2 ideas here, so try your best not to get confused. I will bold where one starts and the other starts.
4 out of 16 types have the same 4 primary functions respectively (ordered originally), and hints of using all 4 of these and almost disregarding the other 4. So let's make four unified groups.
Maybe we can see similarity in answers and opinions that way in our forums, if we bunch these people together. Recognizing for instance, an Fe interaction with Ni, and relating closely to it even for an ISTP.
So... why not rename the personality types based on function understanding? Using three letters I can make this simpler to write out or regard for anyone.
ENTJ - ETN (extraverted thinking with intuition)
ENTP - ENT (extraverted intuition with thinking) easy enough?
if we have dislexic people, why not try...
ENTJ - NET (intuition with extraverted thinking)
then place the E the same as the first for ENTP, keeping perceiving function at the front...
ENTP - ENT (thinking with extraverted intution/ the E specifying that they are extrovert and therefore EN states having extraverted intution as primary.)
INTP - NIT (introverted thinking with intution) intuition obviously is extraverted
Then we have four common groups, besides the Rational, Guardian... etc. (that is one major identity) but groups of common thought process based on function.
Let's decide on names for these
Group one - extraverted N and T (extraverted rationals? heh I'm joking based on the extraverted functions... let's say logically tuned to possibilities?)
ENF - ENFP
NIF - INFP
SET - ESTJ
IST - ISTJ
all having Ne, Te, Fi, Si
Group two - extraverted N and F (emotionally tuned to possibilities? )
ENT - ENTP
NIT - INTP
SEF - ESFJ
ISF - ISFJ
all having Ne, Ti, Fe, Si
Group three - extraverted S and T ( logically tuned to surroundings? )
ESF - ESFP
SIF - ISFP
NET - ENTJ
INT - INTJ
all having Ni, Te, Fi, Se
Group two - extraverted S and F ( emotionally tuned to surroundings? )
EST - ESTP
SIT - ISTP
NEF - ENFJ
INF - INFJ
all having Se, Fe, Ti, Ni
(sorry if the renaming of type is unnecessary, I happen to like the idea because it cuts off an extra letter and identifies a type by function relationship. I mainly like the four group idea based on alike functions without reference to order)
If we could organize forum rooms like this, it could get interesting, because not only are extroverted functions in these groups the same, introverted functions are as well. A different reference point may be inspiring to one with a distant reference point for a specific function.
