Summary:
- The article discusses how humans are "hard-wired" to be tribal and form in-groups and out-groups. It explains that this is a result of our evolutionary history as social animals.
- The article suggests that this tendency towards tribalism and in-group/out-group thinking can lead to conflict, prejudice, and discrimination, even in modern society.
- However, the article also notes that our ability to cooperate and form larger social groups has been a key factor in the success of the human species, and that finding ways to harness this while mitigating the negative aspects of tribalism is an important challenge.
