The human brain is hardwired for an “Us vs. Them” viewpoint.
I kinda wonder, is it? Asked in a non-antagonistic way. One often sees kids before they are taught to hate be generous and caring towards others. I wonder if it’s less hardwired and more ingrained in societal upbringings. Especially in the USA where binary thinking is quite profitable.
I can also see it being hardwired, however, as it would likely live adjacent to the base survival instinct.
