Does IQ really measure intelligence?

In discussion a few weeks ago, our class held a sort of debate about whether or not we think that someone's IQ will determine if they will be good for certain jobs. This has been a standing debate in psychology for many years. There are a ton of news articles out there that either agree or disagree with the use of an IQ test. For example, this article talks about how a new study shows that high IQ in childhood may actually lead to later drug use. The article does not explain why this may be true, but just that it has shown correlation in some research tests. This forces me to question the validity of this specific article, but there are still many other articles out there that talk about bizarre IQ correlations.

Based on what our group discussed, I believe both sides of the argument have some truth to them. For example, IQ fails to score creativity, which is essential for some jobs. On the other hand, high IQs have shown to positively correlate with work performance (Lilienfeld et al. 333). Depending on the job and situation, IQ may prove to be a great measure of job performance, especially in high knowledge-demanding jobs. For occupations such as an artist or construction worker, IQ may not matter quite as much and to test IQ would be a waste of time and money.
