A journalist asked me about public behaviour during the Bondi Beach attack:

A common problem w/ studies testing non-WEIRD groups is they compare multiple groups using the same WEIRD measure. How can we compare groups w/ apples-apples measures w/o distorting cross-cultural differences? We explore this in this new paper! onlinelibrary.wiley.com/doi/10.1111/...

🚨 Call for abstracts 🚨 Join our EASP pre-conference on 'Prosocial and Antisocial Behavior: Cross-Cultural Perspectives and Methods' on June 30, 2026. We invite flash talk submissions from researchers at all career stages. 📝 Deadline: January 5 2026 🔗 More info: docs.google.com/document/d/1...

There are 10 (!) #PhD positions available through the ECCO project (which our colleagues Lise Jans and Ellen van der Werff are part of) on #sustainable transitions - deadline to apply is 15 February: www.collectievekracht.eu/ecco/ecco+pr... @collectievekracht.bsky.social

🚨STOP, replication time!🚨 Does Feeling “Right” Make the Good More Good (and the Bad More Bad)? Achar & Lee found that when people experience regulatory fit, moral predispositions get amplified—moral folks act more moral, less moral folks act less moral. Big, exciting claim!

🧠💡 This feat of study by Kasper Otten and colleagues analyzed 1.5M decisions from 135K people in online public-goods games. Takeaway? When group membership changes (people leave, newcomers join), cooperation drops. Stable groups = stronger cooperation. www.nature.com/articles/s41...

📣 Excited to share new work led by @anneleh.bsky.social and Star Hartley in @spssi.bsky.social's Journal of Social issues! We report studies w/ indigenous iTaukei and Indo-Fijians (displaced under colonial rule) investigating how each reasons about equal rights and democratic governance in Fiji.

"What makes Sudan's crisis even more alarming is its invisibility. The world is not watching closely enough" The Sudanese civil war is creating the world's worst humanitarian disaster with 12 million people now displaced This 🧵traces the deep connections b/w this conflict & the #ClimateCrisis 1/n

🚨 SynthNet is out 🚨 Researchers propose new constructs and measures faster than anyone can track. We (@anniria.bsky.social @ruben.the100.ci) built a search engine to check what already exists and help identify redundancies; indexing 74,000 scales from ~31,500 instruments in APA PsycTests. 🧵1/3

This—on my former university, department, and advisor—is harrowing but required reading for all social psychologists. www.bloomberg.com/news/feature...

"Multiple men have remained in senior roles at Oxford for months or years after allegations of sexual misconduct emerged against them, Bloomberg found in a nine-month investigation based on interviews with almost 50 people as well as documents and other records."

Should 'sisters' be doing it by themselves when it comes to gender equality initiatives? Not really, no! "It [also] matters whether the approach is arguing for a 'we-change' or a 'she-change'.” Open Access: doi.org/10.1111/pops... BSky author: @shellkryan.bsky.social

New review from me on whether there are ideological differences in science denial. Although Dems/libs are much more likely to report they trust science than Reps/cons in the U.S., similar diffs do not emerge in most countries, and in some, it's the reverse. www.sciencedirect.com/science/arti...

Empathy for deep-sea animals as a twofold empathy problem: empathy for physical form dissimilarity, and across divides of the unknown (i.e., ecologies about which we know little). Can curiosity offset empathy avoidance and foster approach? @psuliberalarts.bsky.social @ssripennstate.bsky.social

Posting is correlated with affective polarization: 😡 The most partisan users — those who love their party and despise the other — are more likely to post about politics 🥊 The result? A loud angry minority dominates online politics, which itself can drive polarization (see doi.org/10.1073/pnas...)

Every academic career is built on rejection, but we don’t show it. 
CVs list publications, grants & awards, not rejected manuscripts, unfunded proposals, or failures. 
But those invisible rejections shape us more than our successes ever do. 👉 catherineeunicedevries.substack.com/p/fail-bette... 🧵

Why do we derogate effective altruists, activists, & other radically prosocial individuals? In new work, we discuss how doing good that deviates from social norms gets stigmatized. New preprint w/ @dcameron.bsky.social @tlau.bsky.social @desmond-ong.bsky.social: osf.io/preprints/ps...

This game by @financialtimes.com shows the positive results of high impact (and high effort) sustainability measures, yet mostly overlooks the role of behavior change (with only a few solutions involving personal action). System change and behavior change are both crucial ig.ft.com/climate-game/

Shared my insights about a Broken Social Scene album that is not as good as You Forgot It In People but is still pretty dang good

Jane Goodall has died. She was truly a beacon of light in this world. I had the good fortune of seeing her speak shortly before COVID arrived. She showed such warmth, compassion, integrity, and intelligence. Jane, the animals thank you for your selfless work. www.nbcnews.com/news/obituar...

The world has lost its most powerful advocate for nature and hope. Yet many remain who will continue her legacy and I know she will continue to inspire generations more.

🚨 Excited to share our new paper in @nathumbehav.nature.com! In a cross-societal online behavioural experiment with 3,371 participants in 13 societies, we found that perceived societal honour norms predict both greater competition and greater cooperation. 🔗 www.nature.com/articles/s41... 1/9

This review suggests that the average effectiveness of choice architecture interventions on behaviour is smaller than often reported and that there is substantial heterogeneity in their effects @szaszibarnabas.bsky.social www.nature.com/articles/s44...

"Progress in theorising means treating our theories as works in progress in need of continuous improvement, and this sometimes also means having to kill one’s darlings." Martijn van Zomeren and @ayseuskul.bsky.social introduce the ERSP special issue on theorizing in social psychology. #SocialPsyc

Did you know that people who move to more walkable cities in the US end up walking more? This seems obvious, but is quite solid evidence for the influence of the built environment on human activity and well-being. Read more in the @nature.com paper here: www.nature.com/articles/s41...

Major new paper by finds implicit measures like the IAT are no better than asking people directly about their biases. After decades of avoiding self-reports, turns out our sophisticated replacement tools work no better than what we abandoned. New post!
