Yeah I've been moving types into all sorts of categories at one point, greatly inspired by socionics.
The one at the very top of this thread is one I consider most meaningful in terms of my private oppinions of people/types:
I've noticed patterns like, everyone in group 4 seems to me to be incredibly sexy and easy-going, though distant.
Everyone in group 1 is booooring when I'm bored but reassuring when I'm stressed.
Group two is very comfortable to be surrounded by for extended periods of time if they're in a good mood; and kind-of boring when they're throwing an emo fit.
Group three - well I almost instinctively suck up to their ego as they're a little scary - perceived as threat more than anything.
The second grouping, by extraverted function, seems more fitting for an office environment etc - which makes sense as it focuses on extraversion.
A grouping based on introverted function:
INFP - ISFP - ENFP - ESFP for me - that is a group I would use in something like the military, a place where emotional intimacy/one-waveness/basically inner personal drive must merge with other members in order for the system to work. I sort-of wonder if it would lead to disaster if types were isolated like this (and general psychological unhealthyness) but it would certainly create some major fire before going out due to the constantly-self-confirming groupthink scenario. It would magnify each person to create one super-function - so you should have a super-Fi group, and maybe another Super-Ti group, Super-NI and Super-Si - conflict within would be minimal but conflict with the outside world would be impossible to avoid.
Or maybe I'm just going crazy with this theory
