New blog post from Data Colada, responding to the recent criticisms on p-curve analysis. It is a *very* good response. As in, it addresses exactly the points I would have expected in a reply, and it explains why I will still teach p-curve analysis. datacolada.org/129

This funny post is making the rounds today, and while not intended (AFAIK) to be about git, I think the sentiments are very applicable to explaining the dearth of adoption amongst academics: anniemueller.com/posts/how-i-...

as a big fun of multiverse, I am really happy to see a nice tutorial was just out: psycnet.apa.org/record/2026-... Congrats to @epronizius.bsky.social, @slewis5920.bsky.social @aggieerin.bsky.social & @psysciacc.bsky.social (sorry i did not follow all of the authors here) #Metascience #OpenScience

Thrilled to share: our Special Issue in Social Science Computer Review (@sscratsage.bsky.social) on digital behavioral data quality is out now. Many thanks to all contributing authers and my co-editors @clauwa.bsky.social and Bernd Weiß: journals.sagepub.com/doi/10.1177/...

Rethinking measurement invariance causally by @dingdingpeng.the100.ci It is preferable to work with a causal definition of measurement invariance. A violation of measurement invariance is a potentially substantively interesting observation. Group differences can be thought of as descriptive results

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

A report analysing data from major cross-national #surveys on the #digital divide in Europe has been published today. The #data summary – produced for the Infra4NextGen project (@horizoneu.bsky.social 🇪🇺) – focuses on attitudes amongst younger people compared to older respondents.

Umfragen sind ein tolles Instrument. Das können wir auch. Die Tagespresse beauftragte ein Umfrageinstitut mit der Beantwortung einer drängenden Frage: Wer ist im Freibad unbeliebter – ein Ausländer, oder nicht vielleicht doch ein FPÖ-Chef? dietagespresse.com/wollen-sie-i...

Not immediately related but when you say metrics shenanigans I’m obliged to share this great paper by my close colleagues www.sciencedirect.com/science/arti...

How brilliant is this www.weregildcalculator.com

I’m delighted to share that the August 2025 special issue of Sociological Methods & Research on Generative AI is out now. Along with my co-editor, Daniel Karell, we put together this issue to build on the conference we organized last year. Here's a thread on each of the ten papers:

If researchers find Cohen’s d = 8, no they didn’t. (probably.) Thoughts on the distribution of Cohen's d values in psychology and why we should think about their plausibility when reading articles.

New #rstats blog up! solomonkurz.netlify.app/blog/2025-07... This is the first in a new series discussing causal inference with experimental data using multilevel models. My basic case is g-computation is the way to go.

Big fan of this paper: open.lnu.se/index.php/me...

Es ist schwer, sich des Eindrucks zu entziehen, dass Friedrich Merz Bundeskanzler werden wollte, um auf der internationalen Bühne das Gefühl von Macht und sAnsehen zu genießen. Wie es den Menschen in Deutschland ergeht - affordability, Gesundheitskosten, Klima etc. - scheint unterste Priorität.

On this July 4, liberate the field from cross-sectional “mediation analysis” - check out this new paper discussing an alternative. I bet it’s an instant classic. My sense is that folks continue bad practices bc they don’t know what else to do. This solves that psycnet.apa.org/record/2026-...

This recent working paper by Jim Wyckoff shows that student achievement declines began well before the pandemic, and lays out the evidence for several possible causes. edworkingpapers.com/ai25-1197

I will do an extra 'Open Online R Stream' (www.wvbauer.com/doku.php/liv...) next week Thursday (2025-05-29) at the usual time (6pm CEST). I will talk about syntax style guides, syntax formatting, and take a look at the styler and lintr packages and the new Air formatter software from Posit.

I will teach my advanced #MetaAnalysis course this year (September 24-26, 2025): www.wvbauer.com/doku.php/cou... Since my regular meta-analysis course is also overdue, I decided to extend the advanced course by an extra day to cover the standard methods more thoroughly.
