Are you going to take the vaccine?

It's true that IQ does encompass some knowledge that is taught, but I am not sure how efficacious of a factor that is of intelligence. 

IQ tests are just statistical population models, where the questions are statistical samples of large questionnaire based surveys which are mostly culturally neutral, mostly using logic puzzles and such. This is why 100 is always the average for any given year, it's the center of the bell curve (but the avg IQ of 100 in the early 1900s would be like 85 now, theoretically).

So the IQ test measures what was intended to measure by the questions already answered by the population sample base which consist of discerning various types of abstraction, logic, etc (I think there are a dozen catagories). Knowledge isn't supposed to be part of the test, except for the rudimentary required to decipher the question (like numbers or identifiable things). Jordan Peterson had a good explanation of how it is created and what is catagories in his Personality seminars at UofToronto
