Are you an introvert or an extrovert?
It's a question you've probably heard over and over again since you were a kid. If you do consider yourself an extrovert, odds are you'd say it loud and proud; conversely, if you're introverted, you've likely felt ashamed admitting it—like it's an inherently bad thing.
That's patently untrue, of course. But where does that equation of introversion and inferiority come from?
