I have decided I have been projecting in trying to understand the
resistance many people have to the high-heritability, low environmental
influence on adult abilities. I will set forth our story, but I want to
read what others think.
I don't think Tracy and I had
more than an informal consensus when we married of how much of
children's intelligence, determination, reading skill, charm (...one
hundred other abilities) is due to genetics . I think we would have
acknowledged that there was some. Yet it was an era when all psychology,
psychology, anthropology, and educational theory insisted that
environment was nearly everything, and we absorbed the lessons of our
times. Our behavior right from the outset illustrates our belief that
environmental factors are enormous and critical. We started teaching
Sunday School and taking in foster children within a few months of
marriage; she was reliably The Book Aunt right out of the gate. We read
to Jonathan the first day he was born, and did not miss many days even
when he was well into school. Family devotions, expressions of
affection, arts, history, science were creatively attacked year upon
year. It spilled out to our friends' children and we eventually adopted
a few. We stopped at every historical marker and chatted about it
afterward; we went to medieval events in costume, with instruction on
the way there and the way back. As the twig is bent...
We were pretty much nuts, but mostly joyfully so and it mostly (not always) worked,
for our family and those we were in contact with. We embraced and tried
to put into play all the child-raising knowledge we could get our hands
on: critical periods and the other Montessori tropes; learning styles;
careful expositions of how one taught repentance and forgiveness;
multisensory instruction; something pretty close to a homeschooling
curriculum on top of sending them to private Christian schools;
preserving independent learning and autodidacticism. Even as I began
learning in the 1980's how much is hardwired, there was significant
inertia for...well, we've still got Kyle, who is 20, and we still
discuss exactly how we are going to present certain ideas, undermine
others, and create an environment for him to learn his next life lessons.
From
this all of you can make some good guesses why I would resist that idea
that this was mostly extraneous effort. I am also deeply moved by the
unfairness of a world where a great deal of child's outcome is ranged
even before she is born. I believe that mild alterations in environment
can create large differences, in that you might grow up in
Michigan instead of New Mexico, or marry a woman who develops a terrible
illness, or hear a particular preacher on a particular day. And
differences might of course lead to diverse outcomes. Yet I am
also aware that you might be a shy chemical engineer with a worrisome
attraction to children but no expression of that no matter where you
ended up living, and end you life with one of ten very similar
biographies. (There does seem to be a nonenvironmental, likely random
element that may explain as much as 50% of the variance on some traits.
That's a little different.)
Twice over at Maggie's in
the past day or so there has been discussion of women in math and
science, and the usefulness of pre-K. Greg Cochran has just yesterday
gone over some of the standard data about group differences, with
specific references to famous academics who seem unable to absorb even
the simplest parts of it. There is this persistence, a stubbornness, in
clinging to the idea that so many pathologies are fixable if we just
make the proper changes in the environment. I have mostly assumed that I
understand this reluctance to accept genetic explanations, because I
read my own feelings into it. Yet my feelings may not be at all
representative.
We accept that height is largely
heritable, but weight...not so much. We see that a musical knack and
sometimes genius seems to be "just there," and not teachable, yet we
still focus on the 10,000 hours of hard work as the key. For schools
especially, liberals and conservatives have visions of how things should
be organised, and we get very upset about the cultural discussions.
Yet, why? There is this idea that we just don't want to believe, no matter the evicence.
Those
who have some insight into how abilities and education are viewed in
other countries, especially non-Anglospheric, non NW European countries
are encouraged to weigh in on that as well.
