Chess players: You can reclaim your
intellectual superiority. It appears that you—or at least those of you
who play the game well—are unusually smart after all.
Over the past couple of decades, a
line of research
has suggested there is little or no link between a person’s general
intelligence level and their success at the classic board game. Chess
bloggers have warily picked up on the disconnect between these findings
and the popular perception of chess players as brainiacs.
“You are
all sworn to secrecy – I mean it!”
one wrote in 2007. “If word ever gets out it will be the end of one of the few perks we chess players have.”
Well, your smart-aleck status has been reinstated. A
newly published analysis
reports that, while the evidence isn’t absolutely conclusive, it seems
clear that “chess expertise does not stand in isolation from
intelligence.”
“Several studies employing psychometric tests of
intelligence have revealed that expert chess players display
significantly higher intelligence than controls, and that their playing
strength is related to their intelligence level.”
“There are now findings that expert chess players display
above-average intelligence, that their playing strength is related to
their individual intelligence level, and that their performance in
expertise-related tasks is also a function of intelligence,” writes
University of Göttingen psychologist
Roland Grabner. His study is published—where else?—in the journal
Intelligence.
Thanks in large part to the research of psychologist
K. Anders Ericsson, and the popularization of his findings by writer
Malcolm Gladwell,
conventional wisdom regarding superior ability has shifted in recent
years. According to their school of thought, practice, practice,
practice—
10,000 hours,
to be precise—really will get you to Carnegie Hall, or the World Chess
Championship. Years of long-term focused attention, they argue, play a
larger role than innate intelligence.
“Individual differences in general cognitive abilities such as
intelligence have been frequently regarded to be entirely negligible for
expert performance,” Grabner notes. But a close examination of recent
research, he writes, disproves that notion.
“Several studies employing psychometric tests of intelligence have
revealed that expert chess players display significantly higher
intelligence than controls, and that their playing strength is related
to their intelligence level,” he writes.
While there are several studies showing that playing strength in
chess can be best predicted by the amount of time spent practicing, the
assumption that expertise is developed “independent of any influence of
cognitive potential is quite implausible,” he adds. “There is growing
data suggesting that some individuals require more, and others less,
deliberate practice to attain the same expert performance levels in
chess.”
For the non-chess player, this research is interesting in that it
informs the ongoing debate over whether expertise is essentially a
matter of practice. As Gladwell, the best-selling author,
recently wrote in the
New Yorker:
“The closer psychologists look at the careers of the gifted, the
smaller the role innate talent seems to play and the bigger the role
preparation seems to play. In cognitively demanding fields, there are no
naturals.”
Gladwell points to chess as a good example of that purported truism. But
chess blogger Arne Moll,
who has some sympathy for Gladwell’s views, notes that his argument is
undercut by his apparent confusion about the various levels of chess
expertise and accomplishment.
He criticizes Gladwell’s use of the famous
Polgar sisters
(three of whom became chess masters) as proof of the preeminence of
practice, noting that although they all went through the same rigorous
regimen, their skill levels ultimately differed significantly.
Grabner cites those same siblings as evidence of the importance of
innate intelligence. “Even a reanalysis of the famous Polgar sisters
case, which is often cited as proof that only practice matters, revealed
that despite the engagement in similarly intensive practice, the three
sisters displayed quite different trajectories of expertise development,
and attained different levels of playing strength,” he writes.
In addition, Grabner adds, “comparing experts with notices of
different intelligence levels, it has been found that both expertise and
intelligence impact on the performance in expertise-related tasks.
These studies suggest that expert chess play does not stand in isolation
from intelligence.”
So it appears that (a) expertise is the result of a combination of
innate ability and hard work, and (b) chess masters have a lot going for
them intellectually. Some cliches, it turns out, are true.
