We must come to terms with the fact that it was a huge mistake to leave the online world largely unchecked, and that we urgently need to deal with a fragmented, radicalized and instrumentalized reality in many countries simultaneously and take action instead of remaining in shock or relativization.

🚗 💥 Excited to share that our latest article is now published in Sustainable Cities and Society! 🔗 lnkd.in/gE8QyWAH 💫 First study to use mobile phone activity data to estimate CO2 emissions validated with emissions sensor measurements

Accepted to #CCS2025 but need help covering costs? The #OpenArmsGrant supports attendees from low- and middle-income countries with travel, fees, and more. Budget should never be a barrier to participating in science! Apply by June 15. ccs25.cssociety.org/open-arms-gr... #ComplexSystems

🤦

Extremely excited about this *new preprint*, where we use a collective field experiment with our own subreddits, which allowed us to uncover diverging factors for online participation between the very active and the passive. More details by the (as usual) *amazing* lead @lfoswaldo.bsky.social below👇

This is insane

How do major real-world events shape online conversations? With Anna Mancini, @giuliocimini.bsky.social @ric-dicle.bsky.social we found that while activity surges, users repeat the same ideas at an accelerating pace, limiting meaningful discussions.

oh wow…this is a whole new level…conspiracy level intesifies 😅

Hello Bluesky! We at CCS 2024 are cooking something up for you! Be sure to follow us and don't miss the big announcement! 👀👀

What happens when forma mentis networks meet Large Language Models? In our recent paper we find even ChatGPT's LLMs replicate negative attitudes to maths and STEM found in high-schoolers: doi.org/10.3390/bdcc... LLMs can reflect human affective biases and we need tools to investigate this further!

Our latest paper reports on fake accounts that use AI-generated profile pictures, like those below. We estimate ~10k daily active users like these on Twitter. w/ @yang3kc.bsky.social & Danish Singh Preprint: doi.org/10.48550/arX...
