Au printemps, l'équipe de Découverte de @info.radio-canada.ca a suivi l'équipe de l'OEM pour mieux comprendre notre projet de surveillance des élections fédérales canadiennes de 2025. Voici le résultat de leur travail : tinyurl.com/n3tvcjn9
Réseaux sociaux et démocratie : bruit, opacité et risques
À moins d'augmenter l'encadrement des plateformes, les tentatives de manipulation politique pourraient avoir le dessus sur notre capacité à les détecter.

Glad to have contributed to this report on the information ecosystem during the 2025 Canadian election.
It highlights key challenges and potential actions to protect our elections amid GenAI-powered disinformation, political segmentation, and reduced news visibility on social media platforms.

Over 25% of Canadians are being exposed to more sophisticated and more politically polarizing fake content. These ads don’t just defraud individuals—they risk undermining trust in journalism and the democratic process, spreading misleading political content at a critical time ⚠️

Another thing bothering me about the Zuckerberg statement -- the assertion that fact-checkers have “destroyed more trust than they created." FCers are obviously imperfect and have made mistakes, but most of what people hear about them is ax-grinding by conservative elites, not fair-minded critiques
