I'm sure I'm just stealing this point from someone else, but just in case I'm not:
People have this view that the notion of someone being able to manipulate the physical world with his or her mind is patently absurd. If there were reported cases of someone with "telekinetic" powers, the scientific person would try to come up with a "rational" explanation, because obviously you can't just will a rock off the ground. And yet, all the time we just will our own bodies off the ground. Nobody would think much of it if I exclaimed, "Holy smokes! Yesterday I saw this guy who could control his eyebrows with his mind!!"
