[Retric]

While this sounds bad it's probably a sign of the amount of scrutiny Nature articles are under not the Quality of what's published. Basically, the rate of detection is higher in Nature so even if the underlying problem is the same or even less it’s going to look worse.

Indeed. I don't think anyone is saying that the high retractation rate implies that Nature paper are worse than other papers. However it is a sign that they may not be that much better either.

I would expect that the resulting quality of not-retracted and proven-by-time papers in Nature is a lot higher than in any other journal. Simply because of higher exposure, more attempts to reproduce or use studies and more scrutiny.

But... isn't that really the same thing? Not worse but not much better. Sounds like about the same.
