Concern with WEIRD cultures and behaviours does not only concern humans. It gets much worse when we look at the animal models and the study of non-human animal cognition, affect, and behavior. Incredibly proud of @jespinosa.bsky.social and colleagues for making this provocative, needed argument.

Would a dog in New York City respond in the same way as a dog in Kyoto? @jespinosa.bsky.social and colleagues address how studies on domestic dogs tend to focus on a Westernized subset.

After three months on the road, I'm finally putting the bags down for a bit — Freiburg, for the next month, on an Alexander von Humboldt Research Award. A short thread on landing here 🧵

"If there is anything that still ails psychology... it is the neglect of investigation of environmental or ecological texture." Brunswik, '57 @bayesandbounds.bsky.social takes that seriously in the new Psychological Inquiry 37:1. Check in out! 🔗 doi.org/10.1080/1047840X.2026.2650209

In the Mind or in the World? Types of Beliefs and the Locality of Evidence

People’s beliefs appear to be divisible into two distinct types. Some beliefs refer directly to the observable world, readily guide behavior, and are easily revised when challenged. Others, includi...

Thrilled this is out! www.tandfonline.com/doi/full/10.... 🧵 Do we have 2 kinds of beliefs? Some beliefs seem insensitive to evidence and rarely guide behavior, etc. To explain this, several theories divide belief into 2 types. I argue the explanation isn't in the *mind* but in the *world*

1/ We've been measuring intellectual humility wrong. Most scales ask "are you intellectually humble?" but the people least humble are the most miscalibrated about it. They overclaim. The #humilityparadox. Out today in Behavior Research Methods. Here's what we did instead. 🧵

Intelligence is processing 10,000 transactions a minute. Wisdom is knowing which 3 failed. 3 weeks in India. 7 talks on AI, metacognition, and wisdom under radical uncertainty. What I learned — and what the audiences taught me. 🧵

1/ NEW in Advances in Experimental Social Psychology — our first review of a decade+ of research on understanding & predicting cultural change, with Michael Varnum. This one is personal. A thread on what we found, what surprised us, and how two kids reading Asimov ended up here. 🧵

Recently got 5 excellent reviews on a paper. Super thankful — four reviewers clearly put real thought into strengthening the work. The problem: Reviewer 2 (of course!) was, by every available indicator, substantially generated by a large language model. 🧵

1/12Wisdom isn’t just a trait or a mystical aura. It’s a metacognitive & cultural process. In a new preprint, we propose a new synthesis at the intersection of Cultural Evolution and Cognitive Science, mapping how to judge, think, and survive in an age of uncertainty. 🧵

Can we predict the past? 🔮 New open-access paper in American Historical Review proposes 'Retrodiction'—using gaps in the archival record to test historical theories. Interdisciplinary collab feat. David Gill, Marc Trachtenberg, Phil Tetlock, Cendri Hutcherson, and more 🧵👇

🚨 New Paper Alert 🚨 "Understanding & Predicting Cultural Change" is accepted at Advances in Experimental Social Psychology! Varnum & I argue that Psychology cannot afford to be blind to time. We need to move from cross-sectional snapshots to dynamic time-series movies. 🧵👇

International students: Were you told "no" to Waterloo recently due to recruitment bans? The door just swung back open. 🚪🔓 Canada just launched the Impact+ Research Training Awards (CIRTA), and my lab is looking for the best global talent to join us. (1/4)

Wrapping up the year feeling very grateful for the brilliant team at the Wisdom & Culture Lab (plus alumni!). End-of-term outing to Toronto’s St. Lawrence Market + the Distillery District—great convos, great company, great snacks. Happy Holidays! 🎓✨🍁
