This is a fun study, and I agree the CLPM totally sucks. Still... the question of how severe a test it is relates to how it behaves when testing a *false* hypothesis. So the fact we don't know how many of those 98*2 causal effects exist in reality seems a little troublesome...
So please send us your work!

A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸
How about we reconsider the idea that sciencey science involves collecting own data.

AI-generated ‘participants’ can lead social science experiments astray, study finds
Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

Have you considered getting them to use SPSS via a remote desktop connected to a university machine? Because I find that's always fun too
No. Post-publication peer review is an essential and under-appreciated service to the scientific community, and not remotely criminal. I'm sure it's upsetting to have problems in your work identified, but the solution is to do better science.

Some researchers don't discuss their future research plans for fear of being scooped.

BEWARE: Surveys that allow anyone to "opt in" are vulnerable to those who create many accounts (using VPN to bypass IP limits) & use automated tools to generate bogus responses (such as saying "yes" to question about being licensed to operate nuclear submarines).

In my experience PCI RR reviews are also pretty darn comprehensive and thorough! I guess YMMV though
Reviews from PCI would come from a specific thematic PCI. peercommunityin.org/current-pcis/ For those 3 journals the closest possible match is PCI RR (were they registered reports?), but that feels unlikely - only 1 of the 3 (Collabra) is a PCI RR friendly journal.
Current PCIs - Peer Community In
Here is the list of the different Peer Communities In already created, hosting recommendations and peer-reviews of preprints and ready to receive your submissions

It doesn't sound like a problem. Unless a plan to stop if the estimated effect at peek 1 was under the SESOI was part of the initial plan and incorporated in the alpha spending calculation somehow?

The mods will be gradually chasing authors up to get these updated and accepted, but if you know this is you, updating the preprint to list all the authors will speed things along 🙂

If you have submitted a preprint to PsyArXiv in the last year or so and it *isn't* currently accessible, there's a good chance it's due to the document listing authors whom you haven't entered in the metadata.
You can contact [email protected] to discuss?

When reporting on these kinds of claims, the media should ask:

What an odd paper!
This bit sounds faintly reasonable at first glance, but do we have any reason to expect that cross-sectional mediation would be much use for identifying candidate mediators to test experimentally? And how can something "account for an association" without having causal effects?

Authors, reviewers, editors... none of them noticed that the title is inconsistent with what the authors themselves acknowledged about the methods?

I think you are referring to the idea of a "backfire effect" when debunking myths. The problem is that the backfire effect is itself essentially a myth.
