It does because the site is a right wing think tank but I will give that my link is more about "women are happier when they get to be people first" and it doesn't contradict the "women often marry up in income." The problem with starting with a place like a right wing think tank's evaluation of a study is that the goal is to sell a narrative that aligns with their existing bias. See the use of the word "prefer" which is only used once in the interview and it's from a leading question that asserts the preference to be true. It's easy for women to marry up economically: find a man doing your same job, marry him and he'll likely get paid more.

Additionally, it's easy for better educated women to do that same. Find qualified women in various industries and review the educational qualifications of their male peers who are making more than them and... same outcome.

So yes, I find the source to be problematic. I have not read the cited study itself but I did see that fun Q&A.
