Frequently Asked Questions
Definition of IQ Tests
The simple answer is that "IQ" is short for "Intelligence Quotient". It is a numerical measure of a person’s reasoning/logical and problem solving ability.
When the testing protocol and methodology is correct, it is an extremely accurate gauge on a person's intelligence level, and in particular how well they can use information/logic to solve problems by accessing short and long term memory and combining it with critical thinking and reasoning. IQ tests begin to assess this by measuring short- and long-term memory.
History of IQ Tests
Modern intelligence testing was developed in the early 2oth century, by Alfred Binet & Theodore Simon. The tests were commissioned by The French Department of Education, and was intended to test individuals so it could distinguish mentally challenged children from "normal" children. The result was the Simon-Binet IQ Test.
These early rudimentary tests would combine the child's age with the test score to give a score a score between 0-1,000. While these tests were very simple, they were extremely popular and became widely used in Europe and then soon after in the United States and Asia.
