Who created the first standardized IQ test?

Alfred Binet is recognized as the creator of the first standardized IQ test, known as the Binet-Simon scale, which was developed in the early 20th century in France. Binet's primary goal was to identify children who required special educational assistance, aiming to measure a child's intellectual abilities relative to their peers. The scale was designed to assess various cognitive skills, including memory, attention, and problem-solving. Binet's work laid the foundation for future intelligence testing and the concept of mental age, which plays a crucial role in how we understand an individual's intellectual capabilities. His research has significantly influenced educational psychology and the way intelligence is assessed today.
