“I now have Grit Scale scores from thousands of American adults. My data provide a snapshot of grit across adulthood. And I've discovered a strikingly consistent pattern: grit and age go hand in hand. Sixty-somethings tend to be grittier, on average, than fifty-somethings, who are in turn grittier than forty-somethings, and so on.”
