Reading cavalier statements by the likes of N. D. Tyson, Richard Dawkins and Stephen Hawking, promoted by their PR teams as the prophesies of objective truth, makes my blood boil. Well, in the first instance. Then I come to my senses and remember that there is definitely a practical need in unquestioning foot soldiers in science, people who will do their allocated job without asking big questions, and just keep refining and confirming the established bias until it's time to move on to the new paradigm. In sciences too, it takes every kind.
On that note, however, I am positively convinced, that scientists should by no means be awarded a PhD, Doctor Philosophiae, degree, unless they complete a foundation course in, at least, epistemology and prove beyond any doubt that they understand how the process of knowledge manufacturing works. If they refuse, they should graduate with a Doctor in (Specific Field) accolades.
