their title is far less interesting to me than their actual reasoning.
I'm not sure what titles have to do with this? I didn't cite any titles in my comment.
Titles convey the scope of responsibility and authority that someone has been delegated within an organization; that is the only value I see in titles. (People within an organization typically refer to consultants in lower case because consultants are external to the organization and therefore have no responsibility or authority within the organization.)
I agree reasoning is important, but it's a process, and, like all processes, the quality of its output is heavily impacted by the quality of its input.
If I've been diagnosed with lung cancer, I want the opinion of an oncologist (which is a common noun, not a proper noun), not of a neurologist, no matter how excellent the neurologist's reasoning skills might be. If for some odd reason, the oncologist's title includes the proper noun "Neurologist," he would still be an oncologist, because a title does not an oncologist make. Conversely, if a neurologist's title includes the proper noun "Oncologist," I would still not consult him about lung cancer.
