A great preprint is out! It was also super fun collaborating with science museums!! Huge thanks to Humboldt Forum and Miraikan too!!

New preprint led by @lucasmolleman.bsky.social investigates social information use across the human lifespan. Testing >40,000 participants aged 6-80 in museums in Berlin and Japan. psyarxiv.com/hec96

The next ACE seminar will be happening tomorrow📣 We are excited to have Pat Savage talking about the evolution of music and language! @patrickesavage.bsky.social (Note: the actual time slot is 2-3pm, 30-min shorter this time)

I wrote a tiny LaTeX package that creates a wordcount environment. You can use it to auto-print word counts, when paring down text to meet limits. For example: \begin{wordcount}{\abstractcount} This is my abstract. \end{wordcount} \textbf{Word count:} \abstractcount % prints 4 Source code below…

Hey EU folks if you are enjoying #eurovision you can replace your scoresheet with this scientific platform! You can contribute to our understanding of how culture evolves!

My team, Minsu Park and I just launched 12points.science. It’s a citizen science platform and app where you can rate, rank, and comment on Eurovision entries with your friends. There is a deeper research goal behind the glitter 🎤🧪 #Eurovision #OpenData

Contribute to research on cross-cultural variation in taste, voting, decision-making! it's #Eurovision #ESC final night and my queer half-Austrian dual-scientist household is excited to replace homemade scorecards with this #CitizenScience 🧪 rating app 12points.science ✨🪩❤️‍🔥👯❤️‍🔥🪩✨ @eurovision.tv

My ultimate dream project is to bring the criminally underrated works of Shinji Wada to English readers. An outlier in shojo, his works are full of gritty action, intrigue, kick-ass female leads, and side characters with so much depth some had several short manga worth of backstory🧵

🚨 Cultural evolution paper alert

Finished the latest in @aptshadow.bsky.social 's "Children of..." series over the weekend. Spectacular exploration of interdependence in ecology, "bottom-up" and "top-down" intelligent design, cultural evolution, and the complex inner life of a stomatopod. Give it a read!

some Bayesian cognitive modeling students are having trouble seeing the industry-relevance of the methods (my worked out examples are research based, since it's what I do). Tips for good industry examples? @ajordannafa.com @natehaines.bsky.social @rmcelreath.bsky.social @avehtari.bsky.social

Nice coincidence that a big study of cooperation decline in microfinance in Sierra Leone has appeared in Nature just after our meta-analysis. Hints that partner choice, reciprocity and punishment were involved, but sadly no explicit focus on non-proximate explanations www.nature.com/articles/s41...

Real-world data reveal that cooperation continually falls and rebounds. Motivation to cooperate must therefore be actively renewed rather than assumed to sustain itself go.nature.com/4tvFx7I

Things I thought I’d never say - here’s a new manuscript of cockroach and rat collective intelligence. We argue group-level intelligence can emerge from very different mechanisms—from simple local rules to socially mediated cooperation and learning: royalsocietypublishing.org/rstb/article...

Next year in Zurich 😊 🏔️🇨🇭 #ehbea2027 will be held 29 March to 2 April. Website and Bluesky account are already set up (love the logo ❤️) @ehbea2027.bsky.social www.ehbea2027.com

Phil Trans Roy Soc B theme issue ‘The evolution of collective intelligence’ is out! royalsocietypublishing.org/rstb/issue/3...

Last day of conference! We had a wonderful day with amazing talks from @nicolewalasek.bsky.social and @nakedprimate.bsky.social ! We also had our Annual General Meeting, with a big round of applause for the Organising Committee and last words from @rebeccasear.bsky.social as president. #ehbea2026

Worried about the pricy hotels in Zurich? No problem, “couch surfing” is there! #ehbea2027 Can I camp somewhere beside the Zurichsee?? ⛺️

Awesome plenary from @nakedprimate.bsky.social at #ehbea2026, about gestures and storytelling, which started with a dawn drive in Chad and ended with a Douglas Adams quote perfectly encapsulating the process of science

No, they really haven't. Calling spectral peaks vowels is as inane as saying that because my washing up gloves are also yellow, they have the same nutritional content as a banana. Zero evidence of vowel-like function. It's pure clickbait, and a new low in irresponsible claims from this group 🙄🐳🦑🧪

Great talk by @jingyux.bsky.social bringing the collective behaviour vibe to #ehbea2026 ! Stay tuned to her beky account for the upcoming preprints on her talk on social learning + social networks

Great talk by @babeheim.bsky.social at @ehbea2026.bsky.social on the cultural evolution of strategies in the game Go, including the convergence of AI on established strategies. #ehbea2026

📢 New preprint📜 out 🚨: "Biased processing of multiple outcomes in human reinforcement learning: evidence from computational modeling and eye-tracking" How do we integrate multiple outcomes that stem for a single decision? 🔗 osf.io/preprints/ps... Too lazy to read? I made a summary of the thread👇

New preprint (by Vandendriessche et al.) In everyday life, choices often lead to multiple simultaneous outcomes — some positive, some negative. Yet most reinforcement learning research has focused on situations where each choice produces only a single outcome 1/5 osf.io/preprints/ps...

Arrived in Leiden

🚨Last week to apply for a 3 year postdoc with me and @dominikdeffner.bsky.social, embedded in theadaptivemind-excellencecluster.de Focus is on developing innovative experiments and computational models to understand social & cultural learning. Deadline is March 30th 👉 hmc-lab.com/SocialLearni...

Vincent Laudet dives (literally) into the Okinawan ocean to study the mystery of anemonefish megacolonies.

Henri @henrivdd.bsky.social shows how consensus making shapes and is shaped by reinforcement learning of group members

Gerald Pao pointed out causations can come without corrections and that’s why we need to dive into the data geometry #HIVE2026

Katja Sangati gives a nice overview of collective behaviour phenomena any why modelling is key

The first OIST-RIKEN HIVE meeting just kicked off!

Happy to announce I started a postdoc with @watarutoyokawa.bsky.social at RIKEN-CBS! 🎉 I'm absolutely thrilled to be here (and not just because it's easy to find great waterfalls) For this position, I'm broadening my research to include more interactive and naturalistic social learning settings 🧠

It’s today!
