This question came to my head when I read the current sticky thread in /r/theredpill and I need to ask because, according to the terminology, natural alphas are vocal, proud and extroverts which leaves natural betas to be introverted beta bucks. Let alone that being an alpha doesn't mean that you're necessarily moral or right all the time, you're just loud and proud.

Isn't that different from being an introvert who makes sure that he knows what he's saying, thinks twice and is calculative?

Edit: Damn it, question should have been "can introverts be alpha males" but cannot edit the title. Awkward...
