The idea of intelligence and intellectual abilities underlying human behavior is neither new nor limited to the Western world. However, this elusive construct has received considerable attention in the last 100 years, particularly from psychologists but also from other disciplines and fields ranging from behavior genetics and cultural anthropology to education and business. Intelligence is essentially a “latent” trait describing a complex set of human characteristics that psychologists and others contend is useful in describing individual differences across many of human behaviors ranging from skill in solving mathematics problems to success in the workplace. Measuring such an abstract construct is a demanding task and draws from theory, research evidence, and professional practice needs. Furthermore, fully understanding intelligence necessitates a multidisciplinary perspective drawing from all fields in the social and biological sciences, and a mixed methods approach to researching intelligence, including longitudinal and cross-sectional, and correlational and experimental strategies.
