An excerpt from a book that describes some experiments to show how babies learn is given the headline "See How Your Baby Detects Dolts."

The experiment is pretty elaborate and involves positioning yourself, the baby and several objects in the right places, and reading it sounds like quite a bit of work. The fact that when babies randomly point into the air they are actually aiming in the direction of Washington, D.C. from wherever they are sitting should be enough of an answer.
