Sometimes you need a carrot, sometimes you need a (small) stick. Journal of Sports Sciences we've introduced a mandatory sample size estimation and justification section to manuscripts. The rationale is outlined in the editorial. Editorial tandfonline.com/doi/full/10.10… IFA tandfonline.com/action/authorS…

Happy Friday everyone! I just posted what I think is an important blog post on my website. It is a critique of meta-meta-analyses: meta-analyses of meta-analyses.

"If the use of a tool is detached from a philosophy of science it risks becoming a heuristic." x.com/lakens/status/…

In short, theories serve human purposes; their creation is motivated and their logic is organized by the skills and limitations of human capabilities. - Robert Dubin

What an interesting talk with Grant Abt, with quite a few references to Daniël Lakens Check the video out - youtube.com/watch?v=oD8Ip_… and the comments for the slides.

I'm pleased to announce the publication of two important papers in Sports Medicine on the first every large replication project in sport and exercise science. Read the full papers: link.springer.com/article/10.100… link.springer.com/article/10.100…

Very excited to publicly share news about a new tool, Papercheck, that Lisa DeBruine and me started to develop more than a year ago! In an introductory blog post, we explain our philosophy to automatically check scientific papers for best practices. daniellakens.blogspot.com/2025/06/introd…

Academic influencers hyping results because p < .05 😃 Actual academics:

Sichu Lu([email protected]) TracingWoodgrains Mixed feelings. In practice he is right. The big problems are as follows: - people who conduct meta-analyses are often not meta-analysts so they haven’t a clue what they are doing or how to interpret anything. - I think there is a fundamental misalignment between what readers

I just became president of a scientific society and my first act was to disagree with one of my heroes...Arie Kruglanski gave a keynote arguing social psychology needs MORE Big Beautiful Theories. I think that's exactly backwards. Here's why...

Marcus Munafò Thanks for trying! It is still amazing how slow the uptake of equivalence testing is, given that it is just a 90%CI of the same test you ordinarily do, but against a smallest effect if interest. Yes, setting it is a challenge, but important enough to spend some time on!

Too often, I see people talk about a replication as if the first study has established something, and the replication study is a double-check. What people often fail to understand is that we do not do replication studies to *check* a finding, but to *establish* a finding. 1/x

Not having to deviate from your preregistration is how you impress peers. You demonstrate you know something, because knowledge allows you to make good predictions. The more deviations, the less impressive the tests in a study are.
