Democracies are vulnerable to misinformation. Prevailing interventions emphasize truth detection. L. Geay, @carocharp.bsky.social and I argue we ought to strengthen people’s ability to estimate claims plausibility and to calibrate their confidence under uncertainty. www.nature.com/articles/s44...

Been experimenting with AI agent systems lately (smolagents, llamaindex, langgraph, crewAI). The ecosystem is getting much more mature, tools for easy implementation are there (massive improvements over 2023 LangChain/Auto-GPT), ability to run python is insane.

Comment la confiance en soi nous expose à la #désinformation. C’est la conclusion que tirent les chercheurs Jean-Claude Dreher et @guigonv.bsky.social. Pour la #Semainedelapresse, pensons contre nous et vérifions si nos certitudes ne sont pas écrans de fumée. www.ouest-france.fr/leditionduso...

After over 10 years of barely using Twitter, I’m moving to Bluesky! Looking forward to sharing ideas, connecting with others, and seeing where this platform takes me. I’ll mostly post about research, science communication, et tout ce qui pique ma curiosité. À bientôt!
