Does IQ Test Really Measure Intelligence?
Single tests that measure intelligence quotient, or IQ, may become a thing of the past.
A new study of more than 100,000 participants suggests that there may be at least three distinct components of intelligence. So you could not give a single, unified score for all of them.
Researchers' understanding of the complexities of the human
brain has evolved, and so too has the notion of IQ, what it really means, and how it is most accurately captured.
“There are multiple types of intelligence,” says researcher Adam Hampshire, PhD. He is a
psychologist at the
Brain and Mind Institute Natural Sciences Centre in London, Ontario, Canada. “It is time to move on to using a more comprehensive set of tests that can measure separate scores for each type of intelligence.”

IQ tests 'do not reflect intelligence'
IQ tests are misleading because they do not accurately reflect intelligence, according to a study which found that a minimum of three different exams are needed to measure someone's brainpower.

What Does IQ Really Measure?
Kids who score higher on IQ tests will, on average, go on to do better in conventional measures of success in life: academic achievement, economic success, even greater health, and longevity. Is that because they are more intelligent? Not necessarily. New research concludes that IQ scores are partly a measure of how motivated a child is to do well on the test. And harnessing that motivation might be as important to later success as so-called native intelligence.
Researchers have long debated what IQ tests actually measure, and whether average differences in IQ scores--such as those between different ethnic groups--reflect differences in intelligence, social and economic factors, or both. The debate moved heavily into the public arena with the 1994 publication of
The Bell Curve by Richard Herrnstein and Charles Murray, which suggested that the lower average IQ scores of some ethnic groups, such as African-Americans and Hispanics, were due in large part to genetic differences between them and Caucasian groups. That view has been challenged by many scientists. For example, in his 2009 book "Intelligence and How to Get It," Richard Nisbett, a psychologist at the University of Michigan, Ann Arbor, argued that differences in IQ scores largely disappear when researchers control for social and economic factors.
New work, led by Angela Lee Duckworth, a psychologist at the University of Pennsylvania, and reported online today in the
Proceedings of the National Academy of Sciences explores the effect of motivation on how well people perform on IQ tests. While subjects taking such tests are usually instructed to try as hard as they can, previous research has shown that not everyone makes the maximum effort. A number of studies have found that subjects who are promised monetary rewards for doing well on IQ and other cognitive tests score significantly higher.
