New research questions role-playing effectiveness in LLMs, proposes MLCP strategy

A new research paper explores the effectiveness of role-playing prompts in large language models (LLMs), finding that performance gains are highly dependent on the model's capacity, the knowledge domain, and the prompt's language. The study proposes the persona-related cognitive alignment hypothesis, suggesting role-play is effective only when the LLM accurately understands the persona and its associated knowledge. To improve consistency, the paper introduces Mixed-Language Concatenate Prediction (MLCP), a training-free prompt concatenation strategy that aggregates semantically equivalent prompts to enhance representational cues, demonstrating superior performance over standard role-playing across various LLMs. AI

IMPACT Suggests new methods for improving LLM reasoning and output quality beyond simple role-playing prompts.
