It's treated more as a set of religious rituals justified by received wisdom (which, to be fair, gives even less flexibility for change than if it were viewed as a science, in which case practices would be based on systematically gathered evidence and change in response to new evidence, rather than changing mostly when people indoctrinated in a different tradition come to power in an organization.)

Actually yes, that does seem to be a more appropriate analogy. A lot of the time people follow a system without testing whether or not it's working.
