More @culturalevolsoc.bsky.social conference talks! @babeheim.bsky.social on norm psychology, and in particular escalator standing norms in Japan

it's crazy that I now have a real life mana bar and it's the codex weekly usage meter.

Cherry trees in Kyoto. Not a subtle signal.

I recently learned about the Great Giana Sisters, the German video game answer to the Super Mario Brothers. Absolutely epic box art

Not a secret anymore! I am extremely proud and happy to present you the EVApeCognition Dataset, out now in Scientific Data. Over the last 5 years we have assembled and standardized data from 150 studies on great ape cognition from the WKPRC in the Leipzig Zoo! www.nature.com/articles/s41...

Absolutely incredible. NASA Astronaut Reid Wiseman, who commanded Artemis II, took this footage from the far side of the Moon with his iPhone. Watch with sound on.

New preprint with Rafael Leite, Sandro Reia and Paulo Campos Cumulative Cultural Evolution in Structured Populations www.biorxiv.org/content/10.6... In which we take an old model of cumulative cultural evolution of mine and see what happens if you add social networks

@babeheim.bsky.social, Waterhouse and I describe how widespread vocal mimicry is in corvids and what might drive its evolution. Evidence is presented in 39 corvid species (30%). Using modelling approaches, we show that mimicry is likely underestimated (9/15) link.springer.com/article/10.1...

🧵 Very proud our special collection on vocal communication in corvids in Animal Cognition (@springernature.com) is now fully published! 🐦 Huge thanks to all collaborators and contributors who made this possible! (1/15) link.springer.com/collections/...

Excellent talk on machine-human interactions, cooperation and learning by @iyadrahwan.bsky.social, presented at @ehbea2026.bsky.social. #ehbea2026 #culturalevolution

Fantastic example of intellectual humility from @drsarahmyers at #ehbea2026, re-evaluating a previously published paper of her own using more robust methods. Advice to the audience: “be more reflective”

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

I'm a data scientist @ourworldindata.org and I need help from a botanist or someone local to Kyoto, Japan! 🌸 We present one of the world’s longest climate records: 1,200 years of peak cherry blossom dates in Kyoto. The researcher who maintained it, Prof. Yasuyuki Aono, sadly passed away last year.

I'm hiring! 📢 Fully funded 4-year PhD position in Language Evolution using Communication Games at @mpi-nl.bsky.social. Come work with me on how different social pressures shape the evolution of new communication systems in the lab! Deadline for application is May 18th! share.google/fGTKbFS4v4Gb...

In a sane world, he'd be removed from office for this

The horse op-ed is an instant classic. I can't tell you how much joy this piece gives me. It should be taught in every introductory writing class in no small part because the horse arguments are so compelling. "I have noticed that human children get to eat cake. But I am bigger than the children."

Easy for Batman to say, he's a billionaire

Easter EP As AI agents get smarter, are we entering a golden age of hypercreativity? Or are we entering an age of homogenised culture where we all just recycle the same AI-generated ideas? @adigitaltanay.bsky.social & Jay explore this and much more with @babeheim.bsky.social youtu.be/coQnyaEw50s

If I were on a mission whose computer system required me to deal with Microsoft Outlook in space, I’d give up and go back to the slide rule

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

Commentaries on SCORE papers from @asanchez-tojar.bsky.social, Jelte Wicherts, and @robbwiller.bsky.social www.nature.com/articles/d41...

🔥🔥🔥

This is a great idea. I'd rather the norm in science to be wrong for the right reasons, than right for the wrong ones.

I picked this up from a 7-11 in 2003 and think about it often

Come work with us! And get in touch with any questions you might have about the position, our labs or living/working in Germany #PostdocWanted

It's hard to communicate to non-USAians how deeply sad and upsetting today's actions by our government are. They were wrong in 2003 in Iraq, and they are wrong today. History will judge us all for this barbarity

Last day of February in Germany be like

a gpt in a sublime 200 lines of pure Python — it is all there. Incredible for teaching students (and yourself) karpathy.github.io/2026/02/12/m...

Just discovered an insane new form of co-intelligence where you briefly share the mind of a great thinker in history and then a portion of their mind travels in yours for the rest of your life. Calling it a "book."

One of the few downsides about living in Leipzig (and eastern Europe more generally) is the absolutely atrocious air quality. Definitely regretting biking into work today....

I just read the declaration that Kira Kelley asked J. Blackwell to consider. This immigrant describes being -unlawfully arrested -taken from one overcrowded & filthy prison to another over 19 days -held incommunicado & ICE never telling him a court ordered his release He describes an American gulag

as I'm revising my course materials, I keep stumbling upon cool @mc-stan.org developments. Current favorites: 1. your model has funnels and you exhausted reparametrization ideas: metric = "dense_e" makes your HMC learn about covariance btw parameters. Sloooow, but effective! 1/

My dog's post-surgery face is a pretty good signifier of the state of my household right now

Today at the Leipzig Hauptbahnhof - a novel solution to the trolley problem

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉 We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟 Link: www.science.org/doi/10.1126/... (contact me for open access)

timeline is terrible, time for cozy office vibes

New blog post!!🚨 Michael Chimento gives an overview of the new R package STbayes, designed for creating, fitting and understanding Bayesian models of social transmission 🌍 🧪 Read the blog here 👇

May be of interest to the reproducibility folks: New tutorial on computational reproducibility for simulation studies just dropped! felipelfv.github.io/Why-risk-it-... by @felipefv.bsky.social, Jason Geller & @brodriguesco.bsky.social

Some trivia to keep me off the newsfeeds - I remember when @rmcelreath.bsky.social's stats course was just called "Statistical Thinking"

Voting NO on the DHS funding bill is the bare minimum. Backing Kristi Noem’s impeachment is the bare minimum. Holding law-breaking ICE agents legally accountable is the bare minimum. ICE is beyond reform. Abolish it.

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

I noticed my BEC talk is up on youtube: "Planck's Principle, Price's Theorem and the Forces of Cultural Evolution".

A colleague at MPI asked how to get better at math. My vote is Thompson and Gardner's classic *Calculus Made Easy* (originally published in 1910!) I've uploaded my own (almost complete) worked problem sets from this classic book. A few thoughts.../

"I no longer feel an obligation to think purely of Peace"

Beautiful business research people: The Leibniz Information Centre for Economics has created an accessible introduction to Open Science that you can download in both English and German here: expedition-open-science.org You can even order the German print version for free!

Our new paper in Hunter-Gatherer Research! We explored women’s decision-making power within households in two subsistence communities with different gender norms (BaYaka foragers & Bandongo fisher-farmers) in the Congolese rainforest ✨ www.liverpooluniversitypress.co.uk/doi/abs/10.3...
