Thin on the left so far

Only 1 of the 8 outlets with a published leaning rating that ran this story are rated left.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

Elon Musk's social media platform X, formerly Twitter, failed to flag a significant majority of false claims concerning the U.S. midterm elections, a study by NewsGuard reported. The platform's crowdsourced verification system, Community Notes, tagged only 13 posts containing false election claims, despite these posts generating millions of interactions before the November 3 midterm elections. NewsGuard found that 93.1% of false claims related to the elections were not flagged by the system.

The falsehoods identified included allegations of election fraud and a claim by a conservative commentator that New York and California had made it illegal for voters to show their voter ID. Researchers have previously questioned the effectiveness of Community Notes in combating misinformation, noting that it works best on topics with broad consensus and can be influenced by partisan beliefs. X did not respond to requests for comment.

Disagreement on Musk's own flagged posts

CTV News reported that Elon Musk, who has 241.5 million followers on X, advanced at least four false claims related to the midterm elections, none of which carried Community Notes. None of the other reports mention whether Musk himself posted false claims or if they were flagged.

What the coverage left out

None of the right-rated digests mention that Elon Musk himself advanced at least four false claims related to the midterm elections, none of which carried Community Notes, as reported by CTV News. The unrated digest from El Economista also did not include this detail.

Questions about this coverage

How did the left and right cover NewsGuard: X Community Notes missed 93.1% of false US election claims?
Of the 8 outlets on this story carrying a published leaning rating, 13% are rated left, 49% are rated centre, 38% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 12. The sections above set out what each side emphasised, in its own terms.
Is NewsGuard: X Community Notes missed 93.1% of false US election claims left or right?
Too few of the outlets on this story carry a published leaning rating to say. 8 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
Is the coverage of NewsGuard: X Community Notes missed 93.1% of false US election claims biased?
NewsGuard: X Community Notes missed 93.1% of false US election claims is one event reported by 12 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
