You have got your thresholds wrong. http://en.wikipedia.org/wiki/Mental_retardation#IQ_below_70 Also, the distribution is by definition normal, and I have hard time believing 15% of population is retarded. That would mean about 1 in every 6 person I met is retarded, a number too big to believe. Now 3 genius/3 dumb out of 100 is more like what my experience has been. |
