📣 Upcoming seminar: 'Social and epistemic inequalities in science: insights from a multi-method study of forest research', with Nelius Boshoff (Stellenbosch University) and Susanne Koch @tum.de. 📅 Friday, 5.12.2025 | 3:00-4:15 PM (CET) 📌 Online & at CWTS www.universiteitleiden.nl/en/events/20...

It's easy for some of you to just never use LLMs and just criticize people who do. I would like to be in that situation. But here I am, with my moderator volunteers, assessing hundreds of papers submitted to @socarxiv.bsky.social, trying to decide how to fairly judge whether to accept them. /1

2. We are developing a policy for AI-related work. We need a formal policy on AI-generated and LLM-assisted content. We have formed a committee of volunteers from our social science and library science networks to gather existing policies and decide what to do. /5

An adversarial collaboration on "cancel culture" reveals that many university students support restrictions on academic debate and research on campus, including the cancellation of talks, the revocation of teaching positions, and the removal of books. www.pnas.org/doi/10.1073/...

Does blinding--i.e., concealing applicants' identities--reduce gender gaps in academic conference paper acceptances? Nope! Does blinding do anything? It does! Blinding reduces gaps in acceptances by institution rank. haruka-uchida.github.io/websitefiles...

Our preprint is out! www.biorxiv.org/content/10.1... Peter Skovorodnikov and I are excited to present FERAL: a new video-understanding toolkit that maps raw video directly to behavior, no pose estimation required. It works across species, from lab to field, and even in collective systems. (🧵1/n)

This is a very interesting paper but the empirical evidence presented for an increase in connectivity (in their Fig. 1E) is rather problematic. A little thread 👇(1/7):

Is it possible that social media, which promised to connect the world, instead increased polarization? A model of human social dynamics predicts a sharp transition into a polarized state above a certain threshold of social connectivity. In PNAS: https://ow.ly/Gym350XnNW8

Americans are growing more socially isolated and politically divided. Our new paper in Applied Network Science suggests these two forms of disconnection may be linked. People with denser, more connected social networks often feel less partisan animosity. 🧵

When there is a random way to do something, there is a less random way that is better but requires more thought. In this case, regression models that make no sense don't belong in a multiverse analysis. An inferential regression without a causal justification is like an opinion without reasons.
