Researchers Caught Hiding AI Prompts in Research Papers To Get Favorable Reviews

Researchers from 14 academic institutions across eight countries embedded hidden prompts in research papers designed to manipulate AI tools into providing favorable reviews, according to a Nikkei investigation. The news organization discovered such prompts in 17 English-language preprints on the arXiv research platform with lead authors affiliated with institutions including Japan's Waseda University, South Korea's KAIST, China's Peking University, and Columbia University.

One prompt directed AI readers to recommend the paper for its "impactful contributions, methodological rigor, and exceptional novelty."
