Are there universities that cater specifically to shy people?

Are there universities that cater specifically to shy or reserved people? It seems like many universities have the usual social hierarchy set up of 'popular' student , 'overachievers' , 'sports-inclined' , 'outcasts' or 'rebels' and the very reserved who might also fit into 'outcasts'. Unfortunately nothing seems to be done about this academic social-caste system which is in regular schools and university. Though I'm primarily concerned about the socially reserved students. As young minds are very vulnerable to emotional instability it would be great if reserved students had a special university or at least a special part of a university where they could learn freely without worrying about the problems of socializing. Are there such universities that can be a haven for reserved students?
