Conspiracy theories hit us where we are intellectually most vulnerable. Like global skeptical scenarios that occupy and perplex philosophers, they suggest a gap between appearance and reality; they suggest that we have formed our beliefs on the basis of massively misleading evidence. Often, they concern possibilities that we have never even considered, let alone properly assessed. The volume of evidence and arguments that conspiracy theorists offer for their theories can be vast and intricate. Yet it seems that, in some cases, we are perfectly within our epistemic rights in dogmatically ignoring or avoiding this volume of evidence and arguments. This won't do as a general policy, though, for history forces us to admit that sometimes conspiracy theorists are right. Theories like Bayesian formal epistemology that seem well-suited to guide us through these difficult waters often make our situation even more puzzling and problematic. To make fresh headway on these issues, this course will look critically at how philosophers, psychologists and political scientists have approached conspiracy theories and conspiracy theorists. We will consider topics such as cognitive dysfunction and bias, epistemic trust, peer disagreement, the puzzle of misleading evidence, dogmatism, and formal theories of probabilistic reasoning. Along the way we will have occasion to consider many strange and fascinating conspiracy theories---a few of which have turned out to be true.
