So are you saying that you can’t improve your intelligence and you’ll always have the same intelligence level, predetermined at birth, for the whole of your life? I don’t really think this is the case. I’m pretty sure that is widely known that you can improve your intelligence by training / practicing. If the IQ test results are improved with training then it is something that attests their value beside other bullshit tests that don’t improve with practice.
