NERDS

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 🤖

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!

My collaborator @bokanyie just gave a fantastic talk at #ic2s2 about our "urban highways" paper https://www.pnas.org/doi/10.1073/pnas.2408937122

If you have arrived in Norrköping for #ic2s2 and wonder if you should jump into the Glan then yes you absolutely should. Weather & water are fantastic!

Kunstige intelligenser er for første gang blevet undersøgt, når de agerer i flok, med samme metoder, som sociologer bruger. Der er påfaldende ligheder i adfærden – med skræmmende konsekvenser.

Apparently, the number of climate-related tweets in European regions correlates with actual sustainable actions people take

Presented this at the DWMV workshop @ #ICWSM, thanks to @isi.it for hosting and letting me share this work done with @lajello.bsky.social at the @nerdsitu.bsky.social group :)
