A Lancet letter led by Columbia University's Maxim Topaz found 2,810 papers contained 4,406 fake citations among 97.1 million references checked.
The sharpest rise began in mid-2024 alongside wider AI-writing use, and more than 98% of affected papers had seen no publisher action by February.
Researchers and editors disagree on when fake citations warrant retraction, while publishers are urged to add automated screening, especially for review articles, which showed 57% higher fabrication rates.
As AI floods science with fake citations, is the 'publish-or-perish' academic model on the verge of collapse?
With AI fabricating facts in both science and government, how can the public still trust any expert advice?
The 10x Surge in Fake Academic Citations by 2025: Unraveling the AI-Driven Crisis
Overview
In 2025, academic publications saw a dramatic surge in fake citations, fueled by flawed AI tools that confidently generate fabricated references and intense academic pressure to publish frequently. This toxic mix led researchers to unknowingly include fake citations, while paper mills profited by selling fraudulent papers and citations. The crisis caused billions in wasted research resources and eroded public trust in science. AI models trained on polluted literature now perpetuate this problem, creating a vicious cycle of growing fraud. Traditional peer review and detection tools struggle to keep up, highlighting the urgent need for mandatory verification, provenance tracking, education, policy reform, and broad collaboration to restore research integrity.
