Glad to see this WP from our lab out today, a labor of love over last year. Kudos to @davidbroska.bsky.social and @jonnekamphorst.bsky.social for their hard work on it! Please share any comments, suggestions, or criticisms of the research. All are welcome!

Thanks to Jonas Schoene for sharing his work on how people judge the immorality of organizations! @robbwiller.bsky.social

Americans say they want less inequality. Why don’t they support policies to reduce it? New paper: across 31 nationally representative survey waves (N=384,248) and a preregistered experiment (N=1,009), Americans favor PREdistributive over REdistributive policies 🧵 osf.io/preprints/so...

Thanks to @davidbroska.bsky.social for sharing his new methods for simulating social science experiments! Stay tuned for more in the coming months👀 @robbwiller.bsky.social

Climate change impacts are here, but public support for action remains polarized. Which climate messages move people? In a ~13,500-person megastudy, we tested 10 of the most-cited messages. Six increased pro-environmental attitudes in the U.S.—but only by 1–4 percentage points. 🧵

Can AI voter guides help voters decide while remaining accurate, nonpartisan, and trustworthy? Very grateful to @stanfordimpactlabs.bsky.social for a new grant supporting our next work on this (building on work led by Joe Mernyk & Jonne Kamphorst): bsky.app/profile/robb...

Many wise insights from Gov Spencer Cox & @ezraklein.bsky.social Gov Cox rightly notes his 2020 video w Chris Peterson was among most impactful in Strengthening Democracy Challenge, a striking example of cross-party engagement. Grateful for their commitment. Hear it: 👇 youtu.be/WJB87niNCk0

It is great to see Gov Spencer Cox stepping up to turn the temperature down and focus ppl on grieving the tragic killing of Charlie Kirk. Gov Cox has long promoted civility across party lines. Our research finds that his messages are persuasive when Americans see it. 👇

Does labeling AI content affect its persuasiveness? Our latest policy brief evaluates the impact of authorship labels on how people perceive AI-written policy messages. @jurafsky.bsky.social @robbwiller.bsky.social @federicobianchi.bsky.social hai.stanford.edu/policy/label...
