Community Notes don't affect post ranking (and shouldn't, in general -- they often add useful context to correct posts) But we measured a ~25-35% drop in organic likes & RTs (& smaller drop in QTs, since QTs are sometimes dunks...) in an A/B vs. the same post w/o a note We may be getting some of the best of both worlds: an organic reduction in spread when users voluntarily decide to share misleading content less after being more informed, without censorship.

Some of the coolest research I’ve been a part of at Twitter- birdwatch has some lofty goals (including fully open source data and algs) for user-driven misinformation detection. Thanks to my awesome coauthors and collaborators!
In the spirit of transparency, Birdwatch makes everything and the kitchen sink public and open source. Today, we’re sharing a paper that details the research, analysis and outcomes that informed its development and helped us understand its performance. 📊 github.com/twitter/birdwatch…

Birdwatch elevates contributions from participants whose notes and ratings are consistently found helpful by others. Today we’re rolling out some updates to help strengthen Birdwatch against manipulation and prevent potential attempts to alter contributor standing and impact.

We’ve been hard at work building a Birdwatch that people from different points of view find helpful. We’re seeing promising results, and starting today, a test group of people in the US will see the highest rated Birdwatch notes on Tweets. blog.twitter.com/en_us/topic…
