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. 🧵
Scheidel's "Great Leveler" argued equality has historically come from violence. Can peaceful redistribution do the same? In our lab experiment, redistribution doesn't reduce punishment — it shifts it from 'punish the rich' to 'punish free-riders.' 🧵 journals.plos.org/plosone/arti...
Inequality aversion and prosocial punishment: Evidence from a one-shot public goods game
The willingness to engage in costly punishment of free riders (prosocial punishment) is crucial to foster group cooperation and understand public goods provision. While prosocial punishment is common ...

Many think LLM-simulated participants can transform behavioral science. But there's been a lack of accessible discussion of what it means to validate LLMs for behavioral scientists. Under what conditions can we trust LLMs to learn about human parameters? Our paper maps the validation landscape. 1/
🧵1/ Our first meta-science paper (with 350+ coauthors) is published today in Nature. It presents one of the largest-ever reproducibility projects in economics & political science. Here’s what we found 👇
📄Published Today in Nature: 500 researchers reproduced 100 studies across the social & behavioral sciences to assess their analytical robustness (led by @balazsaczel.bsky.social & @szaszibarnabas.bsky.social). Article: www.nature.com/articles/s41... Preprint: osf.io/preprints/me... TLDR: 1/11

Deeply honoured to receive this award from the Academy of Sociology with my co-authors! I hope we’ll see many more replications in Sociology in the years ahead, along with preregistrations and registered reports as leading journals make more space for them. #AkadSoz25 #sociology
And the 1st Replication Award of the Academy of Sociology goes to.. Sergio Lo Iacono, Wojtek Przepiorka, Vincent Buskens, Rense Corten, Marcel van Assen, and Arnout van de Rijt for "The competitive advantage of sanctioning institutions revisited: A multilab replication" #AkadSoz25 #sociology 1/
