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 7 Mental Center

The core focus of the Enneagram types labels the 567 triad as the Mental Center to more clearly differentiate how those types use that center.

• Type 5: Mental Observation - observes the world by pulling back from it and watching.
• Type 6: Mental Questioning - probes to alleviate doubts and find what can be trusted.
• Type 7: Mental Possibility - avoids limitations while exploring interesting possibilities.

The Thinking Triad¹
Types Five, Six, and Seven are concerned with anxiety (they experience a lack of support and guidance). They engage in behaviors that they believe will enhance their safety and security. Underneath their ego defenses these types carry a great deal of fear.

Mentally Based Intuition: Points Five-Six-Seven²

• Five - Detaching attention from thoughts and feelings in order to impartially observe. Mentally witnessing without interference from personal thoughts and feelings.
• Six - Seeing the unspoken intentions that lie beneath a surface facade. Using the imagination as a tool for unmasking hidden points of view.
• Seven - Knowing the fit between remote associations. A problem goes on the back burner of the mind while other activities continue. Something in a secondary task sparks an association that solves the original problem.

Head Center³
If you are a Head Center type (Five, Six, or Seven) you tend to filter the world through the mental faculties. The goals of this strategy are to minimize anxiety, to manage potentially painful situations, and to gain a sense of certainty through the mental processes of analyzing, envisioning, imagining, and planning. When threatened, fear and anxiety occur.

The Fear or Head Triad (5, 6, 7)⁴
These numbers are driven by fear: Five externalizes it, Six forgets it, and Seven internalizes it. They take in and relate to the world through the mind. They tend to think and plan carefully before they act.

The Head or Thinking Center (Fear)⁵

• Fives rely on their own resources and find safety in knowledge.
• Sixes seek relief from fear through the permission and approval of authority figures or through rebelling against authority.
• Sevens are active and optimistic. They shun unpleasant emotions, including fear.

The “head” center or “intellectual” center (Points 5, 6, and 7)⁶
regulates the thinking function: the experience and expression of thoughts, beliefs, and other cognitive activity. While essential for dispassionate analysis and reasoning, this form of intelligence can paralyze you if you get caught up in overanalyzing a situation.

The Head Type

If your primary or basic Enneagram type is 7 then your primary center is the head center and type 7 is your head type.

The remaining two types in your tri-center will come from the other two centers.

The Gut Type

Your gut type will be type 8, 9, or 1.

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.

The Heart Type

Your heart type will be type 2, 3, or 4.

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.
