Finding Which Process
Is Dominant
There are three ways of deducing the dominant process from the four
letters of a person’s type. The dominant process must, of course, be either
the preferred perceptive process (as shown by the second letter) or the
preferred judging process (as shown by the third).
The JP preference can be used to determine the dominant process,
but must be used differently with extraverts and introverts. JP reflects
only the process used in
dealing with the outside world.
As explained earlier,
the extravert’s dominant process prefers the outer world. Hence the
extravert’s dominant process shows on the JP preference. If an extravert’s
type ends in J, the dominant process is a judging one, either T or F. If the
type ends in P, the dominant process is a perceptive one, either S or N.
For introverts, the exact opposite is true. The introvert’s dominant
process does not show on the JP preference, because introverts prefer not
to use the dominant process in dealing with the outer world. The J or P
in their type therefore reflects the
auxiliary
instead of the dominant
process. If an introvert’s type ends in J, the dominant process is a
perceptive one, S or N. If the type ends in P, the dominant process is a
judging one, T or F.
