The notion of the Alpha, which science accepts as part of the animal world, is heavily questioned by the psychology community as researchers consider its applicability to the case of the human male.

It’s often the case that popular culture gloms onto an idea that springs from science, but when science gathers more data and moves on, popular culture is slow to catch up.
