🧵on my new paper "Synthetic personas distort the structure of human belief systems" w Roberto Cerina I'm v excited about... 🚨 Do synthetic samples look like human samples? We compare 28 LLMs to the 2024 General Social Survey (GSS) to find out + develop host of diagnostics...

This is very timely! We looked into the posting/moderation anomalies last week in the US. Special kudos to @benguinaudeau.bsky.social @solmg.bsky.social and @kengchichang.bsky.social. An outage rather than targeted censorship is what makes the most sense in this case, we’ll stay vigilant.

🎉 We're really excited to be collaborating with our excellent partners on this, as part of WP3 of the What-If Horizon project, hosted at the Observatory. 🎯 Understanding what interventions affect citizen misinformation effects is crucial to build evidence based policy in the area! More insights 🔜

Very happy to have people from our @ldnsocmedobs.bsky.social attend the DSA40 Data Access Days organized by @dsa40collaboratory.bsky.social. With threats to our online and political safety in the rise, access to platform data for independent and academic researchers is more important than ever.

🥰I had so much fun again teaching computer vision and other computational methods to these bright social scientists this week. (Un)supervised classification, image encoding, content similarity, object detection, face detection/analysis, muldimodal modeling, video data, etc., you name it!

🚨New Publication @thejop.bsky.social We study who sets the issue agenda of state policymakers in the US. We find a mixed picture: they respond to shifts in attention by members of Congress, but also to the constituents in their states, particularly their own party supporters.

Lots of voices are concerned about Elon Musk’s attempts to meddle in German and UK politics. The question is: what do people actually make of this? YouGov Germany has some recent data: In both, the public are assessing Musk’s interference negatively. buff.ly/4gkPqxI
