How do we reliably identify the decline effect and bring its implications to bear on existing Q&A on this site?
I would think maybe the answer is almost too obvious: write an updated answer. But then again, maybe there's more to it: how to raise awareness where applicable?
This question was prompted from reading the answer in this post: May I cite a single article? It says more weight should be given to "multiple papers" and "reproductions of experiments". This is correct because in traditional science this is necessary. However, the problem is that some studies/papers/researchers have possibly not adhered to the scientific method strictly enough, or that new evidence or results have come along (thus pushing an "established" study back into the more appropriate category of "exploratory experiments" or mere "preliminary findings").
