I’d answer this by saying it is human nature.

I would actually disagree with that statement to some degree. I think it is largely learned behavior to follow in the context of modern society. We spend 15+ years of our life having to follow authority in some way via the school system and that conditions us to follow more than lead on a society wide scale.

There is certainly an element of nature to via mirroring. Mirroring is when people subconsciously imitates the gestures and body language of another person to help build trust. However, I believe that our cultures way of nurturing obedience via its institutions is a bigger factor in how we treat leaders.
