I'm honored to be elected an APS fellow! 🥳 Thanks to those who nominated me. @psychscience.bsky.social www.psychologicalscience.org/members/fell...

Proud of Lindsay Ackerman for presenting new data on responsibilism and romantic relationships at SPSP! @spspnews.bsky.social #SPSP2026

Richard Homenya presents an odd finding: why do cultures in sub-Saharan Africa score lower than the West on collectivism? #spsp2026 @spspnews.bsky.social

“Which town do you think has more prejudice? I bet you have a pretty strong intuition,” says Keith Payne. @spspnews.bsky.social #SPSP2026

Yangyilin Guo presenting on regional personality in Colombia, Japan, and New Zealand. 🇳🇿 @spspnews.bsky.social #SPSP2026

This shouldn't be happening! As more and more people leave farms for cities in China, why would rice-wheat differences be increasing? I'll offer an explanation today at 9:30-10:40 AM Room E450B. Stop by! #SPSP2026 @spspnews.bsky.social

People aren't idiots! The biggest problem in cultural psychology for the last 30 years is *by design*. That's what I'll argue today from 2-3:10pm E350. Join me! @spspnews.bsky.social #SPSP2026

Thanks to everyone who helped make the culture pre-conference a “successful failure!” We didn’t make the main pre-conference time, but we had a packed house and a great time. #SPSP2026

Gender polarization increases with gender equality, finds Kodai Kusano, culture pre-conference #SPSP2026

Hello from the Culture Pre-Conference! 👋 #SPSP2026

Are SPSP'ing this year? Join me Friday! I'll explain the two elements that predict whether survey items "work" across cultures. On their own, each element is weak. But with powers combined, they explain much more! Fri. 2-3:10pm Room E350. @spspnews.bsky.social #SPSP2026

Seen at UCLA: PhD students wishing for good fortune, Science, and Nature! 😃 Happy lunar new year! 🧧 @uclaanderson.bsky.social

The best way to change people's behaviour? Pay them! At least, in WEIRD countries. Elsewhere nudges would seem to have the edge. @thomastalhelm.bsky.social explains why it is important to look at culture to pick the most effective intervention: buff.ly/FNDhanl

Someone on Reddit posted about the rice theory, and it generated a lot of buzz! What a feeling to have your dissertation get people interested in research. 🤓 The only downside I see is the poster demoted it from theory to hypothesis. Fair! 😆https://www.reddit.com/r/todayilearned/s/s0ltdiwdwf

Interesting to think about prevention vs. promotion focus as applied to romantic relationships. Jealousy = protect relationships from threats. journals.sagepub.com/doi/abs/10.1...

Neat finding: When startups advertised a job as having more freedom, they got FEWER applications! More and more companies are mentioning autonomy in their postings (especially startups).

I was happy to get the chance to present at UNLV Lee School of Business about how AI misunderstands China (even Baidu's AI!). Also happy to enjoy sunny and 60F compared to 19F in Chicago. 🥶 @unlv.edu

Very cool post-doc opportunity at the University of Arizona. Includes fieldwork in Nicaragua!

MacGyver seems a lot manlier than me, but I did strap together a DIY air purifier that somehow became a global social enterprise! 🤓

It's not about the money! (Especially in Hindi) I did an interview about why money is more powerful in the US than China or India. I also point with both fingers! 😆 youtube.com/watch?v=JuJx... @chicagoboothreview.bsky.social

Thanks to the University of Arizona for hosting me for a research talk! Coming from Chicago, I can’t complain about seeing the sun in January! ☀️ @uarizona.bsky.social

Great post-doc opportunity in Tucson! If you get this, enjoy some hikes in my honor. 😃

Ever tried to get data from a PDF graph? I've been shocked at how bad ChatGPT is at it sometimes. This tool might be better! 💪

If you want to know how to make things better, you need to understand culture. www.chicagobooth.edu/review/cultu...

Using a new study, researchers created this website of the personalities of people in different careers. You can check out those personalities and even test yourself--neat! apps.psych.ut.ee/JobProfiles/

Very cool large-scale study in Niger about how to make interventions more effective. I loved seeing the predictions of Americans versus the data from Nigerian. One strong divergence: respecting others. www.pnas.org/doi/10.1073/...

In our recent study, we found that young people in Mainland China are bicultural. But their parents' generation does not. bpspsychub.onlinelibrary.wiley.com/doi/10.1111/...

It's wild that Project Implicit could shut down. It has provided a rich trove of data on questions like societal change in time in attitudes. Consider donating money to keep this data source alive! 💪

New study finds LLMs can predict how well scale items will correlate with each other in human samples. That's neat! But r = .59 leaves a lot of room for disagreement. That's 35% overlap, 65% disagreement. journals.sagepub.com/doi/10.1177/... @sagepub.com

Do cities make people think WEIRD? Our answer might surprise you. We tracked 1,400 teenagers as they moved across China—some to giant cities like Shanghai, others to small towns like Zhoukou, Henan. bpspsychub.onlinelibrary.wiley.com/doi/10.1111/...

How clever! 👏

Are stress dreams actually adaptive? Researchers surveyed medical students around an important exam...

When governments spend money, it boosts the economy. But why is it less effective in rice cultures?? 🍚 One possibility: more prevention oriented, tend to save, which blunts effect of stimulus. tandfonline.com/doi/full/10....

I do this by NOT keeping cookies or candy at home, knowing I'll eat the whole bag at once. @angeladuckworth.bsky.social www.nytimes.com/2025/12/28/o...

Can someone explain the logic of charging $35 for the first bag, $45 for the second bag, then $150? I'm not trying to check three bags, but that's an insane price jump! 🤯 #SouthwestAirlines

Merry Christmas from East Lansing, Michigan, where even the porta potties are in the holiday spirit. 🎄

New paper out today! The most cost-effective nudges in the US and UK are NOT the most cost-effective in China, Mexico, or India. journals.sagepub.com/doi/10.1177/... @sagepub.com @casbsstanford.bsky.social @chicagoboothreview.bsky.social

Helpful thing to know if you have an air purifier! Don't change the HEPA unless it's very black.
