New study reveals how AI tools make human writing 'less personal'

A new study by a coalition of West Coast universities has raised significant concerns regarding the impact of artificial intelligence on human thought and expression.

Researchers found that heavy reliance on Large Language Models (LLMs) significantly alters the tone and substance of writing, often stripping it of personal conviction.

According to the findings, participants who depended on AI were 69 per cent more likely to provide neutral responses, showing a marked decrease in personal judgement compared to those writing unaided.

University of Washington computer science professor Natasha Jaques observed that these tools create a distinctive shift in prose.

She noted that the models generate a force that "drives essay writing away from any standard which a human writer would create," resulting in work that feels increasingly dull.

The research indicated that AI users utilised personal pronouns at only half the normal rate, replacing specific personal details with general expressions.

The study highlighted a fundamental change in how individuals perceive their own work when assisted by technology.

Participants admitted their output felt less creative and lacked their unique voice, despite remaining satisfied with the final result.

AI tools were found to perform extensive rewrites rather than minor corrections, often changing the original meaning of the text.

Florida State University professor Thomas Juzek remarked that the study demonstrates how these systems provide capabilities far beyond basic grammar assessment.

This discovery raises urgent questions about the future of human communication and the potential for AI to standardise artistic expression into a more formal, emotionally detached style.
