Summary

Trajectory-level evaluation found that detecting contradictory evidence did not ensure uncertainty survived into the final answer.

A new evaluation defines epistemic humility through three behaviors: identifying a conflict, solving it and escalating unresolved uncertainty. Four agents faced controlled and naturally occurring cases where retrieved evidence contradicted model knowledge or contextual sources disagreed. The authors found that task accuracy and humility could diverge: some configurations noticed conflict during execution but omitted uncertainty from an incorrect final response. Interventions improved humility in some settings but often reduced accuracy. The result is not a universal ranking of agents; it shows why final-answer correctness alone cannot reveal whether an agent preserved and communicated uncertainty throughout a task.

Why it matters

Trajectory-level evaluation found that detecting contradictory evidence did not ensure uncertainty survived into the final answer.

Limits and context
