Community Notes
Community Notes is X's crowdsourced fact-checking feature that lets approved contributors attach corrective context to potentially misleading posts, publishing a note only when raters from differing viewpoints agree it is helpful.
The mechanism is what makes Community Notes unusual. A proposed note does not go public just because it gets upvotes. X uses a bridging algorithm that looks for agreement across people who have historically rated things differently, so a note only appears when contributors who usually disagree both find it helpful. The intent is to make one-sided or partisan notes fail to publish, leaving mostly the context a broad range of readers accepts.
When a note is published, it shows beneath the post with a source link, and it can appear on anyone's content including large accounts and advertisers. Notes are slow by design, since the cross-viewpoint agreement takes time to form, so a fast-spreading false claim may travel widely before a note attaches. The system supplements rather than replaces other moderation, and its coverage depends on contributors choosing to write about a given post.
For anyone posting, the practical takeaway is simple: a note is a public correction on your own post, and it sticks. Claims that are easy to check and easy to get wrong are the ones that draw notes. Sourcing a number or softening an overstated claim before you post is cheaper than being annotated after it spreads.
