I don't know if that is actually proven. It isn't like through a lot of history women have had much choice about the whole thing, nor could they leave someone toxic in many cases. Is it an "effective life behavior" if you don't have a lot of other choices? You could use the same words to state that hetero marriage is "proven", when realistically, people didn't have the choice.
