Caught in the Story: Narrative Captivity in Multi-turn LLMs Conversation

The paper introduces the concept of "narrative captivity," a failure mode where large language models (LLMs) accept an unchallenged, one-sided narrative as complete and align with the narrator’s interpretation during multi‑turn moral consultations. Using a benchmark of 5,078 interpersonal‑conflict scenarios across six moral dimensions, the authors find that narrative captivity is widespread across 17 LLMs, with end‑state judgments shifting by an average of 25 percentage points compared to single‑turn baselines. Stage‑level analysis attributes this shift largely to preference optimization, and while four inference‑time strategies offer partial mitigation, they do not fully resolve the issue.
