What is lowest and highest intelligent IQ numbers?

Answer 1

The IQ is standardised with mean 100 and standard deviation of 15. This means that 99.9% of the population will have an IQ between 50 and 150. Also, the further you move from 100, the greater the margin of error so IQs below 50 or above 150 are very unreliable measures.

There are doubts about the value of IQ scores even within that range because different IQ tests give different results. There is also the question of the disparity between what the test purports to measure and what it actually measures (the ability to do tests!).

And before you think this is all sour grapes, I have scored exceptionally high on every IQ test that I have done.
