It was said that leadership cannot be defined but can be described. It is something that people felt before any science came to life. It is something that can be recognised in animals too. It is felt and its effects are seen rather than defined.
The supporters of this idea claim that any definition of leadership or leaders came through observation of naturally emerged leaders and describing their characteristics and why they have followers. Accordingly, leadership definitions show confusion and are varied according to the writer experience.
Trying to turn leadership into a science that can be measured or taught is valuable and adds to the management and social science. But can any definition describe all existing leaders regardless who they are, where they are from, and if they are leaders of the uncontacted tribes?
