James Reynierse says: "You have it exactly right when you refer to the symmetry of type beginning with the Pair interactions. My colleague and fellow researcher John Harker and I have frequently discussed these relationships in terms of the natural symmetry of type... showing a circumplex structure for the MBTI is interesting and instructive" E8 and its subalgebras are mapped to MBTI types and Enneagram numbers. In the process, analogies with the use of E8 in physics are explored. Down at D3, a Process Circumplex is constructed from MBTI type pair interactions and an analogy is shown with conformal gravity and its rotation, boost, translation, and special conformal bivectors. At D4, an analogy is constructed between the Enneagram's Law of 7 (1-4-2-8-5-7) and the electroweak force. Also, the Enneagram's Law of 3 (3-6-9) is related to the color force. At D5, an analogy is constructed between the Enneagram's first (1-2-3-4) and second (8-7-6-5) quaternities and the real and imaginary dimensions of complex spacetime. At E6, the analogy constructed is between two additional Enneagram patterns and matter/antimatter. E7 and E8 relate to brane universes and perhaps to multiple MBTI type spaces encoded in the brain.
