Why isn’t it possible for someone to have zero IQ?
In: Biology
There’s a very deep misunderstanding of what IQ is and how it relates to intelligence. Basically, IQ numbers relate to how well you did on an IQ test. The researches then extrapolate that into what your supposed level of intelligence is using a lot of other data, including enviromental factors such as education level, language, reading comprehension, etc, etc.
It’s very debatable how any of that actually extrapolates to intelligence, if it does at all.
For someone to have a 0 IQ, it’d mean that they failed every question of the test (which should have been custom made for the particular population to be tested, there’s no 1 universal IQ test), which is pretty difficult since it has some very easy problems and questions. Essentially, you would have tested someone that was totally incapable of interacting with the given test, like giving a blind person a written test to do. And as in that example, it says a lot more about you as an examiner than the person being tested.
