In this paper I develop a genealogical approach for investigating and evaluating conspiracy theories. I argue that conspiracy theories with an epistemically problematic genealogy are (in virtue of that fact) epistemically undermined. I propose that a plausible type of candidate for such conspiracy theories involves what I call ‘second-order conspiracies’ (i.e. conspiracies that aim to create conspiracy theories). Then, I identify two examples involving such conspiracies: the antivaccination industry and the industry behind climate change denialism. After fleshing out the mechanisms (...) by which these industries systematically create and disseminate specific types of conspiracy theories, I examine the implications of my proposal concerning the particularism/generalism debate and I consider the possibility of what I call local generalism. Finally, I tackle three objections. It could be objected that a problematic genealogy for T merely creates what Dentith (2022) calls ‘type-1’ (or ‘weak’) suspicion for T. I also consider a challenge according to which the genealogical method is meta-undermined, as well as an objection from epistemic laundering. (shrink)

Several philosophers and psychologists have characterized belief in conspiracy theories as a product of irrational reasoning. Proponents of conspiracy theories apparently resist revising their beliefs given disconfirming evidence and tend to believe in more than one conspiracy, even when the relevant beliefs are mutually inconsistent. In this paper, we bring leading views on conspiracy theoretic beliefs closer together by exploring their rationality under a probabilistic framework. We question the claim that the irrationality of conspiracy theoretic beliefs stems from an inadequate (...) response to disconfirming evidence and internal incoherence. Drawing analogies to Lakatosian research programs, we argue that maintaining a core conspiracy belief can be Bayes-rational when it is embedded in a network of auxiliary beliefs, which can be revised to protect the more central belief from disconfirmation. We propose that the irrationality associated with conspiracy belief lies not in a flawed updating method, but in a failure to converge toward wellconfirmed, stable belief networks in the long run. This approach not only reconciles previously disjointed views, but also points toward more specific descriptions of why agents may be prone to adopting beliefs in conspiracy theories. (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.

Conspiracy theories are often portrayed as unwarranted beliefs, typically supported by suspicious kinds of evidence. Yet contemporary work in Philosophy argues provisional belief in conspiracy theories is—at the very—least understandable (because conspiracies occur) and if we take an evidential approach—judging individual conspiracy theories on their particular merits—belief in such theories turns out to be warranted in a range of cases. Drawing on this work, I examine the kinds of evidence typically associated with conspiracy theories, showing that the evidential problems typically (...) associated with conspiracy theories are not unique to such theories. As such, if there is a problem with the conspiracy theorist’s use of evidence, it is one of principle: is the principle which guides their use of evidence somehow in error? I argue that whatever we might think about conspiracy theories generally, there is no prima facie case for a scepticism of conspiracy theories based purely on their use of evidence. (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)

In this paper I interrogate the notion of `debunking conspiracy theories’, arguing that the term `debunk’ carries with it pejorative implications, given that the verb `to debunk’ is commonly understood as `to show the wrongness of a thing or concept’. As such, the notion of `debunking conspiracy theories’ builds in the notion that such theories are not just wrong but ought to be shown as being wrong. I argue that we should avoid the term `debunk’ and focus on investigating conspiracy (...) theories. Looking at recent research work in epistemology on conspiracy theory, I argue that the best way to avoid talk of `debunking’ conspiracy theories is by working with a non-pejorative definition of `conspiracy theory’, and forming communities of inquiry which allow us to investigate the warrant of such theories without the prejudice associated with working with a pejorative definition.

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)

A reply to Patrick Stokes' “Between Generalism and Particularism About Conspiracy Theory".

Belief in conspiracy theories is typically considered irrational, and as a consequence of this, conspiracy theorists––those who dare believe some conspiracy theory––have been charged with a variety of epistemic or psychological failings. Yet recent philosophical work has challenged the view that belief in conspiracy theories should be considered as typically irrational. By performing an intra-group analysis of those people we call “conspiracy theorists”, we find that the problematic traits commonly ascribed to the general group of conspiracy theorists turn out to (...) be merely a set of stereotypical behaviours and thought patterns associated with a purported subset of that group. If we understand that the supposed prob- lem of belief in conspiracy theories is centred on the beliefs of this purported sub- set––the conspiracists––then we can reconcile the recent philosophical contribu- tions to the wider academic debate on the rationality of belief in conspiracy theories.

