What exactly is your argument for the tertiary being oriented in the same direction as the auxiliary?
This seems unlikely because it gives everyone two kinds of the same type of function before the other ever comes up at all:
EPs would be: Pe Ji Ji Pi
IPs would be: Ji Pe Pe Je
EJs would be: Je Pi Pi Ji
IJs would be: Pi Je Je Pe
So EPs don't even have a form of Je without delving into shadow functions? IPs don't have Pi, EJs don't have Pe and IJs don't have Ji? It should be intuitively obvious that this doesn't really make sense. In function theory there are four kinds of cognitive approaches:
1) Extroverted Judgment, which deals with applying objective structure and order to the external world,
2) Introverted Judgment, which deals with making subjective value judgments about logic and ethics,
3) Extroverted Perception, which deals with focusing on a wide range of different contexts at once to keep options as open as possible,
4) Introverted Perception, which deals with focusing on one context and interpreting the essence of its meaning and significance for you personally.
It's clear that each of these abilities needs to come into play in some way for each person, but what I don't understand is why two different methods of the same task would both take precedence over the primary method of one of the other three.
