Do LLMs Know What They Know? Measuring Metacognitive Efficiency with Signal Detection Theory

1. 1Decompose LLM evaluation into Type-1 sensitivity (knowledge) and Type-2 metacognitive sensitivity (self-awareness of knowledge)
2. 2Apply Signal Detection Theory to calculate meta-d' and M-ratio, providing a more accurate assessment of LLMs' metacognitive efficiency
3. 3Use the M-ratio to compare the metacognitive abilities of different LLMs, informing model selection and development decisions
4. 4Integrate this framework into existing evaluation pipelines to improve the reliability and trustworthiness of LLMs

AI researchers and engineers benefit from this framework as it provides a more nuanced understanding of LLMs' capabilities, allowing for more effective model evaluation and improvement
