If you approach it with the attitude that the condition determines the person, then I suppose, yes, that's true.

But that's a pretty miserable attitude to approach it with. It's much better to keep an open mind to the possibilities of life - although its the hope that kills you. I mean - if you have to think about such things, it's most accurate to say that that's the definition of having been an introvert.

Anecdotally, inside every introvert is a squeaking, flamboyant self, desiring to be its opposite. If you desire it, you've got to (kind of) already be essentially interwoven with it.
