Stokes’ earlier chapter in this volume argued that, given the role ethical considerations play in our judgments of what to believe, ethical factors will put limits on the extent to which we can embrace particularism about conspiracy theories. However, that will only be the case if there are ethical problems with conspiracy theory as a practice (rather than simply as a formal class of explanation). Utilising the Lakatosian framework for analysing conspiracy theories developed by Steve Clarke, this paper identifies a (...) morally costly feature of conspiracy theorizing: its tendency to generate and expand new accusations purely to defend the core theory from countervailing evidence. Such 'auxiliary accusations' violate important norms around justified accusation, which supplies a defeasible, but important, reason to be reluctant to take part in the practice of conspiracy theorizing.

In this concluding chapter Dentith presents a synthesis of the views on offer, arguing that the various philosophical, sociological and psychology theses defended in this section point towards a necessary reorientation of the literature, one which requires we purge public discourse of the pejorative aspects of the terms ‘conspiracy theory’ and ‘conspiracy theorist’ and, rather, engage with conspiracy theories as theories (like we do with theories in the Sciences and the Social Sciences) appraising them on their particular merits. Not just (...) that, but there is even room in our discourse to celebrate and promote conspiracy theorising (as we do theorising in other domains) given the need to be ever vigilant with respect to the existence of conspiracies in our polities. Sometimes, Dentith argues, that even requires that we treat some on-the-face-of-it ridiculous conspiracy theories seriously and ask how and who should investigate them. (shrink)

In What particularism about conspiracy theories entails Dentith responds to their critics and examines the case for a refined and revised thesis of Particularism, the argument that we should appraise individual and particular conspiracy theories rather than appraise them in light of our views of the class of conspiracy theories generally. Recent work in the Philosophy of Conspiracy Theories has presented challenges to Particularism simpliciter (or Naive Particularism). Dentith argues that by facing these challenges Particularism presents an even stronger case (...) for rejecting a generalist conception of what belief in conspiracy theories entails. (shrink)

Belief in conspiracy theories is often taken to be a paradigm of epistemic irrationality. Yet, as I argue in the first half of this paper, standard criticisms of conspiracy theorising fail to demonstrate that the practice is invariably irrational. Perhaps for this reason, many scholars have taken a relatively charitable attitude toward conspiracy theorists and conspiracy theorising in recent years. Still, it would be a mistake to conclude from the defence of conspiracy theorising offered here that belief in conspiracy theories (...) is on an epistemic par with belief in other theories. I argue that a range of epistemic errors are pervasive among conspiracy theorists. First, the refusal of conspiracy theorists to accept the official account of some target event often seems to be due to the exercise of a probabilistic, and fallacious, extension ofmodus tollens. Additionally, conspiracy theorists tend to be inconsistent in their intellectual attention insofar as the effort they expend on uncovering the truth excludes attention to their own capacities for biased or otherwise erroneous reasoning. Finally, the scepticism with which conspiracy theorists tend to view common sources of information leaves little room for conspiracy theorists to attain positive warrant for their preferred explanations of target events.

Conpiracy theories are widely deemed to be superstitious. Yet history appears to be littered with conspiracies successful and otherwise. (For this reason, "cock-up" theories cannot in general replace conspiracy theories, since in many cases the cock-ups are simply failed conspiracies.) Why then is it silly to suppose that historical events are sometimes due to conspiracy? The only argument available to this author is drawn from the work of the late Sir Karl Popper, who criticizes what he calls "the conspiracy theory (...) of society" in The Open Society and elsewhere. His critique of the conspiracy theory is indeed sound, but it is a theory no sane person maintains. Moreover, its falsehood is compatible with the prevalence of conspiracies. Nor do his arguments create any presumption against conspiracy theories of this or that. Thus the belief that it is superstitious to posit conspiracies is itself a superstition. The article concludes with some speculations as to why this superstition is so widely believed. (shrink)

