Sorry to be so rude (Fi maybe?), but in my candid opinion, the SP-SJ-NF-NT dichotomy is crap. The N-S dichotomy is the only thing consistent between SP-SJ and NF-NT. After that, the "NF Idealist" "NT Supergenius" "SP Hedonist" "SJ Totalitarian" classification is COMPLETELY subjective.
SP and SJ both indicate a single cognitive function. NF and NT indicate two cognitive functions, to say nothing of which are introverted functions and which are extroverted.
I suggest you have Sanguine, Choleric, Phlegmatic and Melancholic be EP, EJ, IP and IJ respectively, then have SF-ST-NF-NT for secondary temperaments. I mean, every Judger has some element of "in charge" to them. Even the ETP types, however logical and relatively unemotional, act on their own caprices.
There's no way an ESTP is Choleric and an ESFJ is Sanguine.
And I don't think INTJ is Melancholic-Choleric and the ISTJ is Pure Melancholic. ISTJs are much more prone to anger. Much more pragmatic. INTJs have to be the pure Melancholics.
The same pattern appears when comparing ESTJ and ENTJ. ENTJs are much more cerebral AND they're more cool-headed. xSTJs are known for harboring more anger than any other types. The ESTJ is the purest Choleric there is. Not Choleric-Melancholic like the chart says.

Thoughts, anyone?
