🍎 Do we really make 200 food decisions a day? In our latest podcast, Almudena Claassen @mpib-berlin.bsky.social reveals why that catchy number is flawed—and what really matters when studying eating habits. It's not about "magic numbers", but about context. www.youtube.com/watch?v=WuDO...

New semantic network paper in @plosone.org with @ruimata.bsky.social at @unibas.ch and @dirkwulff.bsky.social at @arc-mpib.bsky.social! We ran large-scale simulations to test how well common behavioral tasks measure a person's semantic network. doi.org/10.1371/jour...

New research out!🚨 In our new paper, we discuss how generative AI (GenAI) tools like ChatGPT can mediate confirmation bias in health information seeking. As people turn to these tools for health-related queries, new risks emerge. 🧵👇 nyaspubs.onlinelibrary.wiley.com/doi/10.1111/...

🚨We are seeking a student assistant to support web programming @mpib-berlin.bsky.social (Deadline: August 15) There are also opportunities to work with eye tracking, EEG, VR, 3D printing, and scientific computing. See the link for more details!👇 www.mpib-berlin.mpg.de/2110361/2025...

🤩IT'S A PREPRINT 😍 Adolescents' social sensitivity isn't a bad thing—it's adaptive! In our new study, led by amazing Andrea Gradassi @connectedmindslab.bsky.social, we show that teens learned to copy successful peers faster than adults in a new multiplayer exploration task. osf.io/preprints/os...

Nudging has shaped behavioral policy for years—but what are its downsides? In our latest episode, 𝐑𝐚𝐥𝐩𝐡 𝐇𝐞𝐫𝐭𝐰𝐢𝐠 makes the case for shifting from nudging to 𝐛𝐨𝐨𝐬𝐭𝐢𝐧𝐠—an alternative behavioral science approach that fosters people’s agency, self-control, and decision-making skills. tinyurl.com/3yvfwxc8

1/n 🆕📄: How do children learn to adapt to different environments when making repeated choices? And what do cognitive immaturity and probability matching have to do with it? Our new article explores how kids & adults differ in probability learning across statistical task structures: mpib.berlin/R3RFy

Very happy supervisor with the publication of Pietro Nickl's article on global trends in online headlines: www.nature.com/articles/s41...

🚨New paper: Chimpanzees explore just like us! 🐵🔍 Lou Haux @mpib-berlin.bsky.social shows that chimpanzees adapt their exploration strategies to changes in the environment—exploring more in unstable conditions. Now out in Nature Communications @naturecomms.bsky.social www.nature.com/articles/s41...

New episode of 𝐔𝐧𝐫𝐚𝐯𝐞𝐥𝐢𝐧𝐠 𝐁𝐞𝐡𝐚𝐯𝐢𝐨𝐫 is live!🎙️ In this episode, I'm joined by @simyciri.bsky.social as we dive into why teens engage in risky behaviors—not out of recklessness, but due to a complex mix of developmental, social, and environmental factors. tinyurl.com/bdcn2b4r

People in 26 countries prefer more control over their online environment

 In a conjoint study (N = 11,868), we explored preferences for regulating online environments by examining binary choices between different regulation scenarios. Preprint:https://osf.io/preprints/osf/haqu9

🥁 Exciting news: Our new article on repeated risky choices is out now! How do children and adults make repeated choices when they learn about probabilities from description (i.e., graphical representation)? Not as expected! 👀 Full text: mpib.berlin/PUMtN 1/n

🚨Next week's talk at ARC We cordially invite you to join the talk titled "Social foraging across species" by ARC's Ralf Kurvers (@ralfkurvers.bsky.social) 📅 19 Dec 11:00 (Local Time Germany) @arc-mpib.bsky.social or online See the link for details👇 www.mpib-berlin.mpg.de/events/40244...

Very happy to share that our work is now published in PNAS! 🎉 It's a systematic look into how demographic and psychological factors are associated with misinformation susceptibility. @arc-mpib.bsky.social Thread below and can be read in full here: www.pnas.org/doi/10.1073/...

🌟🤖📝 **Boosting human competences with interpretable and explainable artificial intelligence** How can AI *boost* human decision-making instead of replacing it? We talk about this in our new paper. doi.org/10.1037/dec0... #AI #XAI #InterpretableAI #IAI #boosting #competences 🧵👇

How to link theory and data in cultural evolution (and beyond)? We propose a computational workflow that starts from generative models of empirical phenomena and logically connects statistical estimates to both theory and real-world explanatory goals. Out now in PNAS: www.pnas.org/doi/10.1073/...

How does speed–accuracy trade-off shape pair decisions? Using cognitive models, we show that group accuracy depends on the faster (and more error-prone) members, but that members use social information adaptively. Preprint: osf.io/preprints/ps... w/ Alan Tump, Ralf Kurvers @arc-mpib.bsky.social
