For example, suppose a person where INTj-ESTp. Standard typing methods might detect base Ti and substantial expression of Se, leading to a typing of ISTj.
Of even greater concern to me, though, is that if one can't isolate what part of the behavior is from the "master" and what part is from the "slave," then how can one verify that the theory is correct? How do I picture what a dual type is supposed to look like or even have an idea of what a person's dual-type is if there's no way to isolate the behaviors associated with the dual types? Similarly, how do you know that my master type is Gamma-NT and that my slave type is an ethical type if the behaviors of master and slave are indistinguishable? Or...what kind of controlled circumstances would we need to be able to observe the dual type theory in action?
Another related question: How do we know that there are only 2 types (master and slave)? Can a master have two slaves? Can a slave have its own slaves? Can there be additional slaves that appear from time to time? And if not, why not?
