I (see upthread), a scientist myself, think it's absolute hogwash, and i'm certainly not abnormal among my peers in that.
There's something about being the person who not only watches how the sausage is made but has spent (ack) 14 years at this point making sausages of several kinds that kind of strips away overly idealistic expectations about How Pure And Right This Thing Must Be. If you're lucky, and i think i am, you learn enough humility to acknowledge the value of other people's sausage-makings. And, often, have the right state of mind to see and acknowledge the intellectual power and meaningful contributions of people well outside my field.
It is strange being in a group and seeing my group believe one thing but hearing people claim to be part of my group and telling me that I'm not doing it right. Even when I have the credentials and they don't...
On second reading, I think the author is objecting to the practice of denigrating respectable modes of inquiry as "pseudo-science" merely because they cannot match some idealistic standard of rigor.
Whereas under pseudo-science I considered Eugenics, a belief system finding that mankind would go extinct due to inferior breeding.
1. Using the words “science,” “scientific,” “scientifically,” “scientist,” etc., honorifically, as generic terms of epistemic praise.
2. Adopting the manners, the trappings, the technical terminology, etc., of the sciences, irrespective of their real usefulness.
3. A preoccupation with demarcation, i.e., with drawing a sharp line between genuine science, the real thing, and “pseudo-scientific” imposters.
4. A corresponding preoccupation with identifying the “scientific method,” presumed to explain how the sciences have been so successful.
5. Looking to the sciences for answers to questions beyond their scope.
6. Denying or denigrating the legitimacy or the worth of other kinds of inquiry besides the scientific, or the value of human activities other than inquiry, such as poetry or art.
