Another ominously looming related effect is the mismatch of our genetic markup regarding reproduction and the real costs and risks associated with reproduction in our society.
Evolutionary psychology tells us that
men care for securing a wife because they cannot be sure of their offspring—but with paternity tests they can. And risk nothing if they cheat—but a paternity test might catch them. And sex leading to offspring can be prevented now.
women need a provider to care for their offspring and risk a lot by pregnancy—but society ensures at least a minimum provision esp. for children and medicine has reduced risk by birth to a minimum.
Thus effectively the reproduction causes for gender differences are mostly eliminated in our society and this should—in the long run—lead to much more pronounced effects.
As the key factor that remains is child care and parenting I’d predict that male behavior geared toward the well-being and fostering of legitimate children is going to prevail and win over jealous and dominant behaviors.
It is difficult to tell long term genetic effects from faster effects due to incentive structures.
As this is dependent on availalability of reliable child legitimacy tests this even allows to test this hypothesis in the long run: Societies allowing this might show different male behavior.
