The Juxtaposition Cross of Experimentation is named here for Gate 16 and Gate 9. Its first article reads Gate 16 as enthusiasm refined by repetition into real skill, now the more exposed gate, and Gate 9 as the capacity to attend to the small detail a larger idea depends on. What it does not trace is where the four gates sit on the wheel itself, the Human Design mandala's division of its sixty four gates into four Quarters, and by that measure this cross draws one gate from each of the four.
Gate 16, the personality gate here, falls in the Quarter of Civilization, purpose fulfilled through form. Gate 9, its personality partner, falls in the Quarter of Mutation, purpose fulfilled through transformation. Behind them, Gate 63 falls in the Quarter of Initiation, purpose fulfilled through mind, and Gate 64 falls in the Quarter of Duality, purpose fulfilled through bonding.
So the refined skill and the attended detail the first article reads on this cross's surface answer to the arcs of form and transformation, while the questioning mind and the confusion still working toward clarity beneath them answer to the arcs of mind and bonding, the same two design gates the Juxtaposition Cross of Doubts carries as its own personality half. The same pair, exchanged, is this cross's own reversal, the Juxtaposition Cross of Focus, and, held instead in the Left Angle family, the Cross of Identification, and in the Right Angle family, the Cross of Planning. Four gates, four different Quarters, no pair sharing an arc: this cross draws its whole reading from every corner of the wheel's own purpose rather than concentrated in one.
