Some one was saying IQ of 70 than say IQ of 110 or 120 there is no difference to untrained person. Only highly skilled train doctors doing IQ assessment can tell. But the average person cannot tell difference is that true. Saying that if you have IQ of 100 or higher and your friends, family and people you talk to have IQ of 70 you would not be able to tell the difference at all. Also saying IQ test does not test your curiosity to learn, abstract thinking and creativity. That IQ is bogus and lot it does not test you on. If this is true why do we still use the IQ test and so many people so interested in the IQ test and what their IQ score is at?
