Study Finds That Smarter People Are No Wealthier
Wednesday, April 25, 2007 | CBC News
People who score higher on intelligence tests may still have
difficulty balancing their chequebooks, according to a U.S.
study that finds no link between smarts and wealth.
The study of over 7,000 Americans who have been tested
since the late 1970s and are now in their 40s found that
while higher IQ scores have led to higher income, that
income hasn't translated into greater wealth.
"Intelligence is not a factor for explaining wealth," said the
author of the study, Ohio State University research scientist
Jay Zagorsky, in a statement.
"Those with low intelligence should not believe they are
handicapped, and those with high intelligence should not
believe they have an advantage."
People with higher IQs tended to earn higher incomes, the
study found, with each point increase in IQ score associated
with $202 to $616 US more income per year, meaning the
difference in income between a person in the normal range
(100) and someone in the top two per cent of society (130) is
between $6,000 and $18,500 a year.
But the same trend did not carry over when the study looked
at wealth, which was defined as a combination of factors
including income, investments and home value minus
mortgages, credit cards and other debts.
While Zagorsky said the data don't provide an explanation
for this, he suggests high-IQ people are not saving as much
as others.
The study found an irregular relationship between
intelligence and measures of financial distress. The
percentage of people who maxed out their credit cards, for
example, rises from 7.7 per cent for those with an IQ of 75
or below to 12.1 per cent for those with an IQ of 90.
It then falls to 5.4 per cent for those with an IQ of 115
before rising to six per cent for those with an IQ higher than
125.
"Just because you're smart doesn't mean you don't get into
trouble," he said. "Among the smartest people, those with IQ
scores above 125, even six per cent of them have maxed out
their credit cards and 11 per cent occasionally miss
payments."
The study, which appears online in the journal Intelligence,
is based on data collected from 7,403 Americans who have
been participating in the National Longitudinal Survey of
Youth, a series of surveys conducted since 1979.
Survey participants were surveyed about income, wealth and
three measures of financial difficulty, such as late bill
payments, credit card debt and bankruptcy.
The IQ test used came from four tests found in the Armed
Services Vocational Aptitude Battery, a series of tests the
U.S. Department of Defence uses to judge recruits.
