Anything that divides people into introverts or extroverts is humbug. It's true that some people are more introverted than others in certain situations, but as a general rule, everyone are both things.
Preferring to stay home and read a book rather than socialize at a bar is an introverted trait, but dungeon mastering (or even participating) in a role playing event is extroverted. Being unsure what to say at lunch is introverted, owning the tech meeting is extroverted.
I mean, its obviously more complicated than this, but the basic rule is that there is no such thing as an introvert, and honestly, as a manager of people with varying degrees of loudness, it's not always the loudest or most social people who are good at bargaining for a raise.
Pretending something does not exist will not make it to go away. Yes, you will hardly find pure introvert or extrovert, but you will find plenty of people not in the middle of the scale and those can be called introverts or extroverts.
It's like claiming that gays and straight people do not exist because there are no 100% gay or 100% straight people.
Yes introverts do some "extroverted" stuff, and may be even very good at that. What makes them different from extroverts is that extroverts get energised by doing that, and introverts get drained.
