Bullshit. In the instance of an emergency, the guy who calms everyone else down and deals with the situation intelligently is the Alpha Male. If you have ever done any work in a group, you will soon find that someone has to be the leader.
Too many people trying to be leader at once or attempting to do their own thing leads to chaos. The one most skilled with the most leadership ability is the one who gravitates into that role.
One "pop" media example of this is the doctor on the series Lost. He is the Alpha Male because they look to him for leadership (at least as much as I have seen of the first season). To not know this takes place in ALL social circles implies lack of life experience.
