What is my Enneagram tri-center? Gut, heart, head center tests


Enneagram Centers

Often referred to incorrectly by Enneagram enthusiasts as Trifix or Tritype (they're actually more specific trademarked implementations), the tri-center approach to using the Enneagram types identifies three types instead of simply one. With this approach the three types come from each of the centers (often referred to as a gut or body type, a heart type, and a head type).

Because your basic type is the dominant type in one center, the dominant types in the other two centers need to be determined with this approach. The gut type will be either 8, 9, or 1. The heart type will be 2, 3, or 4. The head type 5, 6, or 7.

While you still are your basic type, you can also think of yourself as a specific variation of that type by looking at the two other center types. For example, someone identifying as type 1 with a tri-center of 1-2-5 will be similar to someone identifying as 1-4-7 because both their basic types are 1 but they will also be different because their other two center types are different (i.e., 2-5 vs. 4-7).

Wings may also be combined with this approach as well. For instance, including the preferred wings for 1-4-7 may result in something like 1w2-4w5-7w6.

Tests that explicitly suggest tri-center

Some test results will suggest your tri-center or tri-center with wings.
