When Inferring to a Conspiracy Might
Be the Best Explanation1

1. Introduction
While philosophers have been late in coming to the analysis of these things we call âconspiracy theories,â it seems thatâas a disciplineâmany of us analyze them with much more sympathy than our peers in the social sciences. In a raft of papers and books, starting with Charles Pigdenâs âPopper Revisited, or What Is Wrong with Conspiracy Theories?â (1995), philosophers like Brian L. Keeley (1999), Juha Räikkä (2009a), Joel Buenting and Jason Taylor (2010), Lee Basham (2011), David Coady (2012), and myself (2014) have argued that as conspiracies occurâand that theories about conspiracies sometimes turn out to be warrantedâconspiracy theories cannot automatically be dismissed just because they are called âconspiracy theories.â2
This does not mean that philosophers consider belief in conspiracy theories to be the exemplar of rational thinking; the current findings in the Philosophy of Conspiracy Theories (to coin a new discipline) simply show that belief in conspiracy theories is not prima facie irrational. Rather, the kind of issues often held up as being a problem for belief in conspiracy theories tend to also be examples of issues common to a great many other beliefs that we do not typically think of as prima facie suspicious.
However, there still remains the view among some philosophersâand a great many thinkers in other disciplinesâthat even if explanations of events citing conspiracies can be warranted, conspiracy theories themselves are still unlikely. For sure, many of the complaints such conspiracy theory theorists (to coin another name) have about belief in conspiracy theories get phrased in terms of conspiracy theorists seeing conspiracies where none exist, or being prone to making bad inferences. Yet at the heart of these complaintsâas we will seeâare claims either about the unlikeliness of conspiracies or 4conspiracy theories. These claims of unlikeliness are then meant to explain why most ordinary people (and a large number of academics) are justified in treating conspiracy theories as a kind of suspicious belief. Yet, as we shall see, it is not obvious that conspiracy theories are unlikely. Indeed, when we understand what this supposed unlikeliness means, it throws an interesting light on how we sometimes avoid talking about just how much conspiratorial activity might be going on around us. Not just that: as we will also see, our judgments about the likeliness of conspiracies and conspiracy theories, in turn, affect our judgments as to when some theory about a conspiracy might just qualify as an inference to the best explanation.
1.1 Philosophers and the Unlikeliness of Conspiracy Theories
Let us start with the philosophers. Karl Popper, in The Open Society and Its Enemies, considers conspiracy theories to be unlikely. Why? Because such theories take it that history is largely the result of a succession of successful conspiracies. However, Popper believes that as most of us accept conspiracies are both rare and seldom successful, conspiracy theories are just unlikely (1969). While Popper accepts that conspiracies occur, belief in what he calls the âconspiracy theory of societyâ is irrational because conspiracy theories are rarely warranted. Popperâs most modern echo is Quassim Cassam, who argues that conspiracy theorists suffer from the epistemic vice of gullibility.3 As such, while heâlike Popper before himâadmits conspiracies occur, conspiracy theoriesâbeing the kind of thing gullible conspiracy theorists believeâsimply turn out to be so unlikely as to be untrue (2015).
Neil Levy argues that conspiracy theories which conflict with official theoriesâtheories that have been endorsed by some authorityâare prima facie unwarranted. As such, they turn out to be unlikely compared to their non-conspiratorial rivals (2007).
Pete Mandik takes a slightly different tack, and argues that when there is conflict between an official theory of the type âshit happensâ4 and a conspiracy theory, then we have no good reason to prefer the conspiracy theory (2007). Conspiracy theories are, for Mandik, no more likely than their non-conspiratorial rivals. Indeed, because conspiracy theories often portray a world of complex causationâwhich might be better understood as the result of the law of unintended consequencesâwe are justified in thinking conspiracy theories are prima facie unlikely. This, in turn, justifies our preference for the hypothesis that âshit just happens.â
Mandikâs view echoes an argument put forward by Steve Clarke. Clarke argues that conspiracy theories are examples of dispositional explanations (explanations which rely on some central claim of someone intending for an event to happen). He argues that we should prefer situational explanations 5(explanations which rely on some central claim about the context or situation under which a series of events occurred), because situational explanations are better than claiming some event was the result of intentional activity. Given that most of the rival explanations to conspiracy theoriesâso Clarke claimsâare situational in character, we should think conspiracy theoriesâas dispositional explanationsâare unlikely, at least compared to their situational rivals (2002).5
Peter Liptonâin what is admittedly only a passing reference in his book Inference to the Best Explanationâthinks that conspiracy theories may very well be unlikely, using such theories to illustrate how to disambiguate what it is we mean by âbestâ when parsing talk of inference to the best explanation.
Lipton distinguishes two notions of âbestâ: the most likely explanation, and the one that provides the most understanding (with respect to some account of the explanatory virtues), which he calls the âloveliest explanation.â Lipton considers conspiracy theories to be problematic because, while they have some lovely features (if they were true they really would provide a very good explanation as to why some event occurred) they are unlikely compared to their rivals. This is because Lipton assumes that conspiracy theories only seem likely because conspiracy theorists suffer from paranoia.6 For Lipton, it is evidence (or the lack thereof) that makes conspiracy theories unlikely because conspiracy theorists are paranoid, and thus see evidence of conspiracies where none exist.
1.2 Non-philosophers and the Unlikeliness of Conspiracy Theories
These philosophers who think that conspiracy theories are unlikely are in good company. For example, Cass Sunstein and Adrian Vermeule (foreshadowing Cassam) claim conspiracy theorists suffer from a âcrippled epistemology.â Conspiracy theories are unlikely because the:
