Note that this tag also exists:
Suggestion: Change name to "Expertise and Authority" (There's no Authority tag currently)
I think 'authority' is more closely linked to https://www.lesswrong.com/tag/social-status (which should probably stay a separate page).
Some ways of broadening/clarifying the scope that seem clearer to me (though I'm not sure any of these are better than just 'Expertise'):
None seem better than just expertise. if this page wasn't changed to "Expertise and Authority", do you think "Authority" should have its own page?
Anyway, I'll link social status as a related page
