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.

FAIRness differed mainly by repository, with GitHub and OSF showing lower median scores than PsychArchives, Zenodo, and Figshare

How FAIR is shared data in psychology?

We analyzed 11,384 datasets (2013–2024): They're findable, but less reusable!

What relates most to differences in FAIRness? #Repository choice.

New publication!

Matthew Horsey, Kana Imuta and I integrate insights from social, cognitive, political, and developmental psychology and propose a lifespan model of conspiracy belief formation, from infancy, through childhood and adolescence, into adulthood.

GitHub - profandyfield/discovr: discovr package for R to accompany Discovering Statistics Using R and RStudio discovr package for R to accompany Discovering Statistics Using R and RStudio - profandyfield/discovr

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.

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

An Examination of the Relationship Between Conspiracy Beliefs and Dispositional Individual Victimhood Conspiracy beliefs have been linked to perceptions of collective victimhood.

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...

It's ok to acknowledge one's positionally in the world while doing research. There's no way to avoid the reality that where you stand is based on where you sit.

@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).

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...
