To be more precise (although I haven't spent much on the paper): heterogeneity and confounding aren't the same. Moderators help with the former. However they also change your Estimand. I don't like that as a solution.

If you are an experimental researcher and can randomize the this is unnecessary. Most often the Obs study ppl and the experimental ppl don't talk to each other.

100% this, especially with Wiley given their anti-preprint stance.

Francesco Poli @francescopoli.bsky.social · 14d

Why are we still sending our work to Wiley and other publishing companies so that they can profit from it? There's so many better options now, for example: psychopen.eu/journals/

agreed. it is often very annoying when you see that either someone names something very poorly, or that the "better" name is already used by like 3 other things (e.g., e-values vs E-values).

#stats Q: In frequentist, we use Confidence Intervals (CI). In bayesian, we use Credible Intervals (CrI or CI also). Given this overlap in initials, should we collectively move to Probability Intervals (PI)? Or does this confuse things with Prediction Intervals? Thoughts?

It's the measurement error that gets in the way. You can have thousands of people do a specific task, but if that task isn't all that good then you have very precise rubbish.
