Understanding the 1/3 Investigator Martyr Human Design Profile

Learn about the Human Design1/3 profile, how it works with your aura type to influence the way you experience life, and how it impacts your relationships.

Overview of the Investigator Martyr 1/3 Profile in Human Design

Developed by Ra Uru Hu, the Human Design system is said to provide a blueprint for how we should each live our lives, with each aura type here to fulfil specific roles. We can read this information on a Human Design chart, or body graph.

The body graph is made up of various components, each providing different elements of information about an individual’s unique design, including their aura, profile, definition, and authority type. Together, these make up the basics of Human Design.

The profile lines offer insight to your personality, with each one bringing its own specific set of qualities and innate gifts, teaching you more about your life purpose and incarnation cross.

Quick recap about the profile lines…

The 12 profiles are each made up of two of the six profile lines, which correspond to the six lines of the hexagram. They comprise of:

  • 1st Line – The first line is the line of the Investigator
  • 2nd Line – The second line is the line of the Hermit
  • 3rd Line – The third line is the line of the Martyr
  • 4th Line – The fourth line is the line of the Opportunist
  • 5th Line – The fifth line is the line of the Heretic
  • 6th Line – The sixth line is the line of the Role Model

Every human being has their own profile number which can be found by looking at the unique design of your body graph. 

Your conscious profile calculation is derived from the position of your personality sun / earth (conscious personality), and your design calculation is based on the position of your unconscious sun / earth.

When we talk about profiles, the following three important things should be borne in mind:

  1. When looking at your profile lines, the first one is tied to consciousness, and the second to unconsciousness.
  2. They provide potentials for your life, not guarantees.
  3. They ultimately manifest in a different way depending on your Human Design type, and they should therefore be read in conjunction, as a unique way to navigate the world.

The 1/3 has two fundamental qualities from which they thrive: research and discovery.

The 1/3 profile is the only one of the 12 profiles with both lines in the lower trigram. This manifests as a deep, burning desire to create a solid foundation from which to experience life.

Stability is key to a comfortable life for the Investigator Martyr.

In addition to this drive for stability, the 1/3 has two fundamental qualities from which they thrive: research and discovery. They also tend to crave introspective time alone to process the information they uncover.

The compulsion to spend time researching stems from the first conscious line in the profile, while the thirst for discovery comes from the unconscious third line.

Let’s take a closer look at how each individual profile line is expressed, and the 1/3 profile in context of energy type.

The 1st Profile Line – Investigator

Researches and scrutinises things closely; needs to have a deep understanding of the world in order to feel secure.

The conscious first line is one that the 1/3 likely recognises in themselves and identifies with strongly. It’s all about building a strong foundation of information from which to operate. 

Anybody with the first line in their profile has an innate need to thoroughly research topics that are important to them in order to get to the bottom of things.

The Investigator Martyr’s desire for rich knowledge is rooted in a need for security.

When it comes to areas of expertise for a 1/3, it’s not only formal learning that drives this need for meticulous investigation. It might be any subject matter which lights them up on a personal level, or it might be in relation to their circumstances.

For example, 1/3’s may be driven to deep dive into the pros and cons of making a big purchase, checking out and comparing a product’s features, and devouring every review they can lay their hands on. Likewise if they’re looking for a good restaurant to visit.

The Investigator Martyr’s desire for rich knowledge is rooted in a need for security. 

Investigators feel confident in sharing information they’ve personally sourced and verified. 

All living things are primarily motivated by their drive to survive, and according to Ra Uru Hu, the essence of the first line meets this need by providing security around decisions and actions: 

Thorough research increases the likelihood of making the right choices.

In addition to providing security, Investigators also feel confident in sharing information they’ve personally sourced and verified. 

Knowing that their fastidious study of a topic has cultivated a deep understanding empowers those with the one line to share what they’ve learned, secure in the knowledge that they are an authority in the subject.

False Self in the 1/3 Investigator Martyr Profile

The not-self theme shows up only in the conscious line, which is manifested through the mind and therefore vulnerable to conditioning. The unconscious line on the other hand, which is manifested through the physical body, cannot be influenced in any way.

For profile 1/3, the not-self theme is the first line of the Investigator.

Often a situation can appear positive on the surface.

The false self manifests in the Investigator as a step away from conducting research, which is correct for this profile, instead getting carried away by circumstances which appear to show promise and acting on that vision of idealism.

Unfortunately for the 1/3, while occasionally this course of action may coincidentally pay off, there will be many more times when it will go awry. 

Often a situation can appear positive on the surface, and it’s only after careful consideration, based upon close inspection and research, that its flaws become apparent. This is key for the 1/3, and in this way the not-self theme can create problems.

The 3rd Profile Line – Martyr

Amiable; likes to discover by testing theories and learning through life experiences, failure, and the process of trial and error.

Line three is all about discovery and learning through personal experience. The third line of the Martyr manifests subconsciously for profile 1/3, meaning individual’s with this profile may be unaware of these traits in themselves.

When living correctly according to strategy and authority, each line balances the other out.

It’s also notable that the characteristics of the 3rd line are contradictory to those of the first line. But while this may suggest the possibility for internal conflict, when living correctly according to strategy and authority, each line balances the other out.

Line one by itself could lead to uncompromising rigidity in life, while line three by itself could result in a lack of responsibility and stability in life.

The combination of both qualities produces a person who is keen to explore new options and experiences, but with a sensible head on their shoulders which prevents them from taking excessive risks.

