I'll be giving a (virtual) flash talk at #CogSci2026 today (15:30 Rio time, 20:30 Paris time) on how argument evaluations from LLMs compare to human (intuitive and more deliberate) ones! 🤖💬 @cogscisociety.bsky.social joint work w/ @wimdeneys.bsky.social at @lapsyde.bsky.social @upcite.bsky.social

Feel free to drop by this afternoon ! #APS26BCN (Now with the correct hashtag 😅)
I'll be at #APS2026BCN presenting "The Price of Thought: Cost-Benefit Tradeoffs Shape Reasoning Engagement." W/ Talia Sander & @wimdeneys.bsky.social we put a price tag on thinking time to see how people value deliberation. Turns out: mostly, they won't pay -but that might be rational. Come say hi!👋

People and LLMs evaluate deliberative reasoning more favorably than intuitive thinking—even when both yield accurate results. This preference appears to be intuitive itself and has implications for how we assess others’ and AI advise. @wimdeneys.bsky.social www.nature.com/articles/s44...

Happy to share that my first paper is out in Thinking & Reasoning! 📄📢 With Aikaterini Voudouri, @boissinesther.bsky.social & @wimdeneys.bsky.social we show that deliberate reasoning helps not just to correct but also to justify intuitive judgments. 🔗Full paper: shorturl.at/JTeTi Quick thread below!
👀 Just out in Thinking & Reasoning with @boissinesther.bsky.social @mts-raoelison.bsky.social @wimdeneys.bsky.social Curious how intuitive reasoning develops through adolescence? 🔗 www.tandfonline.com/eprint/KFH5K... Quick summary👇
Had a great week at the 2025 Summer Institute on Bounded Rationality at @mpib-berlin.bsky.social. Super interesting talks & workshops on various aspects of decision-making and a great opportunity to discuss the latest work in the field! Many thanks to the organizers, speakers & participants!

New preprint: “Folk Thinking, Fast and Slow: Intuitive Preference for Deliberation in Humans and Machines” Pop culture often praises intuition (“Blink”, Steve Jobs). But do we really trust it? Across 13 studies, we find a strong intuitive preference for deliberation. tinyurl.com/8r54dmyn (1/6)

How does justification relate to performance on heuristics biases tests? @nicolasbeauvais.bsky.social and colleagues incorporated justification into both fast and slow conditions. I couldn't hear everything so I'll defer to Nicolas for answers to questions about the methods, results, conclusions.
