Our new paper in PNAS Nexus. County morals > politics for carbon footprints? 🤯 We find that county-level values predict actual green behavior (emissions!), not just attitudes. Stronger than political leaning.
A study finds that moral values predict environmental action as well as or better than political party affiliation. US counties where residents prioritize purity and fairness report higher environmental concerns and lower carbon emissions. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

New research led by @zhpinkman.bsky.social investigating the impact of LLMs on the reduction of linguistic diversity and its societal implications.

"We're getting the language into its final shape - the shape it's going to have when nobody speaks anything else." George Orwell, 1984
How do LLMs shape writing? Our research shows they make language more uniform, reducing diversity and altering how personal traits appear in text. These shifts have big implications for identity, culture, and fairness.
