As you may have guessed from the fact that I am blogging about it at all, it turns out it had some pretty interesting and unexpected things to say! I highly recommend the book to anyone who is an introvert, or an extrovert who knows introverts, or a parent of a quiet child, or a human being.
One of the more interesting things I learned was about the neuroscience behind temperament, and relatedly, why oral exams are a horrible way to judge knowledge and intelligence. If I could have told my examiners, "Look, I am a 'high-reactive' type of person, which means my amygdala goes into high gear in stimulating situations like being around people and trying new things, so in these situations my neocortex is spending considerable effort to soothe my amygdala, thus interfering with my ability to speak on the fly and 'think on my feet', so kindly bugger off, and anyway what does thinking on your feet have to do with being a good scientist, aren't good results obtained with careful diligence and error-catching?!".... then perhaps I could have saved myself a few years of stress and anxiety. But somehow I don't think it would have gone over too well. Luckily, giving scientific talks has none of the stress-inducing JUDGMENT of exams, and I usually eat some dark chocolate right before speaking. (To stimulate the release of dopamine, of course.)
I interpreted this part of the book as an explanation for why mantras work. Specifically, this quote:
In fact, a recent fMRI study shows that when people use self-talk to reassess upsetting situations, activity in their prefrontal cortex increases in an amount correlated with a decrease of activity in their amygdala. (p. 118)Fear is a pretty basic emotion governed by the primitive part of the brain, but we can learn to get over it by activating our powerful front brain. However, the fear response of the amygdala never goes away completely, so when the cortex is otherwise occupied, such as in stressful situations, we may find that we do not have our shit together as much as we thought we did. Shit.
"Quiet" covers the basics of introversion/extroversion for people who spend too much time at parties to learn about this fundamental aspect of human personality. (JUST KIDDING extraverts, I love you! but seriously pick up a book sometime okay?) It dispels myths about introverts, such as they are always shy and depressed - though this awesome cartoon might be the best explanation of introversion. "Quiet" also talks about related aspects of temperament like sensitivity (though 30% of sensitive types are extraverts if I remember correctly), which describes people who are "keen observers" who "have difficulty when being observed or judged", "tend to be philosophical" and "dislike small talk", and who "feel exceptionally strong emotions" and "process information about their environments unusually deeply." (p. 136) Does that sound like someone you know?
There are a bunch of other insights that could be drawn from the book, from politics to the media to religion to business to education to relationships.... basically, anything that involves people, because people are either introverts or extraverts or both. So that pretty much covers everything.
But you don't have to take my word for it! Go read it yourself! If you want to. Or you can just take my word for it. It really doesn't matter either way. Do whatever you want! Just calm down.
