$this->bbcode_second_pass_quote('', 'S')aying a 30 y/o has the mind of a 24 y/o is just moronic.
The 30 y/o in this case is considered to have a chronological age of 16, with 16 also being the average mental age for adults, as that is widely considered by the developers of such tests to be the point at which the brain has matured.
(Mental Age)/(Chronological Age)*100 = IQ
I think that's how they calaculate it at least, if wrong sonmeone correct me.
So for an adult to have a mental age of 20(regardless of their chronological age, as 16 is the highest these tests count), they'd have an IQ of 125. An adult with an IQ of 100, being normal, will have a mental age of 16, no matter whether they are 30 years old or whatever.
But personally, I think IQ is a fairly useless measurement.
