“Follow science” and ‘follow “the” science’ are two different things, and we just need to go back in history to understand that humans did some horrible stuff because of “the” science.
Your intuition of scientists updating views is wrong, see Kuhns scientific revolutions for more examples. Scientists generally stick to preconceived notions long after there is data to refute them.
E.g. heliocentrism, germ theory, cigarettes being unhealthy, lobotomies being optimal
What we call ‘truth’ is just the beliefs we think are most accurate. ‘Just follow the science’ is silly because it essentially means following beliefs on faith without questioning whether they are the best theory. In many cases the better theory goes against the consensus.
E.g. mothers who ‘just followed the science’ and took Thalidomide caused their children untold suffering. They could have been skeptical but instead they had faith in science, which was unfortunately done badly.
