There are three methods of looking at DCNH subtypes:
1.) Dichotomies
DCNH is a sub-temperament theory. That means that, for example, the EJ-subtype is more extraverted and more judging than an average representative of a particular main type.
2.) Adjectives
The EJ-subtype is also called the Dominant subtype. But as I tried to clarify
in this thread, the adjectives should not be taken literally. Not every IP-subtype is really "harmonizing", not every EP-subtype is really "creative".
3.) Information elements
Gulenko explains that, for example, the EJ-subtype has strengthened
and
. He says that
,
,
and
are "strengthened in pairs". The problem is, if you expand the DCNH system logically you can easily get 8 and 16 subtypes - but you will come to a different conclusion:
A D-ENTp, for example, is nothing but an ENTp-Exxj if you want to use 16 subtypes. That means that a D-ENTp can be an ENTp-ENTj, ENTp-ESTj, ENTp-ENFj or ENTp-ESFj. (I hope everyone agrees so far).
The problem is that ENTp-ENTj and ENTp-ESTj, theoretically but also practically, have much stronger
but unfundamentally weaker
than an average ENTp. For ENTp-ENFj and ENTp-ESFj it is the other way round: They have much stronger
but insignificantly weaker
than an average ENTp.
Conclusion: Using the DCNH system it makes more sense to say that, for example, the D-subtype has
either much stronger
or much stronger
than an average representative of a particular main type.
