A new research paper introduces the Epistemic Honesty Quotient (EHQ), a novel metric designed to evaluate how well large language models (LLMs) acknowledge the limits of their knowledge. The study constructed a 3,000-question benchmark, EHQ-3000, covering fabricated entities, post-cutoff events, niche truths, and context-conditioned questions. Analysis of 14 LLM API routes revealed significant variations in epistemic honesty, with composite EHQ scores ranging from 0.31 to 0.81, demonstrating that this behavioral measure captures differences not apparent in standard correctness-based assessments.

IMPACT Highlights the need for better evaluation of LLM confidence and knowledge boundaries, potentially influencing future model development and safety testing.
