I'm not sure what you mean, but I find a large difference between Ni and Ne. In a word, the difference is depth. Ni seeks a deeper understanding of whatever it is focused on whereas Ne seeks a breadth of understanding of whatever it is focused on. That difference is why Ni is known for foresight and insight and why Ne is known for innovation and creativity. I like to think of Ni as the little philosopher, always seeking a deeper understanding of the world, and Ne as the little inventor, always seeking news ways to view the world.
