Enduring isolation/loneliness

I know few Beta NF and few Delta NF. I noticed that Beta NF (ILI also) can live alone, don't interact much with people for so long without feeling the need to do so and it often doesn't bother them that much. Where Delta NF would probably feel weird to be in such situation, and they need people to share what they know with (Ne I guess), but for Beta NF (and ILI) I can easily see them living in an isolated, far place, without having any problem with it.

if it's type or function related, have you noticed a similar or another pattern? And if it's Ni related, what about Alpha NT and LIE?
