Is One Foot Really Smarter Than the Other?

This interesting exercise -- measuring how smart you right foot really is -- has been passed around the Internet for quite some time, but there's evidence it does work. Here are the steps:

  1. In a sitting position, lift your right foot off the floor and, then, make clockwise circles with it.
  2. While making circles, draw the number 6 in the air with your right hand.
  3. If the trick works as described for you, the direction of your foot will change involuntarily.

Can you "train" your foot to prevent it from moving in a different direction than the one you consciously intended? Evidently, this test was demanding enough to be shown on the Discovery channel.
