Quassim Cassam has argued that psychological and epistemological analyses of conspiracy theories threaten to overlook the political nature of such theories. According to Cassam, conspiracy theories are a form of political propaganda. I develop a limited critique of Cassam's analysis.This paper advances two core theses. First, acceptance of conspiracy theories requires a rejection of epistemic authority that renders conspiracy theorists susceptible to co-option by certain political programs while insulating such programs from criticism. I argue that the contrarian nature of conspiracy (...) theories partially accounts for the prominence of such theories in populist movements.Second, the contrarian nature of conspiracy theories partially accounts for their attractiveness, especially among those to whom populism already appeals. I argue that for those who resent what appears from their perspective as the shaping of the epistemic landscape by alien perspectives, conspiracy theorizing may facilitate the reassertion of epistemic autonomy.

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.

What happens to the "conversational score" when speakers in a conversation push the score for a context-sensitive term in different directions? In epistemology, contextualists are often construed as holding that both the skeptic ("You don't know!") and her opponent ("Oh, yes I do!") speak truthfully when they debate. This assumes a "multiple scoreboards" version of contextualism. But contextualists themselves typically opt for "single scoreboard" views on which such apparently competing claims really do conflict. This paper explores several single scoreboard options (...) for contextualists, opting in the end for the "gap view," on which neither of our debaters speaks truthfully. (shrink)

This paper defends two main theses related to emerging deepfake technology. First, fears that deepfakes will bring about epistemic catastrophe are overblown. Such concerns underappreciate that the evidential power of video derives not solely from its content, but also from its source. An audience may find even the most realistic video evidence unconvincing when it is delivered by a dubious source. At the same time, an audience may find even weak video evidence compelling so long as it is delivered by (...) a trusted source. The growing prominence of deepfake content is unlikely to change this fundamental dynamic. Thus, through appropriate patterns of trust, whatever epistemic threat deepfakes pose can be substantially mitigated. The second main thesis is that focusing on deepfakes that are intended to deceive, as epistemological discussions of the technology tend to do, threatens to overlook a further effect of this technology. Even where deepfake content is not regarded by its audience as veridical, it may cause its viewers to develop psychological associations based on that content. These associations, even without rising to the level of belief, may be harmful to the individuals depicted and more generally. Moreover, these associations may develop in cases in which the video content is realistic, but the audience is dubious of the content in virtue of skepticism toward its source. Thus, even if—as I suggest—epistemological concerns about deepfakes are overblown, deepfakes may nonetheless be psychologically impactful and may do great harm. (shrink)

This paper describes the ways in which trolls and bots impede the acquisition of knowledge online. I distinguish between three ways in which trolls and bots can impede knowledge acquisition, namely, by deceiving, by encouraging misplaced skepticism, and by interfering with the acquisition of warrant concerning persons and content encountered online. I argue that these threats are difficult to resist simultaneously. I argue, further, that the threat that trolls and bots pose to knowledge acquisition goes beyond the mere threat of (...) online misinformation, or the more familiar threat posed by liars offline. Trolls and bots are, in effect, fake persons. Consequently, trolls and bots can systemically interfere with knowledge acquisition by manipulating the signals whereby individuals acquire knowledge from one another online. I conclude with a brief discussion of some possible remedies for the problem of fake persons. (shrink)

Particularists maintain that conspiracy theories are to be assessed individually, while generalists hold that conspiracy theories may be assessed as a class. This paper seeks to clarify the nature and importance of the debate between particularism and generalism, while offering an argument for a version of generalism. I begin by considering three approaches to the definition of conspiracy theory, and offer reason to prefer an approach that defines conspiracy theories in opposition to the claims of epistemic authorities. I argue that (...) particularists rely on an untenably broad definition of conspiracy theory. Then, I argue that particularism and its counterpart are best understood as constellations of theses, rather than a pair of incompatible theses. While some particularist theses are highly plausible, I argue that one important particularist thesis is false. The argument for this conclusion draws on the history of false conspiracy theories. I then defend this conclusion against a pair of potential objections. (shrink)

Many of our beliefs are acquired online. Online epistemic environments are replete with fake news, fake science, fake photographs and videos, and fake people in the form of trolls and social bots. The purpose of this paper is to investigate the threat that such online fakes pose to the acquisition of knowledge. I argue that fakes can interfere with one or more of the truth, belief, and warrant conditions on knowledge. I devote most of my attention to the effects of (...) online fakes on satisfaction of the warrant condition, as these have received comparatively little attention. I consider three accounts of the conditions under which fakes compromise the warrant condition. I argue for the third of these accounts, according to which the propensity of fakes to exist in an environment threatens warrant acquisition in that environment. Finally, I consider some limitations on the epistemic threat of fakes and suggest some strategies by which this threat can be mitigated. (shrink)

