This post peaked my interest.
I'm gonna presume that's true for most of you (if not then correct me). This could explain alot of misunderstandings I have with you guys.I believe both Si users and Se users are focused on sensations, but rather than focusing on sensation possibilities (Se), Si trys to live on just a few. So the routines created by your ISTJ friend are his actions to achieve sensory perfection. Life for me gets better when I get the chance to relive great things.
You guys derive most of your ideas, opinions, attitudes and whatnot from direct experiences. I'm a Ni-dom who dances with perspectives in idea-land. When I discuss or debate I'm focused on the concept we are discussing and I am constantly looking for different angles to see it from. More simplified: Ni are more inclined to create ideas and then see how they can generally apply to real events while Si's are more inclined to in conclude ideas from specific experiences and choose ideas by the value that the experience proves they had.
This is where the talk reaches a stalemate. You ISTJs, ime, sees the perspective as impractical and is the reason why think it's impractical because you're focused on the direct experience you concluded the idea from and not the idea's own merit? Does that mean that when I say "you should look at it from another perspective" you're actually hearing "what you concluded as true/false from that specific event you experienced, was wrong!"?
So is it because you're focused on the past experience and I'm focused on the idea that this specific misunderstanding happens?
