measure of 'intelligence' (the quotient part only means it is not an
absolute measurement, but relates to the average). It doesn't have any
correlation with the 'value of what is produced'.
But (to repeat myself) it is difficult to measure 'intelligence' when
we can't even define it rigorously (although we know it when we see

1) Individuals vary widely in abilities;
2) Some of this variation is genetic, some is environmental (starting in
the womb); much of it depends upon social and educational opportunities,
and the individual's interest and effort in assimilating these;
3) Ability to acquire skills and knowledge has itself both a genetic and
an environmental component;
4) Measurement of some components of ability can be done reliably and
some of these can be correlated with achievements valued by the society
to which the individual belongs, with reproductive success, or with
5) AFAIK, all attempts to define some measure of overall intelligence
take weighted sums of components of ability;
6) In principle, changing the weighting of the components can change the
ranking of individuals the ratios of whose component abilities differ;
7) Eliminating environmental effects upon the acquisition of abilities
is very difficult.
I don't have any moral objection to trying to measure IQ, but I have
considerable doubts about anyone's ability to do it in such a way as to
be useful on a world-wide basis (over widely differing societies) or in
discussion of past times.
Measuring IQ, in order for it to include all of the points you mention above, would need to be on an individual basis with handicaps offered for each person. Individual success in one region of the world differs immensely when compared with another region (and another individual). Environment is the key factor for both speciation and IQ.
