🚨✨ 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.

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.

Summary of design and results from our three studies. (A: Design) Each study used a similar experimental design, measuring both positive and negative demand in an online experiment, with three commonly-used task types (dictator game, vignette, intervention). Our experiments had ns ≈ 250 per cell. (B: Results) Observed demand effects were statistically indistinguishable from zero. The plot shows means and 95% confidence intervals for standardized mean differences derived from frequentist analyses of each experiment and an inverse variance-weighted fixed-effect estimator pooling all experiments (solid bars). Prior measurements of experimenter demand from a previous dictator game experiment (de Quidt et al., 2018; standardized mean difference from regression coefficient) and a meta-analysis primarily including small-sample, in-person studies (Coles et al., 2025; Hedge’s g statistic) are also shown for comparison (striped bars). The main text includes Bayesian analyses that quantify our uncertainty.

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)

ggplot2 4.0.0 A new major version of ggplot2 has been released on CRAN. Find out what is new here.

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!

Can We Fix Social Media? Testing Prosocial Interventions using Generative Social Simulation Social media platforms have been widely linked to societal harms, including rising polarization and the erosion of constructive debate. Can these problems be mitigated through prosocial interventions?...

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.

Very cool! Thanks for the update :) I'll check it out!

🧠 New Preprint | The concept of reflection in the work of John Dewey

The worst happened. We were DOGE’d. Our NSF funding is gone.

So now there’s nothing stopping me from sharing Expert Voices Together, a crisis response system for US-based researchers and journalists facing harassment.

It's a true passion project. 🧵 1/

it's of course totally fine if not (I understand you're developing a wider ecosystem of packages for text analysis) – just wanted to let you know about this tradeoff :)

Sorry for hijacking this, but would it be possible to remove the dependency to the topics package (requiring rjava)? I planned to use the text package in a class I'm teaching, but opted not to simply because getting students to install rjava on their devices added another layer of complexity

Version 1.5 of the #r-text package is now available from #CRAN.

This version improves the application of pre-trained language assessments from the #LBAM-library (r-text.org/articles/LBA...).

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.

YouTube removes 'gender identity' from hate speech policy TariffTokers, Gen Z’s ‘it couple’, Easter potatoes, anti-MAGA hats, Zuck's D.C. mansion, Amazon's TikTok bid, Silicon Valley's cupid, and the fastest growing political channels on YouTube

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!
