A new AllSides analysis confirms what many have long suspected: the major news aggregators serving tens of millions of Americans are not neutral pipes. They are editorial gatekeepers — and they consistently tilt left.
By Michael Phillips | Riptide Analysis
There is a word for a system that presents itself as neutral while quietly advancing a predetermined editorial outcome: propaganda. That word is too strong for what AllSides documented in its newly released 2026 news aggregator bias analysis — but it is not as far off as the platforms would like you to believe.
AllSides, the nonpartisan media bias research organization that has rated outlet leanings since 2012, published updated aggregator ratings this month based on audits conducted between June and December 2025. The methodology: human reviewers examined non-personalized, human-curated sections of each platform’s news feed over two-week windows, then measured what share of content came from outlets AllSides rates as Left, Lean Left, Center, Lean Right, or Right.
The results were not subtle. Google News — the largest news aggregator in the world, serving an estimated 280 million users — sourced 73 percent of its homepage articles from left-rated outlets, and just one percent from the right. Apple News showed similar numbers: 50 percent from the left, two percent from the right. Bing News pulled 72 percent from left-leaning sources while offering just five percent from the right. Yahoo News drew 53 percent from the left, two percent from the right.
The Trend Line
A single data point can be dismissed as noise. A four-year trend line cannot. AllSides has been auditing aggregator bias since 2022, and the trajectory for Google News tells a clear story:
| Year | Left / Lean Left | Right / Lean Right | Center |
|---|---|---|---|
| 2022 | 61% | 3% | — |
| 2023 | 63% | 6% | — |
| 2024 | 66% | ~5% | — |
| 2025 | 73% | 1% | 25% |
Left-outlet representation on Google News has grown by 12 percentage points since 2022. Right-outlet representation has simultaneously collapsed — from six percent to one percent. That is not algorithmic drift. That is a sustained, worsening directional pattern across four consecutive years of measurement.
“By failing to provide a balanced newsfeed, the aggregators are effectively preventing Americans from considering multiple views and thinking independently.”
— Julie Mastrine, Director of Media Bias Ratings, AllSides
What the Platforms Say
Google disputed the findings, with a spokesperson calling the study “based on arbitrary ratings and a tiny two-week snapshot.” The response is a familiar one — and a strategically hollow one. AllSides has been using the same rigorous, multi-partisan methodology for years, combining editorial reviews by politically balanced expert panels with blind bias surveys of everyday Americans. The “tiny snapshot” objection ignores that four separate two-week windows across four years produced the same directional result, each time worse than the last.
More to the point: Google has never commissioned or published its own competing analysis. When you control the feed, you also control the ability to obscure what the feed contains. The absence of counter-evidence is not a defense.
Not Just Algorithms
One detail in the AllSides methodology matters more than it has received credit for. Reviewers specifically focused on sections of each platform’s feed that are not personalized — the human-curated “Top Stories” and homepage sections that every user sees, regardless of their individual settings. This is not a story about filter bubbles created by your own clicks. This is a story about what editors at Google, Apple, and Microsoft decided, deliberately, to put in front of every user who landed on their platforms.
Apple News’ “Top Stories” section — entirely human-curated by Apple’s editorial staff — showed 54 percent from the left and zero percent from the right. Zero. That is not an algorithm. That is a newsroom decision made by people who believed no right-leaning outlet deserved placement in the stories every Apple News user sees first.
AllSides assigned Google News a bias score of -1.62 on its Bias Meter (negative numbers indicating leftward bias, zero being perfect balance). Apple, Bing, and Yahoo all clustered around -1.55. Not a single major aggregator reviewed landed anywhere near zero.
The Stakes
AllSides’ Julie Mastrine was direct about the implications. The aggregators are “effectively preventing Americans from considering multiple views and thinking independently,” she said, adding that the scale — tens of millions of users — makes the impact “sinister and immeasurable.”
That is not hyperbole. When 280 million people use a single platform as their primary news gateway, and that platform sources nearly three-quarters of its content from one side of the political spectrum, the compounding effect on public perception is not theoretical. It is structural.
There are signs that the political environment is shifting around this issue. The White House and federal regulators have signaled interest in scrutinizing anti-conservative bias in tech. The AllSides data provides the kind of quantified, independently verified documentation that transforms that conversation from a political grievance into a policy argument. Whether that pressure produces change is an open question. But the platforms can no longer claim the data doesn’t exist.
One Note of Nuance
Not every platform is moving in the same direction. AllSides found that SmartNews and NewsBreak both improved enough to shift from Lean Left to Center ratings since 2023. NewsBreak, in particular, curated 21 percent of its content from right-leaning outlets — a larger share than any other aggregator in the analysis. That a smaller, less dominant platform managed to achieve greater balance than Google, Apple, Microsoft, and Yahoo is itself a data point worth sitting with.
Balance is not impossible. The dominant platforms have simply not prioritized it.
Bottom Line
The AllSides findings confirm a pattern that has been building for years and accelerating. The platforms that control the first page of news for most Americans are not neutral. They are not balanced. And the trend is not correcting — it is deepening. At some point, the question stops being whether this bias exists and starts being whether anyone in a position of authority intends to do anything about it.
That question does not yet have an answer.
Methodology note: AllSides conducted its 2025 news aggregator audits between June and December 2025 over two-week windows per platform, focusing exclusively on non-personalized, human-curated sections. Bias ratings reflect AllSides’ multi-partisan methodology combining editorial reviews and blind surveys of Americans across the political spectrum. Full data available at allsides.com.
