MBTI vs four temperaments

Part I: pure types

ENTJ is definitely pure Choleric, efficiently manages things and is quick-thinking.

Pure Phlegmatic is pure ISFJ, dislikes changes and is diplomatic.

Pure Melancholy is iNtuitive and Thinking. Definitely not ISTJ. Less grounded more like INFP. But still not INFP. Calculated like a Thinker. But definitely not INTJ, as INTJ is more choleric-like. So it's INTP.

We got ENTJ (TeNi), ISFJ (SiFe), and INTP (TiNe), so pure Sanguine must be ESFP (SeFi).

For now we got:

Sanguine: Se + Fi

Choleric: Te + Ni

Melancholy: Ti + Ne

Phlegmatic: Si + Fe

Part II: aspirational temperaments

If temperaments are defined by its dominant (1st) function, then each temperament has both Extroverted and Introverted blends. Each dominant function represents each type's biggest aspiration.

Sanguine: ESP and IFP

Choleric: ETJ and INJ

Melancholy: ITP and ENP

Phlegmatic: ISJ and EFJ

This quartet may be called as aspirational temperaments.

Part III: interactional temperaments

However, in most system based on 4 temperaments (e.g. DiSC, Color Code Personality), Sanguine and Choleric are divided from Melancholy and Phlegmatic by extraversion–introversion or similar, beside another scale usually called people–tasks orientation.

This way, Sanguine and Choleric are extraverted, while Melancholic and Phlegmatic are introverted. Each aspirational temperaments, meanwhile, have both Extroverted and Introverted versions. This means that there's another temperament quartet.

Assuming that MBTI's Extroversion–Introversion is the same to those of other systems, then:

Sanguine: E + X

Choleric: E + X

Melancholy: I + X

Phlegmatic: I + X

Where each X represents the auxiliary (2nd) function. Because we already know each temperament's pure types, then:

Sanguine: ESFP = ESP + EFP

Choleric: ENTJ = ETJ + ENJ

Melancholy: INTP = ITP + INP

Phlegmatic: ISFJ = ISJ + IFJ

Removing the dominant functions, we got:

Sanguine: EFP

Choleric: ENJ

Melancholy: INP

Phlegmatic: IFJ

Each temperament has to have both P and J, or some blends will be missing (e.g. Phlegmatic EFJ + Sanguine EFP, the last letters don't match).

If you notice it, certain pairs of pure temperaments share both the same 2nd and 3rd letters (ISFJ–ESFP and ENTJ–INTP). Thus it can be said that S/F–N/T somehow analogous to people–tasks orientation. Sensing and Feeling are more ‘engaging’ with people and environments than iNtuition and Thinking are. And since in this quartet we use the auxiliary functions, the scale become Sj/Fp–Nj/Tp. Note the small j/p; they mean xxxj = ExxJ/IxxP and xxxp = ExxP/IxxJ.

Sanguine: ESJ or EFP

Choleric: ENJ or ETP

Melancholy: INP or ITJ

Phlegmatic: ISP or IFJ

This quartet may be called as interactional temperaments.

Part IV: blends

The two quartets can be combined to make a temperament blend that has a different interactional temperament from its aspirational temperament, e.g. interacting like a Phlegmatic but has the aspiration of a Sanguine. Since most systems based on the 4 temperaments usually use the extroverted-vs-introverted format, here the interactional temperaments come first.

So the blends are:

Sanguine: ESFP

Sanguine-Choleric: ESTJ

Sanguine-Melancholy: ENFP

Sanguine-Phlegmatic: ESFJ

Choleric: ENTJ

Choleric-Sanguine: ESTP

Choleric-Melancholy: ENTP

Choleric-Phlegmatic: ENFJ

Melancholy-Sanguine: INFP

Melancholy-Choleric: INTJ

Melancholy: INTP

Melancholy-Phlegmatic: ISTJ

Phlegmatic-Sanguine: ISFP

Phlegmatic-Choleric: INFJ

Phlegmatic-Melancholy: ISTP
