If you would do a deeper study of the history of science, you would find multitudes of scientists who got it wrong over the millennia. Just because we live in modern times doesn’t mean that stopped happening.
There was a conversation upthread about dietary recommendations that read like a recipe for diabetes and obesity now.
Another example from the 19th century: read about Semmelweis. The first doctor to discover that clean hands are a good thing. As I bang on about washing one’s hands, I could consider him my patron saint. He was so unaccepted by his peers, he died in an insane asylum. It took the efforts of Pasteur and Lister years later to support Semmelweis’ work.
Complex science is never “settled”; it is always in a state of flux as our knowledge advances, often in fits and starts. Sometimes the new knowledge adds to what we have, sometimes the new knowledge forces us into a turn. Sometimes the new knowledge acts at cross purposes to the narrative of the day. One sometimes has to set the accepted narrative in the background so that one’s mind can be open to observing what is actually there in lieu of accepting what we’re told is there.
