Did organized Objectivist activism, at least in some of its nuttier phases, offer to turn its adherents who get it right into a kind of superhuman entity? I guess you could call such enhanced people "Operating Objectivists," analogous to the enhanced state promised by another cult.

Not that I'm aware of, but you might also be interested in A. E. Van Vogt's "Null-A" novels, which attempted to do this for a fictionalized version of Korzybski's General Semantics.

(Van Vogt later did become involved in Scientology, as did his (and Hubbard's) editor John W. Campbell.)
