have an opportunity to defend the doctrine that there are “practice-generated entitlements” to expect certain things, where it can happen that the satisfaction of these expectations requires another’s having certain pieces of knowledge; to contrast practice-generated entitlements to expect with epistemic reasons to believe; to defend the idea that moral and epistemic standards themselves can be taken to reflect legitimate expectations we have of each other; to compare the “should have known” phenomenon with a widely-discussed phenomenon in the ethics literature—that of culpable ignorance; and finally to suggest the bearing of the “should have known” phenomenon to epistemology itself.

In this paper I argue that the nature of our epistemic entitlement to rely on certain belief-forming processes—perception, memory, reasoning, and perhaps others—is not restricted to one's own belief-forming processes. I argue as well that we can have access to the outputs of others’ processes, in the form of their assertions. These two points support the conclusion that epistemic entitlements are “interpersonal.” I then proceed to argue that this opens the way for a non-standard version of anti-reductionism in the epistemology (...) of testimony, and a more “extended” epistemology—one that calls into question the epistemic significance that has traditionally been ascribed to the boundaries separating individual subjects. (shrink)

Mainstream epistemology is a highly theoretical and abstract enterprise. Traditional epistemologists rarely present their deliberations as critical to the practical problems of life, unless one supposes—as Hume, for example, did not—that skeptical worries should trouble us in our everyday affairs. But some issues in epistemology are both theoretically interesting and practically quite pressing. That holds of the problem to be discussed here: how laypersons should evaluate the testimony of experts and decide which of two or more rival experts is most (...) credible. It is of practical importance because in a complex, highly specialized world people are constantly confronted with situations in which, as comparative novices, they must turn to putative experts for intellectual guidance or assistance. It is of theoretical interest because the appropriate epistemic considerations are far from transparent; and it is not clear how far the problems lead to insurmountable skeptical quandaries. This paper does not argue for flat-out skepticism in this domain; nor, on the other hand, does it purport to resolve all pressures in the direction of skepticism. It is an exploratory paper, which tries to identify problems and examine some possible solutions, not to establish those solutions definitively. (shrink)

In other work I have defended the claim that, when we rely on other speakers by accepting what they tell us, our reliance on them differs in epistemically relevant ways from our reliance on instruments, when we rely on them by accepting what they “tell” us. However, where I have explored the former sort of reliance at great length, I have not done so with the latter. In this paper my aim is to do so. My key notions will be (...) those of our social practices, the normative expectations that are sanctioned by those practices, and the epistemically engineered environments constituted by some of these practices. With these notions in mind, I will argue that one’s reliance on instruments, while relevantly different from one’s reliance on other speakers, can nevertheless manifest a kind of epistemic dependence which epistemological theory can and should acknowledge.

This paper aims to understand the relationship between ignorance and vulnerability by drawing on recent work on the epistemology of ignorance. After elaborating how we might understand the importance of human vulnerability, I develop the claim that ignorance of vulnerability is produced through the pursuit of an ideal of invulnerability that involves both ethical and epistemological closure. The ignorance of vulnerability that is a prerequisite for such invulnerability is, I contend, a pervasive form of ignorance that underlies and grounds other (...) oppressive forms of ignorance. Thus, undoing such forms of ignorance requires working toward a particular form of vulnerability: epistemic vulnerability. (shrink)

Ignorance of one’s privileges and prejudices is an epistemic problem. While the sources of ignorance of privilege and prejudice are increasingly understood, less clarity exists about how to remedy ignorance. In fact, the various causes of ignorance can seem so powerful, various, and mutually reinforcing that studying the epistemology of ignorance can inspire pessimism about combatting socially constructed ignorance. I argue that this pessimism is unwarranted. The testimony of members of oppressed groups can often help members of privileged groups overcome (...) their ignorance. This paper argues that a particular type of speaker’s trust—hopeful trust—can motivate hearers to become cognizant of their privilege and prejudice. I argue that hopeful trust is a powerful way of eliciting trust-responsiveness that can be an effective mechanism for challenging privilege and prejudice. To make this case, I draw on case studies of online attempts to challenge ignorance. While the problems of testimonial injustice, defensi... (shrink)

We gain information from collective, often institutional bodies all the time—from the publications of committees, news teams, or research groups, from web sites such as Wikipedia, and so on—but do these bodies ever function as genuine group testifiers as opposed to mere group sources of information? In putting the question this way I invoke a distinction made, if briefly, by Edward Craig, which I believe to be of deep significance in thinking about the distinctiveness of the speech act of testimony. (...) The distinction is that between somebody’s functioning as a ‘good informant’ and their functioning merely as a ‘source of information’. The difference between these has, as he remarks, a crucial ethical aspect: What I have in mind is the special flavour of situations in which human beings treat each other as subjects with a common purpose, rather than as objects from which services, in this case true belief, can be extracted. In this paper I shall try to bring out the distinctive nature of the role of good informant in a way that helps to clarify what is at stake in asking whether there can be group testimony in the sense of genuinely collective testimony—that is to say, where the group testifier is a collective and not merely a sum of individuals testifying in one or another form of aggregated chorus.

