A normal IQ test includes several tests that measure intelligence, such as the ability to recognize patterns, remember things quickly, do math, and think critically. People often get the wrong idea about IQ tests, thinking that they test all the information you've learned over the years. Instead, they actually test your ability to learn.
The first IQ test was made in the early 1900s. Since then, it has changed a lot. In the same way that they tested people's ability rather than anything they had learned in the past, their goal hasn't changed, and neither has the way they do it.
The IQ test has been changed many times, but the Wechsler Adult Intelligence Scale (WAIS) is the one that is most often used. This test, which was made in 1955, was different from earlier IQ tests that looked at different mental skills, like verbal, numerical, spatial, and reasoning intelligence. There has been a change to this test, the WAIS-IV, since it was first made.
