Experts Say Genes, Not Practice Make for Greatness

Experts Say Genes, Not Practice Make for GreatnessIs it nature (genetics) or nurture (the environment) that makes someone great in academics, sports or arts? Are experts born or made?

The question has been debated for centuries. Some contemporary authors have advocated that given a certain level of intelligence and a bit of luck, virtually anybody can get to Carnegie Hall — provided they practice, practice, practice.

In a new paper in Current Directions in Psychological Science, psychologists Dr. David Z. Hambrick of Michigan State University and Dr. Elizabeth J. Meinz of Southern Illinois University-Edwardsville disagree strongly.

“We don’t deny the importance of the knowledge and skill that accrue through practice,” said Hambrick.

“But, we think that for certain types of tasks, basic abilities and capacities — ones that are general, stable across time, and substantially heritable — play an important role in skilled performance. “

These capabilities are the bedrock of talent, Hambrick and Meinz said.

The researchers studied working memory capacity, the ability to store and process information at the same time, which correlates with success in many cognitive tasks, from abstract reasoning to language learning.

Many believe working memory is a major component for intellectual capacity.

In one experiment Hambrick and Meinz tested 57 pianists with a wide range of deliberate practice under their belts, from 260 to more than 31,000 hours, to see how well they did on sight-reading—playing a piece from a score they’d never seen before.

Practice did make a difference as those who had practiced more did better. In fact, practice—even specific sight-reading practice—predicted nearly half of the differences in performance across the subjects.

But working memory capacity still had a statistically significant impact on performance. In other words, regardless of amount of deliberate practice, working memory capacity still mattered for success in the task.

The psychologists believe that the capacity influences how many notes a player can look ahead as she plays, an important factor in sight-reading.

The authors also take an opposing view to another notion associated with the “experts-are-made” contention—that beyond a certain threshold, intelligence makes less and less of a difference in accomplishment.

Hambrick and Meinz believe their perspective is supported by a Vanderbilt University studied that looked at the math SAT scores of people with Ph.D.s in science, technology, engineering, or math.

Those who scored in the 99.9th percentile at age 13 were 18 times more likely to go on to earn a Ph.D. than those who scored better than only 99.1 percent of their teenage peers.

“Even at the highest end, the higher the intellectual ability—and by extension, the higher the working memory capacity—the better,” says Hambrick.

“Some would consider this bad news. We’d all like to think that basic capacities and abilities are irrelevant—it’s the egalitarian view of expertise,” Hambrick says.

“We’re not saying that limitations can’t be overcome.” Still, no matter how hard you work, it may be what you’re born with or develop very early in life that “distinguishes the best from the rest.”
