My family is neither of those but are still traditionalists in many ways.
My core family (parents & siblings) is completely N by a bizarre stroke of luck (I say lucky for me) but the rest are somehow magically a congregation of ESTJ entrepreneurs and 1 ENTJ with an esteemed position, except for one quiet, reserved
ISTJ and an ESFP 'oddball'... Both of whom still are business owners.
The ENTJ sticks out in my family like a sore thumb, too. She is the 'weird, different, but effective' one.
The family disagrees with her (in terms of how to run things), but respects her and let her do her own thing because 'results don't lie'.
How do N types live in highly traditionalist, insulated communities?
I don't. My parents don't, either. I, at least, escape as many family meetings as socially possible.
The aforementioned ENTJ also realizes that she doesn't 'click' with the family, but says people just work differently and she just follows her own vision of what is right.
Oooohh, this is a good question. I actually think that Ns could be equally as drawn to such communities because of an attractive vision. Although, I see them "thriving" more in the culty environments than the blatantly restrictive ones.
IJs and some EJs in general like order, so they may buck less against conservative communities than their P counterparts.
I can see this, actually. The only reason my ENTJ mom does not get along with the family is because while they are generally very decisive, business owners, professional, etc, and each agree that the other is very good at their own thing, they do not share the same visions / core values.
I can see them having many disagreements and not working as optimally as usually would, say if they were in the same company and equal positions.
