I made a #Shiny app about post hoc power and effect-size uncertainty. If you accept an observed effect, you also need to accept its uncertainty. The app shows how power wobbles when you consider the CI, not just the estimate. Embrace the #wobble #samplesize open.substack.com/pub/mzlotean...

Power is wobbly, and 80% might be more like 5%
A Shiny app for showing that power analysis based on an empirical effect-size estimate is only as stable as the estimate itself.

Currently a lot of attention is going to get people to preregister, to check preregistrations, and noting deviations. But the most important step will be evaluating the impact of the deviations! There is almost no work on this. Good topic for a young metascientist!

Insights from the #PSE8 conference Day 2: I was particularly struck by a presentation from Prof Leif Nelson on the detection of problematic data. I wonder how many of us have came across problematic papers - or datasets and don’t what to do!? #ResearchIntegrity #OpenScience

I think it depends on the journal. I’m an editor for @iiirg-iirp.bsky.social & we don’t currently have a IF. We are diamond access & not part of any of the big publishers. This means our community acts as reviews, editors and editorial board members. I see no reason why we would reject replications.

Dr Cody Porter @drcodyporter.bsky.social · 11/02/2026
What if journals adopted a different model? Imagine if, alongside accepting an original research article, a journal also committed in principle to considering well-designed replications of that work. Such an approach could strengthen reliability, and incentivise transparency.

Insights from the Perspectives on Scientific Error (#PSE8) conference 🧵 Day 1: what a thought provoking morning. Replication remains one of the cornerstones of scientific progress, yet replication studies are still notoriously difficult to publish. Many never make it into print at all.
