> more egalitarian (free and fair) a country is, the higher the differences between the gender interests?

this by itself is a contradiction. what makes a country egalitarian? how can you say a country is egalitarian and then say that some interests are not equally shared by men and women. in these countries women barely had voting rights 100 years ago but now they are called "egalitarian". maybe let's wait a generation or 2 more before concluding women biologically don't like math.

it's not even worth debating this pseudoscience. jordan is a quack. I imagine only sexists follow him because his idiotic but articulated explanations fit their view.
