Grit(24)
A more unexpected observation was how little IQ mattered in distinguishing the most from the least accomplished. The average childhood IQ of the most eminent geniuses, whom Cox dubbed the First Ten, was 146. The average IQ of the least eminent, dubbed the Last Ten, was 143. The spread was trivial. In other words, the relationship between intelligence and eminence in Cox’s sample was exceedingly slight.

If intellectual talent wasn’t the determinant of whether a person ascended to the First Ten or was relegated to the Last Ten, then what was? While poring over thousands of pages of biographical data, Cox and her assistant also evaluated sixty-seven different personality traits for a subset of one hundred geniuses. Cox deliberately chose a rainbow of traits—in fact, she covered the full range of what modern psychologists consider to be important—to allow for the fullest possible exploration of the differences that set apart the eminent from the rest of humanity and, further, the First Ten from the Last Ten.
For most of the sixty-seven indicators, Cox found only trivial differences between the eminent and the general population. For instance, eminence had little to do with extroversion, cheerfulness, or sense of humor. And not all the high achievers had earned high marks in school. Rather, what definitively set apart the eminent from the rest of humanity were a cluster of four indicators. Notably, these also distinguished the First Ten from the Last Ten—the super-eminent from the merely eminent. Cox grouped these together and called them “persistence of motive.”
Two indicators could easily be rephrased as passion items for the Grit Scale.
Degree to which he works with distant objects in view (as opposed to living from hand to mouth). Active preparation for later life. Working toward a definite goal.
Tendency not to abandon tasks from mere changeability. Not seeking something fresh because of novelty. Not “looking for a change.”
And the other two could easily be rewritten as perseverance items for the Grit Scale.
Degree of strength of will or perseverance. Quiet determination to stick to a course once decided upon.
Tendency not to abandon tasks in the face of obstacles. Perseverance, tenacity, doggedness.
In her summary comments, Cox concluded that “high but not the highest intelligence, combined with the greatest degree of persistence, will achieve greater eminence than the highest degree of intelligence with somewhat less persistence.”

However you scored on the Grit Scale, I hope it prompted self-reflection. It’s progress just clarifying your goals, and the extent to which they are—or aren’t—aligned toward a single passion of supreme importance. It’s also progress to better understand how well you’re currently able to persevere in the face of life’s rejection slips.
It’s a start. Let’s continue, in the next chapter, to see how grit can and does change. And, then, in the rest of the book, let’s learn how to accelerate that growth.

I. If, for example, you scored 4.1, you’re grittier than about 70 percent of the adults in our sample.

GRIT GROWS
“How much of our grit is in our genes?”
I’m asked some version of this question pretty much anytime I give a talk on grit. The nature-nurture question is a very basic one. We have an intuitive sense that some things about us—like our height—are pretty much determined in the genetic lottery, while other things—like whether we speak English or French—are a result of our upbringing and experience. “You can’t train height” is a popular expression in basketball coaching, and many people who learn about grit want to know if it’s more like height or more like language.
To the question of whether we get grit from our DNA, there is a short answer and a long one. The short answer is “in part.” The long answer is, well, more complicated. In my view, the longer answer is worth our attention. Science has made huge strides in figuring out how genes, experience, and their interplay make us who we are. From what I can tell, the inherent complexity of these scientific facts has led, unfortunately, to their continually being misunderstood.
To begin, I can tell you with complete conviction that every human trait is influenced by both genes and experience.
Consider height. Height is indeed heritable: genetic differences are a big reason why some people are really tall, some really short, and a bunch of people are of varying heights in between.
But it’s also true that the average height of men and women has increased dramatically in just a few generations. For instance, military records show that the average British man was five feet five inches tall about 150 years ago, but today that average is five feet ten inches. Height gains have been even more dramatic in other countries; in the Netherlands, the average man now stands almost six foot one—a gain of more than six inches over the last 150 years. I am reminded of these dramatic generational gains in height whenever I get together with my Dutch collaborators. They bend down solicitously, but it still feels like standing in a forest of redwoods.
