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.

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 country’s religious affiliation tends to decline in three transitional stages that unfold across generations, a new paper using Center data proposes.

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!
New preprint! We developed new measurement tools to examine moralization in ~2B Twitter/X & Reddit posts and ~5M traditional media texts.
Key finding: moralization increased markedly on social media from 2013-2021; more than traditional media; associated with multiple user dynamics
