it's a neat categorized thing but I wonder if the reality is that people fall somewhere on a continuum rather than being one specific type. Sure, we all know people who seem to be very obviously this or that type. I know textbook SLEs, IEEs, SEIs and ILEs. But there are others that kind of defy the whole categorization thing. And I think it's probably because reality can't always be shoved into a category that easily. For example, my dad is SEI-Fe but quite heavy on the Fe almost to the point of being IEI. I mean, I realize that the theory says you can't be both. But I almost see him as being BOTH Ne and Se seeking. He reacts with equal enthusiasm to each! I also think there could be a person who is strong in both ego blocks, take for example Ni and Fe. But yet it's unclear whether they're NiFe or FeNi. It's not like a huge problem or anything but I'm not sure the reality is that they're one or the other. I know that's what the theory of socionics SAYS but I don't know if that's the truth. It could just be that they lead with both at different times. Trying endlessly to figure out which is the BASE function might be just a waste of time. Some people are obviously rational or irrational. With others, it's less obvious. And then subtypes come in and explain. Or people use enneagram and stackings to explain certain things. And there's who your parents are that may have affected you or your religious beliefs. I mean, when you look at people and all the factors that influence who they are, it's kind of amazing that you can discover their ego block functions at all. And maybe it's not all that important in the end.
