One of the reasons I like reading Vox is because he puts my thoughts into words. Another reason is that sometimes he puts into words thoughts that I might have had, had I actually taken the time to think about it. The social-sexual hierarchy is one of those thoughts that I didn't have but after reading about it, makes sense to me.
When you've got a list of categories you want to see where you, and others fit into it. I saw that going on when he introduced the concept of Sigma. It seemed like several fellas wanted to paint themselves into that picture.
You almost have to go back to Jr High and High school to come up with a universally recognizable picture of a sigma. Here's my attempt at a description. A sigma is the guy that:
Is in the chess club, or drama, band, etc
Is into typical guy stuff,
Doesn't care who knows that he likes poetry, or classical music etc.
Hates school/the system.
Loves to read,
Can't be bothered to apply himself.
Will fight black kids
Be friends with the biggest black guy in school
Take out the sister of one of the guys he fought.
Likes having fun, especially when it means taking risks.
Will go to a party at an unpopular kids house because he wants to, even if the rest of the class blows it off.
Will ask out the hottest girl in school
Get turned down,
Show up with another date that turns heads.
When his date is asked where she goes to school, she will say "I'm a sophomore at State", because she is.
He will care deeply
Say it doesn't matter
No one will know which is true.
At 17 his date will get carded at the bar
He will not
She is 21 and the doorman assumes he is too.
The sigma will drink a beer with the stoners, the jocks, the band geeks, the brothers or his first period teacher because that's who he wants to have a beer with.
He will date a dumb girl and the class Valedictorian, on the same night.
He will not go along to get along.
He will not snitch.
The sigma is a guy who doesn't fit "in" because he isn't exclusively "in" any group, but he isn't excluded because he's basically cool with everybody. He's the guy that likes what he likes and does what he wants to do. Girls go along with it.
