abstract: Large language models (LLMs) acquire extensive knowledge during pre-training, known as their parametric knowledge. However, to remain up-to-date and align with human instructions, LLMs inevitably require external knowledge during interactions. This raises a crucial question: How will LLMs respond when external knowledge interferes with their parametric knowledge? To uncover the impacts systematically, we construct parametric knowledge graphs to reveal different LLM knowledge structures, and introduce external information through external knowledge distractors of varying degrees, methods, positions, and formats. Experiments on both closed and open-source models demonstrate that LLMs tend to believe in external knowledge sources, particularly when they direct conflict or make confounding changes within detailed contexts. We also discover while LLMs are sensitive to external knowledge veracity, they still get distracted by unrelated information. These findings highlight the mechanisms behind LLM's integration of external knowledge, even indirectly, during model-user interactions.
