I was just amused because the first few minutes (I didn't watch the full 8+ minutes) were totally off, at least for me. For example, when I lived alone, my apartment was sparse... All I had was my small sofa, a bed, a pub table in the kitchen and my bookshelves and books. Now that I live with my ENFP bf-- it's a different story. All the decor is his. Literally walls covered in paintings and photography and tribal masks... Tapestries on the ceilings and enormous potted vines that he strings along the ceiling-- spanning through the dining room and living room. Not my doing, but I've accepted and gotten used to it.. Though when the house needs tidying it can feel like we are living in a flea market LOL.
If you are going to talk about cognitive functions, you have to take into account that according to that theory, each type goes through different phases of development-- which means more variation..which makes it more complicated to say this external behavior is always characteristic of X type. ( I'm not a fan of blanket statements. But to help you out, perhaps that is one discriminating factor between infps and infjs?)
Anyway, for example, when I was younger the world was a much more sentimental and emotional place for me--- and EVERYTHING was loaded with feeling and symbolism and meaning-- there was a moral to be extracted from everything. I looked at all things through an Fi lens.
I don't operate so much that way anymore now that I'm going through the Ne-Te development phase. I've literally never been more organized and analytical in my life. I've never been more emperical or linear in my thinking than in my mid-later twenties.
when I sit down with a client now, I'm not focused on their feelings and philosophies and spiritual journey. That stuff is important,and I appreciate and value that info when it is shared, but u am primarily focused on what they want to do, if they are capable of doing it, and what plan and steps I need to come up with to make it happen.
