The idea that men are naturally polygamorous and women are naturally hypergamous is a stereotype that has been widely discredited by social scientists and evolutionary biologists.
Humans are highly complex and individualistic beings, and it is not accurate or productive to make sweeping generalizations about the entire gender. Both men and women have the capacity for a wide range of behaviors and tendencies, and these can be influenced by a multitude of factors such as cultural norms, upbringing, personal experiences, and individual personality.
There is no scientific evidence to support the claim that either men or women have a universal and innate drive towards polygamy or hypergamy. Furthermore, these stereotypes can be harmful, as they perpetuate harmful gender biases and reinforce inaccurate and unfair stereotypes about men and women.
