IMO a big problem many of us Ns have is what I call the "conceit of the intellectual", the notion that intellectual pursuits are more inherently worthy and important and valuable than practical pursuits. This attitude was extremely common in Graeco-Roman society, Greek and Roman intellectuals routinely belittled practical pursuits as vulgar and contaminating, which could not be further from the truth. The job of the ISFP interior decorator, or the ISTJ engineer, or ESFJ manager, can be just as mentally taxing as that of the INTJ scientist, INFP poet, or ENFJ journalist.
I am a big fan of the Spiral Dynamics model, it's a big help with getting into another person's head. No use using Green-level arguments with a Blue-level Evangelical Christian, explain things in a way that fit's that person's conceptual system.
Check out the Graves model of Spiral Dynamics. It's good stuff.
The more developed intuitives, once they hit about stage 5 in spiral dynamics, start to understand the subjectivity of big pictures. But it is a mistake to just throw that out and say "it's subjective and therefore useless or irrelevant." Instead, what you have to learn to do is match up the right big picture to the right situation.
