Summary
An epistemic threat is a challenge to how we know things, as distinct from a challenge to any one thing we believe. ‘Epistemic’ comes from epistemology, the philosophical study of knowledge: its sources, its justification and its limits. We met the term in a 2025 episode of the podcast Planet: Critical, in which Damien Williams, who teaches philosophy and data science, “explains why other people’s realities feel threatening”, as host Rachel Donald puts it.
In Williams’s account the first response is to deny that the unsettling claim counts as knowledge at all. Sustained long enough, the challenge can deepen into ‘ontological shock’, a shaken sense of what is real.
Rationale
One account of why deep dispositions “generally can’t be reasoned with”: an argument that unsettles how someone knows, and not merely what they think, tends to land as danger. Hence our looking beyond persuasion.
