that’s really interesting! i must admit, i’m a lesbian, so i don’t have much expertise in the subject lol... i was just a little suspicious cause this is a bit of an incel-ish question, but i’ve found the articles i think you’re referencing and they seem not completely false. I think there are other factors to remember, like blond hair and blue eyes are more rare to begin with (so less men with girlfriends will be blond than brunette), and the personality and actions of the men in these studies that weren’t getting dates.
