On the outlook for fit quality It pays to be on the outlook for quality, even in the realm of opinions. Good opinions may be even better articulated. Then they can be made use of as working hypotheses in the realm of science. Further note there is more than this one way to guard quality opinions and presentations. Much depends on how skilful someone is too.
Some people think that the opinions of many count because they are much shared.
Such persons may be likened to sheep. Where all think the same, no one thinks deeply and well. History shows that may be wrong - all of it. The earth is not flat as a pancake - even though that was the creed for centuries and more. The creed didn't make it flat either.
