The Jargon File (version 4.4.7, 29 Dec 2003):

Stupids
 n.

    Term used by samurai for the suits who employ them; succinctly
    expresses an attitude at least as common, though usually better disguised,
    among other subcultures of hackers. There may be intended reference here to
    an SF story originally published in 1952 but much anthologized since, Mark
    Clifton's Star, Bright. In it, a super-genius child classifies humans into
    a very few ?Brights? like herself, a huge majority of ?Stupids?, and a
    minority of ?Tweens?, the merely ordinary geniuses.
