The number of leaders and coordination

In “Evolution of personality differences in leadership” Johnstone and Manica define leadership and the relation of conflict with the number of leaders and the challenge of coordination.

Leader is the person able to impose his/her preferences on followers and coordinate effectively.

A society has more leaders as more conflicts emerge. However, the higher the number of conflicts and leaders, the more difficult becomes coordination. The opposite is also true.
