Wikipedia says "In psychology, human intelligence is commonly assessed by IQ scores that are determined by IQ tests. However, there are critics of IQ tests who, while they do not dispute the stability of IQ test scores, or the fact that they predict certain forms of achievement rather effectively, do on the other hand argue that to base a concept of intelligence on IQ test scores alone is to ignore many important aspects of mental ability.
On the other hand, Linda S. Gottfredson (2006) has argued that the results of thousands of studies support the importance of IQ for school and job performance. She says that IQ also predicts or correlates with numerous other life outcomes. In contrast, empirical support for non-g intelligences is lacking or very poor."
