Bridging the Knowledge-Prediction Gap in LLMs on Multiple-Choice Questions

arXiv — cs.CLWednesday, December 10, 2025 at 5:00:00 AM
  • Recent research has identified a significant knowledge-prediction gap in Large Language Models (LLMs) when answering multiple-choice questions (MCQs). This gap arises from misalignment between the model's knowledge and its predictions, leading to incorrect answers despite the model's capability to generate accurate responses in other contexts. To address this issue, a new intervention called KAPPA has been introduced, which aligns the model's prediction with its knowledge base.
  • The introduction of KAPPA is crucial as it aims to enhance the performance of LLMs on MCQs, a common task in various applications, including education and assessment. By improving the alignment of predictions with knowledge, this development could lead to more reliable and accurate outputs from LLMs, thereby increasing their utility in real-world scenarios where precise answers are essential.
  • This advancement in LLMs reflects ongoing challenges in artificial intelligence, particularly regarding the consistency and reliability of model outputs. Issues such as belief updating, reasoning coherence, and the integration of structured knowledge sources like Knowledge Graphs are critical for enhancing LLM performance. The interplay between knowledge representation and decision-making processes continues to be a focal point in AI research, highlighting the complexity of developing models that can consistently deliver accurate predictions.
