There isn't even anyone who pretends to be smart here. There are two or three weirdos who actually think things through, there are the smart kids who don't really care about anything but grades, and then there are the people who make this either the ghetto or hillbilly hell, which make up least 90% of the population here.
It's not that they're smart. They just pretend to be smart because it's non conformist, and non conformist is good. After all, everybody cool is doing it.
