It needs a serious dose of Thomas Kuhn's The Structure of Scientific Revolutions. Science goes through huge upturns and there are intense debates, followed by periods of slow and steady progress, then another upheaval. This is normal and good. We stand on the shoulders of giants, while looking down at all of the wacky things they also believed (Newton believed in alchemy, astrology was all the rage for way too long, all the greats had some messed up beliefs about race).
The whole point of science is that you keep doing science and you keep updating your beliefs based on the results of the method, not that you believe eternally in the findings that come out of a single article in a scientific journal.
