History of IQ
The history of IQ dates back to the early 20th century when a French psychologist named Alfred Binet developed the first intelligence test in 1904. Binet’s goal was to identify children who needed extra educational support. His test consisted of a series of questions that assessed various mental abilities, such as memory, attention, and problem-solving skills.
Binet’s work laid the foundation for further developments in the field of intelligence testing. One significant contribution came from a German psychologist named William Stern in 1912. Stern introduced the concept of the Intelligence Quotient or IQ. He proposed a formula that involved comparing a person’s mental age (determined through the test) to their chronological age. The resulting ratio was multiplied by 100 to obtain the IQ score.
The IQ test gained popularity and was further refined by other psychologists, most notably Lewis Terman in the United States. Terman adapted Binet’s test, known as the Stanford-Binet Intelligence Scale, and standardized it for wider use. This revised test became one of the most widely used IQ assessments.
