Investigator / Martyr

The 1/3 profile (Investigator / Martyr) 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 1/3 profile joins the roles named Investigator / Martyr. 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's own teaching gives each of the six lines a role: the first line, Investigator, is described as needing a solid personal foundation, built through study or research, before it feels safe to act; the third line, Martyr or Adaptor, is described as learning instead through direct trial and error, bonding with others through shared experience rather than shared ideas. The 1/3 profile combines a conscious need to investigate before moving with an unconscious pattern of learning by getting it wrong first, which practitioners of the system commonly describe as an investigative, somewhat solitary way of testing the world that circles back to research after each attempt, rather than a profile that settles into either mode alone.

A Human Design profile pairs two of six line positions, a structure taken from the six lines of an I Ching hexagram. The Chinese commentarial tradition has a great deal to say about those positions, and it is not what Human Design says.

What the commentaries say about these two

In the classical Yijing commentaries, the first line is the bottom of the figure, the beginning of a situation, and is generally read as obscure, undeveloped and not yet in a position to act. The third line is the top of the lower trigram, a transitional place, and the commentaries repeatedly describe it as a position of difficulty or danger, caught between the lower situation and the upper.

Those readings are traditional, they are attached to positions within the hexagram, and they are about the situation the hexagram describes rather than about a person.

What Human Design does with them

Human Design assigns each of the six lines a role name and reads a person's profile from a pair of them. The role names and their meanings are the system's own, published by Ra Uru Hu in 1987. They are not translations of the commentarial positions and should not be read as a claim about Chinese tradition.

The pairing rule

Of the thirty ordered pairs of distinct lines, Human Design uses twelve: exactly those whose lines are two or three positions apart. That constraint is structural and is described in the articles on the other profiles.
