Not sure what that means? Or how to explain that contradiction? Here's a primer.
(Okay, apparently this has been around for a while, but I just learned about it via @sivers.)
Particularly comical bits and pieces:
Extroverts are easy for introverts to understand, because extroverts spend so much of their time working out who they are in voluble, and frequently inescapable, interaction with other people. They are as inscrutable as puppy dogs. But the street does not run both ways. Extroverts have little or no grasp of introversion. They assume that company, especially their own, is always welcome. They cannot imagine why someone would need to be alone; indeed, they often take umbrage at the suggestion. [...]
Are introverts oppressed? I would have to say so. For one thing, extroverts are overrepresented in politics, a profession in which only the garrulous are really comfortable. Look at George W. Bush. Look at Bill Clinton. They seem to come fully to life only around other people. To think of the few introverts who did rise to the top in politics—Calvin Coolidge, Richard Nixon—is merely to drive home the point. With the possible exception of Ronald Reagan, whose fabled aloofness and privateness were probably signs of a deep introverted streak (many actors, I've read, are introverts, and many introverts, when socializing, feel like actors), introverts are not considered "naturals" in politics.
Extroverts therefore dominate public life. This is a pity. If we introverts ran the world, it would no doubt be a calmer, saner, more peaceful sort of place. [...]
With their endless appetite for talk and attention, extroverts also dominate social life, so they tend to set expectations. In our extrovertist society, being outgoing is considered normal and therefore desirable, a mark of happiness, confidence, leadership. Extroverts are seen as bighearted, vibrant, warm, empathic. "People person" is a compliment. Introverts are described with words like "guarded," "loner," "reserved," "taciturn," "self-contained," "private"—narrow, ungenerous words, words that suggest emotional parsimony and smallness of personality. Female introverts, I suspect, must suffer especially. In certain circles, particularly in the Midwest, a man can still sometimes get away with being what they used to call a strong and silent type; introverted women, lacking that alternative, are even more likely than men to be perceived as timid, withdrawn, haughty.
[...] We [introverts] tend to think before talking, whereas extroverts tend to think by talking, which is why their meetings never last less than six hours. "Introverts," writes a perceptive fellow named Thomas P. Crouser, in an online review of a recent book called Why Should Extroverts Make All the Money? (I'm not making that up, either), "are driven to distraction by the semi-internal dialogue extroverts tend to conduct. Introverts don't outwardly complain, instead roll their eyes and silently curse the darkness." Just so.
Personality is a hilarious thing...
