And science is not supposed to be immune to this, the culture of science is supposed to uncover things like this/errors like this as part of a process. The truth has a habit of shining through if you are encouraged to keep asking questions and follow up on them.
And again, not saying the system is perfect or that calling things out is enough. But too often comments like this get turned anti-science or "we can't improve anything, slow decay is inevitable" cynicism (or FUD if you want to be less charitable)
