Research Indicates AI Editing Standardizes Writing Styles

A University of Southern California study, published in *Nature Human Behaviour*, reveals that generative AI tools like ChatGPT homogenize writing styles by reducing complexity variability by 21-50%. While preserving content, AI diminishes unique linguistic characteristics, potentially impacting the reliability of analytical methods used to infer personality or mental states from text. This could hinder the detection of conditions such as depression based on language patterns.
