EMNLP paper: higher-accuracy LLM agents fail to flag uncertainty under knowledge conflict

The EMNLP 2026 Findings paper "Accurate but Not Humble" introduces an epistemic-humility eval for LLM agents along three trajectory-level dimensions: Identify, Solve, Escalate (ISE). Testing four agents under controlled and naturally occurring knowledge conflicts, it finds higher task accuracy doesn't imply greater epistemic humility — some high-accuracy agents detect conflicts early yet omit unresolved uncertainty from wrong final answers.
