CONCLUSION: .*Clear partisan diff in misinfo sharing not due to political bias on the part of fact-checkers or academics.*Undercuts logic offered by Musk+Zuckerberg for eliminating fact-checkers.*Platforms should expect more Rep-sanctioning even when using Community Notes!.

We also address two poss confounds: *Is it just that more Reps are using X than Dems, throwing off base rates? No, it's the opposite *It is just that more Dems use CN? No, b/c rated-helpful notes + bridging algorithm require people from both sides rating the notes as helpful

Across all English notes 1/23-6/24: 1.5x more notes proposed on tweets written by Reps than Dems. The partisan diff is MUCH bigger when restricting to "helpful" (ie ~unbiased) notes: 70% on Reps, 30% on Dems. The "vox populi" has concluded that Reps share more misinfo than Dems!

Many studies find Reps do share more misinfo. But those studies could be biased in evaluating what is misinfo. So we analyze Community Notes, where users flag posts & X decides what is misleading using a “bridging algorithm” requiring agreement from users who typically disagree

Accusations of bias against Reps (eg Trump+others suspensions) drove @elonmusk to buy Twitter & gut fact-checking in favor of @CommunityNotes. @finkd did same at @Meta. But greater sanctioning of Reps could just be the result of Reps sharing more misinfo

🚨Out in Nature!🚨.Many (eg Trump JimJordan @elonmusk) have accused social media of anti-conservative bias.Is this accurate?.We test empirically - and it's more complicated than you might think: conservatives ARE suspended more, but also share more misinfo

Back to X just to post new PNAS paper for @elonmusk: we find @CommunityNotes flags 2.3x more Republicans than Democrats for misleading posts! The issue is Reps sharing misinformation, not fact-checker bias.

Today Meta announced it's getting rid of fact-checking to avoid bias. But is there actually evidence of anti-conservative bias? Not really - conservatives get suspended more but also share more low quality news (as judged by politically balanced crowds) ⏬.

This is a very cool paper by two of my fav people! Many studies have shown that more reflective people believe in God less. This paper shows that *changing* belief (in either direction) is ALSO associated with reflectiveness. Higher CRT = more willing to update beliefs.
