If you wanted to figure out what really matters for raising happy, successful kids, you’d need to randomly select a bunch of babies from a broad spectrum of backgrounds. Then you’d need to follow them for decades. Only after measuring a multitude of factors about their personalities, families, schools, and neighborhoods could you tease out what mattered and what didn’t.
That sounds like a tall ask. But thanks to a team of dedicated psychologists who have been following and intimately recording the lives of more than 1,000 kids from the New Zealand town of Dunedin since 1972, we actually have such a study.
