the dominance of the genetic origin of IQ is beyond question.
It is more complicated than that statement. It is
more nuanced.
First, genetic "dominance" does not display itself in cases
when the genetic factors are overwhelmed by environmental factors.
Take for instance the seed of a plant. If you plant the seed
and do not adequately water it, or is is planted in a cold period
in which it does not warm up, or it does not get enough sunlight
the plant will be stunted and will not achieve its genetic potential.
If this is done with a large group of plants surviva will not depend
on factors which are otherwise important under optimal conditions
for development. Under high stress conditions a "weak may inherit
the earth" factor can occur.
The study showed that a child's IQ will not develop to its potential
if raised institutionally. It is better to be raised in a home
situation and best raised by biological parents.
These three environments gave IQ levels of 73, 81 and 109,
which is a large increase. In fact too much to be taken
without a grain of salt. But what must be true is that
in suboptimal environments full realisation of the
potential provided by genetic inheritance does not occur.
This has been shown by other studies.
I also would doubt the IQ variations are bell shaped in a
strongly repressive environment. They are more likely
to be skewed. Therefore in the IQ average of 73 there will
be more IQs above 73 than below. With the "81s" the skewing
will be less but still present.
Undoubtedly inheritance does play into it. But without a
nuturing environment and also exposure to various opportunities
in life many never reach their potential.
True, but in terms of intelligence, genetics still determines our
ultimate potential. A good environment is important for lots of
reasons -- intelligence being just one. It's too bad we can't confront
the importance of intelligence, and the fact that we don't all arrive
on earth equally gifted. The first step is admitting that our
differences lead to a variety of outcomes in life that may impact the
need for public assistance, criminality, and financial and educational
success. Once we get beyond that hurdle, perhaps there are logical
steps that can be taken -- both political and scientific.
I have two grandsons adopted from third world countries --.
Colombia and Brazil. They came from extremely stunted living
environments. One is now age 16 and has been in a gifted
kids program since first grade. The other is only 11 months
old but videos show a bright eyed, curious and always happy
child.
I often wonder how these boys would have turned out had they
remained in the homes they were born in. And how their parents
would have tested on an IQ test.
