When people seek guidance from science, they expect it to work more than once. I have TWO new articles on commercial forces & proprietary models that make science less reliable, with pointers to communities and ideas that might help. This post offers a summary: citizensandtech.org/2026/07/comm...

New Studies: How Commercial Forces Make Science Less Reliable

Computational social science has been distorted by commercial forces, and AI is making it worse.

Unfortunately, I can’t make it to #IC2S22026 / #IC2S2 this year, but I hope everyone attending has a great time! For those of you working with Prolific or similar participant platforms, our working paper may be relevant. Maintaining high data quality in CSS will continue to be a major challenge.

danah boyd recently argued that social media (as we knew it) is mostly dead; what we have now is parasocial media: journals.sagepub.com/doi/10.1177/... I agree. Networked social media is disappearing, replaced by a new logic/structure of content creator, creator-centered community, & algorithm.

Social Media Is Now Parasocial Media - danah boyd, 2026

When practitioners used the term “social media” to describe the internet tools that emerged in the mid-aughts, they were giving a name to the kinds of platforms...

Early in my PhD, a colleague finishing his (highly rated) dissertation told me he was stuck on the introduction. After years of hard work, he could no longer find an argument for why any of it actually mattered. This stuck with me ever since. A🧵 about this paper: www.nature.com/articles/s41...

Do researchers share their code upon request? Does running their orginal code on the original data produce the original results? We provide evidence in a new Royal Society Open Science publication. Studying more than 1,000 articles which use data from the European Social Survey, we find that... 🧵

Very happy to share that I am going to be the new Director of the Democracy unit at the @wzb.bsky.social Berlin Social Science Center. I am excited to form a new research unit on democratic politics and to engage with people in Berlin and elsewhere to make liberal democracy more resilient.

Another paper I came across this week in PLOS Computational Biology tackling a key #OpenScience issue in a practical way (journals.plos.org/ploscompbiol...). Together with PLOS Biology's new code-sharing policy (journals.plos.org/plosbiology/...), it really boosts my view of PLOS.

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes! "Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky

Synopsis. Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For

If you haven't done yet, please try Claude Coworker just to get an idea about its capabilities. It took 2 minutes for it to read our paper, provide perfectly running R-code to justify a case selection across 14 countries using Vdem. Produced a 10 pager underlining our case selection.

Super excited to see that somebody finally wrote about this 🥳 If you do research about research, you really need causal thinking (just like when you do research about anything else really).

📣 Our introduction to structural causal models in science studies is now published: doi.org/10.1162/QSS.... @tklebel.bsky.social and I tried to make our introduction as accessible as possible. We illustrate the theory by three case studies based on a simulated model of Open Science. 🧵(1/6)
