Frecuently Asked Questions


When was the IQ test invented?

The IQ test is a widely known tool for measuring intelligence, but have you ever wondered when it was first invented? The IQ test, or intelligence quotient test, was first developed in the early 20th century, around 1905.

The credit for the development of the IQ test goes to French psychologist Alfred Binet and his colleague, Theodore Simon. They were tasked with creating a test that could identify children with learning disabilities so that they could receive specialized help in school. The test they developed consisted of a series of questions that measured a child’s cognitive abilities, including memory, attention, and problem-solving skills.

Binet and Simon’s original test was later revised and adapted by other psychologists, including Lewis Terman, who is credited with creating the Stanford-Binet IQ test, which is still widely used today. Terman’s version of the test included a broader range of questions and was used to identify gifted children as well as those with learning disabilities.

The IQ test quickly gained popularity and was used to measure intelligence in a variety of contexts, including employment, education, and even in the military. However, the test has also been criticized for its cultural bias and limitations in measuring intelligence, particularly in areas such as creativity and emotional intelligence.

Despite its criticisms, the IQ test remains a widely recognized measure of intelligence and has undergone numerous revisions and adaptations over the years. Today, the test is used in a variety of settings, including schools, workplaces, and research studies.

In conclusion, the IQ test was first invented in the early 20th century by Alfred Binet and Theodore Simon as a tool for identifying children with learning disabilities. Since then, it has undergone numerous revisions and adaptations and has been used to measure intelligence in a variety of contexts. While the IQ test has its limitations, it remains a widely recognized measure of intelligence and continues to be used by psychologists and researchers today.
