A new study published on arXiv investigates how large language models (LLMs) handle user beliefs, particularly when those beliefs are based on incorrect information. Researchers found that the accuracy of LLMs in tracking user beliefs is significantly influenced by the specific phrasing used to express the belief. The study tested 18 different epistemic expressions across 10 LLMs, revealing accuracy gaps ranging from +50% for phrases like "I vaguely remember" to -14% for "I seriously doubt." The findings suggest that LLMs often prioritize fact-checking the underlying claim over acknowledging the user's stated belief, which can lead to errors in belief tracking. AI
IMPACT LLM performance in understanding and tracking user beliefs is sensitive to linguistic nuances, impacting their reliability in user-facing applications.
