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.

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!
When you collect data online, are the results from humans or AI? In a project led by Booth PhD student Grace Zhang, we estimate the prevalence of AI agents on commonly used survey platforms:

Chart showing change in the use of online platforms. Over the past few years, four of them have grown in overall use among U.S. adults – TikTok, Instagram, WhatsApp and Reddit. TikTok: 37% of U.S. adults report using the platform, which is slightly up from last year and up from 21% in 2021. Instagram: Half of U.S. adults now report using it, which is on par with last year but up from 40% in 2021. WhatsApp and Reddit: About a third say they use WhatsApp, up from 23% in 2021. And 26% today report using Reddit, compared with 18% four years ago. While YouTube and Facebook continue to sit at the top, the shares of Americans who report using them have remained relatively stable in recent years.
UPDATE: Americans who use
YouTube 84%
Facebook 71%
Instagram 50%
TikTok 37%
WhatsApp 32%
Reddit 26%
Snapchat 25%
X (Twitter) 21%
Threads 8%
Bluesky 4%
Truth Social 3%

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.
