My dad abhors any negative comments about immigrants. Asked him recently why he’s so strong on it: ‘Because we’re always happy to take the rich and clever ones. Which means it’s not about disliking immigrants. It’s about disliking the poor and vulnerable. And that’s a bad human instinct.’

Our new meta-analysis of 1,114 studies on cross-cultural adaptation is now available via Nature Communications! What is it that actually helps immigrants adapt to the new culture? In this paper, we test a number of different adaptation correlates to find out. Check it out! doi.org/10.1038/s414...

UK Metascience Funding "The UK government has announced a major increase in funding for metascience over the next four years, including a more than trebling of investment in the UK Metascience Unit."

Preparing this talk gave me an opportunity to reflect on what lessons I've learned from psychology's replication crisis and credibility revolution, and what advice I would have for other fields. We've come a long way! Video: youtu.be/_vb1CNwC3CM?... Slides : osf.io/cuj62/files/...

📢 The acculturation debate continues: A Direct Response to John Berry's critique was just published in advances.in/psychology! @kbierwiaczonek.bsky.social addresses recent criticisms and reveals crucial, overlooked findings from meta-analytical evidence. advances.in/psychology/1...

This is why we have sample size justifications. Some people might mindlessly dismiss small N studies. But a well justified sample size (see online.ucpress.edu/collabra/art...) defends against such mindlessless.

While re-writing my R tutorials I removed the Bayes material from individual tutorials, rewrote it, and collected it in its own home. Just pushed the resulting tutorial `discovr_bayes` to github, it's a gentle intro to Bayesian estimation using rstanarm. github.com/profandyfiel...

Kicking-off her PhD journey, @wagunyego.bsky.social talked about her initial findings capturing epistemic injustice and its relationship to trust in science. So many interesting avenues to go from here, more exciting stuff coming over the course of the next years of her dissertation. #SciReLab

Happy to share that our #bibliometric analysis of #translational psychological treatment is now published OA in the latest issue of @apajournals.bsky.social's Clinical Psychology: Science and Practice! doi.org/10.1037/cps0... Terminological inconsistency may threaten the progress of the field!

Fantastic new paper by @reeserichardson.bsky.social et al. An enormous amount of work showing the extent of coordinated scientific fraud and involvement of some editors. The number of fraudulent publications grows at a rate far outpacing that of legitimate science. www.pnas.org/doi/10.1073/...

Thrilled to share that The Cambridge Handbook of the Psychology of Violent Extremism is now available. Milan Obaidi's and my goal was to create the book we missed as students—a complete overview over every major perspective in the field.

The book features many prominent scholars such as Alex Schmid, Robin Bergh, John F. Dovidio, Tore Bjørgo, @katrif.bsky.social, Inger Skjelsbæk, Erica Molinario, David Webber, @katarzyna-jasko.bsky.social, Arie Kruglanski, Mirra Noor Milla, Whinda Yustisia, @kbierwiaczonek.bsky.social

Robust Bayesian Multilevel Meta-Analysis: Adjusting for Publication Bias in the Presence of Dependent Effect Sizes: https://osf.io/9tgp2

Fresh of the press! I'm incredibly proud of this new paper by Kiki Vu and myself where we show how much bias is introduced when people use workarounds to test interaction hypotheses meta-analytically. Check it out: advances.in/psychology/1...

@crsugimoto.bsky.social observes that with current Trump cuts to science (about 50%), China will take over as the top science spender in the world this year (without the cuts this would happen by 2030 or so).

New preprint! We meta-analyzed data from 1,114 studies to identify the strongest correlates of migrants' adaptation to living abroad. Co-authored by Kiki Vu, George Tong, Mike Cheung, Nora Benningstad, Evita van Duin, Karine Lindholm, Colleen Ward, and @kunstjonas.bsky.social osf.io/preprints/ps...

Related: PhD students who are told that "identifying a gap" is the most important part of research is probably one of the reasons we have a replication crisis.

Our commentary on emotion-conspiracy theory frameworks was just published! While @lpummerer.bsky.social et al.'s AMCT model is excellent, we show mathematically how model complexity exponentially decreases cross-cultural replicability. Thanks @igi.bsky.social for the invitation!

The more simplistic the take you see on here, the more it generalizes, the more it is an act of politics, not science. If the take comes from a scientist, they know they have no evidence for their take, or they would use it.

As I heard someone repeat the trope that frequentist statistics was developed to promote an eugenicist agenda, here is your reminder that Jerzey Neyman, who created the approach most scientists use to test hypotheses, was a better human being than you are. daniellakens.blogspot.com/2021/09/jerz...

New paper in Nature Comp Reviews led by the brilliant @yarakyrychenko.bsky.social & @tiancheng.bsky.social 👉LLMs exhibit group identity biases. Across 77 LLMs, most “we” (ingroup) prompts yielded more positive while “they” (outgroup) returned more negative sentiment www.nature.com/articles/s43...

New preprint alert! osf.io/ftqdc/ We used the data from a meta-analysis of 1,190 studies on migrant adjustment to find out what methodological challenges the field is dealing with. By Kiki Vu, @kunstjonas.bsky.social, George Tong, and myself.

"even if data are quantitative and numerical, the ways in which they are analysed and, to a greater extent, the inferences made from this analysis, will vary depending on who the researcher is." I LOVE this paper, which talks about reflexivity in quant, not qual, research tinyurl.com/3r3s39ty

Really important perspective paper! Acculturation research will benefit from more systematically considering the various comparison processes in which individuals and groups can engage when coming into intercultural contact.
