Humans are a tribal species. We form alliances, align ourselves along ethnic, familial, religious, and cultural lines. Still, for the vast majority of people, “tribal” carries a negative connotation. Bitter partisan politics, ethnic genocides, religious wars, and the long history of bigotry make that connotation almost unavoidable. But I don’t think tribal in its true essence is all bad. The basic instinct to form and belong to groups is a simple fact of human physiology. It’s how we work, so we’d better make it work for us.
