Somewhere between bee's comments and my own observations of other -heads, a pattern emerged in my mind...
Leading seems to have very little difficulty with its Role function, .
My question, then, is: "As introverted functions seem to behave as passive receptors, is an introvert's role inherently less taxing, while still carrying a degree of lessened sensitivity?"
Further question for thought, directed at my beloved mpletons (j/k <3): do you have a -ego parent or guardian?
