📣 Job alert! *Assistant Prof in Computational Social Science*. We're a friendly department, with sharp students, at a great institution, in a lovely city. We have real strengths in computational social science & are looking for a colleague to build this further. Share and reach out with quesions!

In just about a week, the season's first NetSci Colloquium will happen. And we're starting with a bang . . . with none other than Iain Couzin talking about Collective Behavior in Animal Groups. September 24, 10 AM ET. Register here to get a Zoom link: iu.zoom.us/webinar/regi...

The figures of old simulation papers are so vaporwave. (From: Gilbert & Conte (eds.), "Artificial Societies.")

💙New paper!💙 How is knowledge transmitted across generations in a foraging society? With @danielredhead.bsky.social we found: In BaYaka foragers, long-term skills pass in smaller, sparser networks, while short-term food info circulates broadly & reciprocally academic.oup.com/pnasnexus/ar...

My idea about "strong passports" is heavily influenced by the fact that the title page of Swedish passports (at least between 2005-2010) used to crack pretty quickly.

Network (visualization) of the day, by Duane M. Palyka (1968). From: Margit Rosen, et al. (eds.): A Little-Known Story About a Movement, a Magazine, and The Computer’s Arrival in Art: New Tendencies and Bit International, 1961-1973 (2011).

Super excited about our new paper on mobility that's out in Nature Human Behavior www.nature.com/articles/s41... I love this paper for many reasons, but one is that we find beautiful 1/x power-law that spans 6 orders of magnitude hidden within the "ugly" distribution raw mobility data.

Network of the day: A network of modernist writers. From "The Gender of Modernity" by Bonnie Lynn Scott (1990).

A survey of >99k people (110 regions) shows the Global North has denser belief networks, while the Global South has looser connections Inconsistency appears in areas (eg Mid East), where support for fossil fuels conflicts with support for renewables/climate policies www.nature.com/articles/s41...

There are several recent papers which could fall under the heading ‘Economic History of the Scientific Revolution’ but this network analysis tracing how scientific ideas diffused amongst scholars in the period 1084-1793 is a real milestone, an ‘epidemiological’ model of how ideas spread like disease

✨ The IAS Seminar Series returns for the Fall 2025 semester with a stellar lineup of speakers and thought-provoking talks. Open to all! #AcademicSky #Sociology #CSS

Network of the day. From: Epstein & Axtell, Growing Artificial Societies (1996). The book is, of course, a classic in the pre-network-science complexity science literature. But I, for one, forgot that it also contains networks.

Network of the day. From: Mirkin & Rodin's "Graphs and Genes" (1984).

Network of the day. From: Graph Games by Frédérique and Papy (1971).

New review article preprint: 🚨📄 www.arxiv.org/abs/2507.22799 It's about the interface between human mobility studies and epidemic modeling. (Hit me up if we missed your paper.)

Duncan Watts makes the very apt point that we should aim for CSS that both predicts and explains. Here is one of the few Q4 papers (more behavioral than social though): www.science.org/doi/10.1126/...

I'm happy to be a part of netreg.se . . A project to use register data to study the entire social network of Sweden. Check out our poster at IC2S2 today.

Posters, also provocative ones, are being set up now at #ic2s2

Day 1 Keynote by Dean Eckles: Effect sizes and decisions. How are your effect-size metrics actually decision-relevant, or just convenient to compute? #ic2s2

With record-breaking submissions and our most competitive, gender-balanced program on record, #IC2S2’25 has officially started! Please check the updated program and plan your day. #ic2s2

Network of the day. From a flyer for Turino's Club to Club festival.

Eno digging cybernetics is a nice parallel to Dalí wooing his hero Freud (AFAIR Freud was completely indifferent to Dalí's art but thought his mental state was somewhat intriguing). (The cybernetics founders were into classical music.)

(a bit late, but) this is a preprint/project I really have enjoyed! They might talk like us, but they surely don't learn like us. 📄🚨 arxiv.org/abs/2506.16163

It's been years since I discovered a paper that could enter my all-time top-10 list, but now it happened: Shager, Togg & Huberman's "A graph-dynamic model of the power law of practice and the problem-solving fan-effect" is one of the coolest papers I've ever read. 1/3 www.science.org/doi/10.1126/...

Yesterday's blog post has already been updated with a juicy new paragraph about the wisdom of the crowd 😁 and a poetic'er title petterhol.me/2025/06/26/e...

A new blog post where I set off on a search for moments of true collective intelligence in science, steps that would never have happened in a linear process of contributions from brain after brain petterhol.me/2025/06/26/s...

Presented our work with @c0rrad0.bsky.social, @bolozna.bsky.social, and Barbara Keller on user behavior change after cross-party interactions at #ICWSM today! Was a great experience and got a lot of interesting questions 🙌 Also: currently looking for postdoc opportunities - happy to chat!

Exploring Digital Services Act (DSA) and its implications for research. Exciting panel @icwsm.bsky.social with Oana Goga, Krishna Gummadi, Silvia Merisio, and Francesco Pierri. #icwsm

We are all very excited about this idea of matrix-weighted networks (MWNs) — always happy to discuss more!

🚨🎓 We’re looking for new PhD students! The area of specialization is open, but successful applicants should demonstrate a clear interest in themes that align with ongoing research at @iasliu.bsky.social 📅 Deadline: 31.08.2025 💼 Fully funded positions How to apply 👉 liu.se/en/work-at-l...

Straight to my CV 🤭 I was heavily featured in @sunelehmann.com 's ICSSI dinner talk. ( dx.doi.org/10.2139/ssrn... relates a bit to Sune's talk)

In this Review, Elisa C. Baek, Razieh Pourafshari & Joseph B. Bayer describe how four distinct uses of the term 'social connection' -- as subjective perceptions, social networks, synchrony & interpersonal behaviors -- have contributed to understanding this concept PDF: rdcu.be/erbWH

🧵1/8 In our new #OA article, we studied the drivers of ethnic school segregation. Research on segregation often points to parental preferences, but what if it's not just about what parents want, but also what options they actually have? 🔗 doi.org/10.1093/esr/jcaf027

Jacques Monod's "Chance and necessity" is an incredible book. Of course, a bit dated, but with plenty of truths modern science has inexplicably walked away from.

#NetSci2025 has a fun game to boost the poster session . . . as if that should be needed: petterhol.me/2022/12/20/t...

And we finish TENET by a great perspective by @pholme.bsky.social on the need for universality in temporal networks #netsci2025

If Petter's talk sparked your curiosity, his blog will feed it: petterhol.me/blog And here's a great interview on why and how he writes: youtu.be/Wtjo7eWE76E @pholme.bsky.social deserves a best blog award @netsciconf.bsky.social!
