i really wish this was taught with emphasis at schools, so many people think hostility is inherently the best strategy when almost universally the best thing for everyone is to just cooperate.

even in nature where one would be lead to expect extreme violence and selfishness to be the best strategy, we see that most animals most of the time just.. get along.. You even have predators and prey giving each other side eye at watering holes because everyone needs to drink and thus the optimal strategy is for water in dry areas to generally be a neutral zone.

Evolution tends to favour cooperation because it's just obviously more efficient for two creatures to share resources rather than spend energy fighting over it. Why wrestle someone for an apple when you could instead spend the energy lifting them on your shoulders so they can reach the apples on a tree?
