Large Language Models (LLMs) struggle to admit when they don't know something, a problem that stems from how they are trained and evaluated.

This can lead to "hallucinations" where models generate plausible but false information. Addressing this requires a shift in evaluation metrics to better penalize incorrect assertions and reward accurate admissions of ignorance. AI
