Now, that there's a particularly smart observation. IQ tests of
any given form are subject to biases, and those biases can be along
cultural, linguistic, educational or gender lines. The fact is that
after nearly a century, nobody's yet figured out how to measure
Spearman's g - not even
those with 198 IQs. 
Of course, there's also the issue of what the number IQ actually
means. It's quite simply (mental age/chronological age)*100.
Translated, a 12-year-old with an IQ of 198 is fairly equivalent to
a 24-year-old with an IQ of 100. Not much to write home to mum
about, is it now?
