@brunelcce.bsky.social was well-represented at #ehbea2026. @replicatedtypo.bsky.social presented on ‘The cultural evolution of problem-solving’ and @abbeyepage.bsky.social on ‘When the village predicts the next baby: post-natal social support and fertility intentions in the UK’ (sadly no pic)

The common assumption that evolution is a process to improve species and the solipsistic belief that humans are the best thing ever. Which shouldn’t coexist with academic training but does. And/or the idea that cultural evolution replaced biological evolution which I think I was taught.

Did some reading today in astronomy (active galaxies and compact objects), and started a new burst of serious work on the Cultural Evolution Game.
It's been a rough week. Possibly due to the pollen - it's hard to feel enthusiastic about projects when you're not feeling well. Still slogging forward.

Yep, Plato, Aristotle, Aquinas as I mentioned.
Or are you saying all thought just stopped at Plato and there's no cultural evolution?

New preprint with Rafael Leite, Sandro Reia and Paulo Campos
Cumulative Cultural Evolution in Structured Populations
www.biorxiv.org/content/1….
In which we take an old model of cumulative cultural evolution of mine and see what happens if you add social networks

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.

You have the entirety of the internet to investigate my statement (also that modern science emerged from Christian tradition) but you wont because your dogma prohibits it.
Quite interesting really. Its a psychological threat to you to acknowledge historical cultural evolution.

In the same bucket as EvoPsych. There very likely is a there there but so well serves existing power structures it's too deeply contaminated to take seriously.

Science wholesale just doesn't offer the kinds of resources for social analysis people obsessed with evopsych (claim) they want it to provide. It's not a biology-specific thing, biology is just the level at which they can pin the claims they really want to make.

if there were some staggering insight that would cause a Copernican revolution in social analysis and policy coming from the kitbag of evopsych and population genetics popular in secular right/center-right circles, we would have seen it already.

Also did some work with the Cultural Evolution Game: a quick test run to derive inspiration for the fantasy setting I'm working on. Tweaked a couple details of the CEG along the way, so that's progress.
More of that tomorrow, I think, and maybe some new rules material as I go. (2/2)

Second day of @ehbea2026.bsky.social done!
Full day, full of nice discussions, a wonderful talk from Anna Rotkirch, a fruitful panel discussion about AI and science, and poster session!
Looking forward for tomorrow! 👀

Cultural evolution over 80 years is a hard frame because the generation length is so short relative to the institutions. Henrich, Mesoudi, and Richerson all run into the same measurement problem.

AI Go agents converging on joseki humans developed over centuries is the cleanest case of cultural evolution I know of. The search space has attractors that both biological and artificial learners find.

Cultural evolution misunderstanding usually comes from mapping Darwin onto ideas too cleanly. Variation, selection, inheritance still apply, but the substrate is different. Ideas persist through fidelity of transmission, not replication.

It's been great seeing her cultural evolution from an opera singer with little knowledge of popular music to interviewing cool artists like Ren and absolutely loving music thru the decades.
Have you ever seen the UK show Faking It?

Nice :-)
I don't think Active Inference / the FEP is sufficient to describe or explain autopoiesis. It arguably grounds an enactive theory of mental content / concepts though.
Here are some stuff I've written on cultural evolution:

Aside from messing around a bit with the upcoming "Pioneer" game, I spent most of today doing some reading in my mathematics and astronomy courses.
Also reviewing the current state of the Cultural Evolution Game, and trying to figure out how to push that to its next milestone. It's a challenge.
