I think the reason that girls are attracted to him is bcause, he doesn't seem perfect like other characters from other shows do. I find his facial imperfections humanizing in some ways. Like his slightly crooked chin and his thin nose make him seem lebih normal. Then we have his social graces. He can barely talk to people, and any girls he talks to just thinks he is a creeper. Those social flaws seem endearing and silly. And finally,we have his scientific mind. The main reason why men don't seem to like him as much is because they think he is a nerd. But women think that smart men are wonderful. Some women wish their husbands were jsut as smart as Dr. Reid. So, There is my theroy on why girls are so attracted to Dr. Reid.