The simplest and most natural definition of the term ‘conspiracy theory’ leads us to the conclusion that we are all conspiracy theorists. Yet, I claim that most of us would not self-identify as such. In this paper I call this the problem of self-identification. Since virtually everyone emerges as a conspiracy theorist, the term is essentially theoretically fruitless. It would be like defining intelligence in a way that makes everyone intelligent. This raises the problem for theoretical fruitfulness, i.e. the problem (...) of how to define the concept in a theoretically fruitful way. I suggest that these problems are currently causing confusion in the literature and present us with a dilemma, the conspiracy definition dilemma. I will present an analysis of the literature and what are on my reconstruction the solutions on offer, and argue that none is satisfactory. Either a) the solution will solve the problem of self-identification or b) it will potentially provide a theoretical fruitful definition, but no account does both. (shrink)

As such, if there is a problem with the conspiracy theorist's use of evidence, it is one of principle: is the principle which guides the conspiracy theorist's use of evidence somehow in error?

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.

The question of the rationality of conspiratorial belief ¬divides philosophers into mainly two camps. The particularists believe that each conspiracy theory ought to be examined on its own merits. The generalist, by contrast, argues that there is something inherently suspect about conspiracy theories that makes belief in them irrational. Recent empirical findings indicate that conspiratorial thinking is commonplace among ordinary people, which has naturally shifted attention to the particularists. Yet, even the particularist must agree that not all conspiracy belief is (...) rational, in which case she must explain what separates rational from non-rational conspiratorial thinking. In this paper, I contrast three strategies to this end: 1) the probabilistic objectivist, who assesses the objective probability of conspiracies; 2) the subjectivist, who rather focuses on the perspective of the believer, and typically views the decision to believe in a conspiracy as a problem of decision making under risk. Approaches 1) and 2) rely on assessments of the probability of conspiracy which, I argue, limits their applicability. Instead, I explore 3) viewing the problem facing the potential believer as a decision problem under uncertainty about probabilities. I argue, furthermore, that focusing solely on epistemic utilities fails to do justice to the particular character of conspiracy beliefs, which are not exclusively epistemically motivated, and I investigate the rationality of such beliefs under a number of standard decision rules.

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’.

The contention in this paper is that the theological-political disputes Spinoza was concerned with 350 years ago are similar to the conspiratorial disputes we experience today. The world in Spinoza’s Tractatus theologico-politicus, a political intervention in his time, serves as a “mirror image”, that is to say, it deals with the same problem we face today albeit in a different mode. Understanding our contemporary condition under the auspices of a Spinozist perspective, problems in countermeasures to the conspiratorial disputes come to (...) light. Scholarly work and practice focus on the epistemological dimension of conspiracy theories, tying in the extent to which they are problematic to the degree in which they deal in untruth. However, the lesson from Spinoza’s analysis of the theological-political disputes is that such theories do not deal in truth, but, in affect, they do not spring from a lack of education but a lack of certainty. The work of Spinoza opens up a different approach, and if our aim is like that of the TTP, to defend political life against the threat of civil war, such a different approach is in order. (shrink)

Philosophy of the Social Sciences, Volume 52, Issue 4, Page 235-257, July 2022. Charles Pigden’s 1995 article “Popper Revisited, or What is Wrong with Conspiracy Theories?” stimulated what is today a fertile sub-field of philosophical enquiry into conspiracy theories. In his article, Pigden identifies Karl Popper as the originator of the philosophical argument that it is naïve to believe in any conspiracy theory. But Popper was not criticizing belief in conspiracy theories at all, as Pigden defined them or as they (...) have usually come to be understood since about the 1960s. Pigden has therefore fundamentally and anachronistically misinterpreted Popper. The object of Popper’s criticism was, rather, the inadequate approach to social science that is limited to the discovery of human intentions, including conspiracies, in particular the will of Great Men. Popper’s critique of the conspiracy theory of society was correct and should be rehabilitated. Pigden is correct only insofar as he concludes that we should not dismiss conspiracy theories without critical evaluation, a proposition with which Popper would likely have wholeheartedly agreed.

