David Berreby touches on man-kind’s need for a sense of belonging in “It Takes a Tribe”. More specifically, he takes on the sense of belonging that people invent at college. This need for association, no matter how trivial it may seem, has a large effect on the subconscious. Berreby argues that once an individual realizes that they have been placed in a union, they segregate themselves unknowingly against those not in the union. Berreby concludes that while people may not be passionate about all the groups they are placed in, the groups they identify with stay with them for life.
