What is IQ and How Is It Measured

IQ (Intelligence Quotient) is a numerical measure of a person's general cognitive abilities relative to their age group — not knowledge, education, or experience, but the brain's ability to process information, find patterns, and solve novel problems.

Where does the number come from?

An IQ test measures how quickly and accurately you handle tasks that are independent of culture or education: matrices, number sequences, spatial patterns. Your score is compared to a statistical norm — the score distribution of a large sample of people your age.

The average score is 100 points. About 68% of people fall in the 85–115 range.

Can you improve your IQ?

The IQ score itself is relatively stable. But cognitive abilities can be trained: regularly solving logic problems, reading, and learning new skills improve information-processing speed.
