Correction
Many times we throw insults around without knowing what we're saying. For instance, I was surprised to read in a book, Public Education in America that many insulting words are actually intended to be scientific measurements of intelligence. In the book mentioned, I found the following chart:
LEVEL.................IQ INTERVAL
Idiot............................. 0-25
Imbecile........................25-50
Moron...........................50-70
Borderline.....................70-80
Low normal...................80-90
Normal.........................90-110
Superior.......................110-120
Very superior................120-140
Near genius.................140 and over
All this time I've been calling politicians and steroid pumping athletes idiots, when in fact they're just morons. My bad.
