I agree the science is hard to do, but most people who have ever encountered women don't need a scientific studies to discover things that are blatantly obvious. Generally speaking, Women are attracted to men who are above, or at least across from them in status hierachies. Men who are unfortunate enough to lose status become less attractive to many women, increasing the risk of divorce among women who are unscrupulous. Liberalism makes a virtue of ignoring things that are obvious (challenging stereotypes, breaking down stigma etc.), by pretending that they don't exist. This leads to surprises when mundane reality reasserts itself.
