Oh no, what I mean by that was that if there's no way to determine what your type is, that is, if there's no way to test to see what your type actually is, then there's no point in having MBTI and its descriptors.
Sort of like the egg and the chicken concept- you need the tests to know your type.
I'm not saying you can't know what your type is - I'm referring to the kinds of quizzes that are purported to be able to determine type. It's certainly possible to determine it though,
For example Pod'lair has developed methodology for it, although it is to be noted that they disagree with calling what they do "typing" (although I disagree with their disagreement, as to me, Mojo is a means of classifying individuals based on their psychology, which is almost precisely how personality typology is defined).
Many other people claim to be able to determine type, and I believe that the method I have created (or rather, I have the general idea, and I am figuring out how to implement it) is suitable for text-based typings.
So, by applying my method, or rather attempting to, you seem to fit as an INTP, as I see you make judgements initially in posts, followed by perception oriented sentences. My method is almost certainly valid, but difficult to use, and requires much interpretation. From a brief survey of your posts, the Ti-Ne-Si order seems to fit, however I saw little in the way of Fe (which could mean that it is yet to develop to a usable level, something which tends to occur in early adulthood from my understanding, or that you simply don't include it for one reason or another).
