Have you taken the test yourself? Which result did you get? Have you based your belief that you are an INTj on that result?
Are you aware of the fact that, based on the definitions and understanding of the functions that the test is built upon, I am unquestionably a TiNe. And I am also unquestionably an INTP. And the INTP type is almost (but not 100 %) beyond reasonable doubt the same type as INTp in Socionics, even though an INTp in Socionics is a

,
which is not the same thing as a NiTe at CognitiveProcesses.com.
If people want to know the strenght of their
socionic functions, they
can not use the test you mention. But they might use it to get to know which
socionic type they are. If you get the result TiNe (INTP) then you are probably an INTp. If you get the result NiTe (INTJ) then you are probably an INTj.
