I understanding it completely. If something can pass peer review and be published before retesting and re-experimenting, how much stock can be put into a peer reviewed and published articles.
First, that is dependent on the reputation of the journal and the subject matter.
Second, If it is in my specialty Geology, geomorphology, and environmental sciences I always rely on multiple sources and do not take any one research article alone at face value. I do not believe any competent scientists would take any one research article at face value without referencing multiple sources.
I've all ready posted the graph as to what peer review consists of.
OK graph, so what?!?!? It is superficial and does not address the issue how peer review is integrated in science methods.
Peer review does not stand alone as the standard for judging the value, validity, repeatability, nor reproducibility of the research.
