+IQ (intelligence quotient) is a non-perfect but [still kind of useful](good_enough.md) measure of one's intelligence, it is a numeric score one gets on a standardized test that tries to estimate his intellectual ability at different tasks (logic, memory, language skills, spatial skills, ...) and express them with a single number. The tests are standardized and the scoring is usually tuned so that the value 100 means average intelligence -- anything above means smarter than average, anything below dumber than average. IQ is a quite controversial topic because it shows intellectual differences between [races](race.md) and sexes and clashes with [political correctness](political_correctness.md), there is also a great debate about "what intelligence even is" (i.e. what the test should measure, what weight should be given to different areas of intelligence), if it is even reasonable to simplify "intelligence" down to a single number, how much of a cultural bias there is (do we really measure pure intellectual capacity or just familiarity with some concepts of our western culture?) and the accuracy of the tests is also highly debated (which can be an issue if we e.g. start using IQ tests to determine who should get higher education and who shouldn't) -- nevertheless it's unquestionable that IQ DOES correlate with intellectual abilities, IQ tests are a tool that really does something, the debates mostly revolve around how useful the tool is, how it should be used, what conclusions can we make with it and so on. Basically only people with the lowest IQ say that IQ is completely useless.
