just to revisit this a bit....
bold: I agree
underlined: this seems to be the fundamental problem with your reasoning. Method for what? For science? well... yes.
Science itself is clearly demarcated because it isn't terribly complex. It is just the ideal. How about methods for attaining scientific validity? I would agree (and mentioned so several times in ways that didn't use a thesaurus but still seemed too complex for you) that there is plenty of wiggle room here. What some people consider to be "good science" others would not.
However, your initial post and those which follow (and this is treating it as if there isn't a bored and/or sexually frustrated troll off his meds sitting across from me on the internetz right now) pose the question, "is science capable of uncovering truth". Without waxing overly philosophic here.... the answer is yes. Any shortcomings are not the fault of "science" but of those who attempt to wield it. You allude to this in the OP when you talk about the career opportunists. So basically, I am still unsure why you are so hung up on this.
to recap some of the confusions around here --
"Science" is a concept. The things you are complaining about are not science, they are scientif
ic (or scientif-ish if we are talking about things like homeopathy

) i.e. of or relating to science... I think... I dunno, you're the arbitrary scholar here, am I using my suffixes correctly?
😀
Yes, "scientif
ic validity" is determined by popular vote. We recognize that a purely unbiased and systematic approach is often unreasonable or impossible. But anything attempting to reach an ideal suffers from the same pitfall and is inescapably subject to assessment through popular opinion (btw, this would be a fun place to plug your earlier reference to religion/cults/whatever). However, this has little to no bearing on whether or not the ideal that was attempted to be reached is still valid.
