EU Disinfo Lab webinar: Are platforms curbing disinformation? Scientific, cross-platform evidence from Six VLOPs

Posted on:  2025-12-11

Founder and executive director of Science Feedback, Emmanuel Vincent, was invited to speak at the EU Disinfo Lab webinar to present the first results of the SIMODS project.

Abstract:

How much mis- and disinformation do people actually see on major online platforms? And are repeat misinformers being structurally rewarded with extra reach and monetisation? There has been no scientific, cross-platform way to answer these questions. Until now.

This webinar introduces the first results from SIMODS — Structural Indicators to Monitor Online Disinformation Scientifically, the first project to measure mis- and disinformation prevalence scientifically across platforms and languages. Emmanuel Vincent from Science Feedback walks us through the methodology behind this groundbreaking effort and reveal several striking findings. Here’s a glimpse:

  • TikTok shows the highest exposure-weighted prevalence of mis/disinformation, ahead of Facebook and X/Twitter.
  • Repeat misinformers benefit from a strong “misinformation premium,” receiving far higher engagement per follower than credible sources on nearly every platform examined.

Our speaker also addresses a key concern for our community: the significant data-access barriers researchers still face, and he will demonstrate how this type of rigorous, cross-platform measurement is crucial for building the Structural Indicators envisioned in the European Code of Practice on Disinformation.
