This paper contributes to the growing literature in social epistemology of diagnosing the epistemically problematic features of fake news. I identify two novel problems: the problem of relevant alternatives; and the problem of the degradation of the epistemic environment. The former arises among individual epistemic transactions. By making salient, and thereby relevant, alternatives to knowledge claims, fake news stories threaten knowledge. The problem of the degradation of the epistemic environment arises at the level of entire epistemic communities. I introduce the (...) notion of an epistemic environment, roughly the totality of resources and circumstances relevant to assessing the epistemically interesting statuses, such as knowledge. Fake news degrades our epistemic environment by undermining confidence in epistemic institutions and altering epistemic habits, thereby making the environment less conducive to achieving positive epistemic statuses. This is problematic even if the decrease in confidence and the altering of habits are rational. I end by considering solutions to these problems, stressing the importance of reproaching each other for proliferating fake news. I argue that we should reproach even faultless purveyors of fake news. This is because fake news typically arises in abnormal epistemic contexts, where there is widespread ignorance of, and noncompliance with, correct epistemic norms. (shrink)

Truth monism is the idea that only true beliefs are of fundamental epistemic value. The present paper considers three objections to truth monism, and argues that, while the truth monist has plausible responses to the first two objections, the third objection suggests that truth monism should be reformulated. On this reformulation, which we refer to as accuracy monism, the fundamental epistemic goal is accuracy, where accuracy is a matter of “getting it right.” The idea then developed is that accuracy is (...) a genus with several species. Believing truly is a prominent species, but it is not the only one. Finally, it is argued that accuracy monism is equally good or better than both traditional truth monism and its main dialectical rival, value pluralism, when it comes to satisfying three important axiological desiderata.

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.

In this paper, I identify a form of epistemic insensitivity that occurs when someone fails to make proper use of the epistemic tools at their disposal in order to bring their beliefs in line with epistemically relevant evidence that is available to them. I call this kind of insensitivity agential insensitivity because it stems from the epistemic behavior of an individual agent. Agential insensitivity can manifest as a failure to either attend to relevant and available evidence, or appropriately interpret evidence (...) that is attended to. The concept of agential insensitivity allows us to conceptualize the kind of not-knowing involved in forms of ignorance that are cultivated and maintained by individual agents, especially when this ignorance is enabled or encouraged by social structures. I use the skepticism about racial disparities in policing practices that is displayed by many white Americans as a lens for exploring this connection. Understanding agential insensitivity thus provides insight into both social and epistemic phenomena. (shrink)

Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

Distinctions have been proposed between systems of reasoning for centuries. This article distills properties shared by many of these distinctions and characterizes the resulting systems in light of recent findings and theoretical developments. One system is associative because its computations reflect similarity structure and relations of temporal contiguity. The other is "rule based" because it operates on symbolic structures that have logical content and variables and because its computations have the properties that are normally assigned to rules. The systems serve (...) complementary functions and can simultaneously generate different solutions to a reasoning problem. The rule-based system can suppress the associative system but not completely inhibit it. The article reviews evidence in favor of the distinction and its characterization. (shrink)

My aim in this paper is to engage with C. Thi Nguyen’s characterization of the echo chamber and to propose two things. First, I argue that a proper reading of his concept of echo chamber should make use of the notion of ignorance in the form of a structural epistemic insensitivity. My main contention is that ignorance as a substantive structural practice accounts for the epistemically deleterious effects of echo chambers. Second, I propose that from the talk of ignorance we (...) should be able to see echo chambers in terms of their more harmful impacts in our daily lives. To do that, I argue that we should think of echo chambers as tools to promote hermeneutical domination. If my representation of Nguyen’s concept is accurate, I believe we can see some important theoretical consequences stemming from the way Nguyen understands it. (shrink)

Did you know that Hillary Clinton sold weapons to ISIS? Or that Mike Pence called Michelle Obama “the most vulgar First Lady we’ve ever had”? No, you didn’t know these things. You couldn’t know them, because these claims are false.1 But many American voters believed them.One of the most distinctive features of the 2016 campaign was the rise of “fake news,” factually false claims circulated on social media, usually via channels of partisan camaraderie. Media analysts and social scientists are still (...) debating what role fake news played in Trump’s victory.2 But whether or not it drove the outcome, fake news certainly affected the choices of some individual voters.Why were people willing to believe easily...

