Three pairs of dichotomies
First dichotomy: contact/distance.
The first pole indicates the predominance of the need for contact, and the second the need to maintain distance. Into the contact category will fall clearly expressed extroverts as well as extroverted introverts. Distant will be clearly expressed introverts, but also introverted extroverts – those extroverts who avoid intensive contact. The scale of vertness is thus split into four gradations.
Second dichotomy: terminating/initiating.
I understand terminating as the ability to finish what was started and a tendency towards regulation. Initiating, as the opposite tendency to initiate and to easily move on to something else, with corresponding disorder in matters and affairs. As you see, these are the concrete definitions of the usual dichotomy rationality/ irrationality. It would be incorrect to think that in the house of any rational reigns pristine order, that it clearly plans all, and that all irrationals throw everything to the side and are burdened by planning. In reality, two intervening gradations are frequently encountered between these extreme poles.
In the terminating pole belong clearly expressed rationals and orderly irrationals. Initiating behavior is possessed by clearly expressed irrationals and disorderly rationals.
And the third additional dichotomy is connecting/ignoring.
The level of sensitivity to changes in the environment is assumed to be the basis of this scale. Connectors are very sensitive to such changes, whereas ignorers, as the name suggests, are capable of turning no attention towards this.
This polarity is the subtype refinement of the classical dichotomy dynamic/static. Combining these three scales, we obtain the following four subtypes:
contact, terminal, connecting - dominant subtype (D);
contact, initial, ignoring - creative subtype (C);
distant, terminal, ignoring - normalizing subtype (N);
distant, initial, connecting - harmonizing subtype (H).
