Title: Why do we divide into groups?
Post by: ConfusedHermit on 17/06/2013 17:16:01
I often think that divisive terms are our worst enemy; that we should all be settled with the term 'human' above all specifications that make us create mental walls from one another. Such as race, gender, sexual orientation, etc. I think those specifications are useless when the bottom line is that we are all human.

So I imagined in my head something like a 'human pride parade' and my cynicism still led me to thinking 'Nope, there would STILL be dividing/group-separating thoughts in the human brain if an event like this ever happened.'


I just have a few questions:

1.) Why do we divide into groups (even amongst the most similar of us)? It seems all it has ever caused is war and inequality. And forgetting that we're all humans behind these online usernames.

2.) Is this as young as civilization (because societies always seem to have to put people into classes which probably just leads to even more specific sub-groups), or is this something old enough to be permanently embedded in us?

3.) Does this happen in the non-human kingdom? Is it more similar or different to the way we've done it?


Okay, I lied; one more question: While I doubt humans will last that much longer--If there exists a 'closed-minded/divisive/grouping' gene, would humans eventually breed this out and gradually divide into groups less over time? Will we ever, at our genetic core, see the furthest-from-the-majority description of a person as 'just another human like you or me?'

Or is that only likely when we're 100% mixed in race and one big global super-country? :{o~

There is a genetic explanation ...

Perhaps we can see a sequence of events similar to the following:
So how can we start to overcome this?
...and that brings us to the next level of human grouping: The species - My species is so important that every other species is worthless.

... Perhaps in 20 years we may start to overcome the implicit assumption that "my kids genes are inherently better than your kids genes"

Not necessarily "better" , it's just that there is natural-selection (http://en.wikipedia.org/wiki/Natural_selection) for the gene survival-machine (http://en.wikipedia.org/wiki/The_Selfish_Gene#Genes_and_selection) that is you to give preferential treatment to those who also carry your genes.


...  allowing genetic surgery to overcome some of the more severe genetic problems?

You'll have to genetically-engineer the instinct for kin-selection out of the genome to remove nepotism.

In the 1950s, a experiment was done, which would probably be questionable today. Two groups of boys (age ten) at a "camp" were actually being studied by social biologists, without knowledge or consent of the boys or parents. At first the two groups were kept separate. Interfering as little as possible, researchers studied how they coalesced into a group with a name ("The Eagles" or the "Rattlers") and a flag, with preferred songs, jokes, slang, rules etc. During the second week, they allowed the two groups to become aware of one another, and studied the ensuing competition and hostility, which resulted in raids on each others camps, mass brawls and flag burning.