Speaking with conversational AIs, technologies whose interfaces enable human-like interaction based on natural language, has become a common phenomenon. During these interactions, people form their beliefs due to the say-so of conversational AIs. In this paper, I consider, and then reject, the concepts of testimony-based beliefs and instrument-based beliefs as suitable for analysis of beliefs acquired from these technologies. I argue that the concept of instrument-based beliefs acknowledges the non-human agency of the source of the belief. However, the analysis focuses (...) on perceiving signs and indicators rather than content expressed in natural language. At the same time, the concept of testimony-based beliefs does refer to natural language propositions, but there is an underlying assumption that the agency of the testifier is human. To fill the lacuna of analyzing belief acquisition from conversational AIs, I suggest a third concept: technology-based beliefs. It acknowledges the non-human agency-status of the originator of the belief. Concurrently, the focus of analysis is on the propositional content that forms the belief. Filling the lacuna enables analysis that considers epistemic, ethical, and social issues of conversational AIs without excluding propositional content or compromising accepted assumptions about the agency of technologies.

Philosophers often find themselves in disagreement with contemporary philosophers they know full well to be their epistemic superiors on the topics relevant to the disagreement. This looks epistemically irresponsible. I offer a detailed investigation of this problem of the reflective epistemic renegade. I argue that although in some cases the renegade is not epistemically blameworthy, and the renegade situation is significantly less common than most would think, in a troublesome number of cases in which the situation arises the renegade is (...) blameworthy in her disagreement with recognized epistemic superiors. I also offer some thoughts on what it would mean for philosophical practice for us to refrain from being renegades. Finally, I show how a new kind of radical skepticism emerges from modest theses regarding the renegade. (shrink)

Two compelling principles, the Reasonable Range Principle and the Preservation of Irrelevant Evidence Principle, are necessary conditions that any response to peer disagreements ought to abide by. The Reasonable Range Principle maintains that a resolution to a peer disagreement should not fall outside the range of views expressed by the peers in their dispute, whereas the Preservation of Irrelevant Evidence Principle maintains that a resolution strategy should be able to preserve unanimous judgments of evidential irrelevance among the peers. No standard (...) Bayesian resolution strategy satisfies the PIE Principle, however, and we give a loss aversion argument in support of PIE and against Bayes. The theory of imprecise probability allows one to satisfy both principles, and we introduce the notion of a set-based credal judgment to frame and address a range of subtle issues that arise in peer disagreements.

“Mansplaining” is by now part of the common cultural vernacular. Yet, academic analyses of it—specifically, philosophical ones—are missing. This paper sets out to address just that problem. Analyzed through a lens of epistemic injustice, the focus of the analysis concerns both what it is, and what its harms are. I argue it is a form of epistemic injustice distinct from testimonial injustice wherein there is a dysfunctional subversion of the epistemic roles of hearer and speaker in a testimonial exchange. As (...) these are roles of power and are crucial to our existence and functioning within epistemic communities, the wrong and harms suffered from this injustice are serious and, I argue, distinct from other types already discussed in the literature. I close by considering an alternative model of mansplaining as a form of silencing, as well as briefly diagnosing its general underlying cause and possible solutions. (shrink)

Too often, identifying practices of silencing is a seemingly impossible exercise. Here I claim that attempting to give a conceptual reading of the epistemic violence present when silencing occurs can help distinguish the different ways members of oppressed groups are silenced with respect to testimony. I offer an account of epistemic violence as the failure, owing to pernicious ignorance, of hearers to meet the vulnerabilities of speakers in linguistic exchanges. Ultimately, I illustrate that by focusing on the ways in which (...) hearers fail to meet speaker dependency in a linguistic exchange, efforts can be made to demarcate the different types of silencing people face when attempting to testify from oppressed positions in society.

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

This book explores the epistemic side of racial and sexual oppression. It elucidates how social insensitivities and imposed silences prevent members of different groups from listening to each other.

