For some groups there is a correlation between income and IQ over a
number of decades. If we postulate that there is some factor that
causes both higher IQ and higher income it seems likely that the
income results will compound over time.

I don't think IQ differences above a certain level are meaningful but
let's assume they are or deal with IQ's below that level. Given a
large number of income generating puzzles some percentage of them
will benefit from a higher IQ, the more difficult one's coming up
less frequently. Again I think the compound interest analogy is good
with very high IQs adding small percentages which take a long time to
become significant.

There is a lot of IQ and income data out there so I suspect you could
develop a number of testable hypotheses. It is interesting but
I can't think how the results would be useful. In any case I doubt
you will get a chance to reap the full benefits of your own prodigious
IQ before intelligence increasing technology becomes widely available.
