Our culture is biased against quiet and reserved people, but introverts are responsible for some of humanity's greatest achievements. - Susan Cain

I think it’s our culture,” explains Tiffany Liao, a poised Swarthmore-bound high school senior whose parents are from Taiwan. “Study, do well, don’t create waves. It’s inbred in us to be more quiet. When I was a kid and would go to my parents’ friends’ house and didn’t want to talk, I would bring a book. It was like this shield, and they would be like, ‘She’s so studious!’ And that was praise.” It’s hard to imagine other American moms and dads outside Cupertino smiling on a child who reads in public while everyone else is gathered around the barbecue. But parents schooled a generation ago in Asian countries were likely taught this quieter style as children. In many East Asian classrooms, the traditional curriculum emphasizes listening, writing, reading, and memorization. Talking is simply not a focus, and is even discouraged.

(Finland is a famously introverted nation. Finnish joke: How can you tell if a Finn likes you? He's staring at your shoes instead of his own.)

So when introverts assume the observer role, as when they write novels, or contemplate unified field theory- or fall quiet at dinner parties- they’re not demonstrating a failure or a lack of energy. They’re simply doing what they’re constitutionally suited for” (237).
