Omar, could you elaborate more on why Ni could still be intentional despite the fact that it operates so quickly?That could sort of be said about Ne, since Ne is simply an analyzing function meant to allow a person to read and predict their surroundings.
Ne is what people stereotypically "intuitive thinking" and it does indeed lack intention a lot of the time, and Ni is what people mostly call a "gut feeling" since it is more passive unless in the hands of an experienced Ni veteran.
Ni almost never lacks intention, it is what people use to achieve what they want over time. It is meant for manipulating your situation and surroundings to imprint your internal ideal mental image onto the world.
So he's semi-right. but there are two kinds of intuition. Ni just isn't acknowledged much because almost all introverted functions are very passive and don't make themselves known externally very often.
