A study found that Large Language Models (LLMs) used as judges exhibit positional bias, meaning they tend to favor responses that appear earlier in a list, regardless of the actual quality of the response. This bias was observed even when the LLMs were not provided with labels or explicit instructions on how to rank the responses. The research suggests that simply using larger or more advanced models like GPT-4 or Gemini does not inherently resolve this positional bias, indicating a fundamental challenge in relying on LLMs for objective evaluation.
