*grumbles* er, um, well...
unhealthy/healthy
normal/shadow
conscious/unconscious
differentiated/undifferentiated
These all seem sort of black and white to me... also what did Jesus say? the guy with no sins gets to cast the first stone? So I do agree in some sense that it isnt a good idea to start telling other people they are not using their functions "healthily". Also since we all have different scales of judgment, healthy and normal will vary pretty dramatically in definition until you hit an extreme edge of VERY unhealthy behavior.
But it does seem pretty obvious that the more you use a function, the better you are at using it. Thus likely when you do chose to deploy your dom function you are less likely to maim and kill others around you in blaze of splendid glory.
I suspect you may also be better at understanding the breakpoints and flaws of the function-you have spent a lifetime working with it, thus are very, very good at using it with precision and refinement and avoiding making mistakes. You are also very good at recognizing the more negative aspects of that function and have likely learned to tune down or compensate for those negative aspects in order to fit in with others better.
However does that mean we should all avoid using our less developed functions because we may look "unhealthy" since we dont have as much skill with them? Seems silly, as we will use those functions in one way or another. Jung said the answer was to actively recognizing when we are using them-because use them we most certainly will, unconsciously, regardless of intent.
By recognizing our own shadow, our lesser functions, we become more aware of it and learn to use it more productively and hopefully learn to use it in a less negative way. By denying our own shadow we repress it and it explodes outwards and hurts us and those around us.
Part of the diversity of humanity lies in how very different our developmental paths can be and how the environment can drastically alter the native footprint of any particular type, to to better fit the world around them, so to start defining what is normal/healthy behavior for a type or function is very presumptous. Additionally, we all fluctuate as we evolve, thus we will have these functions growing in of their own accord in peaks and valleys as we age-with the associated tough times as we learn to understand those aspects of our own minds, pretty or not, "healthy" or not, we are only human.
Also, my favorite...why should remain trapped in a predefined footprint? If part of breaking free from that mold means learning to use those other innate aspects of our personality, even if in a rough manner at first, why would one NOT attempt to do so? (This isnt rhetorical, Id actually love explanations
)
