Researchers from the University of Tubingen and Northwestern University have identified linguistic markers that suggest AI-assisted writing, specifically analyzing 14 million PubMed paper abstracts from 2010 to 2024. They discovered that terms like “delves,” “showcasing,” “underscores,” “comprehensive,” “crucial,” “intricate,” and “pivotal” spiked in usage after generative AI tools like ChatGPT became available. Although these words alone don’t confirm AI use, their presence, especially in combination, raises suspicion.
Implications for Detection and Usage
The study indicates that up to 10% of recent papers may involve AI assistance, with a higher likelihood in non-native English-speaking countries like China and South Korea. As detection methods improve, AI tools might also evolve to avoid detection, potentially necessitating advanced strategies to distinguish AI-generated text.
Practical Takeaway for Professionals
Rather than focusing on specific “marker words” as definitive proof of AI writing, it’s more effective to assess the overall quality of the text. Questions about accuracy, relevance, audience engagement, and argumentative strength remain crucial. The presence of sophisticated vocabulary might indicate AI use but should not overshadow the importance of clear, impactful communication.
