What happened

Peter Vandermeersch, a fellow at Mediahuis, used AI tools including ChatGPT, Perplexity and Google's NotebookLM to summarise reports for his blog posts but did not verify whether the quotes generated by these tools were accurate before publishing them.

An investigation by NRC, a Dutch newspaper in the Mediahuis group where Vandermeersch had previously been editor-in-chief, found that 15 of his 53 blog posts contained quotes that could not be verified in the original sources he cited. Seven individuals confirmed they had not made the statements attributed to them.

Reported impact

Eight of Vandermeersch's articles were removed from the independent.ie website and app. Vandermeersch was suspended from his role as fellow.

Index analysis

Vandermeersch acknowledged that he 'fell into the trap of hallucinations' and 'wrongly put words into people's mouths' when using the AI tools without human verification. He stated he should have presented the AI-generated text as paraphrases rather than direct quotes.

Governance controls

Mediahuis group chief executive Gert Ysebaert stated that the company applies strict rules for AI use requiring diligence, human oversight and transparency. Ysebaert said the principles were not followed in this case and ran counter to the company's standards.
