Definitely N. As Lightleggy says, it is how we navigate the world. I also find that I relate much more easily to Ns. To be perfectly honest, I generally tend to dismiss S types, or rather, to overlook them. Nothing personal against S types. For me it is as though the human world is in black and white, and occasionally I catch little glimpses of color. These glimpses are the N types. This is particularly true for NFs. It is almost as if they radiate some sort of aura, and I am drawn to it, or they to me.
Of all the letters, I feel that this would be the most difficult to change. As the INFJ description says, we cannot not intuit.
