The child’s environment, i.e., nurture, is also responsible for 50% of the variation among children. For Harris, however, nurture equals peer group pressures—forget about adults and teachers. She cites research showing that humans, like other primates, have been blindly designed through evolution to be group animals and learn the best behaviors to assure survival through imitation and modeling of behavior. So the developing child’s peer group and the child’s intense longing for high status in that group (play group, gang, classroom, sport, gender) decisively shape his or her adult personality and characteristic behaviors. Once away from home, children want to be like other children they know well and unlike their parents and other adults. If the parents have any influence at all, their cultural standards and important values are transmitted to their children through the influence of adult public social and community groups interacting with groups of local children.
