Smartest Guy in the Room Syndrome

[Reverend What's-His-Name?]

I think there is a corollary to this as well which is the person who is unwittingly perceived as the Smartest Guy or one of the Smartest Guys in the room.  And it usually is someone who is certainly a very capable person in any given field or area of expertise, but not someone who holds themselves as the Ultimate Guru of Everything.  And then that person gets laden with everyone else's work.

What was this toolery?  Geezus