The literature on the theory of social choice has grown considerably beyond the few items in existence at the time the first edition of this book appeared in 1951. Some of the new literature has dealt with the technical, mathematical aspects, more with the interpretive. My own thinking has also evolved somewhat, although I remain far from satisfied with present formulations. The exhaustion of the first edition provides a convenient time for a selective and personal stocktaking in the form of (...) an appended commentary entitled, 'Notes on the Theory of Social Choice, 1963, ' containing reflections on the text and its omissions and on some of the more recent literature. This form has seemed more appropriate than a revision of the original text, which has to some extent acquired a life of its own. (shrink)

In The Grammar of Society, first published in 2006, Cristina Bicchieri examines social norms, such as fairness, cooperation, and reciprocity, in an effort to understand their nature and dynamics, the expectations that they generate, and how they evolve and change. Drawing on several intellectual traditions and methods, including those of social psychology, experimental economics and evolutionary game theory, Bicchieri provides an integrated account of how social norms emerge, why and when we follow them, and the situations where we are most (...) likely to focus on relevant norms. Examining the existence and survival of inefficient norms, she demonstrates how norms evolve in ways that depend upon the psychological dispositions of the individual and how such dispositions may impair social efficiency. By contrast, she also shows how certain psychological propensities may naturally lead individuals to evolve fairness norms that closely resemble those we follow in most modern societies. (shrink)

Democracy is not naturally plausible. Why turn such important matters over to masses of people who have no expertise? Many theories of democracy answer by appealing to the intrinsic value of democratic procedure, leaving aside whether it makes good decisions. In Democratic Authority, David Estlund offers a groundbreaking alternative based on the idea that democratic authority and legitimacy must depend partly on democracy's tendency to make good decisions.Just as with verdicts in jury trials, Estlund argues, the authority and legitimacy of (...) a political decision does not depend on the particular decision being good or correct. But the "epistemic value" of the procedure--the degree to which it can generally be accepted as tending toward a good decision--is nevertheless crucial. Yet if good decisions were all that mattered, one might wonder why those who know best shouldn't simply rule.Estlund's theory--which he calls "epistemic proceduralism"--avoids epistocracy, or the rule of those who know. He argues that while some few people probably do know best, this can be used in political justification only if their expertise is acceptable from all reasonable points of view. If we seek the best epistemic arrangement in this respect, it will be recognizably democratic--with laws and policies actually authorized by the people subject to them. (shrink)

What is an assurance? What do we do when we claim to know? Krista Lawlor offers an original account based on the work of J. L. Austin. She addresses challenges to contextualist semantic theories; resolves closure-based skeptical paradoxes; and helps us tread the line between acknowledging our fallibility and skepticism.

In Black Feminist Thought, Patricia Hill Collins explores the words and ideas of Black feminist intellectuals as well as those African-American women outside academe. She not only provides an interpretive framework for the work of such prominent Black feminist thinkers as Angela Davis, Alice Walker, and Audre Lorde, but she shows the importance of self-defined knowledge for group empowerment. In the tenth anniversary edition of this award-winning work, Patricia Hill Collins expands the basic arguments of the first edition by adding (...) several important new themes. A new discussion of heterosexism as a system of power, an expanded treatment of images of Black womanhood, U.S. Black feminism's connections to Black Diasporic feminisms, and more attention to the importance of social class and nationalism all appear in the new edition. In addition, the new edition includes recent developments in black cultural studies, especially black popular culture, as well as recent events and trends such as the Anita Hill hearings and the backlash against affirmative action.

Paul Faulkner presents a new theory of testimony - the basis of much of what we know. He addresses the questions of what makes it reasonable to accept a piece of testimony, and what warrants belief formed on that basis. He rejects rival theories and argues that testimonial knowledge and testimonially warranted belief are based on trust.

Claims that science should be more democratic than it is frequently arouse opposition. In this essay, I distinguish my own views about the democratization of science from the more ambitious theses defended by Paul Feyerabend. I argue that it is unlikely that the complexity of some scientific debates will allow for resolution according to the methodological principles of any formal confirmation theory, suggesting instead that major revolutions rest on conflicts of values. Yet these conflicts should not be dismissed as irresoluble.

Leading scholars explore how different forms of ignorance are produced and sustained, and the role they play in knowledge practices.

In epistemology the nagging voice of the sceptic has always been present, whispering that 'You can't know that you have hands, or just about anything else, because for all you know your whole life is a dream.' Philosophers have recently devised ingenious ways to argue against and silence this voice, but Bryan Frances now presents a highly original argument template for generating new kinds of radical scepticism, ones that hold even if all the clever anti-sceptical fixes defeat the traditional sceptic. (...) Sharp, witty, and fun to read, Scepticism Comes Alive will be highly provocative for anyone interested in knowledge and its limits. (shrink)

