I think it is more than a single personality trait -- it's more like a combination of personality traits. It definitely exists in various forms, and it is not all learned. The converse is also true. There are some people who lack the personality traits required for leadership, and who probably could not be taught to become leaders, even if they desired to become one. When people say "so and so is a natural leader," what they mean is that people tend to follow them. That is, after all, the essence of leadership. How well they do at keeping people following them and how efficient they are in producing results are just a couple of the various qualities of leadership, but the essence of it is that people follow them, and want to follow them. Some people just naturally have that quality without any formal training. You can even see it in some very young children when they're among their peers, if you look.
