"the average IQ is 140": I tuned out after this, since it is impossible. The IQ is defined as 100 being the average (for some sample population you hope is representative), with 15 as the standard deviation. So you see how 140 can never be the average IQ (although I guess people could be equivalent to a current IQ of 140).