Through communication, we form beliefs about the world, its history, others and ourselves. A vast proportion of these beliefs we count as knowledge. We seem to possess this knowledge only because it has been communicated. If those justifications that depended on communication were outlawed, all that would remain would be body of illsupported prejudice. The recognition of our ineradicable dependence on testimony for much of what we take ourselves to know has suggested to many that an epistemological account of testimony (...) should be essentially similar to accounts of perception and memory. This premise I want to dispute. (shrink)

Prototypical instances of disinformation include deceptive advertising (in business and in politics), government propaganda, doctored photographs, forged documents, fake maps, internet frauds, fake websites, and manipulated Wikipedia entries. Disinformation can cause significant harm if people are misled by it. In order to address this critical threat to information quality, we first need to understand exactly what disinformation is. This paper surveys the various analyses of this concept that have been proposed by information scientists and philosophers (most notably, Luciano Floridi). It (...) argues that these analyses are either too broad (that is, that they include things that are not disinformation), or too narrow (they exclude things that are disinformation), or both. Indeed, several of these analyses exclude important forms of disinformation, such as true disinformation, visual disinformation, side-effect disinformation, and adaptive disinformation. After considering the shortcomings of these analyses, the paper argues that disinformation is misleading information that has the function of misleading. Finally, in addition to responding to Floridi’s claim that such a precise analysis of disinformation is not necessary, it briefly discusses how this analysis can help us develop techniques for detecting disinformation and policies for deterring its spread.

Predatory grooming is a form of abuse most familiar from high-profile cases of sexual misconduct, for example, the Nassar case at Michigan State. Predatory groomers target individuals in a systematic effort to lead them into relationships in which they are vulnerable to exploitation. This is an example of a broader form of epistemic misconduct that Leydon-Hardy describes as epistemic infringement, where this involves the contravention of social and epistemic norms in a way that undermines our epistemic agency. In this chapter, (...) Leydon-Hardy looks at the distinctive epistemic harm caused by epistemic infringement. She argues that this harm cannot be understood simply as the victim’s having a false belief, or even as her being alienated from her belief-forming mechanisms. A deeper understanding of the harm caused by infringement shows that it stems from damage to one’s epistemic agency, and indeed, to one’s personhood. (shrink)

According to a theorem recently proved in the theory of logical aggregation, any nonconstant social judgment function that satisfies independence of irrelevant alternatives (IIA) is dictatorial. We show that the strong and not very plausible IIA condition can be replaced with a minimal independence assumption plus a Pareto-like condition. This new version of the impossibility theorem likens it to Arrow’s and arguably enhances its paradoxical value.

My conclusion will be that, more often than we might have thought, suspension of judgment is the epistemically proper attitude. It follows that in such cases we lack reasonable belief and so, at least on standard conceptions, knowledge. This is a kind of contingent real-world skepticism that has not received the attention it deserves. I hope that this paper will help to bring this issue to life.

We evaluate the asymptotic performance of boundedly-rational strategies in multi-armed bandit problems, where performance is measured in terms of the tendency (in the limit) to play optimal actions in either (i) isolation or (ii) networks of other learners. We show that, for many strategies commonly employed in economics, psychology, and machine learning, performance in isolation and performance in networks are essentially unrelated. Our results suggest that the appropriateness of various, common boundedly-rational strategies depends crucially upon the social context (if any) (...) in which such strategies are to be employed.

There are now several proposals for introducing random elements into the process of funding allocation for research, and some initial implementation of this policy by funding bodies. The proposals have been supported on efficiency grounds, with models, including social epistemology models, showing random allocation could increase the generation of significant truths in a community of scientists when compared to funding by peer review. The models in the literature are, however, fairly abstract. This paper introduces some of the considerations that are (...) required to build on the modelling work towards a fully-fledged policy proposal, including issues of cost and fairness. (shrink)

In this essay, I examine four different reasons for thinking that political dissent has epistemic value. The realization of this epistemic value hinges in part on what I’ll loosely call the epistemic environment, or the environment in which individuals come to believe, reason, inquire, and debate. In particular, to the degree that our social practices encourage and even embody an attitude of epistemic arrogance, the epistemic value of dissent will be difficult to realize. Ironically, it is precisely then that dissent (...) is most often needed. (shrink)

The aggregation of individual judgments over interrelated propositions is a newly arising field of social choice theory. I introduce several independence conditions on judgment aggregation rules, each of which protects against a specific type of manipulation by agenda setters or voters. I derive impossibility theorems whereby these independence conditions are incompatible with certain minimal requirements. Unlike earlier impossibility results, the main result here holds for any (non-trivial) agenda. However, independence conditions arguably undermine the logical structure of judgment aggregation. I therefore (...) suggest restricting independence to premises, which leads to a generalised premise-based procedure. This procedure is proven to be possible if the premises are logically independent. (shrink)