Thanks to the advent of social media, large numbers of Americans believe outlandish falsehoods that have been widely debunked. Many of us have a tendency to fault the individuals who hold such beliefs. We naturally assume that the individuals who form and maintain such beliefs do so in virtue of having violated some epistemic obligation: perhaps they failed to scrutinize their sources, or failed to seek out the available competing evidence. I maintain that very many ordinary individuals who acquire outlandish (...) false beliefs thanks to their use of popular social media platforms (and other similar internet technologies) deserve little or no blame for believing these falsehoods. Such individuals would be fully blameworthy only if they had formed or maintained the relevant beliefs partly in virtue of violating some epistemic obligation and had no excuse for violating that obligation. However, the nature of these internet technologies provides excuses for violating the relevant epistemic obligations, and so individuals are excused for holding the resulting false beliefs. (shrink)

When we ask a decision maker to express her preferences, it is typically assumed that we are eliciting a pre-existing set of preferences. However, empirical research has suggested that our preferences are often constructed on the fly for the decision problem at hand. This paper explores the ramifications of this empirical research for our understanding of instrumental rationality. First, I argue that these results pose serious challenges for the traditional decision-theoretic view of instrumental rationality, which demands global coherence amongst all (...) of one's beliefs and desires. To address these challenges, I first develop a minimal notion of instrumental rationality that issues in localized, goal-relative demands of coherence. This minimal conception of instrumental rationality is then used to offer a more sophisticated account of the global aspects of instrumental rationality. The resulting view abandons all-or-nothing assessments of rationality and allows us to evaluate decision makers as being rational to varying degrees. My aim is to propose a theory that is both psychologically and normatively plausible. (shrink)

Some people succeed in adopting feminist ideals in spite of the prevalence of asymmetric power relations. However, those who adopt such ideals face a number of psychological difficulties in inhibiting stereotype-based judgments. I argue that a Spinozan theory of belief fixation offers a more complete understanding of the mechanisms that underwrite our intuitive stereotype-based judgments. I also argue that a Spinozan theory of belief fixation offers resources for avoiding stereotype-based judgments where they are antecedently recognized to be pernicious and insidious. (...) Key Words: Spinozan theory of mind • stereotypes • feminism • dual-process theory. (shrink)

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.

This paper presents a partial analysis of perceptual knowledge, an analysis that will, I hope, lay a foundation for a general theory of knowing. Like an earlier theory I proposed, the envisaged theory would seek to explicate the concept of knowledge by reference to the causal processes that produce (or sustain) belief. Unlike the earlier theory, however, it would abandon the requirement that a knower's belief that p be causally connected with the fact, or state of affairs, that p.

Despite being a new term, ‘fake news’ has evolved rapidly. This paper argues that it should be reserved for cases of deliberate presentation of false or misleading claims as news, where these are misleading by design. The phrase ‘by design’ here refers to systemic features of the design of the sources and channels by which fake news propagates and, thereby, manipulates the audience’s cognitive processes. This prospective definition is then tested: first, by contrasting fake news with other forms of public (...) disinformation; second, by considering whether it helps pinpoint conditions for the proliferation of fake news.

