Reinforcement Learning with Metacognitive Feedback Elicits Faithful Uncertainty Expression in LLMs
arXiv:2606.32032v1 Announce Type: new Abstract: Metacognition is a critical component of intelligence that describes the ability to monitor and regulate one's own cognitive processes. Yet LLMs exhibit systemic deficiencies in key metacognitive faculties: they hallucinate with high confidence, fail to recognize knowledge boundaries, and misrepresent their internal uncertainty--undermining trustworthiness and reliability. Since monitoring task performance and adapting behavior accordingly are central to metacognition, we posit that models capable of accurately judging their own performance are b
The accelerating deployment of large language models across critical applications highlights the urgent need to address their inherent unreliability and confidence-calibration issues.
Improving LLM uncertainty expression directly enhances trustworthiness, enabling broader and safer integration into high-stakes decision-making and autonomous systems.
This research suggests a pathway to more reliable and self-aware AI, potentially altering the perceived risk and utility of AI agents.

More robust and less hallucination-prone LLMs become available for practical applications.
Increased trust in AI systems accelerates adoption across sensitive sectors, potentially leading to new regulatory frameworks for AI reliability.
The development of truly 'metacognitive' AI could fundamentally alter human-computer interaction, enabling more nuanced collaboration and reducing the need for constant human oversight for error correction.
