Idiocracy

I came across this clip from the movie Idiocracy. I had seen bits and pieces of it on cable but had missed the intro. The movie is essentially a satire about how the stupid people of the world are outbreading the intelligent ones, leading to an eventual future earth populated entirely by morons. Though the clip is hillarious, it is also scary proposition. Though I admit I have considered this possibility in the past, I haven't done any research to see if it truly has any merits. Perhaps someone can point me in the direction of any legitimate research on the topic. Anyway, I just wanted to throw it out.
