@Oskar: IQ tests are extremely biased by their nature. They are designed to test what you are capable of learning during the test. I.e. they assume you have a certain skillset going in to take them, and they play on your ability to learn other skills which are presented in the test.

This is supremely difficult because different cultures (even within the same geographical area) can favor very different modes of thought as "intelligent." A test which assumes you've been to school and studied information from books is not going to test a person's IQ who dropped out of school at a young age. That is no reflection on that person's intelligence, merely an indication that the test is broken by their circumstances. They do not meet the assumptions of the test-designer as per their background.

Similarly, a test which adequately and fairly described the dropout's intelligence would almost certainly fail at assessing a college graduate's intelligence. These people consider very different behaviors to be expressions of intelligence.


If you are studying for the test, you're literally breaking it. Any results would be moot. I mean... it'd be a pretty stark critique of your study habits otherwise.

If you want a "fair" assessment of your intelligence, you need to seek out an IQ test which is biased toward your socio-economic and educational background and cultural preferences. Then you need to NOT study for it.
