Virginia, I've been ignoring that study, but without having read it, let me just point out something that we should all keep in mind: any time you see a news story about a study that proves something about human behavior, especially sexual behavior, and most especially a study that purports to prove some link between modern behavior or stereotypes and evolutionary biology, do not trust it. Reporters are notorious for taking what a scientist says and exaggerating and simplifying it until it means something completely different. Surprisingly often they take the actual result of a study and write a news story with a headline proclaiming that "science has proven" the opposite of what the researchers actually found.

Without having read it, I'm going to go ahead and predict that it's not as clear-cut as the headline suggests. You've already pointed out that it defies common sense and your own experience. It's not impossible that they found a result that contradicts both those things . . . but combine that with the fact that a news reporter wrote a sensational headline about it, and I'm suspicious.
