Over-Reliance on IQ

Some authors question the existence of "the g factor" and thus hold that the result of an IQ test is meaningless, thus rendering the notion of giftedness meaningless. The most famous example is The Mismeasure of Man by Stephen Jay Gould. In her book, Identifying Gifted Children: A Practical Guide, Susan K. Johnsen (2004) argues that schools should use a variety of measures of students capability and potential when identifying gifted children. These measures may include portfolios of student work, classroom observations, achievement measures, and intelligence scores. Most educational professionals accept that no single measure can be used in isolation to accurately identify a gifted child.
