In response to the OP: I think this would be very context dependent so it’s kind of hard to give an answer

I think what ultimately will matter in this context is that it needs to be consistent for each study. I see the argument with either the resid SD or the raw within group SD, but I would worry about a meta-analyst mixing and matching them in a meta-analysis

"Meta-meta-analyses trade precision & rigor for expediency. If your aim is rigor, there’s no substitute for doing the hard work."

Preach!

I once read a #meta-analysis that mistook SE for SD. Since then I am suspicious of all such studies.

Do the hard work!

This is very nice from @matthewbjane.bsky.social as to why umbrella reviews are basically useless (sorry!), essentially because they compound up the issues with the meta analyses they include. I have the same concerns but articulate them less eloquently. matthewbjane.github.io/blog-posts/b...

No a meta-meta-analysis-analysis

I think my reaction to the first time I saw it was something along the lines of “wait you can just do that?”

I've moaned about meta-analyses of meta-analyses for a while and had several interesting experiences reviewing them... Now I can save time and just send people to Matt's post to explain why not to do them.

Yeah I might do that. Maybe I’ll make it into a pre-print for now

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.

I’ve been hearing it’s good. No spoilers please, still gotta watch it

Most meta-analyses are bad, some are useful

I'm calling for a total and complete shutdown of JAMA Pediatrics until we can figure out what is going on goodscience.substack.com/p/the-resear... I mean, come ON

(#metascience) A good article by @stuartbuck.bsky.social on the Fluoride and IQ meta-analysis: goodscience.substack.com/p/the-resear.... Summarizes some of the points in our forensic review of it (see the forensic review as a pre-print here: osf.io/preprints/os...). Very nice excerpt below:

We tried to. Best we can do for now is submit to meta-psychology and post a pub-peer comment

Nah y’all are right.

The meta-analysis on Fluoride and IQ by Taylor et al (2025) is methodologically flawed and has data integrity issues. The full report by me, @jamesheathers.bsky.social, and @drg.bsky.social is on OSF: osf.io/preprints/os...

Don’t do it

Spent the past couple days looking at meta-analyses in body comp literature to get reasonable parameter estimates to use in simulations for a study we're planning and really trying to avoid giving myself a to-do list of meta-analyses that I need to correct/redo 🙃 cc: @matthewbjane.bsky.social
