Epistemic Observability in Language Models
📰 ArXiv cs.AI
Learn how epistemic observability in language models reveals that high confidence can indicate low accuracy, and how to address this issue in AI development
Action Steps
- Analyze the relationship between self-reported confidence and accuracy in language models using metrics like AUC
- Evaluate the observational capabilities of language models under text-only observation
- Apply formal assumptions to prove the existence of an observational gap in language models
- Develop methods to address the observational gap, such as using additional observational channels
- Test and validate the performance of language models using epistemic observability metrics

Title: Epistemic Observability in Language Models
Abstract:
arXiv:2603.20531v2 Announce Type: replace-cross Abstract: We find that models report highest confidence precisely when they are fabricating. Across four model families (OLMo-3, Llama-3.1, Qwen3, Mistral), self-reported confidence inversely correlates with accuracy, with AUC ranging from 0.28 to 0.36 where 0.5 is random guessing. We prove, under explicit formal assumptions, that this is not a capability gap but an observational one. Under text-only observation, where a supervisor sees only the mo