Traditional secular conspiracy theories and explanations of worldly events in terms of supernatural agency share interesting epistemic features. This paper explores what can be called “supernatural conspiracy theories”, by considering such supernatural explanations through the lens of recent work on the epistemology of secular conspiracy theories. After considering the similarities and the differences between the two types of theories, the prospects for agnosticism both with respect to secular conspiracy theories and the existence of God are then considered. Arguments regarding secular (...) conspiracy theories suggest ways to defend agnosticism with respect to God from arguments that agnosticism is not a logically stable position and that it ultimately collapses into atheism, as has been argued by N. Russell Hanson and others. I conclude that such attacks on religious agnosticism fail to appreciate the conspiratorial features of God's alleged role in the universe. (shrink)

Judging the warrant of conspiracy theories can be difficult, and often we rely upon what the experts tell us when it comes to assessing whether particular conspiracy theories ought to be believed. However, whereas there are recognised experts in the sciences, I argue that only are is no such associated expertise when it comes to the things we call `conspiracy theories,' but that the conspiracy theorist has good reason to be suspicious of the role of expert endorsements when it comes (...) to conspiracy theories and their rivals. The kind of expertise, then, we might associate with conspiracy theories is largely improvised—in that it lacks institutional features—and, I argue, ideally the product of a community of inquiry. (shrink)

The dismissive attitude of intellectuals toward conspiracy theorists is considered and given some justification. It is argued that intellectuals are entitled to an attitude of prima facie skepticism toward the theories propounded by conspiracy theorists, because conspiracy theorists have an irrational tendency to continue to believe in conspiracy theories, even when these take on the appearance of forming the core of degenerating research program. It is further argued that the pervasive effect of the "fundamental attribution error" can explain the behavior (...) of such conspiracy theorists. A rival approach due to Brian Keeley, which involves the criticism of a subclass of conspiracy theories on epistemic grounds, is considered and found to be inadequate. Key Words: conspiracy • conspiracy theories • conspiracy theorizing. (shrink)

We offer a particularist defense of conspiratorial thinking. We explore the possibility that the presence of a certain kind of evidence—what we call "fortuitous data"—lends rational credence to conspiratorial thinking. In developing our argument, we introduce conspiracy theories and motivate our particularist approach (§1). We then introduce and define fortuitous data (§2). Lastly, we locate an instance of fortuitous data in one real world conspiracy, the Watergate scandal (§3).

One issue within conspiracy theory theory is whether, or to what extent, our central concept – – should map on to the common, lay sense of the term. Some conspiracy theory theorists insist that we use the term as everyday people use it. So, for example, if the term has a pejorative connotation in everyday parlance, then academic work on the concept should reflect that. Other conspiracy theory theorists take a more revisionist approach, arguing instead that while their use of (...) the theoretical concept should bear some relation to its use in natural language, it need not follow it subserviently. I argue that elements of this debate mirror related debates that were prominent in the philosophy of mind in the 1980s over folk psychology and eliminative materialism (debates that continue today, such as within the philosophy of perception and theories over how to individuate the senses). Then, there was a debate over whether the concepts of commonsense psychology, such as or, should be treated as theoretical posits, and hence open to significant revision or elimination, or whether they were instead the targets of explanation. I will argue that an eliminativist approach to has significant merit. (shrink)

Conspiracy theories have a bad reputation. This is especially true in the academy and in the media. Within these institutions, to describe someone as a conspiracy theorist is often to imply that his or her views should not be taken seriously. Perhaps this accounts for the fact that philosophers have tended to ignore the topic, despite the enduring appeal of conspiracy theories in popular culture. Recently, however, some philosophers have at least treated conspiracy theorists respectfully enough to try to articulate (...) where they go wrong.I begin this paper by clarifying the nature of conspiracy theories. I then argue against some recent critiques of conspiracy theories. Many criticisms of conspiracy theories are unfounded. I also argue that unwillingness to entertain conspiracy theories is an intellectual and moral failing. I end by suggesting an Aristotelian approach to the issue, according to which the intellectual virtue of realism is a golden mean between the intellectual vices of paranoia and naivety. (shrink)

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. (shrink)

