First of all smart doesnt help your chances in getting married. If anything most guys are not looking for particularly smart girls. Besides most girls are average. Thats common sense no it wouldnt be called average otherwise. That being said, there are many smart girls that are still single. If anything, I think the smart girls have a harder time especially in Yeshivish dating where the guy is often uneducated and clueless about many things while she is way above and beyond him in most areas.
The girls that tend to go fast are the ones with easy going non intimidating natures, good conversationalists, good looks, money, good family…
A small percentage of guys are actually looking for a smart girl (count me in) because they feel that their masculinity or self esteem will not be challenged in any way by a smart or more accomplished wife.
