I would just like to add that I believe anal/accepting types are more likely to receive benefit/supervision, whereas oral/creative subtypes are more likely to produce it. Also, note that introversion is defined as extroversion-creating, introversion-accepting, whereas extroverts are the opposite; from here it was pretty easy to deduce that I am in fact LIE, possibly oral subtype...
It makes perfect sense that anal types focus more on what they accept and oral types on what they produce. Information follows the direction of process result; result types somewhat randomly create finished products in an unfocused manner while totally unaware of what they are doing, whereas process types will focus their unconscious on one phenomena and become completely involved only in metabolizing it away without ever realizing any particular aspect of their own results.
There is more to the conscious mind than a random distribution of cognitive preferences...
I had believed that fundamental emotional ties to IM associated with the dopamine reward-path and the id were responsible for the higer cognitive order, but I am not entirely sure...however, I do know identical twins that have different types; the truth is, usually people who grew up together had similar personalities because they produced and responded to the same type of information, which was conditioned into their minds. In my family, which is predominantly beta, me and my sister are gammas; I have always been something of a free thinker. I believe that many aspects of VI, such as facial expressions and facial development, might be tied to bloodflow and muscle use adapted in the brain to the types of physiological accommodations that support a particular IM in all habits and activities and on a daily basis.
I believe that you have overlooked the profundity of this thread; quadra progression is a necessary consequence of the types of cognitive structures that exist in the mind, which mostly exist to accommodate a personal preference with respect to the speed and manner in which new information is integrated. It is the basis for the entrenched ego/superid 'walls' that people put up to accommodate their own id/superego biases that eventually leads to inter-quadra conflicts, as betas and deltas focus on different methods of agency (immediate versus prolonged) and alphas and gammas on different approaches of manifestation (dogmatic versus critical).
Sorry, I know quicklier is not a word, but I prefer it to quicker.
