Academic journals' AI policies fail to curb the surge in AI-assisted academic writing

The rapid integration of generative AI into academic writing has prompted widespread policy responses from journals and publishers. However, the effectiveness of these policies remains unclear. Here, we analyze 5,114 journals and over 5.2 million papers to evaluate the real-world impact of AI usage guidelines. We show that despite 70% of journals adopting AI policies (primarily requiring disclosure), researchers' use of AI writing tools has increased dramatically across disciplines, with no significant difference between journals with or without policies. Non-English-speaking countries, physical sciences, and high-OA journals exhibit the highest growth rates. Crucially, full-text analysis on 164k scientific publications reveals a striking transparency gap: Of the 75k papers published since 2023, only 76 (~0.1%) explicitly disclosed AI use. Our findings suggest that current policies have largely failed to promote transparency or restrain AI adoption. We urge a re-evaluation of ethical frameworks to foster responsible AI integration in science.

AI-Assisted Writing Is Growing Fastest Among Less Established Scientists in Non-English-Speaking Countries

The recent emergence of AI-assisted writing raises an important question: how is this new technology being adopted across the scientific community, and how does adoption vary across linguistic and professional contexts? We analyze over two million full-text biomedical publications from PubMed Central from 2021 to 2024 using a distribution-based framework to estimate AI-generated content. We found that, in biomedical publications, AI-generated content increased substantially after ChatGPT, with larger increases in publications from countries with lower English proficiency. Increases were also greater among scientists with fewer publications and citations, those at earlier career stages, and those at lower-ranked institutions. Prior AI research experience was associated with greater increases in AI-assisted writing, which were also modestly associated with greater increases in publication productivity. These findings show that AI-assisted writing is growing fastest among biomedical scientists who may have historically faced barriers, a pattern with potentially positive implications for equity in science.
