I’m in lovely Montréal attending #FAccT2026 this week! 🍁⚜️ I’ll be presenting our paper on how people use evidence and explanations when they make decisions about LLM fact-checks 🔎 Check out the paper here, or say hi during the conference! dl.acm.org/doi/10.1145/...

We are hiring a postdoc for a project on emergent deception in human-AI interaction, combining behavioural psychology, economics, and machine learning. Supervised by Ingo Zettler and me at @copenlu.bsky.social & @cphsodas.bsky.social , Copenhagen. ⏰Deadline: 5/July/2026 📅Start: 1/10/2026 Link 👇

CopeNLU had a blast attending @euripsconf.bsky.social last week -- thanks so much to the organisers (Søren Hauberg, @serge.belongie.com, Bernhard Schölkopf, Aasa Feragen) for putting this together! Non-scientific highlights were clearly the banquet dinner & the specially brewed EurIPA.

🚨New pre-print 🚨 News articles often convey different things in text vs. image. Recent work in computational framing analysis has analysed the article text but the corresponding images in those articles have been overlooked. We propose multi-modal framing analysis of news: arxiv.org/abs/2503.20960
