🚨✨ Publication alert: How do people in 6 countries (🇬🇧 🇺🇸 🇫🇷 🇦🇷 🇩🇰 🇯🇵 ) use AI 🤖 and think about it in the context of information, news, and institutions? Our new @reutersinstitute.bsky.social survey research (n ≈ 12,000) with @richardfletcher.bsky.social & @rasmuskleis.bsky.social explores this.

Very excited to announce the next term of the TADA speaker series! This term revolves around the validity of LLM generated data in the Social Sciences. We have a set of four great speakers to enlighten us on different aspects of this issue. If you'd like to join, sign up here: TADA.cool

Great to see this out! With @bsky.charispapaevangelou.eu we analyse the DSA “Statement of Reasons” database, the EU-mandated archive of moderation decisions by online platforms. We examine what kind of platform observability the database affords & find large regional and cross-platform differences.

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Looking for help from #psychology and #survey folks who study #politics and use Prolific to collect data What is the maximum for # of GOP participants one can plausibly get? According to the prescreen there's 10-12k GOP/leaners, but of course what's realistic for uptake is much lower. Thank you!

We built the simplest possible social media platform. No algorithms. No ads. Just LLM agents posting and following. It still became a polarization machine. Then we tried six interventions to fix social media. The results were… not what we expected. arxiv.org/abs/2508.03385

The mods of r/ChangeMyView shared the sub was the subject of a study to test the persuasiveness of LLMs & that they didn't consent. There’s a lot that went wrong, so here’s a 🧵 unpacking it, along with some ideas for how to do research with online communities ethically. tinyurl.com/59tpt988

🎉 Effects of climate protests by scientists paper published! Our findings suggest that scientists can engage in public protest without compromising their credibility, but that such actions alone may have less impact than one would like to believe: royalsocietypublishing.org/doi/10.1098/...

Okay, I'm not done yet but I have been instructed to head to the #EuroCIM2025 student mixer and I guess you get the idea. I've been struggling to explain this in talks just working with the equations; I think the figures should make it a lot easier to follow along.

SCOOP: YouTube removes 'gender identity' from hate speech policy. "YouTube quietly removing ‘gender identity and expression’ from its list of protected groups is a major radical shift away from best practices in the field of trust and safety."

Super cool work shining light on some yet underexplored but super important factors driving who speaks and who remains silent on in online conversations!

As Germany gears up for its parliamentary elections on February 23, I’ve analyzed digital ad spending trends from 2021 to 2025. TL;DR: ad spending increased but that is mainly due to a shift to Google. Click through the thread below or check out my blog post ⬇️ www.favstats.eu/post/btws/

A while coming, but happy to say that `parttree` is finally on CRAN. #rstats #dataviz Visualize simple decision tree partitions on the scale of the data. Useful for getting an intuitive sense of how your model has carved up the feature space. Works for both classification & regression tasks. 1/2

NEW: I've obtained internal Meta docs revealing an array of sample posts that are now allowed under new hate speech rules. Examples include calling children "trannies," “Jews are flat out greedier than Christians," and “immigrants are grubby, filthy pieces of shit” theintercept.com/2025/01/09/f...

Folks are mostly missing the forest for the trees re: the recent Meta announcement. Specifically, the focus on the move from fact checking to community notes. There two different changes that are a much bigger deal that have received less focus. 🧵 1/11
