Like, if I'm unsure about my connections with people would that be a sign of sx first or last? Or if I'm insecure about my social standing, connectivity etc. That a sign for so last or first?
That makes sense. Personally this confirms to me for example that I am SP-last. I only notice SP-stuff at last moment or when its too late/I just decide to not care.Are you unsure about your social standing because you're paying a lot of attention to it and therefore can't ignore any weaknesses? Or because you don't pay enough attention to it, and you're aware of this and should maybe do something about it... later, when you have time? Likewise with personal connections.
Usually one of the above three instinct areas is dominant or obsessive for you (causes obsessive thinking and strong pursuit of that instinct or reaction or strong avoidance of the instinct because of the pain around it—in other words you have a major charge on it!) and causes great concern if it feels incomplete or unsatisfied.
One of the instincts is easier and more natural for you, and you are more naturally good at or comfortable with (considered the middle or second instinct).
One you neglect or are not interested in as much—doesn't draw you or satisfy you as much (last one or third).
