I agree with Health and Human Services Secretary Robert F. Kennedy Jr. that cellphones probably don't belong in classrooms. They are likely to distract from learning, to impede socialization, or both.
But Kennedy has a different concern. He recently told Fox & Friends that he's worried the phones will case "neurological damage to kids" and "even cancer."
The difference between Kennedy and me—well, there are many, but the key difference for our purposes today—is that I don't mistake my suspicions about cellphones, socialization, and learning loss for demonstrated scientific facts.
