Self-Esteem
Self-esteem is not one of the Big Five personality traits, but it is an important aspect of one's personality. The degree to which a person is at peace with oneself and has an overall positive assessment of one's self worth and capabilities seem to be relevant to whether someone is viewed as a leader. Leaders with high self-esteem support their subordinates more and, when punishment is administered, they punish more effectively. It is possible that those with high self-esteem have greater levels of self-confidence and this affects their image in the eyes of their followers. Self-esteem may also explain the relationship between some physical attributes and leader emergence. For example, research shows a strong relationship between being tall and being viewed as a leader (as well as one's career success over life). It is proposed that self-esteem may be the key mechanism linking height to being viewed as a leader, because people who are taller are also found to have higher self-esteem and therefore may project greater levels of charisma as well as confidence to their followers.
