NIH funding cuts could cost the U.S. $16 Billion and 68,000 jobs. An interactive tool from Joshua Weitz and team shows the local impact across the U.S. - down to the county level. This isn’t abstract - these numbers affect real communities and real lives: scienceimpacts.org

Yes I think the backstory here is that Harvard leadership really did want to try to work something out without litigation but univ leadership basically felt this last round of Trump demands were beyond the pale This letter leaves Harvard with no choice

At this precarious moment for universities, I am proud of the non-partisan research we do at Yale ISPS to better understand American public opinion. Even Elon Musk wants to cite research produced by Yale University Yale Poll

On 4/25, NSF told MikeCrespin, Kosuke Imai, and I that our project was axed. Still wanted to celebrate our 1-month anniversary. Since going live on 4/1 our data (dataverse.harvard.edu/dataverse/ctap) has been downloaded 11,552 times. Thanks! Keep downloading! Paper: doi.org/10.48550/arXiv…

People have no idea of the extent of the destruction happening in the scientific community. There is no real-time feedback loop like the stock market. But, man, are we shooting ourselves in the foot. Decades to build; months to destroy.

Across the country, there is growing momentum among states to support local news, not as a bailout but as essential civic infrastructure that communities can’t afford to lose. via Jon Allsop at The New Yorker newyorker.com/news/fault-lin…

Researchers Univ. of Maryland are examining how and why some misleading narratives proliferate via strategic use of certain mainstream news articles. The paper—coauthored by Pranav Goel, Jon Green, 🇺🇦 [email protected] & Philip Resnik—was published Nature Human Behaviour. nature.com/articles/s4156…

New CHIP50 report on public approval of government interventions in science -- funding cuts, mass layoffs, etc. On average, over twice as many Americans disapprove of these actions as approve.National Academies AAAS Science News Scientific American Science Magazine International Communication Association chip50.org/reports/americ…

Average approval of science-related government actions is highest among Republicans (42%), men (28%), graduate degree holders (30%), and high-income respondents (31%). Disapproval is strongest among Democrats (74%), African Americans (56%), women (53%), and those aged 65+ (55%).

People were more likely to believe in conspiracy theories about the attempted assassination of President Trump if they heard them from people they knew than if they heard them on social media, according to a study. In PNAS Nexus: ow.ly/JlPs50Wmseo

How does social network structure amplify or stifle behavior diffusion? Turns out, complex contagions are more complicated than we thought … (1/7)

Even with strong social reinforcement random networks spread behavior better than clustered networks. Clustered networks outspread random networks in only a small region of the space we model and mostly only when behavior is near deterministic (4/7)

The basic pattern is a tradeoff: reaching more people via random ties or exploit social reinforcement via clustered ties. Paper with Allison Wan 🇺🇦 [email protected] Christoph Riedl (7/7) pnas.org/doi/10.1073/pn…

Here's a treat for state politics and policy researchers. Ethan Dee and I published a dataset in Nature: Scientific Data with 1.36 million state legislative bills since ~2009 coded by 28 policy areas. We used a machine learning model built off open source components.
