TED-Ed: Do IQ tests actually measure intelligence?

The video explores the history and development of IQ tests, starting with Binet and Simon's work in 1905. It discusses the misuse of IQ tests in the context of eugenics and racial bias, particularly during World War I. The video highlights the ethical and policy implications, including forced sterilizations and the influence of eugenics. It also covers the Flynn effect, showing environmental impacts on IQ scores. Modern uses and criticisms of IQ tests are discussed, emphasizing that while they measure reasoning skills, they do not capture a person's full potential.
