Ideology and Censorship in Behavior Genetics
by Prof. Glayde Whitney
(Past President Behavior Genetics Association Florida State University, Tallahassee, Florida)
Vol. 35, Mankind Quarterly, 06-01-1995, pp 327.
Presented below is the entire text of my presidential address presented
to the Behavior Genetics Association (BGA) on the occasion of its 25th
annual meeting at Richmond, VA on the second of June, 1995. Since the journal
Behavior Genetics is sponsored by the BGA, some explanation is required
as to why this presidential address is not published in the Association's
own journal.
The primary topic of the address was ideologically-based dogma and
taboo hampering the pursuit of knowledge in the science of behavior genetics.
The response to the address has been such a parody of political correctness
that it might appear to be an instance of collusion between the perpetrator
and the detractors for the purpose of exposing an absurdity of our times.
However sadly, there is no collusion. Both the author and the detractors
appear to be sincere.
The address was presented at an evening banquet. The very next morning
at a meeting of the BGA Executive Committee the author was shunned except
for a brief scolding, and was the recipient of demeaning ad hominem asides.
The Executive Committee busied itself with how to distance the BGA from
the offensive talk. The editor of Behavior Genetics refused to publish
the paper (contrary to understood policy) and the Executive Committee voted
(with one abstention - mine) to issue an official statement of denouncement.
Then shortly after the meeting there began a call for the author to resign
from the BGA. As stated in a public mention of the affair (Science, 1995),
officers of the BGA, and a few others, began to post condemnatory "open
letters" on the BGA's electronic bulletin board.
The issuers of these calls for resignation seem to have lost track,
in the finest Lysenkoist tradition, of the many distinctions between scientific
organizations and political/religious organizations. Scientific organizations
are composed of scientists with some common interests, wherein science
consists of alternative hypotheses, the truth value of which is judged
by their congruence with observable data. Typical as a scientific organization,
the BGA bylaws state purposes which include the promotion of scientific
study, assistance in training of research workers, and dissemination of
knowledge. Nowhere in the BGA bylaws is there a creed or a listing of necessary
beliefs.
On the other hand, political/religious organizations usually have
an official creed, or party platform, to which members swear fealty. Those
heretics that violate the faith are typically shunned, expelled, or forced
to resign. Science has no heretics, and honest science does not thrive
in an atmosphere of inquisitional control (Whitney, 1995). A century ago
Andrew White (1896/1965) wrote an excellent historical account of the warfare
between science and ideology. Although the battlefields shift, the war
continues.
It would be highly misleading to leave the impression that the author
is alone, adrift in a sea of condemnation. On the contrary, private letters
of support and commendation greatly outnumber the public critics. In view
of the attempt. at censorship, I greatly appreciate the editors of The
Mankind Quarterly providing an archival repository for the address:
Twenty-Five Years of Behavior Genetics
Today there are more and better data concerning genetic influences on
behavioral and neuroscience variables than ever before in history. We have
tremendously benefited from the revolution in molecular genetic techniques
- the new genetics. In 25 years behavior genetics has come from being a
small field on the fringe of the social sciences to being recognized as
central to an understanding of the human condition (Wiesel, 1994). Just
a few weeks ago Science noted that the new director of NIMH should be someone
who appreciated the role of genetics in mental health (Marshall, 1995).
This is an amazing shift from 25 years ago when behavioristic environmental
determinism still reigned supreme. We are obviously well into a paradigm
shift of major dimensions, perhaps a true Kuhnian revolution in Science
and Society (Barker, 1985; 1992; Kuhn, 1970). In the future it might be
referred to as the Galtonian Revolution, on a par with the Copernican.
The shift is but one illustration of the long-term self-correcting nature
of science: Objective investigation of the real world, conducted with integrity
and interpreted without intentional ideological bias, can eventually lead
to real advance.
As has sometimes been the case for these after dinner talks, I want
to take just a few minutes to share with you some personal reminiscences
and some personal views. Twenty-five years ago I got my first full- time
faculty position. This was after student days at Minnesota, a bit of a
time-out for military service, and a post-doctoral stint in Colorado. At
Colorado the Institute for Behavioral Genetics was a wonderful setting.
Gerry McClearn and John DeFries, along with Jim Wilson, were running the
place. There were a bunch of stimulating graduate students around: I recall
Tom Klein studying the taste of mice and Boris Tabakoff messing with alcohol.
Doug Wahlsten and I were side-by-side post-docs, Joe Hegmann had just left
and Carol Lynch was just arriving. Wonderful friends and colleagues, all
of them. The best of days in a stimulating environment.
Well then, I got hired to represent behavior genetics in the neuroscience
program at Florida State University. A good program but vastly different
in orientation. Not a lot of geneticists. I was there only a brief time
when one of the old-timers who ran the place came by for a friendly chat.
As polite southerners do, he began with a lengthy discussion of weather,
trees, traffic, chiggers, and children. And then, finally, by-the-way,
he said "Glayde, you know we hired you because we want genetics in
our psychology program, but, as a Professor at a southern university, we
hope you will have the good sense to keep away from that human business.
