In America today, you've got multitude of "us vs them" dynamics - anti-terrorist, liberal-vs-conservative, rich-vs-poor, black-vs-white, etc. And at lot of this comes because, as the article says, "us versus them" is a powerful psychological dynamic. Given that that current American society is hyper-competitive, it seems likely this situation will continue. If pulling "us versus them" is akin to chemical warfare - a…
Isn't this just the nature of reality though? A never-ending battle for resources and territory? On time lapse, even tree roots are fighting for water, and leaves are fighting for sunlight. I feel like this article might as well be called, "Overcoming Reality." Which the article basically admits, since these in-group / out-group distinctions are so deeply hardwired into our neurology.

Levels of competition within a given collection of organisms is relative - the cells of the human only occasionally compete directly - in the rebellion known as cancer (which clearly isn't the norm).
Not all societies compete at the same level but levels of competition also depend on the level of technologies and resources available. English society didn't stay in permanent civil war when muskets were introduced but you can see situations where the introduction of muskets and potatoes cause civil wars in societies where they were introduced [1].

An army facing another army can experience toxic levels of internal competition that prevents it from being effective against an enemy (or oppositely, it might experience a lack of "killer instinct" before the key moments I suppose).
