1/ How effective is X’s Community Notes at addressing misinformation? @sciencefeedback data team investigated moderation during the 2024 EU elections using data from the EFCSN. Here’s what we found:
2/ Community Notes, launched as "Birdwatch" in 2021 and rebranded in 2023, relies on crowd-sourced input. Notes require cross-partisan agreement before publication, but this limits scalability and response to viral misinformation.
3/ Out of 894 tweets flagged by professional fact-checkers:
▪︎ 67.2% had no visible moderation.
▪︎ Only 11.3% featured Community Notes or warning labels.
▪︎ 19.5% were deleted.
Community Notes coverage varies dramatically across countries. For example:
▪︎ Denmark: 2.44 Notes per 1,000 users
▪︎ Hungary: 0.08 Notes per 1,000 users
These gaps highlight the system’s uneven implementation.
4/ While X promotes Community Notes as a crowd-sourced alternative to professional fact-checking, our findings reveal that its limited reach and uneven application across EU countries undermine its ability to manage misinformation effectively at a scale, especially during critical events like elections.
