Quote:

Further to that, the alpha-beta dualism has been popularly extended to include other categories such as the so-called sigma... and, yes, there are parallels in chimp troops.

The 'strong, silent, independent personality type is popularly categorised as a sigma.

In chimp troops, again as de Waal has documented, there exist chimps who appear to demonstrate all the traits of an alpha and yet do not participate in climbing the social hierarchy. They nevertheless remain within their troop and contribute to its well-being.

Another feature of chimp troops, now well documented, is when two alphas arise, each with their own coconspirator hierarchies.

When rivalry becomes too great, the troop can even split and form two separate groups, which, as in human societies, can create animosities and cause 'wars' between the two territorially abutting troops that can last generations.

I can adhere to the Alpha & Beta 'duality'.
But when you clowns start the psychobabble of Sigmas, Deltas, Omegas, etc. Well that's just pure TAROT Carding, ASTROLOGY rubbish for a gullible market. 

Think about it dickheads. There is only x8 habitable Regions and if each one had a representation of a type of 'masculinity' with x4 divided into Alpha types and the other x4 into Beta types (to EQUALISE). Then you can kiss your Sigmas, Thetas and all the rest of the Greek alphabet SOUP, goodbye as pure psychobabble trying to make something SIMPLE more complex than it really is just to appear more sophisticated than it really is for those who use it to make a buck like a fortune teller.

Alpha is those (women included) who are the Takers of the Future.
Beta is those who are Keepers of the Past.

Aborigine women are the (dare I say black) Alpha here, representatives. The Beta males are more inclined to keep to the Past (sometimes bitterly) and all things 'traditional'. Hence why Aborigines women are more likely to adopt new change for their people.
It goes with Industries to.
Alpha Politics and Beta Politics around the world.

But that's another story for later. Some regions are Alpha political, others are Beta.

Beta Males and Alpha Females on one side.
Alpha Males and Beta Females on the other.
There is no superiority or inferiority. Just purpose.

*Schlap!

Beta Males: Gays, Rednecks, Yobbos & Wankers.
...the four masculinities dominated by Alpha females.

Alpha Males: Celibates, Family Men, Business Men, Romantics
...who dominate the Beta females
