Excited to visit NYU and Columbia this week for the workshop on AI and the Future of Online Information. Slides of my presentation here: www.dgarcia.eu/nyu-ai

An interdisciplinary team of researchers at the #UniKonstanz examines how AI agents reach a consensus. The results show that artificial intelligence operates similar to people in relationship to each other – but at a significantly larger scale. Details: t1p.de/7obk7 Giordano De Marzo @dgarcia.eu ​

gitfut.com/dgarcia-eu LOL you can make a football card of your github account. I'm a bit shocked I appear as a German using Javascript 😅

🔥 Happening now: The 2nd General Assembly Meeting of the WHAT-IF project is currently taking place in 📍 Bucharest, Romania. Over the coming days, partners from across the consortium will come together to share progress, discuss preliminary findings and explore new research ideas. Stay tuned!

🚨 New preprint Do LLMs have stable dispositions measurable using instruments designed for humans? Led by @jelenameyer.bsky.social, our new preprint shows that LLM responses are driven by response bias, rendering their psychological profiles method artifacts. @dgarcia.eu @arc-mpib.bsky.social

It was such a blast to give a talk at the Presidential Symposium of #APS2026bcn Slides are here: dgarcia.eu/CollectiveAI...

@uni-graz.at featured our brand-new article on collective moderation of online spaces published in @pnasnexus.org 🥳 Wanna read what citizen-based strategies can be a remedy against online hate? Click here: ow.ly/csZK50XGteK @janalasser.bsky.social @aroyehuns.bsky.social @dgarcia.eu

LLMs excel at mimicking individual text, but what about collective conversations? 🤔 In our recent paper 📄, we conducted a Turing Test to see if GPT4 and Llama 3-generated social media conversations can fool humans into believing they're authentic! arxiv.org/pdf/2511.08592

Misinformation research has a causality problem: lab experiments are limited; observational studies confounded. We used causal inference on 9.9M tweets, quantifying effects in the wild while blocking backdoor paths. Does misinfo get higher engagement? Are following discussions more emotional? 🧵

Do LLMs represent the people they're supposed simulate or provide personalized assistance to? We review the current literature in our #ACL2025 Findings paper and investigating what researchers conclude about the demographic representativeness of LLMs: osf.io/preprints/so... 1/

Excited to present our paper with @maxpe.bsky.social, @dgarcia.eu, and @mstrohm.bsky.social next week at #ICWSM! ✨ We extend social simulation with LLMs to a longitudinal setting by fine-tuning Temporal Adapters—here's how: 🧵

New preprint with @jbakcoleman.bsky.social @lewan.bsky.social @randomwalker.bsky.social @orbenamy.bsky.social @lfoswaldo.bsky.social where we argue for a complex-system perspective to understand the causal effects of social media on society and for a triangulation of methods arxiv.org/abs/2505.09254

A few months ago I was like "why is there so much gay porn in my anti-AI app" and now there is none of it in my discover feed. It's just a matter of time for the algorithm to sort it out.

Are you interested in inequalities, mobility and cities? Come to work with us as a postdoc at @ceu-dnds.bsky.social in Vienna in the Computational Human Dynamics Lab of @martonkarsai.bsky.social. Check the post here: careers.ceu.edu/job/Vienna-P... @ic2s2.bsky.social @netscisociety.bsky.social

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they? One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers. 1/n

"I can do things with LLMs" seems to be the next "I can get Twitter data" in Computational Social Science. Not that I think it's bad, it's just funny to see how things change.

We are looking for a German-speaking lab manager for the Social Data Science lab in Konstanz. More info here: stellen.uni-konstanz.de/jobposting/4...

I'm really happy to welcome David Garcia @dgarcia.eu at the DM3L for a talk on "Polarization and consensus: between online discussions and generative agents" Join us if you are in Zurich next Thursday! dm3l.uzh.ch/news?nId=69

Our open review portal is down, but our team is working to resolve the issue as quickly as possible. In light of this, the submission deadline has been extended to Feb 26, 23:59 AoE. We appreciate your patience and apologize for any inconvenience caused.

How politicians communicate shapes online discourse in ways we might overlook. Our new paper shows that their choice between a fact-based (evidence-driven) and a belief-based (sincerity-driven) honesty creates a "contagion" effect, influencing how users engage and respond. ⬇️(1/8)

Hello world! Meet our consortium—15 organizations, 10 countries—joining forces to rethink the digital political information space. 🚀 Last week, we kicked off our project WHAT-IF, setting the stage to build a digital twin that will help us test the impact of policy interventions. More in the 🧵!

It's supercool that Deepseek v3 is open, but it's pretty censored at least through the Android app. It refused to answer about Tiananmen and when asked about the capital of Taiwan, it deleted the output mid-generation.

If you are interested in studying good old human activity on pre-Musk Twitter, we are now sharing the complete 375M dataset of our 24h Twitter data collection with researchers. Get in touch! ojs.aaai.org/index.php/IC... Please forward to interested scholars.

😡Emotions ≠ 🤓Reasoning?! Nope! 😎 @apeksha.bsky.social's & @julaluehring.bsky.social's first PhD paper on recognizing COVID-19 misinformation & links with emotions got accepted! If you haven't already seen the preprint, have a look at the paper or this 🧵! doi.org/10.1186/s412...

I'm glad to announce that I just started as co-Editor-in-chief of EPJ Data Science with @yelenamejova.bsky.social Looking forward to building the community around one of my favorite journals! www.epj.org/113-epj-ds/2...

I have an open 3-year PostDoc position in my research group, centered on the extraction and analysis of relations of societal actors (e.g. politicians, CEOs, ...) from unstructured text data. Feel free to reach out if you want to know more! Deadline is Jan 1st. jobs.uni-graz.at/en/jobs/a122...

Happy new year!

Which celebrities are the most popular and unpopular on social media? We are working on a new Holiday Paper Series article on that! We are changing to a Summer schedule for the HPS. On the meantime, here is a teaser for Elon Musk, Mark Zuckerberg, and Britney Spears: dgarcia.eu/CSS_Holiday_...

Very interesting paper that is making rounds on Bluesky but please notice this issue is for *proprietary* LLMs like the OpenAI ones. Running Llama locally was remarkably stable. In general, using any kind of proprietary software, especially through an API, is bad for reproducibility.

Join us tomorrow (Friday, December 13th) for the fourth talk in the I2SC Lecture Series by @dgarcia.eu from 12:00-13:00 in building E 1.7, Room 3.23.

Job announcement: Junior Professorship in Computational Social Science at the University of Konstanz. Join us at the Center for Data and Methods! Feel free to reach out if you have questions. stellen.uni-konstanz.de/jobposting/2...

Looking forward to giving a talk about gender inequality in digital traces and AI today at 15:30 at ETH Zurich: www.swish.ethz.ch/events/ Slides are available here: dgarcia.eu/eth-gender-2...

Curating and sharing high-quality datasets is the foundation of good empirical science. @icwsm.bsky.social promotes dataset creation through a dedicated conference track published in the conference's regular proceedings. Submit your dataset paper by Jan 15th! www.icwsm.org/2025/submit/...

Hi, so I've spent the past almost-decade studying research uses of public social media data, like e.g. ML researchers using content from Twitter, Reddit, and Mastodon. Anyway, buckle up this is about to be a VERY long thread with lots of thoughts and links to papers. 🧵
