I think a lot of hot chicks fall victim to the Paradox of Choice. Where because they are so hot, they feel they can lure and deserve the best man possible. I'm theorizing, but they probably turn a lot of good guys down for dates, holding out for that one guy that checks all their boxes---because they "think" they can afford to.
BUT, the Paradox of Choice can be a real b*itch slap because you're never really satisfied with what you have or choose as there always "might be something better."
So I think hot chicks may have a stronger tendency to hold out for the 1/1,000,000 guy but often end up with nothing or they may reach a point of panic (maybe age 35'ish) and latch on to Mr. Beta Provider, a solid 6.5 himself, just for security. Then you see her out somewhere with the average vanilla 6.5 guy and you're like, "How the f*uck does that happen??" I see it all the time.
