A multilevel network approach to revealing patterns of online political selective exposure

1. Kevin Gross and I just posted a new science-of-science preprint.

This one explores the looming peer review crisis. As many of you know, it's becoming significantly more difficult for journal editors to find scholars willing to serve as peer reviewers for submitted manuscripts.

Will anyone review this paper? Screening, sorting, and the feedback cycles that imperil peer review

Scholarly publishing relies on peer review to identify the best science. Yet finding willing and qualified reviewers to evaluate manuscripts has become an increasingly challenging task, possibly even ...

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.

🧵 (1/10)

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.

The Detox Workshop at @icwsm.bsky.social has wrapped up. Thanks to our keynote @maxfalken.bsky.social , all our speakers, my co-organisers, and everyone who joined the event! 🫖
We don’t have all the solutions yet, but it’s clear that tackling platform harms requires new methods and data sources!

10 years ago, I went to my first #NetSci. I had just finished my PhD, had nothing to present, knew nobody, but I knew I was finally where I wanted to be. Fascinating science and people. I feel very lucky to have helped organize @netsciconf.bsky.social this year and to have brought my great students!

Now that #NetSci25 is over and the adrenaline has settled, all I can say is: thank you! It's always a blast - and winning an unexpected prize makes it even more special.

I hope e-values found a place in (some of) your hearts. Stay tuned, the paper is coming soon!
