: In addition to circularity, I would also add a fallacy of relevance in your appeal to authority or popularity. Not that this isn't to be expected, it is however, in my opinion, flawed. Surely, a discussion of the merit of each would be a better criterion upon which to stand.
In the case of deciding whether a something is true or false, appeal to authority and popularity is a fallacy. When it comes to standardisation/convention on what to call things, what else is there to appeal to?
