There is a new student on campus who doesn't know anyone yet. Why would you expect this student to ...

Answer: The new student would join groups in order to fulfill his or her need to belong, the fundamental need to maintain stable relationships with others. The student may also join groups that are related to a part of his or her identity. For instance, if the student is a musician, he or she may seek to join a band. If the student enjoys soccer, he or she may join a soccer team, or find friends to play soccer with. The students in the groups the new student would join would be homogeneous. This is because of the social norms that groups expect their members to follow.
