I've lately delved into the INFJ INFP dilemma so I thought it would be fun to ponder which letter switch results in the most differing personalities. And which letter switch seems to have the least impact. I'm speaking in generalizations of the types, not some far-end manifestations vs each other.
Naturally one (me) sets off with the functions and decides on the most different ones you can switch with one letter. I've come to the conclusion that the effect of switching a letter in order of effectiveness (from least effective to most effective) is as follows: E/I < F/T < J/P = N/S with the N/S and J/P being the most noticeable. The E/I is a matter of prominence, hence it has the least effect most of the time. F/T and N/S are matters of different functions, N/S being more apparent. J/P is a matter of opposite functions all around, so it should have the most impact, but this isn't necessarily true in all cases.
Disclaimer: Results may vary depending on type. Switching F for T on ENXP or INXJ is really similar also because its playing with the auxiliary.
Since Ni and Si are the most different interchangeable functions, we will see that the most different types are either ISFJ and INFJ or ISTJ and INTJ. From these pairings, to me, comparing the ISTJ vs INTJ is like comparing the sides of the moon. There are similarities on some level but the differences trump anything I've come into contact with. I could be biased because of personal chemistry though.
Even though the J/P switch seems like the most effective because of opposite functions, the INFP and INFJ may seem really similar by description and real people. The trophy of most similar J/P switch definitely goes to this pairing. It is to be noted that after extensive research I'm not absolutely certain (if there even is such certainty) which is which or have I ever even met a real INFJ.
Somehow it seems as if with N-types the J/P switch is less apparent than in the S-types. This is due to the perceived similarities of Ni and Ne. Take ENFP & ENFJ, INTJ & INTP, ENTP & ENTJ vs ISTJ & ISTP, ESTJ & ESTP, ISFJ & ISFP, ESFJ & ESFP.
The most similar in any switch would be the ESTJ ISTJ duo.
I didn't write down much explanations because I'm interested in how you guys see the types in relation to one another. Any thoughts?
