Ironically, the less that mothers and fathers worry about outcomes, she says, the better their children may fare in life.
Gopnik spoke with NPR's Hidden Brain about her book and her view of the flaws in modern parenting.
On the changing role of parents
For as long as we've been human, the whole village has been involved in caring for children. By the time you were ready to have children yourself, you'd had lots of practical experience in caring for children.
In the 20th century, families got smaller. People got to be more mobile and people had children at a later age. For the first time, people were having children who hadn't had much experience of caring for children but had lots of experience of going to school and working. It was kind of natural for people to think, "OK, this is like going to school and working. And if I can just find the right manual or the right secret handbook, I'm going to succeed at this task the same way that I succeeded in my classes or I succeeded at my job."
On the uniquely long childhood of humans
We sort of take it for granted that children need to be taken care of for a long time. Having that long period of childhood gave you this protected period where you could move from one village to another. And childhood gave you a chance to master that new environment. A lot of the things that seem kind of strange about children — the fact that they're simultaneously so creative, so imaginative, so exploratory and yet so bad at taking care of themselves — kind of fit that picture.
On the benefits of not instructing toddlers
[An experiment] was done by [researchers] Elizabeth Bonawitz and Laura Schulz. What they found was that if you gave a complicated toy to a 4-year-old, they find all the things that it could do. It could squeak, had a mirror, it had a light. But when the experimenter said, "This is my toy, I'm going to show you how it works," and did one thing, like squeak the squeaker, children were much less likely to explore. What they did, rationally, was squeak the squeaker — what the adult had demonstrated.
On what we can learn from robots that are built to "play"
It turns out that a very good way of getting a machine to learn is to give it an early period where it can just play. If you gave a robot a chance to just dance around, figure out what its limbs could do and then you gave it a specific job, like, 'Go and pick up this piece of cloth," the robot was more resilient.
That's a good model for the things that play can do in general. If you want someone to be flexible, to say, "OK, I didn't learn how to do this particular thing, but now can I apply what I did to something else," then play really seems to play a deep role.
On how Silicon Valley gets it
Famously, Google gives their employees a day off to do whatever they want and Pixar has playhouses as part of their environment. I think the value of that kind of playful exploration is something that people in the tech world get.
On making pancakes with her grandson
One of the great joys of life is cooking with 2- and 3-year-olds. But of course they're extremely inefficient. So when [my grandson] Augie's whipping egg whites, [we] end up having egg white fresco all over the walls, and he's doing it in a way that is not nearly as efficient as it would be for me to do it myself. But it's interesting that if you look across cultures, what caregivers often do is not give their child instructions on what to do but let them participate. So let them take on a piece like whipping the eggs.
