[Alaska Media Bias Scorecard](https://communities.news/communities/alaska-news/neutrality) · one of 13 outlets scored # MatSu Sentinel Media Bias & Reporting Quality [MatSu Sentinel](https://matsusentinel.com) is one of 13 outlets on the Alaska Media Bias Scorecard. A panel of three AI models from three different companies, reading with every outlet name and byline removed, has scored 49 of its articles under rubric v0.4.0. Its partisan lean reads 0 (near-zero net lean) and its ideological lean 0.1 (near-zero net lean), with no partisan lean detected in 47 of 49 articles. Data as of 2026-10-23; the numbers move as the sample grows. **About this sample.** 49 articles from MatSu Sentinel's website, scored between 2026-09-29 and 2026-10-23, from its own news and opinion sections ([local](https://communities.news/communities/alaska-news/neutrality#term-local "An outlet's own journalism: its news, politics, business and opinion sections, classified by the same rule for every outlet. Wire stories, sports and syndicated lifestyle columns are excluded. Local means the outlet's own reporting, not stories set in Alaska, which the coverage map counts separately."): wire, sports and syndicated lifestyle are excluded, and a broadcaster is scored on its written web articles, not its broadcasts). Read by anthropic/claude-sonnet-5, openai/gpt-5.6-terra, google/gemini-3.8-flash, with outlet names and bylines removed; that blinding is partial, since style or subject can still hint at the source. The panel scores the text and does not fact-check it. [Full methodology](https://communities.news/communities/alaska-news/neutrality#methodology).

These describe the sampled articles, not every story MatSu Sentinel publishes. Labels such as [near-zero net lean](https://communities.news/communities/alaska-news/neutrality#term-nearzero "The label for a net lean whose absolute value is under 0.5; from 0.5 up to 1.5 the label is "leans", and 1.5 or more names the side outright. These are cutoffs for labeling, not statistical tests, so read the number beside the label: a -0.4 and a -0.5 differ by a tenth.") are cutoffs on the number beside them, not statistical tests. ## Its fingerprint Five lean axes on the same -3 to +3 scale every outlet is drawn on. The marker is the net lean; the pale band spans the average swing per article in both directions. \[Chart: MatSu Sentinel: lean fingerprint across five axes\] ## Where it sits among Alaska's outlets \[Chart: Every tracked outlet positioned by ideological lean, source independence, and publishing volume, each bubble labeled with its outlet name\] **MatSu Sentinel** Ideological lean +0.1 · independence 2.3 / 4 \~1.1 local articles/day · 49 scored **How to read this:** left and right is ideological tilt; up is source independence (official claims tested rather than relayed). Bubble size is local articles per day, publishing volume rather than audience reach. Dashed outlines mark the known-lean control and the out-of-market reference; the moose marks our own newsroom.
