Well, as long as you're not under the impression that
all "psychological or physical health issues" are determined or decided by genetics. And
I guess it would be useful to keep in mind that there's quite a bit of speculation involved by those who are attributing certain specific
psychological or physical health issues, or traits, exclusively to genetics (i.e. these are not "proven facts" as you put it yet still marketed under
the marketinglabel "science" in scientific literature). Down's syndrome is a good example of a psychological and physical health issue that is
directly linked to genetics, but for some others, it's not all that clear-cut as it is sometimes made out to be by those trying to sell their genetic
research as something valuable (worth doing, worth being funded). Financial factors can have a significant impact on the so-called "science" like
that.
Ideas about how to better the human race are not new. Some 2,300 years ago, the Greek philosopher Plato wrote: “The best of either sex should be
united with the best as often as possible, and the inferior with the inferior as seldom as possible.” It wasn’t until more recent times, however,
that efforts to upgrade the human family began in earnest. This discipline was called eugenics.
The term “eugenics” was coined in 1883 by Sir Francis Galton, a British scientist and cousin of Charles Darwin. The word comes from Greek terms
meaning “good in birth” or “noble in heredity.” Galton knew that various flowers and animals could acquire certain desirable qualities through
selective breeding. Might not humanity be improved by similar methods? Galton believed that it could. He reasoned that if a fraction of the cost and
effort devoted to the breeding of horses and cattle were spent on “the improvement of the human race,” the result would be “a galaxy of
genius.” (i.e. providing an incentive to fund and/or support eugenicists, eugenics programs or politicians, lobbyists, scientists and academics that
support or promote such programs, so they can spend it on something supposedly worthwhile)
Influenced by the writings of Darwin, Galton reasoned that it was time for humans to take control of their own evolution. During the early decades of
the 20th century, Galton’s ideas became extremely popular among politicians, scientists, and academics, in both Europe and the United States.
Reflecting the popular notions of his day, the leader of a powerful nation wrote: “Society has no business to permit degenerates to reproduce their
kind. . . . Any group of farmers who permitted their best stock not to breed, and let all the increase come from the worst stock, would be treated as
fit inmates for an asylum. . . . Some day we will realize that the prime duty of the good citizen of the right type is to leave his blood behind him
in the world, and that we have no business to perpetuate citizens of the wrong type.” Those words were written by the 26th president of the United
States, Theodore Roosevelt.
In fairs and expositions in both Britain and America, the laws of genetic inheritance were depicted, often on a vertical board displaying an array of
stuffed guinea pigs. They were arranged to show the inheritance of fur color from one generation to the next generation. The point of the exhibits was
made clear by accompanying text. One chart stated: “Unfit human traits such as feeblemindedness, epilepsy, criminality, insanity, alcoholism,
pauperism and many others run in families and are inherited in exactly the same way as color in guinea pigs.” Another exhibit placard asked: “How
long are we Americans to be so careful for the pedigree of our pigs and chickens and cattle—and then leave the
ancestry of our children to
chance?” Now I know that the implication above that criminality, insanity, alcoholism, pauperism and the vague "many others [traits]" are
exclusively determined by genetics, a requirement for the suggestion you can breed them out by selective genetic breeding, is highly dubious, to say
the least. We actually have quite a bit of evidence that the ones specifically mentioned there by name, are less determined by genetics than by
environment (experiences, upbringing, social environment, etc.). In some cases, someone's genetics is not a factor at all in the cases of criminality,
insanity, alcoholism and pauperism. Suggesting that among the mentioned "many others [traits]" that may be true as well (hard to evaluate something so
vaguely specified, but since the other 4 were already such bad examples to supposedly weed out by selective genetic breeding or
genetic
engineering, I suspect someone who thinks that's possible might be thinking of quite a few other traits like those when saying or reading "many
others").
These ideas were not merely intellectual exercises. Tens of thousands of “undesirables” were sterilized in both North America and Europe. Of
course, the definition of who or what was undesirable depended largely on the views of those making the decisions to force sterilization. In the state
of Missouri, U.S.A., for example, legislation was proposed that called for the sterilization of those “convicted of murder, rape, highway robbery,
chicken stealing, bombing, or theft of automobiles.” In its misguided effort to achieve a master race in one generation, Nazi Germany went a step
further. After the forced sterilization of up to 225,000 people, millions of others—Jews, Romanies (Gypsies), the disabled, and other
“undesirables”—were exterminated under the guise of eugenics.
Because of the barbarism of the Nazi era, eugenics took on an ugly connotation, and many hoped that this field of study had been laid to rest, buried
with the millions who died in its name. In the 1970’s, however, reports circulated of scientific advances in the fledgling field of molecular
biology. Some feared that these advances might fuel a return to the ideas that had seduced Europe and North America earlier in the century. For
example, in 1977 a prominent biologist warned his colleagues at a National Academy of Science forum on recombinant DNA: “This research is going to
bring us one more step closer to genetic engineering of people. That’s where they figure out how to have us produce children with ideal
characteristics. . . . The last time around the ideal children had blond hair, blue eyes and Aryan genes.”
Many today would consider it ludicrous to compare the advances in genetic engineering with Hitler’s eugenic program. Eighty years ago, there were
harsh demands for racial purity. Today people talk about improving health and the quality of life. The old eugenics was rooted in politics and fueled
by bigotry and hatred. The new advances in genetic research are fueled by commercial interests and consumer desires for better health. But while there
are major differences, the goal of shaping people to our own genetic prejudices may sound much like the old eugenics.
Besides medical advantages, some see genetic engineering as a way to solve social problems. Between the second world war and the early 1990’s,
academics argued that social problems could be reduced by reforming economies and institutions and improving the environment in which people live. In
more recent years, though, social problems have deepened. Many people have come to believe that the key to such problems lies at the genetic level.
And some now believe that genes play a more important role than environment in influencing in
dividual and group behavior. [continued in next
