1/ New @Nature! We study how powerful institutions shape the information environment for LLMs. Commercial LLM training is opaque, so we trace a path from state-coordinated media -> training data -> model responses.

🚨NEW DISINFO PAPER🚨 TLDR; disinformation circulates as narratives, not false facts. This paper took five years (!!!) and a rotating cast of collaborators and GRAs. Our case studies include the pee tape, and we have an entire appendix justifying that. www.tandfonline.com/doi/full/10....

🚀Introducing 𝐆𝐔𝐈𝐃𝐄-𝐋𝐋𝐌: A reporting checklist for using LLMs in behavioral & social science ✅GUIDE-LLM is a reporting checklist designed by 80+ experts to improve transparency, reproducibility & ethical accountability of LLM-based research 📄 llm-checklist.com

Since last year, the US has publicized a visa policy that targets & threatens people who study & report on online harms. Yesterday @knightcolumbia.org & @protectdemocracy.org filed a lawsuit challenging this censorship policy on behalf of @thecoalition.bsky.social knightcolumbia.org/content/tech...

Hi there social psychologists- excited to pop in on SPSP for a workshop in the use of AI in social science tomorrow morning with @mjcrockett.bsky.social @killianmcloughlin.bsky.social & Alexis Palmer. Ping me if you want to say hi!

Last year at SPSP we had some great discussions about research with LLMs. This time #spsp2026 we're back with a whole workshop! Friday 2/27 at 8am, + informal drinks at 6pm to continue the conversation More info, plus a chance to submit discussion topics, here: spsp2026.carrd.co

Interested in why moral conflict is so common on social media? Join us at #SPSP 2026 for our symposium. We’ll present new findings on how platforms shape digital discourse and explore pathways toward healthier online environments 🗓 Saturday, the 28th | 9:30–10:40 AM 📍 Room E270, Level 2

Are you a grad student who wants to give a talk at Princeton’s psychology department (in-person or on Zoom)? Nominate yourself or someone you know: forms.gle/WN2ybYMuZiW3... Priority given to non-Ivy and URM students. International applicants welcome. Deadline is this Friday (Feb 6)!

✨New preprint! Why do people express outrage online? In 4 studies we develop a taxonomy of online outrage motives, test what motives people report, what they infer for in- vs. out-partisans, and how motive inferences shape downstream intergroup consequences. Led by @felix-chenwei.bsky.social 🧵👇

New preprint! We developed new measurement tools to examine moralization in ~2B Twitter/X & Reddit posts and ~5M traditional media texts. Key finding: moralization increased markedly on social media from 2013-2021; more than traditional media; associated with multiple user dynamics 🧵👇

Grateful for the chance to share my thoughts on responsible use of LLMs in psychology research @spspnews.bsky.social #spsp2025. Here's a summary of my presentation for those who missed it. Thanks to @ashwinia.bsky.social for organizing this panel! How should LLMs be used in psychology research? 🧵

👀New preprint! In 3 prereg experiments we study how engagement-based algorithms amplify ingroup, moral and emotional (IME) content in ways that disrupt social norm learning (and test one solution!) w/ @joshcjackson.bsky.social and my amazing lab managers @merielcd.bsky.social & Silvan Baier 🧵👇

How politicians communicate shapes online discourse in ways we might overlook. Our new paper shows that their choice between a fact-based (evidence-driven) and a belief-based (sincerity-driven) honesty creates a "contagion" effect, influencing how users engage and respond. ⬇️(1/8)

Is it Bad to leave Twitter? No. Here are 7+ years of insights from my lab’s research that explain why. Featuring work w/ @williambrady.bsky.social @killianmcloughlin.bsky.social 🧵

New paper out in @ScienceMagazine! In 8 studies (multiple platforms, methods, time periods) we find: misinformation evokes more outrage than trustworthy news, when it does it's shared more + ppl are less likely to read before sharing. w/ @killianmcl1 @Klonick @mollycrockett 🧵👇
