How do CNN, MSNBC, and Fox News rank on recent independent media accuracy audits?

1. A snapshot from network scorecards: who’s being checked and how

PolitiFact’s PunditFact network scorecards measure pundit claims over time and show measurable differences in how often networks’ on‑air personalities are rated false or worse; earlier reporting noted that MSNBC and CNN improved slightly while Fox moved in the opposite direction on those Truth‑O‑Meter scorecards ^{[1] [2]}. Those audits focus on pundit and commentator claims rather than every newsroom story, so they reflect the accuracy of on‑air commentary as much as straight reporting ^[1].

2. Media Bias/Fact Check: ratings that combine bias and factuality

Media Bias/Fact Check assigns both a directional bias and a factual rating: it classifies Fox News as right‑biased and “Questionable” with a Low factual rating citing promotion of conspiracies and repeated false claims, while it lists CNN as moderately left‑center biased and rates its reporting as Mostly Factual ^{[3] [4]}. Those composite ratings mix editorial posture, correction history and specific failed fact‑checks into a single label ^{[3] [4]}.

3. Research studies and content audits: coverage and sourcing matter

Academic and NGO studies cited in reporting show differences in sourcing and topical accuracy: a Union of Concerned Scientists review of climate coverage found Fox’s accuracy substantially behind CNN and MSNBC in that topic, and social network analyses of sourcing show CNN often using a narrower, more vertical source network while MSNBC and Fox exhibited more fragmented source networks ^{[5] [6]}. Those findings signal that “accuracy” audits sometimes hinge on beat, topic and sourcing practices, not just headline error counts ^{[5] [6]}.

4. Ratings, trust and the political lens on accuracy

Public trust and perceived accuracy are highly polarized: surveys and trust polls show CNN and MSNBC are trusted much more by Democrats and Fox much more by Republicans, and Americans often see the same outlets as biased or inaccurate depending on party ^{[7] [8]}. These perception gaps mean independent audits can be weaponized politically even when their methods are transparent ^{[7] [8]}.

5. Major controversies and downstream audits: why context matters

High‑profile controversies feed audits and re‑ratings: recent reporting about Fox’s post‑2020 election coverage and internal documents released in litigation have become inputs for scrutiny and external assessments ^[9]. Available sources do not mention a single, unified “recent independent media accuracy audit” that ranks all three networks side‑by‑side in one, definitive study; rather, multiple audits and scorecards evaluate different elements ^{[1] [2] [3]}.

6. Limitations, competing interpretations and what audits omit

Each source uses different methods and scopes: PunditFact checks on‑air claims, Media Bias/Fact Check combines editorial tilt with fact‑check histories, academic audits examine sourcing or topic‑specific accuracy ^{[1] [2] [6] [5] [3] [4]}. That means rankings can diverge: a network may score poorly on pundit claims yet still produce largely factual beat reporting, or score well on topical accuracy while drawing criticism for opinion programming ^{[1] [3] [4]}.

7. What readers should take away

Independent audits consistently show differences: Fox faces more citations for false or questionable claims in multiple audits and has a lower factual rating in Media Bias/Fact Check, while CNN and MSNBC tend to fare better on some academic and fact‑check metrics though both carry partisan perceptions ^{[3] [2] [5] [4]}. Evaluate audits by their method: ask whether they check pundit commentary, straight reporting, topic samples, or sourcing networks before accepting a network “ranking” as definitive ^{[1] [2] [6]}.

If you want, I can pull together the specific PunditFact tallies and recent Media Bias/Fact Check entries side‑by‑side so you can compare their methods and numeric counts directly ^{[1] [2] [3] [4]}.
