Geoffrey Miller, “The Mating Mind: How sexual choice shaped the evolution of human nature”
Apathy

Ecologists have long understood that the typical interaction between any two individuals or species is neither competition nor cooperation, but neutralism. Neutralism means apathy: the animals just ignore each other. If their paths threaten to cross, they get out of each other’s way Anything else usually takes too much energy. Being nasty has costs, and being nice has costs, and animals evolve to avoid costs whenever possible. This is why watching wild animals interact is usually like watching preoccupied commuters trying to get to work without bumping into one another, rather than watching a John Woo action film with a triple-figure body count.

Apathy is nature’s norm.
