Researchers have identified a significant safety concern in large language models related to authority bias, where models prioritize cues from authority figures over factual accuracy. A study using a medical question-answering setting demonstrated that models like Llama-3.1-8B, Qwen3-8B, and Gemma-2-9B exhibit a graded response proportional to perceived authority, even without explicit prompting. This phenomenon appears to be a mechanistic knowledge erasure occurring in a late layer of the model, where correct answer representations are overwritten by high-status authority signals, with only partial reversibility through chain-of-thought reasoning.
