Strength of Mind:

Quiet people have the loudest minds…

Quiet People Are Smarter/Deeper Than You.
Obviously, this one is put forth by some quiet people themselves, in a sort of overdefensive backlash against being treated like the weird, abnormal ones. History has always shown that the most sensible way to fix discrimination against one group is to turn around and discriminate against the other group instead. What’s the old saying? Two wrongs make a right? You see that kind of attitude in articles like this one, where the author talks about how introverts are “more intelligent, more reflective, more independent, more level-headed, more refined, and more sensitive than extroverts,” and how extroverts’ conversation is “98-percent-content-free talk.” Or take this blog, which suggests you “feel bad for extraverts or as I like to call them: the life-disadvantaged.” It’s normal to be kind of resentful when you’re misunderstood, and it’s normal to feel like the universe should make it up to you by giving you some kind of positive trait to make up for it. I’m not sure if I should blame comic books for the common narrative of “everyone always treated me like I was weird and different but it turns out this weirdness is actually because I have special powers that make me better than them,” but it seems like everyone wants to play that card these days. Marvel Directory The X-Men are actually not as good a metaphor for real life as you would think. The same arguments we’re always making about how this or that trait of an introvert or quiet person isn’t wrong, just different, applies in reverse to extroverts. Maybe introverts don’t understand why extroverts need to talk so much or why they need so many friends and social events, but that’s not wrong either, it’s just different. You know, like Apple products. I don’t buy that introverts are necessarily smarter, either. I’ve met a ton of quiet, introverted people that were dumb as bricks. I do think it’s a lot easier to look smart when you don’t talk as much, because of that whole kung fu master vibe, and because anything stupid you think is less likely to come out of your mouth. On the other hand, I think there’s some virtue in being willing to take risks and say things that might be wrong, as long as you’re brave enough to fess up to and correct your mistake afterward. Basically, nobody’s wrong, except for people who aren’t willing to accept the other group of people they don’t understand.

an extroverts idea of a gathering of friends

An extrovert’s intimate gathering of a few close friends. One common definition of the introvert/extrovert divide is that extroverts gain energy from being around people, whereas introverts spend energy when hanging around people.