Practical deliberation often involves conditional judgements about what will happen if certain alternatives are pursued. It is widely assumed that the conditionals useful in deliberation are counterfactual or subjunctive conditionals. Against this, I argue that the conditionals of deliberation are indicatives. Key to the argument is an account of the relation between ‘straightforward’ future-directed conditionals like ‘If the house is not painted, it will soon look quite shabby’ and ‘ “were”ed-up’ FDCs like ‘If the house were not to be painted, (...) it would soon look quite shabby’: an account on which both of these types of FDCs are grouped with the indicatives for semantic treatment and on which, while conditionals of both types are properly used in means/ends deliberations, those of the ‘were’ed-up variety are especially well suited for that purpose.

Deepfakes pose a multi-faceted threat to the acquisition of knowledge. It is widely hoped that technological solutions—in the form of artificially intelligent systems for detecting deepfakes—will help to address this threat. I argue that the prospects for purely technological solutions to the problem of deepfakes are dim. Especially given the evolving nature of the threat, technological solutions cannot be expected to prevent deception at the hands of deepfakes, or to preserve the authority of video footage. Moreover, the success of such (...) technologies depends on institutional trust that is in short supply. Finally, outsourcing the discrimination between the real and the fake to automated, largely opaque systems runs the risk of undermining epistemic autonomy. (shrink)

Despite clear overlap between the study of extended minds and the study of group minds, these research programs have largely been carried out independently. Moreover, whereas proponents of the extended mind thesis straightforwardly advocate the view that there are, literally, extended mental states, proponents of the group mind thesis tend to be more circumspect. Even those who advocate for some version of the thesis that groups are the subjects of mental states often concede that this thesis is true only in (...) some loose or metaphorical sense. I argue that this imbalance is a mistake. A literal interpretation of the group mind thesis is no less plausible than the extended mind thesis, because group minds are particularly defensible instances of extended minds. However, the extended mind thesis, and the view that group minds are extended minds, are defensible only following a revision of the extended mind thesis. (shrink)

Recent theories of negative freedom see it as a value-neutral concept; the definition of freedom should not be in terms of specific moral values. Specifically, preferences or desires do not enter into the definition of freedom. If preferences should so enter then Berlin's problem that a person may enhance their freedom by changing their preferences emerges. This paper demonstrates that such a preference-free conception brings its own counter-intuitive problems. It concludes that these problems might be avoided if the description of (...) the constraints which specify an agent's lack of freedom include the intentions of those who constrain the agents.

This paper attacks the Implicit Reference Class Theory of gradable adjectives and proposes instead a ?pluralist? approach to the semantics of those terms, according to which they can be governed by a variety of different types of standards, one, but only one, of which is the group-indexed standards utilized by the Implicit Reference Class Theory.

Psychological-epistemic accounts take scientific progress to consist in the development of some psychological-epistemic attitude. Disagreements over what the relevant attitude is – true belief, knowledge, or understanding – divide proponents of thesemantic,epistemic,andnoeticaccounts of scientific progress, respectively. Proponents of all such accounts face a common challenge. On the face of it, only individuals have psychological attitudes. However, as I argue in what follows, increases in individual true belief, knowledge, and understanding are neither necessary nor sufficient for scientific progress. Rather than being (...) fatal to the semantic, epistemic, and noetic accounts, this objection shows that these accounts are most plausible when they take the psychological states relevant to scientific progress to be states of communities, rather than individuals. I draw on recent work in social epistemology to develop two ways in which communities can be the bearers of irreducible psychological-epistemic states. Each way yields a strategy by which proponents of one of the psychological-epistemic accounts might attempt to account for the social dimensions of scientific progress. While I present serious reasons for concern about the first strategy, I argue that the second strategy, at least, offers a promising path forward for a psychological-epistemic account of scientific progress.

Philosophers and psychologists have devoted considerable attention to the study of intellectual humility and intellectual arrogance. To this point, theoretical and empirical studies of intellectual humility and arrogance have focused on these traits as possessed by individual reasoners. However, it is natural in some contexts to attribute intellectual humility or intellectual arrogance to collectives. This paper investigates the nature of collective intellectual humility and arrogance and, in particular, how these traits are related to the attitudes of individuals. I discuss three (...) approaches to collective intellectual humility and arrogance. Rather than arguing that one of these approaches is applicable to all instances of collective intellectual humility and arrogance, I argue that there are at least two and perhaps three distinct forms of both collective intellectual humility and arrogance. Recognizing these distinct forms of collective intellectual humility and arrogance, I argue, is crucial to understanding how intellectual humility and arrogance are related to troubling phenomena like political polarization.

