Our Summer school "Narratives of Disruption and Continuity in Science, Technology and Society" begins at the @uni-wuppertal.bsky.social 🎉 First keynote speaker is @frapierri.bsky.social from Milan, about the regulation of online platforms in the age of misinformation!

Great work, congrats!

Did you look at whether underserved languages might be disproportionately relying on machine-assisted moderation (not sure if this information is available though)?

Social media platforms operate globally, but do they allocate human moderation equitably across languages?

Our new WP shows the answer is no:

-Millions of users post in languages with zero moderators
-Where mods exist, mod count relative to content volume varies widely across langs

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

This is a poor argument against LLM simulations. It suggests that LLM-based behavioral models should capture nuances that no model ever has (do agent-based models go to the toilet?). Ofc, ABM is meant to be interpretable, but social science also needs predictive power (where LLM simulations excel)

TL;DR
We use open LLMs to study online conspiracy theories on TikTok leveraging videos' transcripts, and estimate a lower bound prevalence (0.1%) of such content on the platform looking at over 1 M random sample of US videos collected through the Research API.

Our paper "Conspiracy theories and where to find them on TikTok" has been accepted at the Main conference of @aclmeeting.bsky.social 2025!

Great work led by @fracorso.bsky.social supervised by @gdfm.bsky.social and yours truly.

Do Large Language Models Solve the Problems of Agent-Based Modeling? A Critical Review of Generative Social Simulations Recent advancements in AI have reinvigorated Agent-Based Models (ABMs), as the integration of Large Language Models (LLMs) has led to the emergence of ``generative ABMs'' as a novel approach to simula...

Large Language Model-based social simulation has emerged as an exciting new research method.

But do LLMs actually resolve the problems that have historically limited use of Agent-Based Models? What do they bring?

We review the literature to find out!

New paper out in npj Complexity today.

We construct large data-informed US-based contact networks (~20M nodes) and explore how misinformed populations can affect the spread of disease.