Dual-process theories hold that there are two distinct processing modes available for many cognitive tasks: one that is fast, automatic and non-conscious, and another that is slow, controlled and conscious. Typically, cognitive biases are attributed to type 1 processes, which are held to be heuristic or associative, and logical responses to type 2 processes, which are characterised as rule-based or analytical. Dual-system theories go further and assign these two types of process to two separate reasoning systems, System 1 and System (...) 2 – a view sometimes described as ‘the two minds hypothesis’. It is often claimed that System 2 is uniquely human and the source of our capacity for abstract and hypothetical thinking. This study is an introduction to dual-process and dual-system theories. It looks at some precursors, surveys key work in the fields of learning, reasoning, social cognition and decision making, and identifies some recent trends and philosophical applications. (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)

Truth is standardly considered a requirement on epistemic acceptability. But science and philosophy deploy models, idealizations and thought experiments that prescind from truth to achieve other cognitive ends. I argue that such felicitous falsehoods function as cognitively useful fictions. They are cognitively useful because they exemplify and afford epistemic access to features they share with the relevant facts. They are falsehoods in that they diverge from the facts. Nonetheless, they are true enough to serve their epistemic purposes. Theories that contain (...) them have testable consequences, hence are factually defeasible. (shrink)

On many of the idealized models of human cognition and behavior in use by philosophers, agents are represented as having a single corpus of beliefs which (a) is consistent and deductively closed, and (b) guides all of their (rational, deliberate, intentional) actions all the time. In graded-belief frameworks, agents are represented as having a single, coherent distribution of credences, which guides all of their (rational, deliberate, intentional) actions all of the time. It's clear that actual human beings don't live up (...) to this idealization. The systems of belief that we in fact have are fragmented. Rather than having a single system of beliefs that guides all of our behavior all of the time, we have a number of distinct, compartmentalized systems of belief, different ones of which drive different aspects of our behavior in different contexts. It's tempting to think that, while of course people are fragmented, it would be better (from the perspective of rationality) if they weren't, and the only reason why our fragmentation is excusable is that we have limited cognitive resources, which prevents us from holding too much information before our minds at a time. Give us enough additional processing capacity, and there'd be no justification for any continued fragmentation. I argue that this is not so. There are good reasons to be fragmented rather than unified, independent of the limitations on our available processing power. In particular, there are ways our belief-forming mechanisms—including our perceptual systems—could be constructed that would make it better to be fragmented than to be unified. And there are reasons to think that some of our belief-forming mechanisms really are constructed that way. (shrink)

The epistemology of testimony has experienced a growth in interest over the last twenty-five years that has been matched by few, if any, other areas of philosophy. _Testimony: A Philosophical Introduction _provides an epistemology of testimony that surveys this rapidly growing research area while incorporating a discussion of relevant empirical work from social and developmental psychology, as well as from the interdisciplinary study of knowledge-creation in groups. The past decade has seen a number of scholarly monographs on the epistemology of (...) testimony, but there is a dearth of books that survey the current field. This book fills that gap, assessing the strengths and weaknesses of all major competing theories. All chapters conclude with Suggestions for Further Reading and Discussion Questions. (shrink)

Questo articolo prende in esame il fenomeno della proliferazione di fake news da un punto di vista filosofico—anzi, per meglio dire, prettamente epistemologico—con particolare attenzione a tre questioni fondamentali: cosa sono le fake news e come debbano essere definite; quali meccanismi ne favoriscono la proliferazione sui social media; chi debba essere ritenuto responsabile e degno di biasimo nel processo sotteso alla generazione, pubblicazione e diffusione di fake news. A partire dall'analisi dei principali lavori nella letteratura filosofica sul tema, ci proponiamo (...) di: offrire una definizione di fake news che eviti le obiezioni sollevate contro altre definizioni discusse dalla letteratura (§1); mettere in luce le principali cause della propagazione di fake news, con particolare riferimento ai bias cognitivi e alle strutture comunitarie in cui si organizzano gli utenti dei social media (§2); infine, presentare una analisi originale della responsabilità epistemica dei consumatori di fake news (§3).

‘Post-truth’ is a failed concept, both epistemically and politically because its simplification of the relationship between truth and politics cripples our understanding and encourages authoritarianism. This makes the diagnosis of our ‘post-truth era’ as dangerous to democratic politics as relativism with its premature disregard for truth. In order to take the step beyond relativism and ‘post-truth’, we must conceptualise the relationship between truth and politics differently by starting from a ‘non-sovereign’ understanding of truth.
