If you're a true introvert, how often do you make assumptions about others and how does assuming affect your perception of reality?

I asked a similar question yesterday. I’m trying to pick apart the cause and effect of assumptions.

According to the Myers-Briggs personality profile, I am a true introvert.  I’ve learned to utilize extrovert ways of being over the years, and I do enjoy being around people. Yet, in order to feel recharged, I need huge amounts of alone time. Introspection, reflection, observation, and analytic thinking are things I do constantly.

Lately, I am noticing just how often I have made and relied upon assumptions in order to form and develop relationships.  In part, this has made for a rich, internal world that has not always been reality-based.  The longer I continue to allow relationships to unfold, the more my assumptions become challenged—the things I learn about the other tend to shatter the assumptions I have made and have relied upon as the basis of my perceptions.  The more this happens, the more my internal world crumbles.

I suppose what I’m really wanting to know is this:  for those of us who are true introverts, does the shattering of assumptions detroy our internal world or does it make it stronger by awakening it to reality?
