Was INTJ as a kid, ISTP now. 95/5 on the I and T, 55/45 on the S and P.
The switch from J to P is understandable with a one question difference in score. The scores are just to get a person close so you can narrow the scope to the composite character anyway.
Then on top of that J's usually learn that not everything must be judged and then learn to loosen up a bit. On the other hand, the free going P's need to learn, you can't leave issue open forever, judgments must be made at some point in order to finish or close the deal.
Since I vs E on a scale of 1 to 10 from a 10 question test, you confuse me with the 95/5. However, if I assume 90/10, this would indicate a severe case of introvert, requiring nearly all your time,
gaining the power to face the others of your species for a few moments a week. I am reticent to make this assumption. More likely you are 6/4 one way or the other, perhaps 7/3
The N vs the S, intuitive vs sensing is 1 - 20 score and 95/5 does make sense for you as an N.
The same with the T vs F. Thinking vs Feeling. 95/5 would match the person I sense, and also match my test score in this area.
From a far as we are on the internet, I don't see you as the INTJ scientist. Powerful people they are but usually narrow in focus as they must be to be a master in a field.
ISTP perhaps, but more, more likely the INTP from what I see from my shaded limited view. Keep in mind, the INTP will also be and ISTP with an overlay intuition process. But then never the true ISTP in physical ability with the direct wired path, brain to muscle. Like the fighter pilot with lightening quick reaction or the perfect athlete with same reaction capability. When pressed,the INxx will always take the time to fill in the unknown from the intuition process, rather than react purely on the information the senses provide, thus the reaction is quicker, hopefully correct.
There you see the training they do with the ISTP, like the fighter pilot. Train to react to the percentages from the information at hand from the senses. The INTP may fill in the missing data but then react too late, it's over. Nothing says he can't lead though, and plan to use the assets available.
Matching this bag of characters to the requirements needed to fill the slots on a project team is a hoot!
