For folks interested in learning about our lab's research, check out this flier with all our presentations at this coming #SPSP2026 conference @spspnews.bsky.social. With research by several rising stars covering tech, culture, politics and more Credit to our talented lab manager Hanying Yao!

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. 🧵

What happens when we model the detective archetype at scale? 🕵️‍♂️📚 Our new paper, accepted for #CHR2025 combines literary history and computational modeling to trace how the figure of the detective evolves across 150 years of French fiction. arxiv.org/pdf/2511.00627

Adam Smith wrongly predicts that celebrity wages will drop once people begin to like celebrities (Wealth of Nations was published in 1776)

How do humans keep inventing tools and technologies that no single person could create alone? Our new preprint, led by @anilyaman.bsky.social & @ts-brain.bsky.social shows that semantic knowledge guides innovation and drives cultural evolution. 🧠📘 arxiv.org/abs/2510.12837

🚨New preprint🚨 osf.io/preprints/ps... In a sample of ~2 billion comments, social media discourse becomes more negative over time Archival and experimental findings suggest this is a byproduct of people trying to differentiate themselves Led by @hongkai1.bsky.social in his 1st year (!) of his PhD

One of my favorite conferences, @culturalevolsoc.bsky.social, just released key dates and other info! I highly recommend checking it out for great research from across the social, behavioral, and natural sciences

🚨 New paper alert! (slightly belated) We (with @joshcjackson.bsky.social) suggest that complex technologies, as they need several (often many) people to use them, require innovations that distribute cognition to help regulate cognitive load and coordinate. www.sciencedirect.com/science/arti...

Below is my new post about our Three Stages of Religious Decline paper (www.nature.com/articles/s41...). We argue that a similar process of decline affects countries on every populated continent, including countries in which Christianity, Islam, Buddhism or Hinduism is the largest religion. A🧵

@helenamiton.bsky.social and I have a new paper out: www.sciencedirect.com/science/arti... Past theories focus on how we evolve complex technologies (jet engines), but neglect cultural innovations that help us operate these technologies (pilot checklist) Paper has tons of examples and new theory!

Social media often feels saturated with politics and morality - but is that feeling accurate? Our new paper finds that moralization has increased markedly on social media from 2013-2021, more than traditional media. See 🧵 below!

One of the largest-scale analyses of historical text data that I have contributed to The finding: language on social media has become more moralized over the 21st century; we don't see the same trends on news media Kudos to the first author @curtispuryear.bsky.social on the enormous effort

English language is filled with trait words like “caring” and “smart” These words are the currency of personality/social psych, yet key questions remain about their evolution, function, and structure We take on these questions in a preprint led by @yuanzeliu.bsky.social osf.io/preprints/ps...

Look what you could publish (anonymously) in Nature in 1970.

If anyone is submitting to SESP and looking for a speaker to complete their symposium, I have a collaborator doing really interesting work related to culture, income, and social cognition. He has multiple cool projects on all of those topics. Feel free to message me and I can connect you

I'm disappointed to share that my NSF career grant on anti-Asian dehumanization was terminated. This affects ongoing project activities, which have shown great progress so far, and support for my research team and more. I'm sad to share that the hiring of the postdoc role is currently on pause.

This paper is now published. www.nature.com/articles/s44...

This was a really interesting project to be part of, and cool use of causal methods to study a big societal question. I recommend reading the preprint, and looking at our last theoretical paper (linked here) that generated the predictions tested in this paper.

My first PhD project is out there. Thank you to my advisor @psmaldino.bsky.social and to mentor, co-author and friend @babeheim.bsky.social for encouraging and helping build this exciting and insightful collaboration. Onwards!
