Power is one of the biggest reasons an individual feels the need to follow through with the suggestions of another. A person who possesses more authority (or is perceived as being more powerful) than others in a group is an icon or is most "popular" within a group. This person has the most influence over others. For example, in a child's school life, people who seem to control the perceptions of the students at school are most powerful in having a social influence over other children.