In the literature on conspiracy theories, the least contentious part of the academic discourse would appear to be what we mean by a “conspiracy”: a secretive plot between two or more people toward some end. Yet what, exactly, is the connection between something being a conspiracy and it being secret? Is it possible to conspire without also engaging in secretive behavior? To dissect the role of secrecy in con- spiracies – and thus contribute to the larger debate on the epistemology (...) of conspir- acy theories – we dene the concepts of “conspiracy,” “conspirator,” and “secret,” and argue that while conspirators might typically be thought to commit to keeping secrets once their conspiracy is underway, the idea that conspiracies are necessarily secretive to start with is not as obvious as previously thought.

In this article, I argue that online echo chambers are in some cases and in some respects good. I do not attempt to refute arguments that they are harmful, but I argue that they are sometimes beneficial. In the first section, I argue that it is sometimes good to be insulated from views with which one disagrees. In the second section, I argue that the software-design principles that give rise to online echo chambers have a lot to recommend them. Further, (...) the opposing principle, serendipity, could give rise to serious harm, in light of the conclusion of the first section that sometimes we are better off being insulated from some content online. In the third section, I argue that polarization can be a useful tool for inculcating the appropriate attitudes in a person. (shrink)

The COVID-19 pandemic has been accompanied by an “infodemic” of misinformation and conspiracy theory. This article points to three explanatory factors: the challenge of forming accurate beliefs when overwhelmed with information, an implausibly individualistic conception of epistemic virtue, and an adversarial information environment that suborns epistemic dependence. Normally we cope with the problems of informational excess by relying on other people, including sociotechnical systems that mediate testimony and evidence. But when we attempt to engage in epistemic “superheroics” - withholding trust (...) from others and trying to figure it all out for ourselves – these can malfunction in ways that make us vulnerable to forming irrational beliefs. Some epistemic systems are prone to coalescing audiences around false conspiracy theories. This analysis affords a new perspective on philosophical efforts to understand conspiracy theories and other epistemic projects prone to collective irrationality. (shrink)

Since the start of the Covid-19 pandemic in early 2020, conspiracy theories, misinformation, and fake news about the virus have abounded, drastically affecting global health measures to oppose it. In response, different strategies have been proposed to combat such Covid-19 collective irrationalities. One suggested approach has been that of epistemic paternalism – non-consultative interference in agents’ inquiries for their epistemic improvement. While extant literature on epistemic paternalism has mainly discussed whether it is (ever) justified, in this paper, I primarily focus (...) on the potential implementation of widespread epistemically paternalistic policies (such as no-platforming and censorship) and its consequences. I argue that pursuing epistemic paternalism to combat Covid-19 collective irrationalities leads to a hitherto unnoticed puzzle for proponents of epistemic paternalism. Central to the puzzle is the idea those (governments, corporations, social media giants) who actually can (i.e., have the requisite power to) enact widespread epistemically paternalistic policies seem the institutions who are least suited to having such informational control over the populace. Thus, epistemic paternalism appears a sword without a hilt; while it may prove an effective strategy in tackling Covid-19 collective irrationalities, we do not have any way to use it without incurring serious risks.

In “The Applied Epistemology of Official Stories” (2023), Tim Hayward offers a thorough and convincing rejection of Neil Levy’s claim that we ought to defer to official stories from relevant epistemic authorities. In this response, I take no issue with Hayward’s criticism of Levy. Rather, I suggest that Hayward’s position could go further, and he already implies a deeper problem with the concept of an ‘official story’. In fact, I’m so swayed by several of his claims against things called ‘official (...) stories’, that, in this essay, I investigate the feasibility of a generalist position towards ‘official stories’.
