This paper explores how cultural identities are talked into being by examining how participants manage displayed gaps in what they might be obliged to know. Building on a rich tradition of research into error correction and conversational repair, I show how error correction practices – from “non-correction” (Jefferson, 1987 [2018]) to “embedded correction” (Jefferson, 1987) to “over-exposed correction” – can be used to negotiate identity-bound knowledge so as to ascribe particular cultural identities. I analyze how error correction practices are shaped by and adapted to the local interactional context in which an error is made, on the one hand, and to the identity ascribed to the error producer, on the other hand. Overall, the paper develops our understanding of epistemics (Heritage, 2013) as a resource for enacting identities in interaction, and elaborates the concept of epistemic responsibility.