I argue that that an influential strategy for understanding conspiracy theories stands in need of radical revision. According to this approach, called ‘generalism’, conspiracy theories are epistemically defective by their very nature. Generalists are typically opposed by particularists, who argue that conspiracy theories should be judged case-by-case, rather than definitionally indicted. Here I take a novel approach to criticizing generalism. I introduce a distinction between ‘Dominant Institution Conspiracy Theories and Theorists’ and ‘Non-Dominant Institution Conspiracy Theories and Theorists’. Generalists uncritically center (...) the latter in their analysis, but I show why the former must be centered by generalists’ own lights: they are the clearest representatives of their views, and they are by far the most harmful. Once we make this change in paradigm cases, however, various typical generalist theses turn out to be false or in need of radical revision. Conspiracy theories are not primarily produced by extremist ideologies, as generalists typically claim, since mainstream, purportedly non-extremist political ideologies turn out to be just as, if not more responsible for such theories. Conspiracy theories are also, we find, not the province of amateurs: they are often created and pushed by individuals widely viewed as experts, who have the backing of our most prestigious intellectual institutions. While generalists may be able to take this novel distinction and shift in paradigm cases on board, this remains to be seen. Subsequent generalist accounts that do absorb this distinction and shift will look radically different from previous incarnations of the view. (shrink)

Conspiracy theories are frequently described as a threat to democracy and conspiracy theorists portrayed as epistemically or morally unreasonable. If these characterizations are correct, then it may be the case that reasons stemming from conspiracy theorizing threaten the legitimizing function of democratic deliberation. In this paper, I will argue the opposite. Despite the extraordinary epistemic and morally unreasonable claims made by some conspiracy theorists, belief in conspiracy theories is guided by internal epistemic norms inherent in believing. By utilizing the insights (...) of the Peircean epistemic defense formulated by Cheryl Misak and Robert Talisse, I take it that these epistemic norms implicitly commit the theorist to an open democratic society. (shrink)

Napolitano (2021) argues that the Minimalist Account of conspiracy theories—i.e., which defines conspiracy theories as explanations, or theories, about conspiracies—should be rejected. Instead, she proposes to define conspiracy theories as a certain kind of belief—i.e., an evidentially self-insulated belief in a conspiracy. Napolitano argues that her account should be favored over the Minimalist Account based on two considerations: ordinary language intuitions and theoretical fruitfulness. I show how Napolitano’s account fails its own purposes with respect to these two considerations and so (...) should not be favored over the Minimalist Account. Furthermore, I propose that the Minimalist Account is the best conception of ‘conspiracy theory’ if we share Napolitano’s goal of advancing the understanding of conspiracy theories. (shrink)

Drawing on the relevant alternatives framework and Mary Kate McGowan’s work on conversational scorekeeping, I argue that usage of the term ‘conspiracy theory’ in ordinary language and public discourse typically entails the performance of what I call a dismissive conversational exercitive, a kind of speech act that functions to exclude certain propositions from (or prevent their inclusion in) the set of alternatives considered relevant in a given conversational context. While it can be legitimate to perform dismissive conversational exercitives, excluding alternatives (...) that deserve to be taken seriously can be highly problematic for a variety of reasons. For one, it can give rise to what I call the problem of premature conclusions when subjects illegitimately dismiss certain propositions as irrelevant and, as a result, prematurely take certain conclusions or claims to be warranted. Depending on the kind of conclusion or claim, the problem can come in different variants, three of which I shall examine in more detail: the problem of premature knowledge claims, the problem of premature causal claims, and the problem of premature generic generalizations.

