Joint #HBES2026 / #CES2026 plenary 🎤 Hugo Mercier on "The evolution of reason and the cultural evolution of reasons." With Dan Sperber, he’s argued reason isn’t a fix-everything mechanism — it’s a social one. A thread 🧵

Great times with the EC at #HBES2026 in Morocco! 🇲🇦

Plenary 1 at #HBES2026 🎤 Brooke Scelza on “More Than Our Differences: Moving beyond dichotomies in the study of human mating.” Drawing on 15 years with the Himba of NW Namibia, she pushed us to broaden how we frame sexual selection. A thread 🧵

What's really clear from today's #CES2026 - #HBES2026 panel is how much we've come to work together, across the evolutionary social & behavioral sciences. Monique Borgerhoff Mulder sums it up: "The gaps between evolutionary psychology, human behavior ecology, & cultural evolution have narrowed"

A strong start to the conference, bringing together scholars and researchers from diverse disciplines to exchange ideas and advance the field.

Thanks @unlincoln.bsky.social & @unlcas.bsky.social for promoting our work! sgis.unl.edu/news/lincoln...

Fitting to see this out w/ @hbes2026.bsky.social around the corner. @rayhames.bsky.social, last year's #HBES Lifetime Achievement winner, gave us a brief history of the society. Martin Daly will build on it with a panel, The History & Prehistory of HBES See all you *The Podcast* talking heads soon

Join us in Barcelona for a postdoc! We are looking for candidates with a strong NLP/ML/AI background and an interest in linguistic diversity and human and machine cognition: dub.sh/blasi_nlp_po...

Thanks (in advance!) to the organizers of @ces2026.bsky.social and @hbes2026.bsky.social for hosting these two conferences in Morocco, thus giving me (and many others) the excuse to visit this magical country and continent (for the first time!) Shukran bezzaf. See you soon in Rabat.

@lfanpsych.bsky.social set up this participant-driven ride share sheet for @hbes2026.bsky.social attendees arriving to the Rabat airport for #HBES2026 This is not managed by the local organizers or @humbehevosoc.bsky.social, but we're happy to spread the word.

Conference update emails for #HBES2026 and #CESRabat will be sent soon. In the meantime, updated programs are live on both conference websites: airess.fgses-um6p.ma/hbes2026 airess.fgses-um6p.ma/ces2026 Check them out! @ces2026.bsky.social @hbes2026.bsky.social

I'll be presenting this work at the Cultural Evolution Society (CES) 2026 Conference in Rabat, Morocco (airess.fgses-um6p.ma/ces2026) on May 13. If you attend the conference and are interested in this, let's talk!

How do filmmakers portray POWER? Pretty closely to how evolutionary social scientists would tell them to. Here's a great video on power in film: www.youtube.com/watch?v=CaIF... ... ...which echoed this paper beautifully: Durkee et al. PNAS (2020) www.pnas.org/doi/pdf/10.1... Science + art 🎨

There is a fully-funded PhD position at the Max Planck Institute for Evolutionary Anthropology to pursue dissertation research among the Mayangna of Nicaragua, expanding a longitudinal study of subsistence strategies and behavioral ecology. Please share the posting! www.eva.mpg.de/career/posit...

Q: How’s the end of the semester going? A: 🎾 @weratedogs.com

If you want to collaborate on Qmd, Rmd, or md files for reproducible manuscripts, try out the alpha version of Quarto Review! It does track changes, comments, syncs with git, shows differences between versions! github.com/Lakens/Quart... Tell me the bugs and feature requests!

Statistical Rethinking 2026 is done: 20 new lectures emphasizing logical and critical statistical workflow, from basics of probability theory to causal inference to reliable computation to sensitivity. It's all free, made just for you. Lecture list and links: github.com/rmcelreath/s...

Priceless interview for all anthropologists and fieldworkers. Thank you, @ilarimakela.bsky.social & RB Lee!! Lee’s discussions on establishing new field sites closely parallel my experiences in the Omo in Ethiopia with the @omovalleyresearchproject.org

Looking forward to Jamie Tehrani's guest lecture in my cultural analytics course, open to everybody. If you are in Trento and want to know more about cultural evolution, that is a great opportunity! eventi.unitn.it/en/origins-s...

The Selfish Gene (TSG) was published 50 yrs ago. I was recently asked about Dawkins' concep of the selfish gene in light of my review many years ago of Burt & Trivers' book on selfish genetic elements: www.science.org/doi/10.1126/... Here is my response (lightly edited): 🧪 #BioAnth 1/14

The social excursions for @hbes2026.bsky.social will be held on the 17th of May, after the conference. (There was a mistake in the date in the email sent out to HBES members.) Talk to your friends to coordinate on which one you may want to join. @humbehevosoc.bsky.social #HBES2026

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

A very important study. Many figured that chimp warfare was adaptive. Now we have proof. Lethal displacement of a neighbor doubled fertility and even had a greater impact on survivorship. However, as usual we need more details as other questions emerge. www.pnas.org/doi/full/10....

A raw portrait of rural poverty and inequality in late French-colonial Vietnam during World War II, when food was scarce and family support often wasn’t enough. Worth reading if you like short stories.

1. My new preprint has its own bluesky account. Why? The problems facing social media & scientific publishing are similar: both are dominated by powerful oligopolies. The @atproto.com tech underlying bluesky that aims to solve the social media prob might also help solve the scientific pub prob 🧪 🧵
