Pure Science is not an ideology; it is a method of examining claims through empirical investigation and then drawing a conclusion that has predictive value. It uses the framework of mathematics and statistics to analyze the evidence, thereby opening up further avenues of investigation to test deeper claims. In this regard, it has been very successful.
Having said that, the Philosopher Paul Feyerabend argues that when the practitioners of science become dogmatic and political in their outlook, they transform the practice of science into a milieu dominated by groupthink. The willful neglect of contrary evidence and the elevation of the power dynamic of credentialism then dominate.
This invariably results in stagnant thinking, the formation of a closed secular priesthood/authority, and the sacrifice of the rigorous scientific methodology to preordained conclusions.
