Also I will debate the 3 points per decade. Not
that it didn't happen , but why. My theory is
that you most only measure children before Pre-K.
The enviroment has change so much that after that
they are learning to many facts that help the IQ
test. One might also look at countries that have
not improved their general education. Should there
be a difference in these groups, one can get a
measurement how much the general enviroment has
changed the IQ. Then, I would think that more of
the upper IQ groups are being tested; with a
larger population. And I also beleive that there
are many populations that are decreasing in IQ.
I do not beleive that natural selection is
increasing the IQ ; but right now going down in
a total picture. Hope this is something to think
about in the other direction, sorry I have
very few facts.
