Authority - Principle of Influence

I guess this principle does not need any further explaination. It is a given power the individual has to influence people.

Other than authority which allows us to use our position to exert pressure and getting things done, there is another type of power, Expert Power. It is the "knowledge" and the "know-how" in that field. So if someone claims to have that expertise, they command the authority over the rest.

However, there are some people who love to blow their own trumpet, so remember to ask yourself if he is truly the expert before we follow or be influence by him blindly.
