The way I see it that instinct is the cause behind so much suffering and injustice in the world.
No because there is no natural selection happening for that trait. But in once case aliens. If there where aliens discovered and they where hostile maybe even not I could see humans banding together as a group but it would still be an us vs them situation.
Now that’s a great question!
We do need a slightly better tool than democracy, for sure
I hope so. Knowledge and curiousity feed intelligence feed knowledge feed curiousity. A highly educated society with healthy education sytem and good working socioeconomy (concurency in news coverage) can theoretically get over “us vs. them”. Until we someday maybe lose it as evolutionary trait.
Us ve them is just a convenient cover for me me me, so I doubt it
