AI-Fabricated Citations In Over 2,800 Biomedical Journal Articles
A recent study published in The Lancet revealed a significant increase in AI-fabricated citations within biomedical journal articles. Researchers developed an AI-powered system to analyze over 2.4 million papers, identifying more than 4,000 fabricated references across 2,800 articles between 2023 and early 2026. This trend, particularly prevalent in review articles and potentially linked to LLM hallucinations, saw a more than 12-fold increase in fabricated citations per paper during the study period. AI
