Apologies if this is a bit late - I am a bit behind. I just wanted to
add that Denise Drane (in Australia) has pointed out the *ecomonical*
effect of this as well. You have a normal 'bell' curve of IQ and for
individuals below a certain point on the horizontal axis of IQ you
need to have 'special' education provided, and employment options
when they grow up. These are much more expensive than the 'standard'
education and other facilities suitable for the 'normal' population.
So if we have an even small shift of the bell curve to the left, then
there is a dramatic increase in the number of individuals falling
below that cut-off. This can have significant effects on the costs of
government-provided education, etc. (ie our taxes).
