There is a strong correlation between high IQ and wealth.
I don't see how all humans from all cultures could score the same unless they were all trained to process in the same way too. As IQs are rising generation by generation then it must be a cultural thing rather than a biological thing. You don't evolve more intelligence in one generation.
If the IQ test was for funny comments you'd be right up there gentlemand.
You come out with some corkers
His humour is definitely great
About the increasing iq - it is called the flynn effect and i think its cause is mainly better nutrition and higher social standards overall.
(A counter example could be east asia though)
About iq:
It is highly correlated with intelligence.
Iq test usually check visuo-spatial (e.g. math,pattern) and verbal (e.g. language) intelligence.
A proper iq test would not include socio specific knowlegde e.g. you could test an amazonian native or an european (see raven matrices).
Imho ibian got it pretty good with the word potential.
A high iq person has high intellectual potential but that doesnt mean he can/will use it.
