Of course the article was interested in how much IQ variance
contributes to income inequality, but I started thinking about how
this time dependence would extend given longer lifespans. (Warning: I
never read the Bell Curve.)
Holding constant the IQ variance but extending lifespan, would income
variance at the end increase? That is, the longer time you have to
work and invest in learning things, the more benefit you can get out
of your higher IQ? Or would the same income variance spread out over
a longer time scale?
Varing the IQ variance for a fixed lifespan, is there some maximum IQ
beyond which IQ doesn't help income within the lifespan, so that
longer lifespans are required to take advantage of it?
Or am I tring to read too much into a few noisy data points?
