I took a year of sociology in college. One bit of wisdom that out professor gave us was how arranged marriages happen in countries where there is immense pressure to conform to traditional gender roles. He literally described these societies as hammering a person through a form to get the requisite shape the society wanted. In societies like that, you can pair up any two people and it will likely work because both know precisely what is expected of them, and there is immense pressure again to make it work, no matter what.
