This is to be an example not proof, but lets talk about the pack mentality. Which is a psychologically defined personality/mindset qualification for social norms. That’s pretty heavy, so lets simplify.
TO THE WOLVES
Some people say that this mentality doesn’t exist, but I have firsthand seen too many people get primitive mindsets and almost wolf like pack mentality. Not often, but I HAVE seen it. Let’s say the President of the school government, and the head quarterback get into a fight. (could be verbal or physical). They get together and start bickering back and forth over some event in the school. Let’s say homecoming.
Even better let’s say it is over a girl, which is generally the case anyways, they are relatively professional in their own environment, playing the game with respectful manners, and leading the government with class. Despite this when they confront each other their manners start to go out the window, they get physical, they start yelling curse words, and they get simply out of hand.
CONFLICT
These two professional popular people are becoming more and more animistic. Violent maybe. This is because their simplistic parts of the brain are taking control, the pack mentality. They both are “Alpha male” personas, which in most cases got them to be where they are in their respective fields. In normal cases they may even be friends because they are so social, but when some sort of conflict created their fighting they became simple.
IT’S PSYCHOLOGICAL
Now we are getting to the point where this impacts YOU. This previous story was because of it was two people of the same “level” of status in the pack fighting. When it comes to people who are in some sort of pack, cliche, tribe, group (whatever you call it its the same). They are betas the lower ring of the group. Someone who is not the leadership type, at least at that stage in their life.
PRIMITIVE
Now despite all of this, I strongly believe we can overcome the pack mentality as a species, its unnecessary and prevents innovation/growth. We need to come together as a species and simply say that we will sort out our differences as adults, and with a calm mind. That way we can attempt to please both sides, and foster new growth from it all.
We are the future, and it is up to us to establish a strong world. We need to come together peacefully in order to survive, and yes that is akin to a tribal mentality of coming together. Despite that we can actually create an environment more advanced than any other tribe that we have established now. Really that is what it comes down to, all cities, towns, and provinces are all some sort of tribe. Being in a tribe isn't what causes the situation to be primitive, it is the mindset that comes with it. The mindset that we choose to have.
