By "comfortable," I mean to accept without resistance the nature of one's type, i.e., the cognitive functions and how they manifest based on stacking. For the sake of this discussion, I'm only talking about an inner (mental, psychological, neurological) feeling of ease and naturalness with one's cognitive type.
As far as the factors that contribute to one's "comfort-ability" with their type, I'm barring:
1.) Inadequate profile descriptions > whether due to (personal/social/cultural) type bias, a lack of complete, in-depth and nuanced information (which could lead to misattributing certain traits to the wrong type), or being too skewed towards a certain demographic (college students, corporate world, pinterest/tumblr addicts obsessed with fanciful, hyperbolic archetypes).
2.) One's upbringing > e.g., being an XNTP raised by XSFJs and therefore being exceptionally self-conscious about how their facility with Fe or lack there of is perceived.
3.) Projection of an idealized self > who you wish you were/aspire to be but aren't.
I'm an ENTJ with combined inattentive/hyperactive-impulsive ADHD and can therefore (theoretically, in so much as there are correlations between Ne/Se and "ADD"/ADHD) ostensibly appear to be an ENTP or ESTP, depending on the context. Of the two, I relate more to the ENTP and for a while, went back and forth over the plausibility of that being my type until I realized (thanks in part to the help of an ENTP friend of 15 years) that though many of our behaviors are similar, our thinking is still different, sometimes egregiously so.
My ENTP mate seems fine with a "chaotic" living space; it's not that he doesn't like things to be neat, tidy and organized, he's just also completely OK, unfazed and unbothered when they are not--for him, it's "organized chaos." When I'm hyper-focusing on a particular idea/project/endeavor, I can let things get messy and disheveled, but everytime I become re-attentive to the environment, I can't help but notice and be irritated by every flaw, every item out of place, everything that must be corrected, to the point where it becomes stress inducing to ignore it any further. For me, a clear, well organized space = a clearer, more organized mind. My ENTP mate doesn't mind inviting people into a crazy, hellish looking environment but I, on the few occasions where there was no other choice, was embarrassed, extremely self-conscious and worried that it would reflect poorly on my ability to "keep it together."
Correct me if I'm wrong, but I thought that a part of being an ENTP was possessing a certain comfort with various brands of environmental disorder (unconscious inferior Si); The few people I know who are definitively ENTPs seem to be quite OK with it. Even I can use "chaos" to my benefit if so inclined, but I'd much rather everything be well structured. I know that there is intra-type diversity but what kind of ENTP would be an environmental control freak? In order to be an ENTP, shouldn't there be an inner "OKness" with being prone to dishevelment?
It just seems to me that one should possess an inner peace with their type; And inner peace primarily via acceptance, which doesn't mean that it must be actively liked or that certain maladaptive things can't be changed--fundamentally, we should be OK with who we are. But if a cognitive function/stacking causes out and out distress, is that not potentially a sign that one is mistyped?
