Episode Details

Every parent secretly wonders if their baby is exceptional. But the signs parenting blogs swear by—early talking, intense focus, flashcard "reading," and impressive memory—have almost zero correlation with later intellectual achievement. Drawing on major longitudinal studies from the University of Oslo, the Dunedin study, and a landmark 2025 Nature Human Behaviour paper, we break down what parents are actually seeing (motor control, temperament, operant conditioning) versus the three markers that weakly but robustly predict exceptional ability. If you've ever googled "signs of genius in a one-year-old" at 3 AM, this episode is for you.