Aura Type in Profile 1/3

Human Design is comprised of multiple different components, and in terms of the Human Design journey, profiles are significant. But it’s important to have a good grounding of knowledge about the system as a whole, particularly aura type.

Learning about your profile is valuable, however it should only be considered in the context of your Human Design type. This is because the qualities of each profile manifest differently according to individual designs, and in particular energy types.

1/3 Manifestor Profile in Human Design

Pure Manifestors are unique in that unlike other types, they’re here to initiate. Not only can they, it’s correct for them to do so, otherwise they can miss out on opportunities that are perfect for them and not meet their potential.

This is why it’s so vital for the 1/3 Manifestor to follow their strategy.

The inquisitive and adventurous nature of the third line perfectly harmonises the Manifestor’s drive to initiate. 

Keep in mind however, they are likely to meet resistance from others when acting on this energy. This is why it’s so vital for the 1/3 Manifestor to follow their strategy: to inform. Doing this will ensure those around them accept and respect their actions rather than questioning them.

1/3 Generator Profile in Human Design

The 1/3 profile perfectly complements the Pure Generator type. 

The Generator strategy is to wait to respond, by tuning into their Sacral response and being guided by their inner authority.

Its spontaneity can tip over into recklessness.

The energy of the Investigator one line compels the 1/3 to figure things out through personal experiences. However, the Generator strategy can help to speed up this process by rejecting incorrect opportunities without the need to first experiment with them.

Martyr line energy is always encouraging the 1/3 to try a new experience, but its spontaneity can tip over into recklessness. Bottom line: the Generator’s strategy can help to create balance here.

1/3 Manifesting Generator Profile in Human Design

Manifesting Generators are a hybrid of the Pure Manifestor and the Pure Generator, adopting a combination of their traits.

It’s important for the 1/3 MG to resist the impulsivity of their third line.

Being a dual energy type with a defined Sacral center, MG’s not only have abundant, sustainable energy, they’re also able to direct it in multiple places at once. Manifestors do not have access to the same life force energy reserves, while Generators are not able to focus on more than one project at a time.

In order to avoid burnout created by incorrect obligations, it’s important for the 1/3 MG to resist the impulsivity of their third line, by tuning into and heeding their Sacral response.

1/3 Projector Profile in Human Design

Projectors have one of four different inner authority variations:

  • Emotional authority
  • Splenic authority
  • Self-projected authority
  • Ego or heart-projected authority

As a non-energy type, the Human Design Projector can constantly struggle with conditioning. It’s natural in this world to feel a compulsion to initiate, but as we know, this is wholly incorrect for the Projector.

It is energetically correct for 1/3 Projectors to need alone time on their journey of self-discovery. 

With the 1/3 profile, this can be an even greater challenge for a Projector: 

Their third line energy – essentially, a drive for new experiences – is always pushing to be heard, yet is basically in opposition to the essence of the Projector, whose strategy is to wait for an invitation

It is energetically correct for Projectors – and especially 1/3 Projectors – to need alone time on their journey of self-discovery. 

When Projectors have faith in all aspects of their design and embrace their strategy, they will notice that people are drawn to their expertise and authority in a subject, and their lives become far easier.

1/3 Reflector Profile in Human Design

The Reflector has no inner authority; instead they have external lunar authority which is tied to the cycle of the moon. With no defined centers, Reflectors have no sustainable energy sources, instead relying upon the energy of those around them which they’re able to take in and reflect.

For the 1/3 Reflector, leaning into their first line energy is critical.

A significant trait of Reflectors is their difficulty in truly knowing their true nature and authentic self. This is a direct result of always mirroring those around them who they admire, and this is important in the context of the Investigator Martyr profile.

For the 1/3 Reflector, leaning into their first line energy is critical for closely reading those in their sphere. Doing so enables them to determine whether or not associates should become an important fixture in the Reflector’s life.

The third line of the Martyr can interfere with this process, since it drives the Reflector to become acquainted with as many people as possible. Following their strategy – to wait a calendar month – can help the Reflector to balance out this third line energy.

Careers for Profile 1/3 in Human Design

For the 1/3 profile, any position which provides opportunities for meticulous research and new experiences can work well. Some examples may include:

  • Researcher
  • Teacher / lecturer
  • Historian
  • Biologist
  • Travel writer

What Does the Science Say?

Fascinating though Human Design philosophy is, there’s no evidence to support the theory.

However, despite this, there are many intriguing concepts within the system, some of which are grounded in psychology. Certainly, there appear to be many overlaps between the profiles and various personality profile models.

There is one Myers-Briggs personality type that stands out as being highly comparable.

With this in mind, at the end of each of my articles, I attempt to deconstruct the specific component of Human Design discussed with the post, and look for common features with accredited research.

With regards to profiles, I thought it would make an interesting project to see how they compare with the Myers-Briggs types, and whether there’s any obvious overlap. Bear in mind there are 12 different profiles in Human Design and 16 identified by the Myers-Briggs personality test1.

In the case of the specific profile outlined above, the 1/3 Investigator Martyrs, there is one Myers-Briggs personality type that stands out as being highly comparable:

ISTP, the Crafter

Fiercely independent, Crafters seek out new experiences which can provide them with first-hand understanding, knowledge, and learning opportunities. The ISTP profile clearly has traits of both the first line of the Investigator and the third line of the Martyr in common with the 1/3.

  1. Nice description! Opened a lot 😊.

    In my 20 year research I have found we should see different personality systems different, not the same. They are different angles to see what is being human.
