What happens to the extremely intelligent? Do they go from success to success, powered by their natural brilliance? Or do they struggle in a world where they don’t fit in?

There are two ways to answer these questions. The first is the social science answer. Social science researchers give promising children intelligence tests, and then they check in on them over the ensuing decades to see how much the students’ early intelligence correlates with lifetime success.

I confess that I’d prefer to live in a world in which people’s lives were not powerfully shaped by some trait they happened to have inherited. But we don’t live in that world. The social science answer is that higher intelligence correlates strongly with positive educational and career outcomes.

 
 

The grandfather of these studies is Lewis Terman’s Genetic Study of Geniuses, which, starting in the 1920s, tracked 1,521 highly intelligent kids through life. By the 1950s, two-thirds of the Terman kids had become college graduates, a figure 10 times that of the general population. In 1954, the men in the Terman group who held white-collar jobs made $10,556 a year, on average. That was far higher than the $5,800 a year earned by American men in white-collar jobs overall.

More recent studies have produced similar results. For example, the Study of Mathematically Precocious Youth tracks students who scored in the top 1% of intelligence tests. This study enables us to move beyond the crude notion that there is only one thing called IQ and focus on three specific forms of intelligence: verbal, mathematical and spatial. (Spatial intelligence is the kind of object-oriented intelligence that helps you become a master carpenter, an engineer or an inventor.)

In a meta-analysis of a bunch of these more recent studies, Tarmo Strenze of the University of Tartu in Estonia found that superhigh intelligence correlates strongly with educational attainment and occupational success and moderately with higher incomes. The Center for Talented Youth is a program at Johns Hopkins for young people with very high scores on university entrance exams. Mark Zuckerberg, Sergey Brin and Lady Gaga all went through that program.

So, no surprise, intelligence really matters. These studies also show that highly intelligent people don’t suffer from more mental health problems than anybody else. They are not more likely to be scrawny.

I used to assume that there was an intelligence threshold, that once you got above an IQ score of 120, it didn’t help much if your score was over 150. But the Study of Mathematically Precocious Youth rebuts that. People who score in the top quarter of the top 1% do better than people who score in the bottom quarter of the top 1%. In other words, extraordinarily smart people do better than very smart people.

Some people want to get rid of magnet high schools and accelerated programs for these kinds of precocious kids. But these programs are necessary if we’re going to keep high-scoring students engaged and growing. I spoke with David Lubinski and Camilla Benbow, who direct the Study of Mathematically Precocious Youth at Vanderbilt University. They observed that we have inherited an industrial model school system that sometimes treats children as interchangeable widgets — every child is supposed to learn reading at age 6.

They argued that we should do more to personalize education so it’s tailored to the abilities of each child. They said we shouldn’t think of schooling as a zero-sum enterprise; we can design programs for high scorers and also ones that are inclusive for students with different profiles. They emphasized that we do a poor job of recognizing students with exceptional spatial abilities, and we should have more shop classes and other programs for those who think best with their hands.

So that’s the social science view, based on what we can learn from statistical correlations across populations of people. But there is another way to look at precocious kids that is more personal and subjective. How is life actually lived by these talented people?

When you look at the people who went through the Terman study, you find that most of them had perfectly fine lives. They were doctors, lawyers and professors. But they mostly traveled well-worn paths. If you think that intelligence is all you need, then you can’t help looking at the Terman results and asking: There aren’t as many creative geniuses as you’d expect — where are the transformational thinkers and world changers? An atmosphere of slight disappointment hangs around the study because of this.

In 1968, a researcher named Melita Oden looked at some of the Terman kids who did not go on to become professionals and worked as salesclerks or in similar jobs. She found that such people had been rated as less energetic throughout their lives, less likely to take part in extracurricular activities as students.

In 2019, Brian O. Bernstein and others looked at 677 people who were intellectually precocious when young. The researchers estimated that 12% of them had achieved eminence in their careers by age 50. But that means that 88% had not. The researchers also looked at 605 science, technology, engineering and mathematics graduate students at the nation’s top universities and found that 20% of those students had achieved eminence in their fields by age 50. But that means that 80% of these brilliant students at top graduate schools had not.

When you take a more granular, personal view of the lives of the gifted, you see that while intelligence matters, other things also matter a lot. Some brilliant people lack ambition. Some brilliant people don’t want to spend their lives at work, slaving away for eminence. They have different values and prefer to do other things with their time.

Joan Freeman is a British researcher and the author of “Gifted Lives.” For 35 years, she conducted face-to-face interviews with 210 people who had scored in the top 0.2% in intelligence. Her work didn’t yield massive data sets, but she gives us a more human picture of what being really gifted is like.

One of her subjects, Jeremy, told her: “My being seen as gifted has produced awful deficiencies in me. I was emotionally scarred by being made to perform. All the time it was, ‘Look what Jeremy can do.’ I could do almost anything on demand, but I used to feel like a performing penguin.”

Jeremy was competitive while young and felt immense pressure to demonstrate gifted achievement every day. “I could only work in fear. Only the fear of failure made me work in the end,” he said. As a young adult, he was paralyzed by the number of life options in front of him. He went into medicine and spent about 13 years as a medical student and doctor but eventually was hit by depression so severe, he couldn’t function. He wound up as a musician — not celebrated but enjoying himself and paying the bills.

When you get a glimpse of the real lives of gifted people, you see that it’s a mistake to separate this thing we call intelligence from all the other aspects of their lives. A person’s intelligence is embedded in and interacting with all that person’s other qualities — whether she is self-confident, conscientious, resilient or open to new experiences, whether she has experienced unconditional love, deep friendships, rich intellectual conversations. Just because some traits are easier to measure doesn’t mean we can isolate them and not see everything that goes into this precious and never-to-be-repeated person.

The bottom line is that we need to put intelligence in its place. We need to value it and put precocious children in settings where they are nurtured and stretched. But we don’t want to overvalue it. In my view, it’s crazy that many top universities look for students who scored over 1300 or 1400 on their SATs and reject most applicants below that. That’s placing too high a value on a narrow aspect of ability.

When you look at who really achieves great things, you notice that most of them were not prodigies. They didn’t wow people at age 18, but over the course of their adulthood they found some deep interest in something, and they achieved mastery. Many of society’s great contributors didn’t have an easily identifiable extraordinary ability; they had the right mixture of slight advantages and character traits that came together in the right way.

Yes, a child born extremely intelligent is lucky and likely to do well, but as Lubinski and Benbow mentioned in their conversation with me, we want to see each person whole. I’d put it this way: It’s nice to know who is good at taking intelligence tests, but it’s more important to know who is lit by an inner fire.
