A Review
\Officer, Charles and Page, Jake. The Great Dinosaur
Controversy. Reading, Massachusetts: Helix Books, 1996.\
Members of this board are well aware of the "dinosaur
controversy" as we have had, as a member, Professor Dewey McLean
who told us his side of the story. We have, in a sense, heard of
the battles over the "Alvarez hypothesis" -- the meteoric
destruction of the dinosaurs at the K-T boundary, about 65
million years ago. This book by Officer and Page offers another,
but complementary, view of that controversy and puts Professor
McLean's personal struggle in context. Briefly, what McLean
experienced in his fights with Alvarez -- the campaign against
him personally, the backbiting and the pettiness, the
rumormongering and the backstabbing -- are not at all unique.
Dewey was not alone: Alvarez could be a mean man and he had
friends in high places and could -- and did -- exert influence
far beyond his own field (physics) and his own university
(Berkeley). In another sense, here is verification of McLean's
interpretations of what happened to him. The book is more,
however, in that this is a revealing "case study" of battles
royal in geology and paleontology. And, reading it, one must
ask: Whoever suggested that science was a gentleman's game?
Quoting from Davis' Lawrence and Oppenheimer, Officer and
Page have it that:
Alvarez most nearly carried the spirit of prewar
Berkeley [where he had joined the faculty in 1938].
Like Lawrence, Alvarez characteristically wanted to
hurry and do big things, and he too tended to treat
other scientists as servants. But he showed much more
positive readiness to cause pain... Alvarez divided
his talent between experiments and public relations...
(p. 81)
And, he was one of five scientists to testify against Robert
Oppenheimer who is regarded as the father of the atomic bomb.
Oppenheimer did not want to see the U.S. go ahead with the far
more dangerous hydrogen bomb and, because of that, Alvarez
concluded he was a "security risk." Again, quoting from Davis'
book:
One of the leaders in the atomic establishment says
that he was appalled by an intimation he caught in 1954
of the way anger and frustration and affected Alvarez'
mind: "I remember a shocking conversation I had with
Alvarez. It was before the Hearings. I want to make
it clear that I am not giving his words but trying to
reconstruct his reasoning. What he seemed to be saying
was Oppenheimer and I often have the same facts on a
question and come to opposing decisions -- he to one, I
to another. Oppenheimer has high intelligence. He
can't be analyzing and interpreting the facts wrong. I
have high intelligence. I can't be wrong. So with
Oppenheimer it must be insincerity, bad faith --
perhaps treason?" (p. 82)
Whoa! A mind like that is bound to find opponents in the
sciences of geology and paleontology. Alvarez's training was in
experimental physics where experimentation is sometimes possible.
In other sciences, consensus must frequently be sought to
substitute for experiments. And Alvarez thought he could produce
consensus by blustering. And he is not the first physicist to do
so -- one is reminded of Galileo's posturing regarding
Copenicanism where, if he couldn't convince opponents with proof
(he didn't have any) he would destroy them with his deft tongue.
Arguments in science which rely on ad hominem arguments are, of
course, not "science" at all. Or are they?
In 1980, at the birth of the Alvarez impact hypothesis,
a majority of scientists were profoundly skeptical of
it. The voices of these skeptics (most of them from
paleontologists and geologists who had been working in
these fields for years) tended not to be heard, and
they complained, often bitterly, among themselves and
to any science editor or journalist whose ear that
could catch. They went unheeded outside the confines
of their own disciplines and the technical journals
devoted to those disciplines.
(Officer and Page) have always inclined to the
notion that Mother Earth -- impresario of a long-running
evolutionary play in an ever-changing
ecological theater -- has plenty of her own techniques
for colluding in the extinction of whole species, even
dinosaurs.
In this book we look at the meteorite impact
theory as it "evolved" over its short life, and at the
scientific efforts, both good and bad, that followed
its announcement. And we given an alternative
explanation, one that existed before 1980 and has been
further enriched in the course of the fracas. We
conclude that the Earth is the major heroine here, a
heroine that may not be as dramatically sexy as the
meteorite theory but one that is also without need for
that rather weak and desperate play of playwrights, the
dues ex machina.
