📢 New preprint: Urban highways are barriers to social ties: arxiv.org/abs/2404.11596
We overlay the highway network with a massive, geolocated online social network, and measure how social ties are impacted by highway segments in 50 US cities.

New paper out: "More is different" & the LLMs.
LLMs are usually studied in isolation. But what happens when they start interacting? We explored this by looking at their collective behaviour.
With Ariel Flint Ashery and @lajello

Excited to share our new article published in npj Complexity with @lajello , @Gius_C , and @lau_retti , where we shed light on the dynamics behind the first large-scale financial collective action driven by social media users: the #GameStop short squeeze.

New paper accepted! @LentiJacopo will be in #TheWebConf25 in Sydney 🇦🇺🦘 to present "Causal modeling of climate activism on Reddit", carried out during the visiting at ITU of Copenhagen, in collaboration with @lajello , @c0rrad0m0nti and @gdfm7 . Paper: arxiv.org/abs/2410.10562
New tool to estimate the level of participation in collective action expressed in natural language.
Applied to social media, it can produce large-scale and granular estimates of behavior change wrt collective action.
Check it out: github.com/ariannap13/extrac…
@Carlsbergfondet @ITUkbh
Excited to share the tool @lajello & I built to predict social media participation in collective action! It moves beyond keywords, tracking activism stages across topics. See it in action with climate activism on Reddit 🌱

Please consider submitting to this initiative.
We plan to fund at least a 4-5 students from the Global South to travel to Copenhagen and attend ICWSM
If you know anyone who might be interested please forward.
We are excited to bring back ICWSM-Global Initiative also this year, 2 pg. applications due 15/01 for:
- Travel expenses coverage to the conference in 2025
- Mentorship support from a senior academic in the field

📢 Fresh off the press: Human-AI Coevolution 🚀
PDF: barabasi.com/science/publica…
Humans & AI shape each other in feedback loops with big societal impacts. Bridging AI, complexity science & society, with real-world examples.
A call for a new interdisciplinary field! #AI #Complexity

Excited to see this finally out. Here a 🧵 on the topic.
Very happy to see that our paper on "Higher order connectomics of human brain function" is now out in @NatureComms . Lots of fun! Last one by the great @andreasantor0 , with @lordgrilo @fede7j @maximelca nature.com/articles/s41467-0…

🎉 Paper alert!
We explored how LLMs can generate engaging content in social networks, adapting to user opinions and network dynamics. Using RLSF, our approach aligns content to topics to maximize engagement.

New paper: Do social media algorithms shape affective polarization?
We ran a field experiment on X/Twitter (N=1,256) using LLMs to rerank content in real-time, adjusting exposure to polarizing posts. Result: Algorithmic ranking impacts feelings toward the political outgroup!🧵⬇️

Our Prisoner's Dilemma work got accepted to @icwsm!
Looking forward to next year's edition in Copenhagen.
@frapi9
Testing LLMs in Game Theory experiments reveals their moral biases as social agents -- useful to inform alignment. Llama2 playing Prisoner's Dilemma is more forgiving and non-retaliatory than humans, but only when the opponent defects rarely. New preprint: arxiv.org/abs/2406.13605

The Twitter exodus has started, but maybe it should have started long ago?
Our new study in @NatureComms shows that political abuse on X is a global, widespread, and cross-partisan phenomenon
