There are some popular explanations for this state of affairs. The most conspicuous one is that men have deficient psyches and lack the basic capacity for monogamous connectedness, for psychological or evolutionary reasons. Their psychological, biological, and evolutionary makeup makes them prone to sexual multiplicity because masculinity is promiscuous and because evolution demands men spread their sperm, rather than care for their offspring.55 Such explanations cannot be used by sociologists, because of their tautological character, explaining a given state by simply postulating that necessity inscribed it in the genes or evolution. A different explanation for this state of affairs is that men are confused by their traditional role being challenged by the new power of women. Men withhold their commitment because they are afraid of women and their increasing power threatening their identities.
