Abstract
Leader can lead in different ways. Some are more transactional leaders others are transformational leaders. Moreover, the human being can use his brain in different manners therefore intelligence can take several forms. In this paper, I will study the different forms of intelligence and different form of leadership and the relationship between emotional intelligence and the different leadership style and leadership effectiveness. Transformational leadership style seems to bring better results than transactional leadership style.
Both intelligence and the notion of leadership are broad terms that can be understood in differents ways. According to the psychologists Schmidt and Hunter (1998, 2000), intelligence can be define as "a broad mental capacity" to understand, think, resolve complex problems, and to learn quickly. This is the general definition of intelligence, but we can be intelligent in several manners. In this paper, we will focus on emotional intelligence and transformational intelligence. Regarding leadership, the notion has been defined as "a process of social influence in which one person can enlist the aid and support of others in the accomplishment of a common task" by the social psychologist M. Chemers (1997). However, a leader do not necessarily a good job. Great leaders are those who know how to motivate the others and how take the best in them.
