My paper on concerns about replicability, theorizing, relevance, generalizability, and methodology across 2 crises is now in press at the International Review of Social Psychology. After revisions it was 17500 words, so it is split in 2 parts: osf.io/dtvs7_v2 and osf.io/g6kja_v1

Only one of these two is what you are paid for by the tax payer, so that should be relatively simple 😏

I went to Rotterdam for a reproducibility therapy session with @lakens.bsky.social. I am happy to report that the patient is doing much better—maybe due to a placebo effect. Who knows.

Doing the right thing, just because it is the right thing is underappreciated by academics.

People sometimes say they do not have time to do open science. But they can use the time they would have needed 40 years ago to send and request paper copies of articles to read the literature.

Somehow we never acknowledge where we gained time that we can invest in open science.

People kept buying incandescent light bulbs, even though LED lights were better for the environment and cheaper in the long run. But incandescent light were cheap in the short term. In the end, the EU had to ban incandescent lights.

The adoption of Open Science works same.

Really nice example if you want to explain why statistical significance does not equal practical significance.
N = 200,000, effect size r = .05. Good enough to support the null-hypothesis with equivalence testing. @lakens.bsky.social

I have updated the blog post with a long reply y Andrew Gelman, in which he clarifies he still recommends the regular use of Type S and M errors. daniellakens.blogspot.com/2025/09/type... This makes our preprint criticising Type S and M errors all the more important.

I am really looking forward to having so many excellent meta-scientists over for the Paul Meehl Graduate School symposium. It looks like this year will be even more fun than last, with interesting talks and lots of opportunity to network.

Extremely honored to recieve Oslo New University College's science award for 2025. ONH has been a fantastic base to conduct my research at for the past 4 years, and I have an amazing team of colleagues around me to thank for that. From the bottom of my heart, thank you all!

Oh, how cool, so they adapted it from this much earlier image! Thanks for letting me know!

You would have a 100% error rate if you did that.
