I did a degree in Psychology and one of the advanced topics in personality theory that came up when discussing the Introversion/Extroversion spectrum was the concept of 'Pseudo Introversion' and 'Pseudo Extroversion' The general crux is that there exist people who are what you might call 'biologically' introverts (or extraverts) but who have made a conscious decision that there is something that they love more than their base trait in the I/E personality dimension. Examples of pesudo-extroverts might be a very shy actor, singer or performer. Socially they'd be considered an introvert, but they love their craft so much that they pretend to be an extrovert in order to do the thing that they love. I thought it was pretty interesting.
