so.. let me explain my viewpoint first. I've been thinking and come to the conclusion that types obviously don't exist as clear-cut or as idealized in theory, not just because this stuff is not objectively measurable with currently known tools that are considered to be objective in a scientific way, but also because I tend to think that the functions are rather like cognitive skills, and "usage" of a function (usage = you are currently looking at the world from one kind of viewpoint) is partially situational. Sure, we probably have some tendency that's partially inborn to prefer certain functions more, but I guess you also change slowly over time, depending on your experiences and your responses to those experiences, and thus can slowly change emphasis on preferences. And depending on what you learned to do in a certain kind of situation, your response in a specific situation may entirely differ from what your "type" would usually do. You can also develop techniques to respond to certain situations in a better way that would otherwise require your weaker skills. Thus, a normal well balanced person doesn't and shouldn't really fit under one clear-cut type at all. And then at this point the whole concept of types and duality and all that ceases to have much point. Two such people who also match on values outside the ones socionics attempts to explain, should work out together, regardless of their "type". This of course doesn't mean problems can't come up, but if they aren't too big, they can be solved.
So, my question is, why do some people here tend to take some of this theory seriously? Or maybe my impression is incorrect and nobody here actually tries to govern any part of their life based on just a theory, though when I see questions in the forum like "how to recognize my dual" etc. etc., I can't tell how serious that stuff is. I mean, it would rather limit one's viewpoint to look for a "dual" based on a theory.
I guess I just don't see the usefulness of this theory at this point and I'm asking how it helped other people in an objective way.
