It has been said that an IQ score can somewhat determine how successful you will be in life. It can determine what kind of career you will have. But, can your IQ score be altered depending on how motivated you are at the time of completion? According to a study at Penn's School of Arts and Sciences, motivation plays a key role in the outcome of IQ testing. She was trying to figure out, "when you statically control for motivation, what happens to the predictive power of the IQ test? What we found is that the predictive power goes down significantly." This study is not disregarding the fact that IQ scores do predict long term outcomes, but rather it questions whether it is completely because smart people are more successful in life or, we can predict outcomes based on the test takers motivation to do well.
Though I have never taken an IQ test, I have experienced different results based on motivation. In the past I have studied equal amounts for two different tests, but scored very differently. I always tend to do better on the tests I actually want to succeed at, rather than the tests I must take in order to pass. I have experienced that motivation produces better outcomes.
This theory forces us to take a second look at who is said to be "smart" and "stupid." If it is the case that motivation plays a key role in determining outcome, we must find new ways to motivate individuals for test taking. Low scores may be due to the fact that people just don't care, rather than the fact that they are not intelligent.