In an article based on a recent address to the Royal Institute of Philosophy, Keith Harris has argued that there is something epistemically wrong with conspiracy theorizing. Although he finds “standard criticisms” of conspiracy theories wanting, he argues that there are three subtle but significant problems with conspiracy theorizing: It relies on an invalid probabilistic version of modus tollens. It involves a problematic combination of both epistemic virtues and vices. And it lacks an adequate basis for trust in its information (...) sources. In response to Harris, this article argues that, like previous criticisms, these criticisms do little to undermine conspiracy theorizing as such. And they do not give us good reasons to dismiss any particular conspiracy theory without consideration of the relevant evidence. (shrink)

I present a conceptual framework for classifying generalist and particularist approaches to conspiracy theories (CTs). Specifically, I exploit a probabilistic version of the hexagon of opposition which allows for systematically visualising the logical relations among basic philosophical positions concerning CTs. The probabilistic interpretation can also account for positions, which make weaker claims about CTs: e.g. instead of claiming ‘every CT is suspicious’ some theorists might prefer to claim ‘most CTs are suspicious’ and then ask about logical consequences of such claims. (...) Finally, I illustrate the proposed conceptual framework by selected claims about CTs drawn from the CT research literature. (shrink)

Abstract The typical explanation of an event or process which attracts the label ‘conspiracy theory’ is an explanation that conflicts with the account advanced by the relevant epistemic authorities. I argue that both for the layperson and for the intellectual, it is almost never rational to accept such a conspiracy theory. Knowledge is not merely shallowly social, in the manner recognized by social epistemology, it is also constitutively social: many kinds of knowledge only become accessible thanks to the agent's embedding (...) in an environment that includes other epistemic agents. Moreover, advances in knowledge typically require ongoing immersion in this social environment. But the intellectual who embraces a conspiracy theory risks cutting herself off from this environment, and therefore epistemically disabling herself. Embracing a conspiracy theory therefore places at risk the ability to engage in genuine enquiry, including the enquiry needed properly to evaluate the conspiracy theory. (shrink)

Conspiracy theories and conspiracy theorists have been accused of a great many sins, but are the conspiracy theories conspiracy theorists believe epistemically problematic? Well, according to some recent work, yes, they are. Yet a number of other philosophers like Brian L. Keeley, Charles Pigden, Kurtis Hagen, Lee Basham, and the like have argued ‘No!’ I will argue that there are features of certain conspiracy theories which license suspicion of such theories. I will also argue that these features only license a (...) limited suspicion of these conspiracy theories, and thus we need to be careful about generalising from such suspicions to a view of the warrant of conspiracy theories more generally. To understand why, we need to get to the bottom of what exactly makes us suspicious of certain conspiracy theories, and how being suspicious of a conspiracy theory does not always tell us anything about how likely the theory in question is to be false. (shrink)

The papers contained in this special issue are evidence that the philosophy of conspiracy theory is undergoing a ‘normative turn’, with earlier concerns about the epistemological soundness of conspiracy theories now being supplemented by a shift to concerns about discursive and epistemic justice. This is a welcome development. Nonetheless, these normative concerns need to be seen within the context of an ongoing and largely undeclared disagreement between generalists and particularists over just how conspired the world really is.

I argue that ‘conspiracy theory’ and ‘conspiracy theorist’ as commonly employed are ‘tonkish’ terms (as defined by Arthur Prior and Michael Dummett), licensing inferences from truths to falsehoods; indeed, that they are mega-tonkish terms, since their use is governed by different and competing sets of introduction and elimination rules, delivering different and inconsistent results. Thus ‘conspiracy theory’ and ‘conspiracy theorist’ do not have determinate extensions, which means that generalizations about conspiracy theories or conspiracy theorists do not have determinate truth-values. Hence (...) conspiracy theory theory – psychological or social scientific research into conspiracy theorists and what is wrong with them – is often about as intellectually respectable as an enquiry into bastards and what makes them so mean. (shrink)

The pejorative connotation often associated with the ordinary language meaning of “conspiracy theory” does not only stem from a conspiracy theory’s being about a conspiracy, but also from a conspiracy theory’s being regarded as a particular kind of theory. I propose to understand conspiracy theory-induced polarization in terms of disagreement about the correct epistemic evaluation of ‘theory’ in ‘conspiracy theory’. By framing the positions typical in conspiracy theory-induced polarization in this way, I aim to show that pejorative conceptions of ‘conspiracy (...) theory’ are problematic for research open to the possibility of finding depolarization strategies. That is, because they preclude constructive engagement with the epistemic norms governing (the rationales foundational of) belief in conspiracy theories. (shrink)

Looking at the early work in the philosophy of conspiracy theory theory, I put in context the papers in this special issue on new work on conspiracy theory theory (itself the product of the 1st International Conference on the Philosophy of Conspiracy Theory held in February 2022), showing how this new generation of work not only grew out of, but is itself a novel extension of the first generation of philosophical interest in these things called ‘conspiracy theories’.

