but rather whether there are traits that women who are very successful exhibit which make them less likely to marry ceterus paribus than women who do not exhibit those traits.

I think you're on the right track. Keep in mind that their definition of "smart" women are women who have stayed in academia longer getting advanced degrees, and have had more time to get infected by campus feminist dogma

In order to have a successful relationship, there must be some degree of forsaking a little of what you want, in order to make the other person happy. Women who are not willing to do this will lose out to women who are willing

Also keep in mind that a successful man is generally willing to marry a woman who makes less than him and has less education, while the highly educated woman is not. This greatly reduces the number of possible prospects

Women with higher degrees can be nasty customers, but so can women of all educational levels. Other things being equal, I'll take a woman with high intelligence -- in this day and age, it's likelier to be a woman with a BA or higher. Smart women are much easier for smart men to talk to, much more interesting, and tend to have better values (again, other things being equal). And I say that as a guy does not believe the nonsense about looks being unimportant.
