🚨Preprint alert🚨 How does affective polarization change democracy? Lots of pubs study how AP affects trust, democratic norms, inter-partisan attitudes, and participation. We (w/ @polpsychjoe.bsky.social, @lilymasonphd.bsky.social) examine a vital assumption this research seems to rely on: 1/6🧵

Folks who stand up for and defend democracy and democratic principles and institutions are sometimes faulted for being nostalgic and conservative. I honestly don’t know any “democracy defenders” who don’t believe that all kinds of existing democracies cannot and should not be improved.

💡DDCxTrygFonden Update💡 The Anti-Autocracy Handbook: The Scholars’ Guide to Navigating Democratic Backsliding has just been published by a team of researchers, including our former TrygFonden Fellow Konstantinos Armaos. Access it here: sks.to/autocracy

Someone is getting the Royal treatment #NATOSummit

NL picks up the Danish model: paying efficient and advanced Ukrainian companies to produce 600k drones for Ukraine’s own use, thus supporting its economy too. 3 birds with one stone

Very relevant findings for survey research and survey methodology: Attitudes toward democracy and previous survey engagement appear to play a greater role in panel attrition than whether respondents supported the winning or losing side in the last election 👇🏽

BREAKING. Alert 🚨 News users disable notifications from news organizations. Over use by news providers? Part of news avoidance? Result of many simultaneous world crises? “It is definitely alert fatigue” #commsky #journalism www.theguardian.com/media/2025/j...

Very excited to share a new preprint. @jesperasring.bsky.social and I study how politicians engage with evidence in the real world. Link: osf.io/8zv9s

Sad that reporting is needed on how to safely enter 🇺🇸 with electronic devices. Article shows that it is no small feat. A travel phone is an option. But a sanitized version also requires “separate communication and social media accounts created specifically for travel” www.wired.com/story/how-to...

Russian propaganda has infiltrated AI chatbots in the Nordic countries. Four fact-checking groups from @nordishub.bsky.social tested ChatGPT and other large language models (LLMs) in Finnish, Swedish, Norwegian and Danish. They found that these bots sometimes reproduce pro-Russian narratives. 1/5

The Digital News Report shows how the connection between news media and much of the public is fraying in much of the world - but also where it remains strong. In Denmark, everybody uses digital platforms, but several media groups have wider reach when it comes to news politiken.dk/kultur/medie...

Previous studies showed how Republicans share more misinformation. This was disputed by some, blaming fact-checking biases. Enter Community Notes. Guess what: "2.3 times more posts by Republicans are flagged as misleading compared to posts by Democrats." www.pnas.org/doi/10.1073/...

Vor meinem Urlaub hatte ich große Freude daran dem @spiegel.de ein Interview zu geben rundum unsere (mit @rsenninger.bsky.social) Forschung zur einfachen Sprache in der Politik und deren Auswirkung:

@jbgruber.bsky.social kicking off @icacm.bsky.social 's tool demo session, and the best thing is: everything is on github! github.com/JBGruber/ica... - check it out if you need to scrape news or retrieve tiktok data and want sth that just works! #ica25

Lots of interesting takeaways from the MADEU24 project incl finding that the hostile misinformation effect - whereby ppl believe misinformation is mostly directed at their political side- is stronger as political interest party liking, and ideological extremity increases. #ica25
