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.

Not exactly 'low quality,' but a brilliant example of how correlational findings can start to take on a life of their own. The paper title is "Socioeconomic position and the risk of brain tumour" but see the Mirror's headline. Original paper: jech.bmj.com/content/70/1...

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?

The package supports R/quarto files with small hiccups. The next package release will hopefully fully support quarto.

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...

@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!

Yes, yes, yes. And particularly thank you for quoting the essential “Writing is thinking. To write well is to think clearly. That’s why it’s so hard.”

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.
