It suggests that you might have a bad habbit of critical thinking (It wouldn't surprise me if you scored high on your Ti function). You can also have been mistyped by the test (Type 4). And before you ask, no, you can't figure out if you're a Type 4 or Type 5. You might read up on it now and go "Ahh, I'm Type 5, not Type 4," but a month later something in your life has changed and you'll go "Ahh, nah, I'm Type 4, not Type 5." So don't even sweat about the minor differences between Type 4 and Type 5 if you ask me. I would, however, have been surprised if you scored a 2, 7, or 8.
