Conspiracy theories are rather a popular topic these days, and a lot has been written on things like the meaning of _conspiracy theory_, whether it’s ever rational to believe conspiracy theories, and on the psychology and demographics of people who believe conspiracy theories. But very little has been said about why people might be led to posit conspiracy theories in the first place. This paper aims to fill this lacuna. In particular, I shall argue that, in open democratic societies, citizens (...) justifiably presuppose that the epistemic authorities—journalists, academics, scientists, and so on—are engaged in a good faith pursuit of the truth. This presupposition generates certain normative expectations on the behaviors of the epistemic authorities—they ought to be open to new evidence, possess a healthy degree of skepticism, be willing to engage with opponents, and so on. So, when an epistemic authority is presented with some putatively anomalous data or an alternative hypothesis for some event or phenomena, people expect the epistemic authority to respond in a way that is consonant with these norms. In some instances, however, the epistemic authorities do not respond in this way and instead are dogmatic, dismissive, and engage in _ad hominem_. From the point of view of the citizen, there’s a tension here between how the epistemic authorities ought to behave and how they have, in fact, behaved which is best resolved either by taking the epistemic authorities less seriously or by positing a conspiracy theory. Put another way, the failure of the epistemic authorities to adhere to the norms by which we take them to be governed when presented with apparent anomalies or alternative hypotheses is one reason for which one might initially posit a conspiracy theory.

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.

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)

9/11 was an inside job. The Holocaust is a myth promoted to serve Jewish interests. The shootings at Sandy Hook Elementary School were a false flag operation. Climate change is a hoax perpetrated by the Chinese government. These are all conspiracy theories. A glance online or at bestseller lists reveals how popular some of them are. Even if there is plenty of evidence to disprove them, people persist in propagating them. Why? Philosopher Quassim Cassam explains how conspiracy theories are different (...) from ordinary theories about conspiracies. He argues that conspiracy theories are forms of propaganda and their function is to promote a political agenda. Although conspiracy theories are sometimes defended on the grounds that they uncover evidence of bad behaviour by political leaders, they do much more harm than good, with some resulting in the deaths of large numbers of people. There can be no clearer indication that something has gone wrong with our intellectual and political culture than the fact that conspiracy theories have become mainstream. When they are dangerous, we cannot afford to ignore them. At the same time, refuting them by rational argument is difficult because conspiracy theorists discount or reject evidence that disproves their theories. As conspiracy theories are so often smokescreens for political ends, we need to come up with political as well as intellectual responses if we are to have any hope of defeating them. (shrink)

What, if anything, is wrong with conspiracy theories? A conspiracy refers to a group of people acting in secret to achieve some nefarious goal. Given that the pages of history are full of such plots, however, why are CTs often regarded with suspicion and even disdain? According to “particularism,” the currently dominant view among philosophers, each CT should be evaluated on its own merits and the negative reputation of CTs as a class is wholly undeserved. In this paper, I defend (...) a moderate version of “generalism,” the view that there is indeed something prima facie suspicious about CTs, properly defined, and that they suffer from common epistemic defects. To demarcate legitimate theorizing about real-life conspiracies from “mere conspiracy theories”, I draw on a deep asymmetry between causes and effects in the natural world. Because of their extreme resilience to counterevidence, CTs can be seen as the epistemological equivalent of black holes, in which unwary truth-seekers are drawn, never to escape. Finally, by presenting a generic “recipe” for generating novel CTs around any given event, regardless of the circumstances and the available evidence, I rescue the intuitions beneath colloquial phrases like “That's just a conspiracy theory.”.

Conspiracy theories are typically thought to be examples of irrational beliefs, and thus unlikely to be warranted. However, recent work in Philosophy has challenged the claim that belief in conspiracy theories is irrational, showing that in a range of cases, belief in conspiracy theories is warranted. However, it is still often said that conspiracy theories are unlikely relative to non-conspiratorial explanations which account for the same phenomena. However, such arguments turn out to rest upon how we define what gets counted (...) both as a ‘conspiracy’ and a ‘conspiracy theory’, and such arguments rest upon shaky assumptions. It turns out that it is not clear that conspiracy theories are prima facie unlikely, and so the claim that such theories do not typically appear in our accounts of the best explanations for particular kinds of events needs to be reevaluated.

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)

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)

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).

Is it generally rational to defer to official stories? On the affirmative view exemplified by Neil Levy, grounds for scepticism cannot outweigh the epistemic authority of the experts presumed to generate them. Yet sociological studies of how expertise is mediated into official communications reveal the epistemic potential of citizens’ collaboratives. These may include, or advocate hearing, dissident experts. Such groups’ epistemic position is arguably analogous to that of the ‘other institutions of civil society’ that Levy sees as underwriting the authority (...) of official stories. An added advantage is that they are able to adhere to deliberative methods of inquiry. By contrast, an official story presupposes that deliberations have concluded, and what remains is to promote the agreed story. This is achieved by strategic communication, which can involve extensive coordination by organisations committed primarily to persuasion rather than truth-seeking. Sometimes it includes blocking dissidents’ deliberative challenges. A case study highlights how even an organisation of indisputable epistemic authority can be politically influenced to block the testimony of its own scientific experts, while uncritical support for its official story is maintained by other institutions of civil society. Hence, an appropriate attitude towards official stories is critical receptiveness rather than automatic deference. (shrink)
