IQ – a measure of intelligence: what is it and how accurate is it?

IQ is one of the most debated topics in psychology and human developmental science. But what is IQ, and how accurately does it measure intelligence?

What is an IQ?

IQ is short for “intelligence quotient.” It is a numerical estimate of a person’s level of intelligence that is obtained by solving various tasks and tests. IQ is usually measured between 0 and 200, where 100 is considered an average value.

History of IQ

The history of IQ measurement began in the late 19th century, when French psychologist Alfred Binet developed the first intelligence test. In 1916, American psychologist Lewis Terman created the first IQ test, which became widespread in the United States.

Since then, the IQ has become one of the most popular ways to measure intelligence. However, despite its widespread use, many scientists doubt the accuracy of this measure.

How is IQ measured?

IQ is measured by a variety of tests that assess different aspects of intelligence, such as logical thinking, abstract reasoning ability, memory, and response to new situations.

One of the most famous IQ tests is the Raven test, which was created in 1938. This test consists of 60 questions that assess the ability to think abstractly and reason logically.

How accurately does the IQ measure intelligence?

Although the IQ is widely used to measure intelligence, many scientists believe that it is not the most accurate method. Some scholars believe that IQ does not take into account important factors such as social and emotional intelligence.

In addition, IQ can be elevated or lowered depending on various factors such as education, health, and even mood.

Expert Opinion

“The IQ measurement can be a useful tool for assessing intelligence, but it should not be the only criterion,” says psychology professor John Smith.
