I certainly don't consider Michael Pierce a good MBTI source.
As one jaw-dropping example, he's got a long
E vs. I video where his main illustrative example of extraversion vs. introversion involves two jungle explorers, where one explorer is to be tasked with writing down their "personal, subjective interpretations" (emotional, philosophical, theoretical, etc.) of the things they encounter, without being concerned with anything like an accurate representation of the things' objective, physical qualities, while the other explorer is to be tasked with meticulously recording
only the objective, physical qualities of the things they encounter.
And Pierce's perspective is that, if one of the explorers is an extravert (let's say an ENFP) and one is an introvert (let's say an ISTJ), you should choose the ENFP to be the meticulous, just-the-facts recorder and choose the ISTJ to be the one who, as Pierce describes it, ignores the objective facts and records stuff like "how she thinks the creature appeared rather horrid, and how that seems to reflect an interesting idea about possible morality and justice in the animal kingdom, and the philosophical implications of such a thing, and how this compares with her personal values and ideas."
And the way for a guy to arrive at that kind of blinkered perspective on ENFPs and ISTJs to is to spend too much time poring over Jung's works (like some medieval Biblical scholar), while both ignoring the many changes Myers (rightly) made to Jung's original type concepts, and maybe more importantly, failing to get out much and actually interact with any significant number of real-world ENFPs and ISTJs.
I believe Isabel Myers would have said that, in choosing which explorer was best suited to which of those two tasks, the S/N (first) and T/F (secondarily) preferences were the most significant ones, and that an ST was best suited for exclusively focusing on "just the facts" and the NF was best suited to be the recorder of subjective emotional/aesthetic/philosophical impressions — and that that two-explorers example was a very poor one to choose as an illustration of "extraversion" vs. "introversion."
And if that's what Myers would have said, she would have been correct.
And anybody who's of the view that, pffft, personality types are just a matter of
opinion anyway, and one wanker's MBTI is just as good as another's — so there's nothing wrong with Pierce just keeping his nose in his books and emerging every few days or so to make another picture-filled video — are hereby advised that, in fact, personality psychologists working in the respectable districts of the field have actually been
validating typologies by means of psychometric analysis of suitably large samples for many years now. McCrae & Costa (the leading Big Five psychologists) long ago acknowledged that the MBTI's dichotomies (unlike Jung's original concepts) basically passed muster by modern standards, and a very large meta-review and supplemental study in 2003 found that the MBTI was more or less on a par with the Big Five from a psychometric perspective.
And for anyone who's interested, there's more discussion of those kinds of issues
here.
But unlike the dichotomy-centric perspective that's always dominated the
official MBTI and its use by academic researchers, the so-called "cognitive functions" have no respectable body of empirical support behind them. And in particular, the Harold Grant function stack — the one that says INTJs are Ni-Te-Fi-Se, INTJs and INTPs have
no functions in common, and INTJs and ESFPs have quite a lot in common because they're both "Fi/Te types" and "Ni/Se types" — predicts correlational patterns that virtually never show up, no matter what aspects of personality anybody's correlating with MBTI types.
And Pierce is a wholeheartedly wanktastic subscriber to that function stack and its corresponding "axes," and spends quite a lot of that linked video talking about an INTJ's "tertiary Fi" and "inferior Se" — not to mention their "shadow ISFP," which leads them to share with ISFPs, in Pierce's words, "this need to express things that are extremely difficult to express." Yeah, baby ... unlike INTPs (since they're "Ti/Fe" and "Ne/Si" types), and INFJs, whose "Fe" means those two introverted types mostly don't experience that typical INTJ "need to express things that are ... difficult to express."
Like the similarly wanktastic Linda Berens with her latest "lens" (which she calls "Intentional Styles"; discussed in the next linked post, below), Pierce groups INTJs and ESFPs together — socionics-quadra-style, baby — in a foursome that he refers to as the Conjecturing (Ni/Se) and Operationalizing (Fi/Te) types, while putting INTPs and ESFJs in the opposite quadrant, as the Examining (Si/Ne) and Translating (Ti/Fe) types.
I'd say it takes a singularly
piercing (pardon my pun) perspective on the types to see deep enough down into the psychic depths to realize that, when it comes to personality cousins, it's INTJs and ESFPs who belong together, and not INTJs and INTPs (or ESFJs and ESFPs).
Or maybe not.
And for anyone who's interested, there's more discussion of the bogosity of that function model — not to mention its inconsistency with both Jung and Myers — in
this post.
And speaking of Jung and Myers, it's maybe also worth noting that the "Sources" Pierce lists at the end of that INTJ video include Jung's
Psychological Types (not to mention CelebrityTypes.com) — but funnily enough, there's no mention of Isabel Myers.
Or maybe that's not very funny, now that I think about it.
As discussed in those previously-linked posts of mine, Carl Jung — mystical streak notwithstanding — was a believer in the scientific approach, and Myers took
Psychological Types and devoted a substantial chunk of her life to putting its typological concepts to the test in accordance with the psychometric standards applicable to the
science of personality. Myers adjusted Jung's categories and concepts so that they better fit the data she gathered, and by the start of the 1960s, she had a typology that was respectably tapping into four of the Big Five personality dimensions — long before there really was a Big Five.
