Wasn't this study immediately debunked due to bad statistical methods? See https://zenodo.org/records/18002186
> Using simple simulations,we show that this pattern arises naturally from collider bias when selection into elitesamples depends on both early and adult performance. Consequently, associationsestimated within elite samples are descriptively accurate for the selected population,but causally misleading, and should not be used to infer developmental mechanisms

Is that paper in print? I can't seem to find if it was peer reviewed.
If the paper is true, then, yeesh! That's a pretty big miss on the part of Güllich et al.
Reading through the very short paper there, it seems to not have gone through review yet (typos, mispellings, etc). Also, it's not clear that the data in the tables or the figure are from Güllich's work or are simulations meant to illustrate their idea (" True and estimated covariate effects in the presence of simulated collider bias in the full and selected samples"). Being more clear where the data is coming from may help the argument, but I likely just missed some sentence or something.
I'll be interested to see where this goes. That Güllich managed to get the paper into Science in the first place lends credence to them having gone through something as simple as Berkson's Paradox and have accounted for that. It's not everyday you get something as 'soft' as that paper into Science, after all. If not, then wow! standards for review really have slipped!
