It turns out that a scientist can see the future by watching four-year-olds with a sweet. The researcher invites the children into a plain room. You can have this sweet right now, he says, but if you wait while I go out for a few minutes, you can have two sweets when I get back. Then he leaves.
Some children grab the treat the moment he's out of the door. Some last a few minutes before they give in, but others are determined to wait. They cover their eyes, they put their heads down, they sing to themselves, they try to play games or even fall asleep. When the researcher returns, he gives these children their sweets, and then, science waits for them to grow up.