Because of your location you would have no credibility, and none of us
need the flak"!
Well. That in fact was consistent with my plans, I was busy setting
up a mouse laboratory at the time and sure-enough had enough good sense
to do passably well with mouse research. After all, I've still got the
job and I've been invited here tonight.
To understand my mentor's concern, we need to view it in historical
context. 1970 was an interesting time. Tallahassee, being a state capital
with two state universities, had already had its share of demonstrations,
riots, burning and looting. It was in 1970 that Black Panther supporters
got around to killing jurors and a judge; 1970 that a mathematics building
was bombed on the campus at Wisconsin, also with loss-of-life (Collier
& Horowitz, 1995).
It was also in 1970 that our colleague Arthur Jensen was taking a lot
of flak (Pearson, 1991). As everyone in behavior genetics knows, Jensen
published an interesting review paper in 1969 (Jensen, 1969). Interesting
but hardly ground breaking. As a student at Minnesota, I had had the course
in differential psychology. With interesting textbooks (Anastasi, 1958;
Jenkins & Paterson, 1961) and team taught by such professors as Lykken
and Meehl. We had considered fifty years worth of data, and various interpretative
theories. Jensen in 1969 had a few new data, by-and-large consistent with
all that had gone before. No big deal scientifically, at least not to any
student of behavior genetics from Minnesota. But obviously a great big
deal in some circles.
Over the intervening twenty-five years it has become obvious that Jensen's
sins were, and continue to be, two-fold. First, he did not stay within
the confines of a reigning dogma, and second, he violated a current taboo.
The dogma of course is that of environmental determinism for all important
human traits. This dogma has relaxed in recent years, at least for individual
differences, and at least within science. But the dogma has not relaxed
for group differences and has not relaxed within politics as differentiated
from science. The attacks on Jensen, and by extension on all human behavior
genetics, are clearly political, ideological, philosophical.
The Marxist-Lysenkoist denial of genetics, the emphasis on environmental
determinism for all things human, is at the root of it (Davis, 1986; Medvedev,
1971; Pearson, 1991; Weiss, 1991). Economic oppression is at the root of
all group differences and don't you dare say anything else. The Marxist
invasion of left-liberal political sentiment has been so extensive that
many of us think that way without realizing it.
It has been suggested that I should talk about "Marxitis"
that is, the Marxist infection of ideas. Many of the scholars that suffer
from Marxitis do not realize that they are infected. The symptoms of this
disease include an intellectual bias, an insistence on environmental determinism
as the acceptable cause of group differences. In severe cases, it includes
an unbending intellectual absolutism akin to medieval scholasticism. It
is lethal to honest science.
A couple of quotes from heretics that have left the movement: "the
utopianism of the Left is a secular religion . . . . However sordid Leftist
practice may be, defending Leftist ideals is, for the true believer tantamount
to defending the ideals of humanity itself. To protect the faith is the
highest calling of the radical creed. The more the evidence weighs against
the belief, the more noble the act of believing becomes" (Collier
& Horowitz, 1995, p. 246).
There is a "readiness to reshape reality to make the world correspond
to an idea" (Collier & Horowitz, 1995, P. 37). There is a "Willingness
to tinker with the facts to serve a greater truth" (Collier &
Horowitz, 1995, p. 37). And so it has obviously been with many of the critics
of behavior genetics. Over the last twenty-five years, as the scientific
data accumulate, as the paradigm shifts, the stridency of the critics intensifies.
Driven by ideology and not constrained by the truth, when all else fails
they engage in misrepresentation and character assassination. They accuse
their targets of committing the very propagandistic excesses that they
themselves are doing (Avery, et. el., 1994; Beardsley, 1995; Brimelow,
1994; Gould, 1994; Kamin, 1995; Lane, 1994; Miller, 1994; Murray, 1994;
Weyher, Lynn, Pearson, & Vining, 1995).
Some one among them coined the term "Jensenism". Near as I
can tell "Jensenism" consists of scientific integrity, outstanding
technical competence, and objective honesty.
Well, Jensen's first sin was to venture outside the Left-Liberal Marxist
dogma of environmental determinism. His second sin was even less forgivable,
he violated a Taboo: He mentioned race outside the environmental envelope.
The Behavior Genetics Association has been in existence for 25 years. The
end of the Second World War was 50 years ago. Peter Brimelow (1995) has
suggested that since the second world war we have been suffering what he
calls "Adolf Hitler's posthumous revenge on America" (Brimelow,
1995, p. 1). The posthumous revenge is that the intellectual elite of the
western world, both political and scientific, emerged from the war "passionately
concerned to cleanse itself from all taints of racism or xenophobia"
(Brimelow, 1995, p. xv). The aversion to racism has gone so far that the
scientific concept of race itself is frequently attacked. The results are
often ludicrous. For example, on three adjacent pages of a recent issue
of Science we are led to believe that races do not exist, but that it is
important to assess the genetic diversity of remaining native populations,
and a black scientist at a black university should be funded to investigate
the black genome as a route to appropriate treatment of diseases of blacks!
