The 4/6 profile (Opportunist / Role Model) is one of the twelve profiles of Human Design, a modern esoteric system originated in 1987 by Ra Uru Hu and presented here as a contemporary framework rather than ancient wisdom. A profile is formed from two of the six lines, a scheme the system borrows from the six lines of an I Ching hexagram and reads psychologically: the profile pairs a conscious line with an unconscious one to give an archetypal role. The 4/6 profile joins the roles named Opportunist / Role Model. The line names and their meanings are Human Design's own twentieth-century reading, not a claim inherited from the Chinese classic whose six-line figures suggested the structure; they are described here as the system presents them, not as verified fact.
Human Design describes the fourth line, Opportunist or Networker, as needing an external foundation built from a fixed circle of friends, through which opportunity arrives; the sixth line, Role Model, is described as living a three part life, active and trial and error in roughly its first thirty years, withdrawn into a more detached, observational phase often called being on the roof through about fifty, and only afterward settling into the line's objective, lived wisdom. The 4/6 profile combines a personality built on fixed friendships with an unconscious pattern that, in the system's own account, only fully steps into role model authority once the sixth line's observational middle period has passed.
