With all due respect, I feel like this subject is somewhat superfluous. It seems to be trying to chop part of a general concept off into its own discrete category.
This can all be simplified into accepting that Expert and Common majority opinion are both types of a posteriori evidence that can support an argument, but can be overturned by better a posteriori or a priori evidence.
In other words, they are pretty good heuristics, but like any heuristics, can fail. Making anything more out of it seems to just be artificial, and only necessary if the basic concept proves to difficult to understand.
