I'm surprised how many people here don't understand the inherit biases IQ tests have.
In order for something to test intelligence you shouldn't be able to improve your score by learning, practicing, or studying. Scores should be reproducible. I've yet to see an IQ test that didn't test skills you could improve by practicing.
They also assume knowledge. For example, the IQ test I had when I was young included word comparisons. This tested vocabulary more than intelligence. Someone who didn't have a formal education or didn't know English well would score lower regardless of their intelligence.
IQ is not highly regarded in psychology. It's more reliable than garbage like Meyers-Briggs but is not a true test of intelligence.
