Imagine if the average IQ of the entire population were shifted up by several points.
I guess it depends on the starting point. I imagine that shifting the average from 85->90 would have a much bigger effect than shifting from 105->110. Most studies seem to show a pretty sharp diminishing returns when correlating IQ points to just about any measure of 'success'.
