How Prompt Politeness Influences LLM Accuracy (2025)

The effect of prompt politeness on language model performance is an underexplored area. A recent study indicates that impolite prompts might enhance the accuracy of LLM responses.

Introduction

In the ever-evolving world of artificial intelligence, large language models (LLMs) like ChatGPT have revolutionized the way we interact with machines. As we refine prompts to obtain accurate responses, a question arises: does the tone and politeness of prompts affect the accuracy of LLMs? A recent study by Om Dobariya and Akhil Kumar, published in October 2025 on arXiv, explores this often-overlooked aspect of human-AI interaction.

Study Methodology

The study utilized a set of 50 base questions spanning mathematics, science, and history. Each question was rewritten into five tone variants: Very Polite, Polite, Neutral, Rude, and Very Rude, yielding 250 unique prompts. The ChatGPT 4.0 model was used to evaluate the responses to these prompts.

Surprising Results

The study's findings defied expectations. Very Rude prompts achieved an accuracy rate of 84.8%, while Very Polite prompts resulted in an accuracy of 80.8%. This contrasts with previous studies where rudeness was typically associated with poorer outcomes. This divergence highlights the evolution of LLMs and their response to tonal variations.

Implications and Reflections

These findings raise intriguing questions about the social dimensions of human-AI interaction. Why are impolite prompts more effective? Is it a matter of linguistic structure, or are language models biased to respond more efficiently to certain styles?

Limitations and Ethical Considerations

The study acknowledges several limitations, including the relatively small dataset size and the lack of in-depth analysis of the underlying reasons. More importantly, it raises ethical considerations about teaching users to formulate impolite prompts to optimize LLM performance.

Conclusion

The tone and politeness of prompts are crucial factors to consider when interacting with language models. By better understanding these dynamics, we can enhance LLM efficiency while ensuring ethical and respectful interactions.
