The psychologist Jonathan Schooler demonstrated that “mind wandering” is a stepping-stone to creativity. “The mind is inherently restless,” says Schooler. “It’s always looking to attend to the most interesting thing in its environment.” If children grow up expecting that the most interesting thing in their environment is going to be on their phones, we have to teach them to give their inner worlds a chance. Indeed, in a quiet moment, all of us, child and adult, have to fight the impulse to turn first to our devices.
