Third, I'd like to know why you disagree with me. If you can do that without just arguing semantics, I'd like to know. If it's just semantics, then that's fine, but I don't think you should be DISAGREEING, exactly, because I didn't really make an argument, just proposed a definition. But lets see what you got.
Well...
Central Thesis: I disagree with your definition of introversion, but agree that it's unreasonable to argue the definition of shyness. IOW, I'm disagreeing that you can't define introversion such that it be right or wrong.
There IS a difinitive definition of introversion. The entire basis of MBTI is based on definite concepts with regards to cognitive functions. Introversion (as I understand it... which doesn't make it so. see what Carl Jung says) refers to the direction of focus of the function. Introverts have a dominant function that is inward-focused (Si, Ni, Fi, Ti). Extroverts have a dominant function that is outward-focused (Se, Ne, Fe, Te). That is what I was agreeing with Dissonance about:
"it's impossible to tell unless you analyze their cognitive functions and try to figure out if their dominant is introverted or extroverted."
I do not believe there is a definitive definition of shyness. It isn't a scientific term, so much as a description of a certain set of behaviors. Thus I agree completely with your second point.
I'm kind of

that you didn't read my response before responding. As punishment, I shall write a longer description of what I was saying with regards to introversion. I belive that introversion/extroversion is commonly defined by a set of behaviors/ phenotypes/ symptoms/ appearances in the same way that shyness is (probably because it's easier to understand). This is the 'introverts like to be alone, extroverts are social' definition. I believe this description is incorrect, and probably the reason you believe it's a hazy best-fit definition. As an ENFP (considered by most the most introverted appearing of the extroverts), the definition strikes me as absurd. Extroverts can be awfully nonsocial, love solitude, don't NEED human contact, etc. They are extroverts because their dominant function is directed outwards.
If you made it through this post,

. I think I brought the meats, and hope it's been spiced to your liking (metaphorically speaking... I think about 50% of my metaphors make sense). K, bye!:hi:
