A dumb an imbalanced N just assumes everything/ reads into everything without having any knowledge to back it up and is inaccurate half the time.
A dumb S will collect facts all day and not be able to draw conclusions about them. Accurate, but slow on the uptake.
A smart and balanced anybody should be able to do both. They will value both areas, the whole scientific process. (In even daily life decisions.) With a strength in one area or another.
