Its effects are highly concentrated and emphasized in high school do the fact that is a fairly closed off environment with a limited population.
But it remains true outside of high school. At work, I have nothing to contribute when the lunch conversation turns to sports. Our nontechnical people often stare at me glassy eyed if I bring up recent developments in computers(and I don't even think about talking aobut the work on my masters in math). But since we all have social lives outside the office and that we are all mature adults with a real mission to focus on, we get along just fine and get the mission done. But the effect is still there, and it is easy to see how it could be magnified in a more claustrophobic environment.
I disagree that it has no meaning outside of high school. In any big city, there are still many scenes which play on the old stereotypes -- the club/bar scene, rock n roll scene, bohemian scene, gay scene, etc.
For example, if you bring up that you work with computers or have a desk job in a club, it is very noticeable that you are stereotyped as "boring" and "geeky" (at least in LA). It's all part of the popularity contest that we're familiar with from high school.
So true. Having written one book, I can refer to myself as a "writer", which is somehow more relatable. What I really need to do is learn a few chords on the guitar, come up with a name for a band, and call myself a musician. That, I think, is the only hope for a future generation of jrockways ;)
If I had to guess, it's because a lot of us here found highschool to be a highly traumatising experience, and it comforts us to know that there were others that went through that hell.
Personally speaking, it took me more than 5 years after graduating before I could even start to believe that people actually liked me. Even today I can still see little emotional tics, learned behaviours, that I developed during that period, that I actively have to work against, as they will lead me into unsuitable responses today.
It sometimes matters to think things through. If, for instance, you want to help students get better - it would do to take some time to understand the social dynamics of the world they're in.
Articles like this are potentially useful for teachers, or student counselors. Besides, even if the article's off-base, it's still helpful to search for truth, even in topics as mundane-seeming as this.
