In 1905, psychologists Alfred Binet and Théodore Simon designed a test for children who were struggling in school in France. Designed to determine which children required individualized attention, their method formed the basis of the modern IQ test. So how do IQ tests work, and are they a true reflection of intelligence? Stefan C. Dombrowski explores how the tests have been used throughout history. [Directed by Kozmonot Animation Studios, narrated by Addison Anderson, music by Deniz Doǧançay].

Modern IQ tests measure specific cognitive skills, not a person's full potential, amidst evolving understanding of intelligence.
