All types are not created equal—at least in terms of how they relate to the three Centers of Intelligence and, therefore, how they are out of balance. The way we move around our triad can be described as a particular pattern of motion. Some of the types have one pattern of motion and some of the types have a different pattern of motion.
I call the types connected by the lines of the hexad (1, 2, 4, 5, 7, and 8) Exterior types because they’re located at either end (the exterior) of their respective centers:
8 and 1 in the Doing center
2 and 4 in the Feeling center
5 and 7 in the Thinking center
I refer to the types connected by the lines of the triangle (3, 6, and 9) as Interior types because they’re located in the middle (interior) of their respective centers.
Exterior Types
Exterior types are pretty straightforward. A Type 2, for example, could have a 1 wing or a 3 wing (meaning it could be strongly influenced by one of the types on either side). Or it could be a straight-up 2 with no wing. And as is true with all types, a 2 can be high-functioning, low-functioning, or somewhere in between. What is true for all Exterior types—but not true for Interior types—is that each Exterior type always has the same stress point and the same security point. All 2s, for example have 8 as their stress point and 5 as their security point. Continue reading