In a sense, this is a shame. For both of us like
a bit of drama with our breakfast cereal as much as the
next person. But the impact theory has not stood up at
all to expert scrutiny. Actually, many theories do
not. In the history of science, theories and
hypotheses are just that -- interesting possible
explanations of observed facts that can be tested,
either in their own right or by weighing them against
others. Among the many hypotheses that prove false,
some have eventually been useful in furthering
scientific understanding. But the impact theory has
not been helpful even in this regard.
Indeed, most of the "science" performed by the
Alvarez camp has been so inexplicable weak, and the
response to it to eagerly accepting by important
segments of the scientific press (never mind the
popular press and the tabloids), that some skeptics
have wondered if the entire affair was not, on the
impact side, some kind of scam. Such an allegation
would have to be backed up by the kind of investigative
reporting that exposed the Watergate scandal, and we
are not qualified to do that...
The demise of the dinosaurs (along with a host of
other more or less contemporaneous life-forms) clearly
occurred for other and more complicated reasons than
impacts from space. These reasons are wholly plausible
and well understood...
The hypothesis was initially advanced in Science in 1980
and it was immediately picked up by the popular press. Simply
put, there were many who became enthusiasts for the Alvarez
hypothesis:
Indeed, practically the whole world did (become
enthusiasts). Not only did the theory make the cover
of Time, but wonderfully lurid illustrations of doomed
dinosaurs staring dumbly in a sky lit by a vast
fireball appeared on the cover of virtually every
supermarket tabloid and kids' comic book and in every
magazine rack. Popular magazines devoted to science --
such as Omni and Discover -- took it up. Within a mere
historical instant, the notion was in the lay mind as a
fait accompli, an unquestioned given, and not merely a
hypothesis awaiting that normal fate of all scientific
hypotheses -- that is to say, skeptical and reasoned
criticism from other scientists, by which it could be
proven, refined, or dismissed. Even within the realm
of scientific debate, the Alvarez hypothesis did not
follow the normal procedures of science. Dissent was
immediate -- but it went largely unreported, even in
much of the scientific press. Dissenters were in fact
publicly excoriated, even ridiculed, by the
hypothesis's proponents. Rancor seethed in scientific
halls and meetings. This was not the gentlemanly and
collegial debate that usually lies at the heart of
scientific discourse. In the process, a great deal of
very bad scientific thought and procedure occurred --
not just bad behavior. The Alvarez proponents simply
ignored a vast amount of data that other scientists had
patiently collected over the decades and continued to
collect -- evidence that increasingly clearly gainsaid
the new hypothesis.
(p. 4-5)
Face it, the Alvarez hype was popular! As an Australian
journalist, Ian Warden, in the Canberra Times has it:
To connect the dinosaurs, creatures of interest to but
the veriest dullard, with a spectacular event like the
deluge of meteors ... seems a little like one of those
clever plots a publisher might concoct to guarantee
enormous sales. All [the theories] lack is some sex
and the involvement of the Royal Family and the whole
world would be paying attention to them. (p. 4)
But it was only the public mind that was open to the
hypotheses: those who had studied the issue of the K-T extinction
were aware that the theory did not fit the facts. But, even among
scientists, there were those who remained enthusiastic: "Science
magazine became the publication medium of choice for those whose
work supported the Alvarez hypothesis -- although its editors
insist otherwise." (p. 96-97) Koshland, the editor through much
of this period, insisted, in the Chronicle of Higher Education
that: " We've been very careful. We've published arguments from
both sides, and we've published criticism from both sides.
There's no bias.'" Yet, the published record of articles which
appeared in Science belie that claim. As these authors have it:
...(There was a) schism between the public's view of
what was going on and the actual opinions within the
Earth science community. That Science played a role in
creating this schism is unarguable. (p. 103)
The authors, unfortunately, identify the Alvarez hypothesis
with the views of Irving Langmuir regarding pathological science.
This is to say, they see the events of 1980-1996 as "sick"
science, and containing the characteristics of some sort of
aberration in science. To me, the Alvarez hypothesis is not
pathological; it is wrong and it does no good at all to call it
"sick."
I would argue: here is nothing unusual about this sort of
thing. Consider just the parallels mentioned in this book: the
Wegener hypothesis of continental drift (1915-1965) and the
bizarre story of polywater (1966-1974). Here is another case of
"wrong science and its dates are 1980-1995. There is much to
learn from the story: it is a story about science which ain't so
nice. And this is all to the good because the storybook image
of science needs replacing.
