New paper in TREE co-led w @jennakohles.bsky.social: We explore how resource variability shapes the value of social information for maximizing resource gain & minimizing variance. This eco-evolutionary lens helps us explain why collective sensing emerges in dynamic ecosystems! 🧪 tinyurl.com/2rurcry7

What does it mean for culture to “shape” cognition? In our new TiCS paper, @benjaminpitt.bsky.social & I offer a typology of four possible effects: culture can Privilege one cognitive process over others, Prune out disfavored ones, Produce new ones, or have no effect. www.cell.com/trends/cogni...

This is an outstanding book, especially for fathers(-to-be)!

Why do otherwise rational people disagree about the same evidence? Our new paper finds that group membership is a deeply rooted influence on how we form beliefs, leading even preschoolers to bias their evidential standards and form inaccurate beliefs. www.nature.com/articles/s41...

It's out: the first ever podcast interview with Richard B. Lee! 🥁 We discuss the 60 year legacy of Man the Hunter conference, including: The Original Affluent Society The Dawn of Everything The choice of the term "Man" in the conference name. Enjoy!

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/

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)

We're doing the final sprint, and I think we're able to send the PDF of the forthcoming Bayesian Workflow book to the publisher in the next two weeks (500+ pages), which would mean it would be published some time next year

Psychologists, what are your favorite (open) data sets for teaching multilevel modelling? I have a lot of observational examples, would love a therapy RCT with varying effects for therapists or some such.

It's out!! www.science.org/doi/10.1126/... Big thank you to my coauthors @small-schulz.bsky.social and @lorenzspreen.bsky.social, and to all participants who discussed 20 political issues over 4 weeks in 6 subreddit, 3 experimental conditions and let us observe.

Christmas came early this year! Very happy to see our paper out in Science Advances. Led by @lfoswaldo.bsky.social, we ran a unique collective field-experiment on Reddit, to better understand who is participating in online debates and why. Paper: www.science.org/doi/10.1126/... And more below 👇

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...