(Kahn, 1994). The many and important distinctions between objective investigation
of group characteristics, and prejudicial pejorative values are lost in
a political atmosphere where objective reality is sacrificed to political
creed.
Brimelow suggests that the term "racist" is now so debased
that its new definition is "anyone who is winning an argument with
a liberal" . (Brimelow, 1995 p. 10, italics in original). He suggests
that we feel uneasy because we have been trained - like Pavlov's dog -
to recoil from any explicit discussion of race.
Let's test Brimelow's theory of emotional conditioning with just a couple
of illustrations of data. Here and now is the setting for our experimental
test. Here we are scientists, sophisticated with regard to behavior genetics.
We tell our students that we are the scientists concerned with the causes
of individual and group differences (Fuller & Thompson, 1978; Rowe,
1994). Any time you observe a phenotypic difference between definable groups,
it is a reasonable scientific hypothesis that the difference might be caused
by environmental difference between the groups, or the difference might
be caused by genetic differences between the groups, or by some combination
of genetic and environmental differences. Elementary.
Now to look at the data relating to the Brimelow test, we include five
figures.
The first figure has data from a UN demographic yearbook (United Nations,
1994). The variable here is murder rate per 100,000 of population, for
a few countries. This is a typical representative figure: Among so-called
advanced nations, or industrialized nations, the United States suffers
a high murder rate. The environmental determinists have many theories,
some complex and all critical to aspects of American society. Often we
are asked, for instance, "why are Scandinavians in the U.S. so much
more murderous than are Scandinavians in Scandinavia?" The answer
is that they are not. The premise of the question is false.
The second figure has the same "industrialized" European,
largely Caucasian, countries along with an estimate of the murder rate
among whites in the U.S. Surely nothing to be proud of, the murder rate
among whites is pretty consistent across countries, the rate among U.S.
Caucasians is identical to England, and somewhat lower than the two Scandinavian
countries. The United States is of coursea multicultural, racially diverse
country. This same point has been made previously, with data from different
sources (Taylor, 1994).
The third figure has the murder rate for the United States across 22
years, by race. Obviously quite consistent, approximately a 9-fold difference
averaged across years (Uniform Crime Reporting Program, 1988).
Like it or not, it is a reasonable scientific hypothesis that some,
perhaps much, of the race difference in murder rate is caused by genetic
differences in contributory variables such as low intelligence, lack of
empathy, aggressive acting out, and impulsive lack of foresight.
The United Nations has a lot of indexes; another one is the HDI (that
is, Human Development Index). The HDI is meant to index a bunch of desirable
characteristics (such as longevity, knowledge, real income, etc.). Overall,
the U.S. ranks fifth among the nations in the HDI. To get fifth on the
international list, you combine U.S. whites, who rank first, with US blacks
who rank 31st, a level similar to some other black countries (Eisenberg,
1995), and this after more than a generation of racially preferential social
policies. If you equate for IQ, U.S. blacks are actually doing at least
as well as U.S. whites (Herrnstein & Murray, 1994).
Back to murder rates. Environmental determinists seem generally befuddled
by murder, and most of their social policy suggestions, when implemented,
seem to make matters worse rather than better. Of course environments do
matter, and environmentalistically based policies do have an impact. In
1994, the murder rate in New Orleans, LA, reached 86.5, while in Richmond,
VA, the murder rate was 77.9, for second-worst large city in the United
States (Perlstein, 1995). Obviously, the environmental determinists are
not benign; they do not occupy a moral high ground; their policy recommendations
do have consequences.
We can do a pretty good job of predicting differential murder rates,
simply by considering racial composition of the population. For example,
in the fourth figure we have aggregate data across the 50 states of the
United States. The simple correlation between murder rate and percent of
the population that is black, is r= +0.77. For Figures 4 and 5, the homicide
data are from the U.S. Department of Justice (1981), while the population
percentages are from the 1980 census (Race, 1981). I know of no environmental
variable that accounts for more of the variation. Rather than the 50 states,
we can look at all of the 170 cities in the United States that had a 1980
population of at least 100,000. With 170 data points, it would make a messy
scatter- plot; the overall correlation between murder rate and percent
of the population which is black is r=+0.69 (Kleck & Patterson, 1993;
Kleck, 1995).
Simply for illustrative purposes, the fifth figure is the rate-by- state
as in figure 4, but with the values for Washington, DC included. As you
can see, the very high murder rate for Washington, DC is simply what one
would predict, given knowledge of its population composition.
We could go on-and-on, there are books-full of variables (Baker, 1981;
Rushton, 1995). But this is enough to conclude the Brimelow Test.
Do you have an emotional reaction? I know I do: Uncomfortable to even
consider; Anxious; Repulsed; Upsetting. I conclude that I have been quite
thoroughly conditioned. The Taboo against considering race runs deep. But
some of our social problems continue to get worse.
I would like to conclude on an uplifting and happy note. But what to
say? Perhaps the optimistic prediction that over the next 25 years, as
we get further into the second century of the Darwinian revolution, we
in behavior genetics will do for group differences what we already have
accomplished with individual differences.
