Our study of 400 million tweets shows that the “war on science” is far more complex than a simple clash between truth and falsehood.

Q4. If AI is the answer to online disinfo, what role is left for human judgement in deciding what counts as trustworthy information?

#AICODEPROJECT

Q5. Will AI tools empower citizens to spot disinfo themselves – or just hand more power to platforms and gatekeepers?

#AICODEPROJECT

Q3. Can AI really foster trust online, or do we first need to rebuild trust in the people/institutions deploying it?

#AICODEPROJECT

Q2. Is the biggest challenge building better AI, or convincing the public that AI-backed systems can be fair and transparent?

Q1. Can any tech stay ahead of disinformation tactics that evolve just as fast?

Predicting human cooperation: sensitizing drift-diffusion model to interaction and external stimuli | Journal of The Royal Society Interface Human cooperation arises naturally and is essential for the development of successful societies. This study aims to identify which aspects of the interaction influence societal cooperation and defection. Specifically, we investigate human cooperation ...

Mapping the interaction between science and misinformation in COVID-19 tweets. Publication from @luzuzek.bsky.social, Juan Pablo Bascur, @annabertani.bsky.social, @ricgallotti.bsky.social. This project is supported by European Media and Information Fund. Abstract: During the COVID-19 pandemic, scientific understanding related to the topic evolved rapidly. Along with scientific information being discussed widely, a large circulation of false information, labelled an infodemic by the WHO, emerged. Here, we study the interaction between misinformation and science on Twitter (now X) during the COVID-19 pandemic. We built a comprehensive database of 407M COVID-19 related tweets and classified the reliability of URLs in the tweets based on Media Bias/Fact Check. In addition, we use Altmetric data to see whether a tweet refers to a scientific publication. We find that many users find that many users share both scientific and unreliable content; out of the 1.2M users who share science, also share unreliable content. Publications that are more frequently shared by users who also share unreliable content are more likely to be preprints, slightly more often retracted, have fewer citations, and are published in lower-impact journals on average. Our findings suggest that misinformation is not related to a ``deficit'' of science. In addition, our findings raise some critical questions about certain open science practices and their potential for misuse. Given the fundamental opposition between science and misinformation, our findings highlight the necessity for proactive scientific engagement on social media platforms to counter false narratives during global crises.

New preprint! 🚨

We study the interaction between misinformation and science on Twitter during COVID-19 based on ~407M tweets. Both science and misinformation featured prominently during the pandemic, but the interaction between the two has not been studied on this scale before.

I'm also very happy that this conference brought me back just a few hundred meters from where I used to live in the 5th arrondissement. (And no, I wasn't rich - I was sharing a triple room!)

I finally have the pleasure of attending Sunbelt in person for the first time, together with four members of my unit @chub-fbk.bsky.social
This year among the organisers we also have many familiar faces such as @camcom.bsky.social , @chavalarias.org , Floriana Gargiulo and Emmanuel Lazega.

Universal roughness and the dynamics of urban expansion We present a new approach to quantify urban sprawl using tools from surface growth physics. Analyzing built-up area expansion in 19 cities (1985-2015), we uncover anisotropic growth with branch-like e...

How do cities expand?
Using surface growth physics, we found a unique exponent governing their local geometry. Instead, their dynamics range from smooth diffusion to abrupt coalescence, with demographic pressure driving where each city lands on that spectrum.
