In reality, the cognitive category of a tribe, in-group, or coalition is abstract and multidimensional.126 People see themselves as belonging to many overlapping tribes: their clan, hometown, native country, adopted country, religion, ethnic group, alma mater, fraternity or sorority, political party, employer, service organization, sports team, even brand of camera equipment. (If you want to see tribalism at its fiercest, check out a “Nikon vs. Canon” Internet discussion group.)
