The Wall Street Journal says there’s no difference between a child whose primary interest is reading and a child who uses social media obsessively. In WSJ’s March 22–23 “Mind and Matter” column, Alison Gopnik recounts, in fable form, her childhood obsession with “The Device,” which turns out to be books. She then claims to know of research supporting the notion that reading books “hijacks” large portions of a child’s brain, portions “that had originally been designed for other purposes.”
