It's been my experience that people tend to forget that scientists are 'human' too, or more precisely, scientists can be just as willfully blind, self-serving, conformist, fearful and mendacious as anyone else. Some of them are even unabashed con men who falsify their data, or intellectual prostitutes who will produce the results they are paid to, whether they believe them or not. Just because it's been peer-reviewed, or written by a person with a string of letters after their name, doesn't mean it's true, or even remotely so. And if history tells us anything, it's that the history of science is a long history of wrong or incomplete ideas that are continually changed to get closer to the factual truth. So it's best to be skeptical whenever scientists speak in terms of absolutes with certainty, whenever they put the lid on testing alternate hypotheses. Chances are, they're simply deceiving themselves, and you.
Science is a work in progress. The theories that are taken for granted as being true may very well turn out to be completely bogus and those theories we may take as bogus may turn out to be true! Only after following the intervention of new discoveries and innovations can we ever get to the absolute truth!
Of coarse this is only My opinion, no way to prove I am right or I am wrong, only that I AM!
