Will a person’s IQ vary with his or her level of motivation? In other words, does level of motivation affect performance on intelligence tests? In investigating this question, a recent study had two main findings. First, IQ varies with the amount of incentives offered to the IQ-test takers.

For instance, subject A had a higher IQ when she was paid $100 to take the IQ test than when she was paid $50. Secondly, IQ scores reflect both level of intelligence and level of motivation, and that both predict academic performance and life outcomes. In other words, an individual’s IQ score of 100 is three parts intelligence and one part motivation.

In applying the results to business setting, employers may want to de-emphasize the result of IQ and other intelligence tests as the results of these measures measure more than intelligence and include confounds, such as levels of motivation and interest.