The aspects of Pierce's characterizations of INTJs in that video that can make the most respectable claims to applying to many real-world INTJs owe at least as much to Myers' corrections, adjustments and expansions to Jung as to Jung's original conceptions of his types — and Pierce's failure to acknowledge that doesn't speak particularly well for him.
As one big example, and as discussed at length
here, Jung didn't think an Ni-dom would have Te — or any other extraverted function — as their auxiliary.
And related to that Jung/Myers difference, the qualities of personality that get someone typed J on the MBTI were ones Jung associated with J-doms generally — rather than Je-doms and Pi-doms, as Myers had it. So what you might call the "best fit"
Jungian type for an MBTI INTJ is really a Ti-dom (with an N-aux), rather than an Ni-dom.
But if you're willing to indulge Pierce with his "Ni-Te" (i.e., Myersian) framing for an INTJ while simultaneously looking to
Jung's function descriptions to understand what that would mean, then it must be noted that, far from "auxiliary Te" giving INTJs the "drive" and "tenacity" to follow through on their Ni-based visions and "actualize" them (as Pierce describes things), Jung said that, with or without an auxiliary in gear, an Ni-dom's visions tended to be too far out of touch with "present-day reality" to be realizable, with the result that, in the typical case, the Ni-dom ended up being a "voice crying in the wilderness" — which is why Jung also noted that, from the standpoint of actually accomplishing anything in the real world, Ni-doms were understandably viewed (together with their "introverted irrational" cousins, the Si-doms) as the "most useless of men."
Now, it's true that Pierce acknowledges — while constantly referring to, quoting and paraphrasing Jung — that he's hardly a
strict Jungian (and a good thing, too), but that hardly excuses his frequent mischaracterizations of Jung's views, which go hand in hand with the underlying implication that his own function model and corresponding descriptions are far more Jungian than they really are.
The bottom line is that Pierce is basically one more in the tiresome parade of online MBTI "theorists" in the Berens/Nardi mold, peddling one version or other of the myth that pretty much all Myers did was find a nifty way to test for
Jung's cognitive functions, and then serving up a mishmash of type notions in a way that reflects a startling lack of understanding of what Jung actually said, of the changes Myers made to Jung, and of the things that 50 years of actual MBTI data has taught us about what the types are like — and maybe more importantly, that reflects a disheartening lack of respect for the extent to which (as Myers very much understood, and demonstrated) the personality field can be governed by respectable scientific (albeit soft-scientific) methods.
As a final note, Jung spent more of
Psychological Types talking about the things he thought
all extraverts tend to have in common, and
all introverts tend to have in common, than he spent talking about all eight of the functions put together. And Myers' psychometric analysis led her to the conclusion that it was the four dichotomies, rather than the functions, that appear to be the principal underlying components of type.
But Myers also recognized that there were notable personality characteristics associated with various dichotomy
combinations.
Gifts Differing includes countless references to things that INs, ESs, NFs, STs, ITs, ESFs, ISTs and types with various other preference combinations tend to have in common, and the 1985 MBTI Manual (which Myers co-authored) included a brief description corresponding to each of the 24 possible two-letter combinations. What's more,
Gifts Differing also includes Myers' explanation for why she believed that the most significant dichotomy combinations were NF, NT, SF and ST — a foursome that is noteworthy in the sense that each member consists of four types with four different "dominant functions." So Myers certainly didn't
omit the combinations — e.g., NJ (Ni) and TJ (Te) for an INTJ — that supposedly correspond to the functions, but she hardly treated them as if they were the exclusive (or even the main) contributors to the MBTI-related aspects of someone's personality.
Which leads me back to Michael Pierce, and the fact that virtually his
entire 24-minute description of INTJs consists of the personality characteristics that he claims are associated with Ni, Te, Fi and Se.
What about the things all introverts tend to have in common, Mr. Pierce? Both Jung and Myers — not to mention the Big Five folks — are pretty big on those.
*crickets*
Well, you know, maybe he felt sufficiently embarrassed after he made that
jungle explorer E/I video I already talked about that he decided he'd keep his mouth shut on introversion for at least a while.
What about the things all NTs tend to have in common, Mr. Pierce? Both Myers and Keirsey had quite a lot to say about those.
*crickets*
And what about N and T and J and IN and IT and IJ?
*crickets*
Hey, those components I've asked about don't correspond to anything in that HaroldGrantian function foursome, do they? How silly of Jung, Myers or me to think they'd correspond to any personality characteristics worth mentioning.
But honestly, Mr. Pierce, and although I'm about as far from a Linda Berens fan as it is possible to get without falling off the edge of the Earth, I can't resist pointing out that
even Linda Berens knows better than to totally ignore any of the dichotomies. And she also finds room for Keirsey's foursome, among other respects in which her total (multi-"lens") perspective on personality, although it foolishly
includes the Harold Grant stack, also benefits by venturing beyond it into some of the more psychometrically supportable districts of the MBTI.
