In any case, on this post further down is a comment that I will reprint here becuase I like the conclusion (I bolded it for those who just want to skip ahead.)
Did you listen to last weekend's This American Life? It was a repeat, but there was a story about an experiment a psychologist did on children around the age where they're chummy with the Easter Bunny and the Tooth Fairy. The psychologist put a box in the center of the room and told the children that there was NOT a monster in the box. Then he left the room, and the children scooted away from the box. In a second experiment the psychologist told the children that a puppy was not in the box. When the psychologist left the room, the children went to look in the box.
Sounds like 1) People don't grow up 2)Scientists get their kicks by putting boxes in the middle of rooms and telling lies.
