The MBTI segments the mind into 8 pieces and 16 more pieces for each archetype. We call it "self-actualization", though the only thing to be actualized is a projected system. Those who inspect the system are too slothful to inspect themselves; so they wallow in self-stagnation - attempting to improve the system rather than themselves.
When the brain of the individual is lobotomized in such a fashion as the functional theory, the synapses fire and redirect signals from sender to sender, rather than from sender to receiver. Perhaps the signals are diffused in the empty cavities of division.
Likewise, each archetype worship themselves; not themselves per se, but an idolized version of themselves. The NFs with the NFs, the NTs with the NTs, the SJs with the SJs, and the SPs with the SPs.
Consequentially, those who worship MBTI become confused and convoluted like the segments of the brain. So when each segment worships itself, the societal brain deteriorates and falls like Rome did after its warlords succumbed to greed.
Society operates like the individual operates, as Maslow's hierarchy of needs suggests: The SPs provide physiological needs, the SJs provide security, while the NTs and NFs accentuate self-actualization and creativity. The individual may accomplish every need for sustenance, but the whole cannot operate without specialized individuals.
To avoid this depraved and false self-worship, we must reconcile ourselves and do away with the dialect of MBTI -- as the 8 functions are like the 8 colonies.
