In 2007 in my lab at Berkeley, Tamar Kushnir and I discovered that preschoolers can use probabilities to learn how things work and that this lets them imagine new possibilities. We put a yellow block and a blue block on a machine repeatedly. The blocks were likely but not certain to make the machine light up. The yellow block made the machine light up two out of three times; the blue block made it light up only two out of six times.

Then we gave the children the blocks and asked them to light up the machine. These children, who couldn’t yet add or subtract, were more likely to put the high-probability yellow block, rather than the blue one, on the machine.

We also did the same experiment, but instead of putting the high-probability block on the machine, we held it up over the machine and the machine lit up. Children had never seen a block act this way, and at the start of the experiment, they didn’t think it could. But after seeing good evidence, they were able to imagine the peculiar possibility that blocks have remote powers. These astonishing capacities for statistical reasoning, experimental discovery and probabilistic logic allow babies to rapidly learn all about the particular objects and people surrounding them.
