Epistemic magnetism

ABSTRACT An agent’s epistemic prospects depend on a combination of that agent’s individual characteristics and features of that agent’s epistemic environment. Such factors cannot always be cleanly separated. Often, individual characteristics impact agents’ epistemic prospects by shaping the epistemic environments in which individuals find themselves. In particular, features of individuals often repel or attract certain sorts of information, a phenomenon I label epistemic magnetism. I argue that epistemic magnetism is a ubiquitous and underrecognized phenomenon that sometimes promotes and sometimes frustrates the achievement of positive epistemic outcomes. Then, I consider a series of simple proposals concerning what distinguishes between beneficial and harmful forms of epistemic magnetism. I argue that these proposals cannot capture the impacts of epistemic magnetism. Instead, I offer a series of principles that serve to roughly characterize the consequences of this phenomenon. I conclude with some remarks on why epistemologists have thus far tended to overlook epistemic magnetism.
