Apply for funding to work with me and Gord at Cornell!

Would love to read more. Is there a full paper ? Or full version of the poster ? Thx

3 months into Meta’s pivot to Community Notes, the company has yet to share any data about its crowdsourced moderation feature.

With help from three @indicator.media readers in the pilot, I tried to piece together how it’s going:

🚨In PNAS🚨
The right often accuses fact-checkers of political bias
But we analyzed Community Notes on Musk's X and found posts flagged as "misleading" are 2.3x more likely to be written by Reps than Dems!
The issue is Reps sharing misinformation, not fact-checker bias...

— We find a real, measurable partisan gap in misinformation sharing : even a “crowdsourced,” supposedly neutral system ends up flagging more Republican posts
— This challenges arguments that fact-checkers should be dismissed on the grounds that they’re too biased.

We analyzed every English Community Note on X over 1.5 years. In Community Notes:
— Users from across the political spectrum propose and rate notes
— Notes are only published when there is agreement between people who typically disagree (via X’s “bridging algorithm”)

💡 Why is this important?
Many past studies have found that Republicans share more misinformation. But critics argue those findings could be driven by :
— Bias in how fact-checkers or academics define misinformation
— Bias in which news stories researchers choose to study

🚨 New in PNAS 🚨

Posts by Republicans are 2.3 times more likely to be flagged as misleading than those by Democrats on X's Community Notes. A 🧵

For more of my group's work on misinformation, check out this doc: docs.google.com/document/d/1...

We examine all English notes 1/23-6/24. More notes are proposed on tweets written by Reps than Dems. The partisan diff is MUCH bigger when restricting to "helpful" (ie ~unbiased) notes: 63% on Reps, 37% on Dems. The "vox populi" on X has spoken and concluded that Reps share more misinfo than Dems!

Accusations of bias against conservatives drove Musk to buy Twitter- then gut fact-checking and up Community Notes. This month, Zuckerberg did the same at Meta. But greater sanctioning of conservatives could just be the result of conservatives sharing more misinformation bsky.app/profile/dgra...

🚨New WP🚨
Remember Musk+Zuck+Trump+Jordan etc crying fact-checker bias b/c Reps were flagged more than Dems? We analyzed Community Notes on Musk's X and guess what: posts flagged as "misleading" are 67% more likely to be written by Reps! The issue is Reps, not fact-checkers...

🚨OpEd+data: Meta is out of step with public opinion🚨
Zuck cut moderation b/c he said people no longer want it. But he's wrong!
We polled 1k Americans and most people, including majority of Reps:
i) want content moderation
ii) don't want Community Notes w/o fact-checkers
