Typically, the concept of Incommensurability is used within the Philosophy of Science.
Realist and anti-realist philosophies of scienceCommensurability is a concept in the philosophy of science whereby scientific theories are said to be "commensurable" if scientists can discuss the theories using a shared nomenclature that allows direct comparison of them to determine which one is more valid or useful.
On the other hand, theories are incommensurable if they are embedded in starkly contrasting conceptual frameworks whose languages do not overlap sufficiently to permit scientists to directly compare the theories or to cite empirical evidence favoring one theory over the other.

PH et. al. rely upon a realist [philosophical] which assumes mind-independence of reality and thing [noumenon],Eric Oberheim and Paul Hoyningen-Huene argue that realist and anti-realist philosophies of science are also incommensurable, thus scientific theories themselves may be meta-incommensurable.
while in my case of ANTI-realism, I reject the above assumption and rely purely on empirical evidences and its rational inferences within and NEVER beyond experience.
Since realism and anti-realism are incommensurable, PH et. al. with their dogmatic stance simply do not understand [not necessary agree with] the anti-realism perspective.
The concept of Incommensurability was made popular by Thomas Kuhn and Paul Feyerabend.
For Feyerabend, Incommensurability within different Framework and Systems of Science emerged from the following;
- 1.. The interpretation of observations is implicitly influenced by theoretical assumptions. It is therefore impossible to describe or evaluate observations independently of theory.
2.. Paradigms often have different assumptions about which intellectual and operational scientific methods result in valid scientific knowledge.
3.. Paradigms can be based on different assumptions regarding the structure of their domain, which makes it impossible to compare them in a meaningful way.
Thus, scientists are using different terms within their specific paradigm when talking about different theories.
Incommensurability [originally from Mathematics] is not restricted to Science but extend to all fields of knowledge on an inter- and intra- basis, e.g. in the current contention within Morality & Ethics.

Yes, the concept of "incommensurability" can be applied to non-scientific fields as well. Incommensurability generally refers to the idea that some things cannot be meaningfully compared or measured using a common standard.
If science can be objective [intersubjectively] within its specific paradigm [FSK], so Morality can also be objective [intersubjectively] within its specific paradigm.
Why PH et. al. cannot understand my stance of Morality and Ethics is due to Incommensurability arising from the different paradigms we rely upon.
The problem is PH et. al. [dogmatic with realism - semantic] do not seem the understand the effect of "Incommensurability" will have on his assertions and conclusions.
The point is PH et. al.'s FSR-FSK basis of ethics relied upon realism which I had proven is grounded on an illusion.

My point is PH et. al. should be aware [don't think they do at present] and take into consideration the concept of Incommensurability when discussing Morality.
