1) I don't buy the hypothesis that Information Element use is a preference. I think it's related to inborn conscious awareness, forces the brain to mediate it's activities in relation to it, and correlates to a very simple cognitive model.
2) Basic Neuroscience tells us the lion's share of information transfer is driven by 3 major neurotransmitters. Dopamine, Serotonin, and Noradrenaline. Why should we expect to find a conveniently symmetric 8-way split characterizing it's psychological output?
3) It's much too adaptable that people can disregard anomalous behavior such as brain lesions, cognitive disorders, and brand new fitness-preserving genetic mutations by saying 'Nope, we magically accounted for it with this conveniently symmetric 8-way split'
4) There is no regular updating of MBTI by it's main theorists that attempts to integrate novel develelopments or observations meaning it's imperative that individuals with MBTI knowledge use personal initiative to connect the dots together.
5) The field of mathematics is a perfect example of how people leverage differing faculties, mental models, and representational syntax/semantics to form more and less clear views of structured phenomenon and cognition. The field of study you ignored yesterday was the solution to your problems today.
6) All this is just to say that sometimes it takes just the right person for the brain to self-model, such as someone with a DRD2 gene mutation that disrupts Dopamine habituation.
