It is but it also Depends. In some cases intelligence can be a detriment to the relationship based on the person's personality.
I've dated many so called "educated" smart women in my lifetime
- 3 lawyers
- 4 Engineers (mostly those i went to school and worked with)
- 1 accountant
Some are cool and some let their degrees go to their heads. I cant blame them because we all need our defense mechanism.

But some women tend to over-think every situation to the point where their intelligence becomes the biggest reason why they are alone and miserable. My biggest example is this chick i know who is a writer. I really wish i had the time to explain this one but she's such a mess I cant do this during the work day. Maybe later
