Self-narration, many philosophers assume, makes important contributions to our mental lives. Two views on self-narration can be distinguished. On the internalistic view, self-narration unfolds in the secluded mind and does not require overt communication. On the situated view, self-narration often depends on the conversational interaction with an interlocutor. The situated view has many advantages over its internalistic rival, including theoretical consistency and empirical plausibility. Yet, research on situated conversational self-narration has been shaped by a harmony bias, which consists in the (...) tacit assumption that interlocutors contribute to self-narration in ways that are beneficial and supportive, rather than malicious and harmful. This paper seeks to mitigate the harmony bias by considering the phenomenon of gaslighting, which is characterized by an interlocutor’s erosion of someone’s sense of epistemic and moral competence. In cases of narrative gaslighting, this erosion proceeds by maliciously interfering with the self-narrator’s mnemonic, interpretational, and conceptual abilities. Bringing together research on situated self-narration and gaslighting for the first time, it will be argued that the emerging account of narrative gaslighting has important implications for both.
