IQ was originally derived as the ratio of mental age to chronological age, multiplied by 100. Therefore, if a 10-year-old had a mental age of 12 (the average mental age of a 12-year-old), the child's IQ was 120.

okay.....what catagorizes a mental age? everyone has a different "mental age". whats different in a 50 year olds mental age and a 49 year old? the iq stuff has serious flaws.
