My approach, to be clear, isn't to figure out if socionics is "real" or not; it has certain rings of truth to it, and my approach is to conceptualize what it IS saying, rather than argue over if it is "real"
I don't tend to indulge things like "does God exist" or "is it real" or whatever, as I find it's more useful to try to formulate what it is one is looking for -- what it does and doesn't say, rather than try to make absolute statements or reality, existence, and what have you.
