Can we entrust the moderation of platforms to their users? Pedro Ramaciotti's analysis on Conférence

In an article published on Conférence, Pedro Ramaciotti discusses the findings of a study by the médialab, cited by Meta's Oversight Board, which highlights the limitations of algorithmic and participatory moderation systems in highly polarized political contexts.

Post

Participatory moderation systems, such as Community Notes, are increasingly being considered by platforms as a way to combat misinformation.

In this context, a study conducted by Pedro Ramaciotti Morales (researcher in computational social sciences at the Sciences Po médialab and at the CNRS) and Paul Bouchaud (postdoctoral researcher in computational social sciences at the and associated researcher at the médialab).

Cited by Meta’s Oversight Board in a decision published in March 2026, this research shows that systems based on user consensus struggle to moderate the most polarizing content, particularly during election periods. Conducted in 13 countries, it highlights the limitations of these systems when deployed in highly polarized political contexts.
