Stanford University researchers led by James Zou found that AI language models tend to use words with positive connotations disproportionately, such as commendable, meticulous, intricate, innovative, and versatile. This trend was observed in the use of ChatGPT among reviewers of scientific studies, with a significant impact on the quality of reviews. However, prestigious journals like those in the Nature group showed fewer traces of ChatGPT in corrections.
Andrew Gray, a librarian at University College London, made a surprising discovery after analyzing five million scientific studies published last year. He found a sudden increase in the use of certain words like meticulously, intricate, commendable, and meticulous in their English versions, with percentages ranging from 59% to 137%. Gray attributes this rise to the use of ChatGPT and similar AI-powered language generation programs by tens of thousands of researchers to write or polish their studies.
Gray estimates that over 60,000 scientific studies published in 2023 were created with the help of these AI tools. While some argue that AI is used to correct errors and improve text quality
