Anybody who thinks they don't have preexisting biases and can do totally unbiased scientific inquiry is severely deluded. We see what we want to see all the time.
Hogwash , peer review is not a mass hallucination shared by independent researchers. It is however a consensus of minds in a concerted effort to find the truth. What ever bias is held is destroyed by the many eyes that must see the same exact thing.
If there is conflict there is no consensus, if there is consensus
there is no conflict. Except by unvalidated accusation , exactly like yours which has zero merit.
