In more prosperous societies, are men and women more similar?

Kåre Hedebrant and Agneta Herlitz in Psyche:

When it comes to gender equality, no society is perfect, but some are widely understood to have come further than others. These societies do a better job of offering equal opportunities, rights and responsibilities, and minimising structural power differences between men and women. One might expect that men and women in these societies would also become more similar to each other in terms of personality and other psychological qualities. Research has previously found differences in men’s and women’s average levels of characteristics such as self-esteem and sensation-seeking (both typically higher in men), emotional perceptiveness (higher in women), and some cognitive dimensions (though not overall cognitive ability). Do these differences become less pronounced when women and men are more equally empowered?

Surprisingly, researchers have sometimes found the opposite to be true: that improved living conditions, including greater gender equality, are associated with larger psychological differences between men and women. This phenomenon is often referred to as the ‘gender-equality paradox’.
