What is an intelligence quotient (IQ)? Intelligence is a theoretical construct with many definitions. The definition is further complicated by the belief of many that there are multiple types of intelligence. The IQ forms the most common operational definition as a cognitive and behavioral measure of global intellectual capability. Like intelligence, the IQ is best viewed as a multifaceted construct, but one that can be quantified by summing scores across tasks or subtests that comprise an intelligence test. In this way, the IQ is traditionally considered an index of Spearman's g, a general ability factor reflecting that how a person performs one task is likely similar to how well they score on others.
