We have increasingly sophisticated ways of acquiring and communicating knowledge, yet, paradoxically, we are currently facing an unprecedented global ignorance crisis that affects our personal and societal well-being, as well as the stability of our democracies. There are two key triggers to this crisis, i.e. two crucial obstacles to learning: first, the widespread sharing of disinformation, which, in conjunction with an overly trusting audience, contributes to widely spread false beliefs, and correspondingly reckless political and social behaviour. At the same time, though, and at least as critical, is the prevalence of knowledge resistance and distrust in expertise. What we need to solve this high-stakes puzzle is a social epistemological framework that is able to explain the complex mechanisms underlying these surprising and unprecedented epistemic phenomena. This article will aim to sketch the contours of such a framework.