The role of moral intuition has been increasingly implicated in business decisions and ethical business behavior. But troublingly, because implicit processes often operate outside of conscious awareness, decision makers are generally unaware of their influence. We tested whether subtle contextual cues for identity can alter implicit beliefs. In two studies, we found that contextual cues which nonconsciously prime moral identity weaken the implicit association between the categories of “business” and “ethical,” an implicit association which has previously been linked to unethical (...) decision making. Further, changes in this implicit association mediated the relationship between contextually primed moral identity and concern for external stakeholder groups, regardless of self-reported moral identity. Thus, our results show that subtle contextual cues can lead individuals to render more ethical judgments, by automatically restructuring moral intuition below the level of consciousness. (shrink)

This paper identifies and elucidates the underappreciated phenomenon of epistemic domination. Epistemic domination is the nonmutual capacity of one party to control the evidence available to another. Where this capacity is exercised, especially by parties that are ill-intentioned or ill-informed, the dominated party may have difficulty attaining epistemically valuable states. I begin with a discussion of epistemic domination and how it is possible. I then highlight three negative consequences that may result from epistemic domination.

The epistemic virtues and vices are typically defined in terms of effects or motivations related to the epistemic states of their possessors. However, philosophers have recently begun to consider _other-regarding_ epistemic virtues, traits oriented toward the epistemic flourishing of others. In a similar vein, this paper discusses _outward-facing_ epistemic vices, properties oriented toward the epistemic languishing of others. I argue for the existence of both reliabilist and responsibilist outward-facing vices, and illustrate how such vices negatively bear on the epistemic prospects (...) of others. I pay special attention to how outward-facing epistemic vices may manifest in online activities that promote the epistemic languishing of others by negatively influencing the online epistemic environment.

exactly as the essay appears in Skepticism. It's pretty close, though. In the version that appears in the book, page references to other essays in Skepticism refer to page numbers in the book, while below page references are, for the most part, to the original place of publication of the essays referred to. Also, I below make one correction (in red) of a factual error..

Republican freedom is freedom from domination juxtaposed to negative freedom as freedom from interference. Proponents argue that republican freedom is superior since it highlights that individuals lose freedoms even when they are not subject to interference, and claim republican freedom is more ‘resilient’. Republican freedom is trivalent, that is, it includes the idea that someone might be non-free to perform some actions rather than unfree, and in that sense everyone regards republican freedom as different from negative freedom. Trivalence makes republican (...) freedom moralized according to negative libertarians. Beyond that, negative libertarians argue that all the supposed advantages of republican freedom are compatible with those of pure negative-freedom measures. That is, losses and gains of republican freedom are captured in measures of pure negative freedom, and any protection for republican freedom also protects negative freedom, ensuring each is equally resilient. Since republican freedom has no advantages over negative freedom, but has other problems (is moralized and is trivalent), negative freedom is superior. I examine this debate in this article through the ‘coalition problem’ for republican freedom. The coalition problem is that since there is always a coalition of others who could dominate any agent in any sphere, all agents are subject to domination, and hence no one can ever have republican freedom. Pettit’s simple solution to this reductio ad absurdum distinguishes potential from actual coalitions. Individuals are only dominated by actual coalitions, and not by potential ones. The simple solution highlights moralization problems as it demonstrates that domination cannot be purely institutionally defined, but requires consideration of dispositions and expectations about others’ behaviour. I argue that the differences between the ‘free man’ and ‘unfree person’ paradigmatic to republican arguments is best captured not by the difference between domination and interference, but, rather, from familiar distinctions between different types of rights and freedoms. Resilience is a practical matter that might track some of these familiar distinctions. (shrink)

Discretion is a pervasive phenomenon in legal systems. It is of concern to lawyers because it can be a force for justice or injustice: at once a means of advancing the broad purposes of law and of subventing them. For social scientists the discretion exercised by legal actors is an important form of decision-making behaviour, in which legal rules are merely one force in a field of pressures and constraints that push towards certain courses of action or inaction. This book (...) presents a variety of analyses of legal discretion by lawyers and social scientists, who have made discretion and its uses a central part of their scholarly concerns. (shrink)
