Cohen’s d is one of the most widely used ways to communicate mean differences across studies. But what, exactly, is it telling us? A perspective on detectability of effects -- just out in PARE: openpublishing.library.umass.edu/pare/article... #openaccess

Up to age 60, adult brain volume completely dominated by stable individual diffs. At 80 yrs, up to 50% reflects differences in change. Interpretation: 1) We change similarly up to 60. 2) Group comparisons often not reflecting changes. @Edvardosg @LCBC_UiO direct.mit.edu/imag/article...

Stable Individual Differences Dominate Adult Brain Volume Variation Until Later Life

Abstract. Individual differences in the volumes of brain structures are often linked to various conditions, including Alzheimer’s disease, schizophrenia, and overall brain health. However, it remains ...

Just gave my last talk of the year! 2025 was quite packed, I gave talks about: - the age-period-cohort problem - making rigorous causal inference more mainstream - mediation analysis - marginaleffects - causal graphs (x10) If you're curious, check out my slides here: juliarohrer.com/resources/

Anke Schneider and I put together a short brochure on sample size planning, aimed at Bachelor psychology students. Our goal: help students justify their sample size plan (other than just relying on defaults) and help avoid common pitfalls. 🚀 For now, it’s only available in German. osf.io/n46vg/

New preprint: Stop thinking of Cohen's d as an effect size. Cohen's d confounds magnitude of effect and reliability. Yet, we pretend our measurements are flawless when interpreting it. What if we thought of Cohen’s d as a measure of detectability instead? osf.io/preprints/ps...

Reevaluating the role of education on cognitive decline and brain aging in longitudinal cohorts across 33 Western countries - Nature Medicine

In a large cross-national study, education was linked to better memory and larger brain volumes but not to slower cognitive or brain decline with age, suggesting that the association reflects early-li...

@anoukbouma.bsky.social makes wonderful remarks on how scientific software often misses users' need. Where is the: "Design, test, and iterate" cycle in scientific software?

I wrote a blogpost on something I’ve been thinking about a lot lately: how metascientists could (and should) think more about their users when designing tools and reforms. Would love to hear any thoughts on this topic! #metascience #usercentered

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes. This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

AI, peer review and the human activity of science

When researchers cede their scientific judgement to machines, we lose something important.

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

Julia M. Rohrer@dingdingpeng.the100.ci · last yr.

Does anybody have a good visualization to explain how interactions can be confounded, and why interactions require interaction controls? @urisohn.bsky.social maybe? (Asking because I have an idea, but want to check out what exists already before investing the effort)
