You free to think what you want ;)

It is a fact that the IQ is constructed. It is not random based.

For example, If we used the Gaussian curve as our guide, we would expect to find an IQ of 160 or above among about one in 31,600 children. In fact, we find an IQ of 160 or above occurring in one in about every 1,125 kids

And yes, I may be nitpicking. I love philosophy after all ;)
