Your tri-center consists of your dominant type in each of the three centers of intelligence with a preferred ordering of the centers (types). The preferred ordering of the 3-7-9 is:

1. Primary Center: Heart (Type 3)
2. Secondary Center: Head (Type 7)
3. Tertiary Center: Gut (Type 9)

Type 3 is located in the 234 triad which is often described as the heart or heart-based center.

The heart types are focused on interpreting, expressing, and reacting to one’s own emotions or the emotions of others. More specifically, the heart center focuses on what's emotionally significant in the sense that emotions are an indication of how strongly a person resonates with or against something or someone.

This may involve being attentive to the emotional needs and desires of others, seeking emotional affirmation for oneself from others, and expressing one's own unique emotional impression of the world.

Type 3 often puts aside personal feelings that might get in the way of pursuing goals. Yet, they may also seek emotional affirmation or validation through recognition from others. Although accomplishments and the overcoming of challenges on their own can increase a sense of self-esteem, it can be hard to know how well they are performing without some external indicator, such as awards or recognition, to affirm their effort and value.

Type 3 Shame

The shame triad consists of types 2, 3, and 4. Shame for these types involves the heart center. It can be thought of as a feeling of deficiency for not living up to a more idealized sense of self.

This may involve initiating connection with others to avoid feeling unlovable or unimportant in the lives of others, finding value and worth through performance and accomplishment, and finding significance by cultivating and expressing one's uniqueness.

Type 3 shame can come from a sense of failure in achieving a goal or gaining recognition. Although failures can sometimes be spun as simply lessons to be learned or simply a speedbump along the way to success, there can also be an avoidance of pursuing endeavors that risk failure in favor of those with less risk.

Type 7 is located in the 567 triad which is often described as the head or head-based center.

Although the head types can be thought of in terms of reasoning, analyzing, and other typical thinking functions, a useful distinction from the other two centers can be made in terms of anticipating and preparing for future possibilities.

This may involve gathering data and facts in order to better predict outcomes, preparing for negative potentialities that might occur, and planning or pursuing activities that provide enjoyment and avoid discomfort.

Type 7 avoids pain and limitations while seeking what's interesting and exciting. It's hard to commit to just one thing. Options are kept open because there's always the possibility of an interesting opportunity suddenly presenting itself. When interest in what's going on begins to wane then attention can quickly turn to what's next. There can be a living in the future approach to life where the type 7 wants to always have something exciting to look forward to.

Type 7 Fear

The fear triad consists of types 5, 6, and 7. Fear for these types involves the head center. It can be thought of as a negative anticipation of future possibilities and wanting to prepare for or avoid those possibilities.

This may involve learning as much as possible in order to feel competent and knowledgeable, imagining worst-case scenarios and preparing for them, and having alternatives available to avoid being trapped in discomfort or pain.

Type 7 has a fear of pain, boredom, and limitation. The future is anticipated and choices are made that avoid the negative and pursue the positive. Often when a choice has the possibility of going down a path that leads to what's feared, they'll quickly choose another path or distraction that avoids it.

Type 9 is located in the 891 triad which is often described as the gut or body-based center.

There are several ways to interpret what the gut or body types represent. They may be thought of in terms of sensory-somatic (bodily felt sensation), sensory-motor (physical movement and activity), or instinctual (gut decision making).

This may involve taking action based on one's gut instinct, getting pulled along by the agenda of others, and actively trying to correct what's seen as wrong in the world.

Type 9 often seeks physical comfort and routine. There can be an inertia when it comes to physical activity. When at rest they tend to stay at rest and when moving they tend to maintain that movement. In other words, they may stubbornly resist doing what they don't want to and fall into routines which they dislike having interrupted. They often have difficulty setting and following through on personal goals. Instead, there can be a tendency to get carried along on the energy and agenda of others.

Type 9 Anger

The anger triad consists of types 8, 9, and 1. Anger for these types involves the gut or body center. It can be thought of as an energy of will that pushes against obstacles to create movement or resists being pushed.

This may involve pushing through obstacles to get what one wants, stubbornly resisting attempts to be pushed in an undesired direction, and getting people to see what's right and correcting things not done right.

Type 9 is said to fall asleep to their anger. Because they generally don't have a strong personal agenda, they tend to simply go along to get along instead of making an effort to overcome obstacles in pursuit of a goal. However, they can push back in resistance, through a stubbornness or passive-aggressiveness, when they are confronted to do something they don't want to.

Striving-Anticipating-Accommodating

The tri-center focus looks at your dominant type in each center through the core focus.

Type 3 Initial Self-Belief: “I am not valued as I am.”

Type 3 Compensation: "I must become accomplished and prove myself to gain value and regard in the eyes of others."

Type 3 Core Focus: Esteem comes from being valued and having the positive regard of others. This requires that I not only package myself and perform in ways that will garner that recognition and positive regard but also find ways of measuring my success toward those ends.

Personality characteristics that might arise from the type 3 core focus:

• Looks to external indicators for how well they're performing.
• Packages and markets self-image that's admired by intended audience.
• Pushes aside feelings that get in the way of achieving goals.
• Sense of self-value comes from what they produce or accomplish.
• Competes in arenas where there is someone to beat and someone to notice.

Type 7 Initial Self-Belief: “I am not satisfied as I am.”

Type 7 Compensation: "I must stay open to exciting possibilities that may become available in life and avoid limitations on my pursuits."

Type 7 Core Focus: Enthusiasm comes from possibilities that lead to something interesting, exciting, or satisfying. This requires that I anticipate whether a path might lead to something positive or negative. The positives are pursued while the negatives are avoided, reframed, or escaped from.

Personality characteristics that might arise from the type 7 core focus:

• Likes to keep options open for fear of missing out in life
• Escapes pain and boredom by quickly moving on to something else
• Avoids commitments/obligations that feel limiting and restrictive

Type 9 Initial Self-Belief: “I am not in unity as I am.”

Type 9 Compensation: "I must accommodate others' agenda and opinions in order to feel at ease and in harmony with them."

Type 9 Core Focus: Harmony comes from getting along with others and falling into comfortable routines. This requires that I accommodate others by finding common ground and minimizing my own agenda when around others as well as finding comfort and peace of mind for myself.

Personality characteristics that might arise from the type 9 core focus:

• Loses sight of own agenda in favor of the agenda of others
• Smooths over conflict in order to keep the peace and feel more at ease
• Has difficulty establishing goals and following through on them

• Supresses anger which may surface as stubbornness or passive-aggressiveness
• Finds it difficult to prioritize because everything can seem equally important
• Numbs themself through comfort seeking and getting lost in routine
