Type 2 and Type 6: Center Dynamics and Arrows
The Two belongs to the heart triad, driven by the need to be loved. The Six belongs to the head triad, driven by the need to be secure. Both are compliant types (along with One) in the Hornevian groups — they move toward others and orient themselves by external expectations and loyalties. The Two's arrows point to Type 8 (integration) and Type 4 (disintegration). The Six's arrows point to Type 9 (integration) and Type 3 (disintegration). Under stress, the Two becomes withdrawn and self-pitying (Four), while the Six becomes image-conscious and competitive (Three). These stress responses are different enough that they don't amplify each other — which is actually a strength, as one partner's stress mode doesn't trigger the other's.
