Our Report: A new study reveals that at least 10% of recent biomedical research abstracts show signs of AI assistance, highlighting the significant impact of large language models (LLMs) like ChatGPT on academic writing.
Key Points:
Researchers analyzed over 14M PubMed abstracts from 2010 to 2024, focusing on changes in writing style and vocabulary.
Results showed a substantial rise in "excess words" in 2024, coinciding with ChatGPT's widespread availability, surpassing vocabulary changes observed during the pandemic.
LLM usage estimates varied across disciplines, with 20% in computation, 6% in Nature/Science/Cell, and up to 35% for computation papers from China.
Why you should care: AI is transforming academic writing, challenging our traditional notions of research authenticity and authorship. As AI writing tools become more prevalent in academia, researchers, institutions, and publishers must consider the implications for originality, authorship, and the peer review process.
