Back from holiday with a bang 💫 Am pleased my article Artificial Utopia is now published in the journal Futures. lnkd.in/e_fnEbg3 This article conceptualises thinking about Utopian and radically socially innovative societies with the help of computational simulations.

I believe that if you are interested in modelling social change, also in relation to climate change, postgrowth economics etc. this winter school could be quite useful to you. schumpeter-centre.uni-graz.at/de/veranstal...

Why the German chancellor is wrong - the focus on increasing working time is misguided - and what to do instead open.substack.com/pub/theworld...

Here is a blog on the current debate around increasing work time in Germany. Instead, we must think out of the box and experiment with drastic economic and social innovation. theworldinmodels.substack.com/p/why-the-ge...

Sorry to link to X, but I am so glad another (senior) person is speaking out about this, it is a different field than mine but I had the same problem with a paper that got rejected and even an ERC grant application. x.com/Michael_J_Bl...

👉AI for good? AI for agent-based models? What kind of forms could this take. Please note the deadline to our SSC special track this Friday! We are looking forward to your research. 👉Also Please spread if you can!!😀

👉🙌 😀I am happy to share my new article (preprint) Artificial Utopia: Simulation and Intelligent Agents for a Democratised Future arxiv.org/abs/2503.07364

But evidence shows different already. Here is a study showing that LLM generated ideas are judged as more novel than researcher generated ideas in NLP. arxiv.org/abs/2409.04109

Crazy that in this whole tumult around Zelensky and Trump, the Americans, Trump and his friends, also just swept under the rug that Russia already allied with North Korea and North Korea literally has troops fighting alongside Russia against Ukrainians. But sure *Zelensky* gambles with WW3.

One scenario the EU must be prepared for now is the U.S. lifting sanctions on Russia. Key principles for the EU: - make sure to stay united - not return to dangerous dependencies - not deliberately support the Russian war economy Not changing anything might not be the right answer

I am reading and learning about models of opinion and cultural change and diffusion. Particularly with relevance to agent-based models or network models. The main classes I have identified so far are as follows. Anything I am missing?

Has the Dawn of Everything by Graeber and Wengrow be misintepreted by a lot of people? They actually argue themselves that hierarchical and egalitarian societies are around since complex social life emerged, not that all hunterer gatheres were egalitarian. research-portal.uu.nl/ws/portalfil...

Exciting News 📣🫵 Wolfram Barfuss and I are organising a special track at the Social Simulation Conference 2025 in Delft. On "Artificially Intelligent Agents in Social Agent-based Models" The call is out now. ssc2025.tbm.tudelft.nl/important-da... Looking forward to exciting contributions.✍️

👉Happy to have contributed a tiny bit to the writing of this new article: Understanding Pedestrian Dynamics using Machine Learning with Real-Time Urban Sensors journals.sagepub.com/doi/10.1177/...

Really good blog on the nature of authorships and citation pressure. I think academia should make itself honest about this and try not to constantly reproduce that system... blogs.lse.ac.uk/impactofsoci...

Periodic reminder that the smallest nations of Earth, including many island states, emit only a fraction of industrialized nations. Here is a comparison between the 50 least emitting nations and what super low fruit hanging policies in Germany could have saved (under the now defunct government).

Citizen assemblies (CA) are often thought to decrease polarization on sensitive issues. However there is a surprising amount of literature showing other effects. E.g. this experimental study found students became *more* ideological through a modelled CA. www.tandfonline.com/doi/full/10....

Really sad to see 😔

This piece by Marco Pangallo is one of my favorite recent articles. It discusses the concept of equilibrium in economics recognizing that it actually has a lot do with systemic complexity thinking but still adding a justified critique. papers.ssrn.com/sol3/papers....

Definitely one of the biggest mistakes. Next to autocratic capitalists and capitalist autocrats controlling basically the entire economy and sending us to climate and inequality hell.

Thrilled to share that I have officially graduated as a Doctor in Evolutionary Biology and Social Sciences from The University of Sheffield @sheffielduni.bsky.social. Thanks to my supervisors Ellie and Anna @annakspeaking.bsky.social, my husband @yloswald.bsky.social, my parents, brother & friends.

Hard to process the devastation I’ve witnessed in the last two days. Still in a state of shock for those who have lost so much in such a short period of time. #NoWords 💔

I am generally for climate protests for obvious reasons. What the UK is doing horrible here but can someone explain these results to me? Why is that labeled as clear evidence for protests working. All I see is null results. ->

Great video on political biases in scientific information assessment by Veritasium www.youtube.com/watch?v=zB_O... Largely based on this study papers.ssrn.com/sol3/papers....

I think one great and underappreciated point about lists is that now if I want to educate myself about a certain topic and follow a few experts, I know where to look. Even without immediately following the entire list. Super useful.

If business cycles are (at least partly) caused by forces endogenous to the economy, rather than by exogenous shocks, it is much easier to explain why economic activity tends to co-move across countries. New paper in JEBO: authors.elsevier.com/a/1kB5Vc24b7... 🧵👇

Since I never shared in the new, more amicable, space here is my current working paper on "Global convergence of incomes in a climate‐constrained world" which aims to scope the general scenario space of global income convergence and emission implications.

Things I can say about my bsky account but not about my X account... 1) Zero bot followers so far.

Interesting. It is because of the communities introduced I'd say. And in the long-run I expect the usual distribution to emerge. But let us see.

Three little books with really big ideas…

Very interesting article. I ask myself this question everyday since I live here. Indeed public transport could not be more punctual and frequent, except, and of course 🙃, during rush hour in the afternoon. www.swissinfo.ch/eng/swiss-po....

It's great to see the massive wave of people coming to 🦋. Here's my first stab at a Computational Social Science starter pack: go.bsky.app/2m6iQ68 Go check out similar lists to bootstrap your network: bsky.app/starter-pack... bsky.app/starter-pack... Wonder if these lists could be merged somehow..

The country of Tuvalu is building a digital twin of itself to ensure the surival of its nation. It is forced to so because of rising sea levels and climate change. academic.oup.com/ia/article/1...

Our paper on An Agent-Based Model of the 2020 International Policy Diffusion in Response to the COVID-19 Pandemic is cited only 2x, but it is cited in a metaphysical discussion of what computational simulations actually are and represent😄😍. cool! metaphysicsjournal.com/articles/10....

Another #COP29, more empty promises? 😵‍💫 No country but China, India and the USA matter? 🤔 Now that Trump will be US-President again, all is lost anyway? 😱 What people and policy makers need to understand is that every country's policy decisions matter. 💯 🌿 👇

Overall, Trump won with 51% to 49% of all votes. Hardly a landslide. America pretty much 50/50 polarised as ever. Source @TheEconomist
