Two sets of faces bounded by a green box (left) and a red box (right). Faces in the left, green box were generated by egalitarians, faces in the right, red box were generated by anti-egalitarians

New work on resource possession + hierarchy regulation!

Do the faces on the left and right look different to you?

They were generated using a reverse correlation task by UK ps asked to visualize “poor people”:

🟩 Generated by egalitarians (low SDO)
🟥 Generated by anti-egalitarians (high SDO)

I had a great time at HBES 2025 @humbehevosoc.bsky.social! I presented my work on a method we developed that allows us to predict who people will choose as partners 3 months into the future—participants chose romantic partners on their own, in their own mating markets—with zero intervention from us!

Another badge for the collection! Had a great time at #HBES2025 :) 📍Atlantic City, NJ

Optimism and health: Resource or delusion? Bill Chopik Michigan State University March 31, 2025 at ISR Thompson 1430

🤗 This *will* be a great talk! @chops310.bsky.social joins @rcgd-isr.bsky.social and the Katz-Newcomb colloquium series to give a crash course on optimism, where it comes from, and whether it's a source of resilience or delusion. events.umich.edu/event/134094 @daviddunning6.bsky.social

For the final project in my "Shamanism & Witchcraft" course this past quarter, I gave students a huge amount of freedom: any medium, any tech (including as much AI as they needed), as long as they explored content from the class. I love what they produced.

Here's a selection:

(PDF) Ho, Kteily, Sheehy-Skeffington, and Thomsen, Social Dominance Orientation, IN PRESS AESP PDF | On Mar 21, 2025, Jennifer Sheehy-Skeffington and others published Ho, Kteily, Sheehy-Skeffington, and Thomsen, Social Dominance Orientation, IN PRESS AESP | Find, read and cite all the research ...

Ho et al. (2025) review three decades of work on social dominance orientation (SDO), which represents "individual differences in the preference for group-based hierarchy and inequality."

Today at 4pm, EHAP is excited to welcome Annie Wertz to our speaker series. Please join us for her talk on infants & plants!

Last, some highlights from the #EPatSPSP2025 datablitzes:

1) A seriously cool talk by @wnmerrell.bsky.social about how we infer clustered (patchy) resource distribution based on an area’s hierarchicalness (& vice versa). Who knew lobstering could be so socially complex?! #SPSP2025

Next up, @joshackman.bsky.social reminded us that disease remains a potent threat post-pandemic, and has been throughout human history - to the point that we’ve got psychological mechanisms dedicated to preventing and coping with it. (1/5) #EPatSPSP2025 #SPSP2025

Lots of lab member content at #SPSP2025! Posters from @kaelynsabree.bsky.social on "Ecology-driven Stereotypes," Savannah Adams on "Moral Judgments of Concealers of Infectious Illness," and Nicole Li on "Cultural Variations in Emotion Regulation through the Body: the Role of Cognitive Styles"...

Presentation title, time, and location. Mapping conflict: How spatial resource patchiness shapes perceptions of territoriality. Thursday 20 February 2025, 9:15 - 10:00. Blueburd ballroom

Presentation title, time, and location. Patchy resource ecologies can evoke intergroup conflict. Thursday February 20, 16:30 - 17:00. Four seasons ballroom

Whether we're foraging for food or hunting for houses, humans expect resources to be clumped. What are the implications of this'patchiness psychology' for intergroup relations? Excited to share new geospatial approaches tackling this❓at #SPSP2025 this week--stop by and say hi if you're in town!
