Is there a correlation between OCD and intelligence? Are people with OCD more intelligent than people without it? After all, people with OCD, have lots of mental activity, and generally dumb people don't. Genius borders insanity, so one could say those with OCD are geniuses especially those with the subset of OCD known as scruplosity. It takes a true genius to logically deduce how every action and thought pertains to one's morals beliefs. Some accuse those with OCD as weaving intricate webs, and would that not be the hallmark of genius?
