This idea suggests a solution to the evolutionary paradox that is human childhood and adolescence. We humans have an exceptionally long childhood and prolonged adolescence. Why make human children so helpless for so long, and make human adults invest so much time and effort into caring for them?
The answer: Childhood and adolescence may, at least in part, be designed to resolve the tension between exploration and exploitation. Those periods of our life give us time to explore before we have to face the stern and earnest realities of grown-up life. Teenagers may no longer care all that much about how the physical world works. But they care a lot about exploring all the ways that the social world can be organized. And that may help each new generation change the world.
