Maybe it has to do with the wording of the test, it isn't inconceivable that the tests don't represent Ne vs Ni very well or Te vs Ti and there ends up being a preference bias toward N and T if you are an xNTx, without a distinction between using them as a judging or perceiving function.
The thought crosed my mind.

But I can identify with descriptions of that functions. What means that it is not just the test.
