Methodology · Bias Scoring
Every article on Updat3 comes from a real outlet with a real editorial lean. We don't hide that — we show it. Here's exactly how the scoring works.
Each outlet has a lean score from −1.0 (hard left) to +1.0 (hard right), with 0.0 representing wire-service neutrality (Reuters, AP, AFP). Scores are based on AllSides, Ad Fontes Media, and Media Bias/Fact Check research, cross-referenced against editorial pattern analysis.
For international state media (RT, Xinhua, PressTV etc.), the score reflects editorial independence from the funding government rather than a domestic left/right axis.
We currently map over 150 outlets. Here is a representative sample:
Outlets not in our map default to 0.0 (unrated, not neutral). We expand the map regularly.
When multiple articles cover the same story, we average their outlet scores to produce a single spectrum position for that story — the needle on the bar you see on each story page.
Example calculation
Reuters 0.0 + Fox News +0.8 + The Guardian −0.5
= (0.0 + 0.8 − 0.5) ÷ 3 = +0.10 → slightly right of center
A story covered only by right-leaning outlets does not mean the event is false — it means our current coverage of it skews right. More sources improve accuracy.
Sources are grouped into three buckets based on their lean score:
Left
score below −0.2
Center
−0.2 to +0.2
Right
score above +0.2
If a story's sources span more than 0.5 on the scale — at least one clearly left-leaning and one clearly right-leaning outlet — we flag it as having diverse coverage. This is a positive signal.
When all sources cluster on one side of the spectrum, the story summary may reflect the framing assumptions of that side. We aim to add sources from the other side over time.
