The review was submitted earlier than Kent's piece but published four months after it appeared in the Guardian. The plagiarism went undetected until March 31, 2026, when scrutiny revealed the duplication. The gap between submission and publication, combined with Preston's admission about his AI workflow, suggests the tool accessed existing reviews through web search or retrieval-augmented generation without explicit instructions to avoid them.
The incident underscores a widening gap between newsroom adoption of AI for productivity and the safeguards necessary to prevent misconduct. While journalists at Fortune, Wired, and the Times itself have begun using AI tools openly and responsibly, Preston's case mirrors earlier failures like CNET's AI-generated errors. Reader surveys show demand for disclosure about AI use, yet trust drops sharply when AI involvement is revealed. For newsrooms, the lesson is clear: efficiency gains from agentic tools require robust policies, careful prompting, and human oversight to protect both credibility and legal exposure.
