IQ testing in my opinion is not a very good method to measure a person's intelligence. First off an IQ test is a standardized test, so therefore there must be a way for a person to improve on the test after each time they take it. If there is a way to study for the test and a way to improve then how can we say that an IQ test is true measure of intelligence? The IQ test measures common intelligence that most people would consider to be a "smart" person but the IQ test doesn't measure anything that involves social dynamics or other types of "street smarts."
The text also talks about how the SAT and ACT are closely related to a person's IQ score, but yet at the same time someone's SAT and ACT score can be raised through studying. I know when I took the SAT I had a tutor and my tutor would tell me the tricks of the SAT test and how the people who make the test try and trick you. I was able to improve my score through studying but at the same time I wasn't any smarter I just knew what to look for on the test.
If we look at the common definition of what people consider and intelligent person to be then the IQ test does test for that kind of intelligence, but intelligence covers way more than the common pop culture definition. The IQ test is nothing more than a way for people to measure who is going to be one of the smartest people in school. There is so much more to intelligence than just the basic IQ test and I think that a new test should be formed that will look test all of the aspects of someone's intelligence.
