What Does IQ Really Measure?
By Michael BalterApr. 25, 2011 , 3:02 PM
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.

IQ test scores are influenced by motivation (among other
characteristics).
I made slightly better than average grades in high school and the
first 2 years of college because of little or no effort. I was married
the last 2 years and only 5 grades (on the quarter system) were not As
(all history which I considered a waste of time). Of course my IQ
didn't change, my motivation did. Yet I was the only 17 year old
(AFAIK) in boot camp who was selected for OCS - motivation.
Some people are industrious enough to do their best regardless. Others
are motivated only by challenge. The IQ doesn't change but the level
of success does.
Right or wrong I think a number of blacks are encouraged to quit
school. Thus the social factor changes the level of success but not
the IQ. In my era kids who worked on farms were less likely to
succeed, generally speaking. Raising crops didn't require college prep
courses. Sounds like environment to me.
If you are constatnly given what you need very few are motivated to
succeed. That's why government welfare is an abyssmal failure.
