6min 9sec @TEDEd clip - The dark history of #IQtests - Stefan C. Dombrowski

text from youtube "Explore the history of IQ tests; how they measure a person’s intelligence and the ways they have been used to justify scientifically baseless ideologies.
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. Lesson by Stefan C. Dombrowski, directed by Kozmonot Animation Studios. Animator's website: https://www.kozmonot.tv/
