An Intelligence Quotient, or IQ, is a score derived from one of several standardized tests designed to assess intelligence. "IQ scores have been shown to be associated with such factors as morbidity and mortality, parental social status, and, to a substantial degree, biological parental IQ." IQ scores are used as predictors of educational achievement or special needs. Although IQ attempts to measure some notion of intelligence, it may fail to act as an accurate measure of "intelligence" in its broadest sense. IQ tests only examine particular areas embodied by the broadest notion of "intelligence," failing to account for certain areas which are also associated with "intelligence" such as creativity or emotional intelligence. Critics argue that to base a concept of intelligence on IQ test scores alone is to ignore many important aspects of mental ability. Some scientists dispute IQ entirely. Some psychologists are also persistent critics of IQ, calling it "the IQ myth."
