Yes, you refer to the Jungian basis for the Meyers Briggs classifications. I understand that pychologists and psychiatrists frown upon MB typing as unsupported by science, as opposed to the Big that they favor. Well, I have taken many tests of each, and regardless of whether anyone can point to science that supports MB, the results of the tests (INTP) speak for themselves and are consistent with the results of my Big 5 tests. The only difference is that the Big 5 tests peg me as an extrovert, which does not surprise me as I am a not shy introvert.
