Taken together, the data I’ve collected on grit and age are consistent with two different stories. One story says that our grit changes as a function of the cultural era in which we grow up. The other story says that we get grittier as we get older. Both could be true, and I have a suspicion that both are, at least to an extent. Either way, this snapshot reveals that grit is not entirely fixed. Like every aspect of your psychological character, grit is more plastic than you might think.
