@MarcusMunafo 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!

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...

While individualism and isolated work remain common in #academia, coordination offers substantial benefits. This Comment urges systemic changes from all stakeholders toward more coordinated #science. @sajedeh_rasti @lakens nature.com/articles/s4156…

@lu_sichu @tracewoodgrains 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…

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…

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.

Sometimes you need a carrot, sometimes you need a (small) stick. @JSportsSci 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…

20/ Final word: Let scientists decide what counts as evidence. Let society decide what to do with it. Don’t confuse acceptance with action. Neyman’s behaviorism in science is about inquiry, not policy.
Constantin Späth @cspaeth.bsky.social retweeted
12/ Scientists are responsible for error control—not for managing risks in the world. Those risks must be evaluated by policymakers who apply the science, not by those who produce it.
