In this new paper w/ @joshcjackson.bsky.social , @nickornstein.bsky.social , @felix-chenwei.bsky.social , & Bolun Sun, we argue generative AI also distorts social learning, but because it optimizes for something different, it distorts in a different direction.

✨New paper out @nature.com ✨ For 8 weeks around the 2024 US election, we randomly assigned 2,000 people to use social media algos we built ourselves. Do engagement-based algorithms amplify intergroup, moral & emotional (IME) content—and does that distort how we see political norms? 🧵🔗 👇

New paper in @commspsychol.nature.com, with @ycleong.bsky.social, Marc Berman, and @joshcjackson.bsky.social! Two-sentence summary: Political pundits often talk as if partisans are divided in how they feel about political issues, as in “Democrats love abortion” or “Republicans hate immigrants.” 1/2

This study finds partisan language to be less affectively divided over political issues than identity labels, suggesting meaningful affective alignment on contentious issues despite partisan animosity. @nwrim.bsky.social @joshcjackson.bsky.social @ycleong.bsky.social www.nature.com/articles/s44...

Our paper on close relationships as microcultures (led by @mrossignacmilon.bsky.social) is a nice example of how cultural evolutionary ideas are beginning to broaden psychological theorizing I highly recommend to cultural evolutionists who are interested in psychology, or vice versa!

In a new preprint on Relationships as Microcultures Theory, @emmamiller.bsky.social , @lydiaemery.bsky.social , @joshcjackson.bsky.social , and @elijfinkel.bsky.social and I propose that these everyday idiosyncrasies are far from trivial – they are the relationship itself. 2/

Thrilled to share our latest paper, out now in Science Advances! We explored the development of cooperative behaviors — fairness, trustworthiness, forgiveness, & honesty —  across five societies, culturally contextualizing them & seeing how they correlate. (1/5) www.science.org/doi/full/10....

We're excited to announce the first Mind & Machine Alignment Summit at Ohio State! Join leaders from social science and the AI industry to advance AI that promotes well-being and aligns with human values. Learn about emerging work and connect with leading researchers and builders.

Before the end of this year, I’m glad to share a short perspective/policy piece, recently out with @joshcjackson.bsky.social , Zhao Wang, and @williambrady.bsky.social: “Large AI Models Have a Prioritization Problem: Policy Implications and Solutions.”

Americans are growing more socially isolated and politically divided. Our new paper in Applied Network Science suggests these two forms of disconnection may be linked. People with denser, more connected social networks often feel less partisan animosity. 🧵
