Subcategory Generalism about Conspiracy Theories

I argue for a kind of sub-category generalism about conspiracy theories. I identify four features that negatively contribute to the evaluation of any conspiracy theory that has them. I argue that particularism about conspiracy theories is in conflict even with this moderate position. I explain the implications of sub-category generalism for questions about the epistemic environment in which epistemic agents operate. I argue that even if there are pragmatic reasons for being vigilant about the possibility of malign conspiracies, this does not support rejecting the claim that it is a prima facie epistemically wrong to believe a conspiracy with any of the four features I identify. I discuss how the favoured sub-category generalism may help to refine discussion about the relationship between the psychology of those who believe conspiracy theories and subjects who have delusions. There are grounds for thinking that believers in conspiracy theories display irrationality at least as bad as those suffering from delusions. This is not to pathologise believers in conspiracy theories but recognise the continuities between those who have delusions and believers who are not the subject of clinical attention.
