An in-depth look at IQ scores
A recent CNN article gave an exhaustive view of Intelligence Quotient, or IQ, examining what it is, what it isn’t and how it changes.
IQ is the quantified representation of a person’s intelligence.
An IQ score is derived from combining the results of several tests which measure a person’s abilities of reasoning, problem-solving, spatiality, mathematics and language.
The average score on an IQ test is 100, with large positive or negative variations indicating abnormalities.
“Anybody with very high IQ, they have the ability to manipulate, process and interpret information at a deeper level and a higher speed than the average person,” said Lisa Van Gemert, gifted youth specialist for Mensa International, in the CNN article. Mensa is an international high IQ society.
But a high IQ score doesn’t necessitate genius.
Other factors, such as emotional intelligence and practical intelligence, are not calculated by an IQ test.
Another problem with IQ testing, Van Gemert argues, is that it only provides insight into particulars, like when the test was taken, what test it was and who administered the test.
“The difficulty with these kinds of tests is that they’re a snapshot,” Van Gemert said in the article. “We see what the kid looks like on this day, on this particular test, with this particular tester.”
In the article, CNN reports that IQ scores have increased as time has progressed.
The reason for this is that greater numbers of people have been introduced to higher education, which often relies on theoretical thinking. This is known as the Flynn Effect.
“The cars that people drove in 1900 have altered because the roads are better and because of technology,” moral philosopher James Flynn said in a TED Talk last year. “And our minds have altered, too. We’ve gone from people who confronted a concrete world and analyzed that world primarily in terms of how much it would benefit them to people who confront a very complex world.”
