No, it isn't good. It is brittle and dogmatic, and these dogmas are often thinly-evidenced ("now we know stress is all about cortisol levels!"). It means vast categories of human knowledge are regularly discarded without understanding or examination because of epistemological prejudice. And the process is not by any means lacking in false positives; this presumes that our current modes of knowledge are actually better, less error-prone, etc., than the forms of knowledge they are refusing to countenance, which they often are not.
