It was great to have Paul Smaldino @psmaldino.bsky.social with us today, discussing evolutionary approaches to human culture and society. As a bonus, we learned why we are wearing pants.

The calm before the storm 🤘

This Wednesday, 24 September 2025 at 14:30, our Professor Luca Aiello @lajello.bsky.social will give his inaugural lecture in Auditorium 0 at the IT University in Copenhagen! en.itu.dk/About-ITU/Pr...

Prof. Paul Smaldino @psmaldino.bsky.social will join us in Copenhagen on Wed, Sep 24, 12:30-13:15 to present at an exciting data science seminar! Topic: Why Use An Evolutionary Perspective To Study Culture? To attend, see: nerds.itu.dk/event/data-s...

A great collaboration! In this study led by Theodora, we found that positive emotions are more present at distinct stages of activism (calls-to-action, expression of intention, report of participation), showing how emotion and mobilization interact in spoken discourse 🗣️

* Decoupling geographical constraints from human mobility * 🌍🚶 How much of our movement is about human choice and how much is constrained by geography and the spatial layout of locations? Our paper (out in Nature Human Behavior) gives you a practical way to tell: www.nature.com/articles/s41...

Yesterday I presented a recently-published paper on dynamic triadic closure processes at the Feedback and Cooperative Effects in Net Soc Dynamics Satellite at CSS! Thanks to the organisers for inviting me, I had a lot of fun! Here’s the paper tinyurl.com/3s5f3ekd 👀

Last week I was in Norrköping for the @ic2s2.bsky.social conference! Had a great time listening to research from around the globe 🌍 Also presented some early results from a survey experiment about the influence of governmental AI on the trustworthiness of public institutions that use it 🤖

NERDS at IC2S2 in Norrköping nerds.itu.dk/2025/08/01/n...

Back from #ic2s2 which was again a fantastic conference experience - congrats to the organizers! Some professors got a poster this time, which was actually super fun to design and present - haven't done it since my 1st year of PhD 16 years ago 👴

My first time at @ic2s2.bsky.social is one I won't forget 💫 I gave three parallel talks (🤯) and each of them led to insightful conversations with brilliant researchers from around the world. This conference exceeded my expectations. The computational social science community is fantastic 🫶

Just back from #IC2S2 2025 in Norrköping! I presented a poster + talk on VLLM-based clustering of social media images around climate change polarization. Huge thanks to the organizers and the whole community for the great discussions and inspiration! #Polarvis #NERDS #ITU

The work “Extracting Participation in Collective Action from Social Media”, in collaboration with @lajello.bsky.social, at @ic2s2.bsky.social today! Check out the paper ojs.aaai.org/index.php/IC... and models huggingface.co/ariannap22 Feat. poster and research buddy @alessianetwork.bsky.social ♥️

Presented our work, “Cultural and Cognitive Insights from 2.6 Billion Drawings,” at @ic2s2.bsky.social this morning. Big thanks to Mauro Martino, Nima Dehmamy, @douglasguilbeault.bsky.social, @lajello.bsky.social, and @baronca.bsky.social for the collaboration ✨ Stay tuned for more results!

AI-assisted social media posting increases the volume of content people produce. However, that content is perceived as lower quality than purely human-generated posts. A dangerous spiral that may flood social media with low-quality content. Results from a controlled study: arxiv.org/abs/2506.14295
