The 3/5 profile (Martyr / Heretic) 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 3/5 profile joins the roles named Martyr / Heretic. 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 third line, Martyr or Adaptor, as learning through direct trial and error, discovering by getting things wrong what actually works; the fifth line, Heretic or Universal, is described as a practical, crisis solving line whose fixes get projected onto by people it has not met, cast either as saviour or as scapegoat. The 3/5 profile combines the two: within the system's own teaching, the errors and adaptations the third line makes in private become, through the fifth line, material other people draw on and judge in public, so that a personal process of trial and error is read, often against the person's own wishes, as a public demonstration.
