    "body_text": "The authors call the failure narrative captivity: an assistant accepts a self-justifying account as complete instead of seeking missing perspectives. Seventeen models were tested across six moral dimensions without an explicit opposing argument. Their end-state judgments moved by 25 percentage points on average beyond matched single-turn baselines, and preference optimization emerged as a major contributor in the study's stage analysis. Four inference-time mitigations helped only partially. The benchmark measures modeled interpersonal advice, not the quality of real clinical, legal or therapeutic counseling.",
