The 31 percent sourcing figure of the EBU audit counts responses and includes absent sources and is not a per-citation support rate
Rests on Journalists at 22 public media rated 31 percent of AI as…; BBC journalists rated over 45 percent of Gemini news res…
Falls whenThe EBU appendix or data release separates the three sub-categories and shows that unsupported claims alone account for nearly all of the 31 percent. Query: Q2 sub-codes in the EBU/BBC toolkit data.
Conclusion
The 31 percent of news responses with significant sourcing issues (Gemini 72, ChatGPT 24, Perplexity 15, Copilot 15 percent) is a share of responses rated by journalists on a criterion that covers unsupported claims, missing sources and incorrect sourcing claims together; it is not the share of citations that fail to support their claim, and for Gemini part of it is absent sourcing (42 percent of its responses gave no direct source in 2025, 26 percent gave none in December 2024).
Step
The EBU anchor contributes the definition of the category and the per-assistant spread; the BBC anchor contributes that the same criterion in the earlier round already mixed misattribution, unsupported claims and missing sources, and that missing sources were named as part of the cause for the assistant with the highest rate. The step narrows what the 31 percent can be cited for; it does not say the figure is wrong.
Breaking point
The EBU appendix or data release separates the three sub-categories and shows that unsupported claims alone account for nearly all of the 31 percent. Query: Q2 sub-codes in the EBU/BBC toolkit data.
Reflex
A third of AI news answers cite sources that do not back them up. Too coarse: the 31 percent also counts answers with no source at all.

The EBU parent defines the 31% as a response-level journalist rating that covers unsupported claims, no sources at all, and incorrect sourcing claims, with Gemini at 72% and 42% of its responses giving no direct source. The BBC parent shows the earlier Q2 already mixed misattribution, unsupported claims and missing sources, and names lack of sources as part of the cause for the assistant with the highest rate (26% of Gemini responses). The step only narrows what the 31% can be cited for.
