Biographies of a Scientific Subject: The Intelligence Testlocked

  • Annette MülbergerAnnette MülbergerUniversity of Groningen

Summary

The intelligence test consists of a series of exercises designed to measure intelligence. Intelligence is generally understood as mental capacity that enables a person to learn at school or, more generally, to reason, to solve problems, and to adapt to new (challenging) situations. There are many types of intelligence tests depending on the kind of person (age, profession, culture, etc.) and the way intelligence is understood. Some tests are general, others are focused on evaluating language skills, others on memory, on abstract and logical thinking, or on abilities in a wide variety of areas, such as, for example, recognizing and matching implicit visual patterns. Scores may be presented as an IQ (intelligence quotient), as a mental age, or simply as a point on a scale. Intelligence tests are instrumental in ordering, ranking, and comparing individuals and groups.

The testing of intelligence started in the 19th century and became a common practice in schools and universities, psychotechnical institutions, courts, asylums, and private companies on an international level during the 20th century. It is generally assumed that the first test was designed by the French scholars A. Binet and T. Simon in 1905, but the historical link between testing and experimenting points to previous tests, such as the word association test. Testing was practiced and understood in different ways, depending not only on the time, but also on the concrete local (cultural and institutional) conditions. For example, in the United States and Brazil, testing was immediately linked to race differences and eugenic programs, while in other places, such as Spain, it was part of an attempt to detect “feebleness” and to grade students at certain schools.

Since its beginning, the intelligence test received harsh criticism and triggered massive protests. The debate went through the mass media, leading to the infamous “IQ test wars.” Thus, nowadays, psychologists are aware of the inherent danger of cultural discrimination and social marginalization, and they are more careful in the promotion of intelligence testing. In order to understand the role the intelligence test plays in today’s society, it is necessary to explore its history with the help of well-documented case studies. Such studies show how the testing practice was employed in national contexts and how it was received, used, or rejected by different social groups or professionals. Current historical research adopts a more inclusive perspective, moving away from a narrative focused on the role testing played in North-America. New work has appeared that explores how testing was taking place in different national and cultural environments, such as Russia (the former Soviet Union), India, Italy, the Netherlands, Sweden, Argentina, Chile, and many other places.
