Heretic / Investigator

The 5/1 profile (Heretic / Investigator) 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 5/1 profile joins the roles named Heretic / Investigator. 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 fifth line, Heretic or Universal, as a practical, crisis solving line that draws projection from strangers, cast as saviour or scapegoat depending on outcome; the first line, Investigator, is described as needing a solid personal foundation built through study before it feels safe to act. The 5/1 profile combines the two: within the system's own framework, the practical solutions the fifth line offers under others' projection are understood to rest on a private, researched foundation the first line supplies underneath, which practitioners commonly describe as giving this profile's public problem solving an unusually well grounded, if still exposed, footing.

This profile pairs the fifth and first line positions of a hexagram, separated by two positions counting round the six, and it is one of the twelve ordered pairs Human Design admits.

The positions in classical commentary

The fifth line is the central line of the upper trigram and conventionally the ruling position of a hexagram, the best placed of the six in the commentarial tradition. The first line is the bottom of the figure, the beginning of the situation, read as obscure and not yet able to act.

Those are readings of positions within a described situation. The Yijing tradition does not use them to classify people.

Why twelve and not thirty

There are thirty ordered pairs of distinct lines. Human Design uses twelve: the six ordered pairs whose lines are separated by three positions, and the six separated by two. The separations of three coincide exactly with the Yijing's doctrine of correspondence between lines one and four, two and five, three and six, which is a genuine structural inheritance. The separations of two, of which this is one, have no counterpart in that doctrine.

The modern layer

The role names attached to the six lines, and the reading of a pair as a personality, are Ra Uru Hu's, published in 1987. The atlas records the inherited structure and the modern interpretation separately.
