In a biological and social sense, is there any modern need for the alpha and female roles in society? How has the role of alpha personality types shifted in the last 50 years or so?
Just as a frame of reference I'm talking not over-the-top, pop cultural machismo or queen bee/diva caricatures. But I do notice that whenever people talk about alpha males and females it tends to be in the context of sexual conquests.
The most gender neutral definition of an alpha I can find is:
Ambitious, self-confident, competitive, opinionated, aggressive, results-driven achievers who insist on top performance from themselves and others...
In the business world...they fluctuate between healthy and unhealthy alpha tendencies: their magnetic leadership commands respect, but their aggressive tactics create resistance, resentment and revenge; people stand in awe of their competence and can-do energy, but they often hate reporting to them or being in a team with them.