Using the example of recent attempts to engineer the concept of conspiracy theory, I argue that philosophers should be far more circumspect in their approach to conceptual engineering than we have been – in particular, that we should pay much closer attention to the history behind and context that surrounds our target concept in order to determine whether it is a site of what I have elsewhere called ‘conceptual domination’. If it is, we may well have good reason to avoid (...) engineering. In their recent ‘What is a Conspiracy Theory?’, M. Giulia Napolitano and Kevin Reuter argue that the disagreement between generalists and particularists in the literature on conspiracy theories is best characterized as a set of dueling conceptual engineering projects. While I agree with their turn to this metaphilosophical literature, I give a very different account of its applicability. Particularists, on my account, are better read as aiming to diagnose the ways in which many discussions of the concept of conspiracy theories are a form of conceptual domination, where this broader context should then prompt us to abandon or block any concept of conspiracy theory that treats its referents as inherently defective. Broader metaphilosophical lessons are drawn. (shrink)

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and exact form (...) of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

The popularity of conspiracy theories poses a clear challenge for contemporary liberal democracies. Conspiracy theories undermine rational debate, spread dangerous falsehoods and threaten social cohesion. However, any possible public policy response, which would try to contain their spread, needs to respect the liberal commitment to protect pluralism and free speech. A successful justification of such a policy must therefore: 1) clearly identify the problematic class of conspiracy theories; and 2) clarify the grounds on which the state is justified in acting (...) against them. This article argues that the prevailing epistemic approaches to conspiracy theorizing cannot fulfil these criteria. Defining conspiracy theories by their flaws in reasoning, questionable coherence or factual mistakes can neither sharply distinguish problematic conspiracy theories from other, non-problematic worldviews nor justify state action. Thus, we propose to understand conspiracy theories through their ethical unreasonableness. We hold that containment of conspiracy theories is justifiable insofar as they undermine the liberal-democratic ideals of mutual respect, freedom and equality. We then show that such ‘ethical’ criteria for conspiracy theories can be sufficiently robust and clear-cut so that they can serve as a useful guide for public policy. (shrink)

Vice epistemology is the philosophical study of the nature, identity, and epistemological significance of intellectual vices. Such vices include gullibility, dogmatism, prejudice, closed-mindedness, and negligence. These are intellectual character vices, that is, intellectual vices that are also character traits. I ask how the notion of an intellectual character vice should be understood, whether such vices exist, and how they might be epistemologically significant. The proposal is that intellectual character vices are intellectual character traits that impede effective and responsible inquiry. I (...) argue that situationist critiques of virtue epistemology pose no significant threat to this proposal. Studies by social psychologists of belief in conspiracy theories suggest that it is sometimes appropriate to explain questionable beliefs by reference to intellectual character vices. Neither ‘regulative’ nor ‘analytic’ epistemology has any good reason to question the epistemological significance of such vices. (shrink)

In Part 1, I contend (using Coriolanus as my mouthpiece) that Keeley and Clarke have failed to show that there is anything intellectually suspect about conspiracy theories per se. Conspiracy theorists need not commit the ‘fundamental attribution error’ there is no reason to suppose that all or most conspiracy theories constitute the cores of degenerating research programs, nor does situationism - a dubious doctrine in itself - lend any support to a systematic skepticism about conspiracy theories. In Part 2. I (...) argue (in propria persona) that the idea that there is something suspect about conspiracy theories is one of the most dangerous and idiotic superstitions to disgrace our political culture.
