For women, beauty is regarded a measure of their ability bear a child, and therefore considered more valuable than brain, and there is some truth to that. Women's sexual market value mostly relies on youth and beauty. Being visibly fit to bear a baby. Not education or intelligence.
However, Angelina Jolie’s and Scarlett Johansson’s of the world, have more than just physical beauty, they also have skills of acting, and even modelling requires some skill. And some luck. There are many women more beautiful than celebrities of the world, who will never be rich and famous.
And yes, for short term sex, hookups, people may look over intelligence and go for the most visually appealing ones, but for long term relationship... I'm not sure if this is a good idea.
You know, with things like make up and plastic surgery, you can make a "barbie doll" out of practically any woman. But you cannot make a stupid woman smart, nor you can make an evil narcissist of a woman a good person.
Personally, yes, beauty catches my eye first, but if all a woman has is "boobs and ass" I won't take her seriously. Maybe good for a drunk one night stand. But nothing more.
And at best, beauty fades in a few years. Women have a short shelf life.
Just look at former celebrities like Pamela Anderson.
