Is the birth order affect a person’s I. Q.? Recently this has become a hot discussion topic after another study was published in Science (Jun. 22, 2007).

Well, whether you agree or not, you can take this birth order quiz to see if you can identify the birth orders of these famous people. The quiz is accompany to the article, “I Am Worm, Hear Me Roar” by Benedict Carey of New York Times (Jul. 12, 007).
