Jonathan Newman of The Mises Institute On Neil deGrasse Tyson And Science
See
Neil Ty, The Scientism Guy.
"Neil deGrasse Tyson has released a new video
aimed at a what he sees as a growing anti-intellectualism problem in
the United States. It was released at the same time as the March for
Science and many Earth Day demonstrations. He reflects on what he thinks
made America great and what’s stalling progress today. Science used to
be respected, but today, there is a growing crowd of science-deniers who
threaten our “informed democracy.”
The real anti-intellectual
move, however, is conflating science, the scientific method, and truth
to be one and the same. Fundamentally, science is any human attempt at
discovering truth. What is true exists independently from what humans
believe to be true or how humans arrive at truth claims. The scientific
method, the process of using repeated experiments in an attempt to
validate or falsify the conclusions of previous experiments, is but one
way humans attempt to discover truth.
The purpose of the video was
to call out the obstinate, ignorant voters who deny what many regard as
certain truths handed to them by a body of elite, trustworthy
scientists. Yet Tyson and the marchers border on an equally dangerous
view: scientism.
Scientism isn’t scientific
Scientism
is the over-reliance on or over-application of the scientific method.
Scientism has many forms, one of which is the use of empirical methods
to do economic science, or the dismissal of claims not based on
experiment results that question other claims that are based on
experiment results. Mises dealt with scientism repeatedly, and closely guarded the boundary between economics and other sciences.
The
scientific method is not universally appropriate. Consider an extreme
case: if you measured a few right triangles and observed that the sides
did not correspond to what the Pythagorean theorem says, would you toss
the Pythagorean theorem, or would you reexamine your measurement method?
Would you dismiss the logical geometric relation in favor of the
scientific method?
The scientific method is particularly suited
for the natural sciences. It’s hard to recommend a different method than
experimentation and observation to answer questions about chemical
reactions, astrophysics, quantum mechanics, and biology.
The
scientific method is unnecessary or even ill-suited in other areas,
however. Consider these questions, and what sort of approach is
appropriate to answer them: What is 17 divided by 3? All else held
equal, what are the effects of an increase in demand for blue jeans? Who
should I invite to my party? What are the effects of expansionary
monetary policy on employment, prices, incomes, production, consumption,
and borrowing? How should I treat people?
Of course, Neil
deGrasse Tyson wouldn’t recommend using the scientific method to answer
all of these questions (hopefully), but the point is that empiricism and
experimentation are limited in their appropriate applications. The
scientific method does not have a monopoly on truth.
Always open to falsification
The
scientific method has another large limitation: conclusions derived
solely by experimentation are always susceptible to falsification by
just one aberrant observation. For this reason and others, even wide
consensus among scientists should be met with at least some skepticism
before the heavy hand of the government gets involved.
In 1992,
the government, backed by the scientific community, told you that you
needed 6-11 daily servings of bread, cereal, rice, and/or pasta to
maintain good nutrition (and that saturated and animal fats are to be
avoided). Many government policies and public school food offerings were
based on this recommendation, including, suspiciously, agricultural
subsidies and import tariffs. But then, years later, new information
revealed this to be terrible advice, after a big jump in diabetes diagnoses and obesity rates.
Or, consider the government’s attempts at alleviating malaria. The National Malaria Eradication Program sprayed DDT in 4,650,000 homes and overhead by aircraft.
Later, it was realized that DDT is carcinogenic and the spraying had a
severe effect on the environment and wildlife, birds in particular. Birds
of prey like the bald eagle are not considered endangered species
anymore, and the ban on DDT is considered a major factor in their
recovery. Even this conclusion is in question, including whether or
not DDT is carcinogenic for humans, but the point is that the government
itself backtracked on its own science-based solution to a problem. It
banned a chemical it once sprayed indiscriminately.
Since the climate is such an important issue for Tyson, consider also the claims and predictions of various scientists around 1970.
Earth Day had just started, and scientists were predicting rather
apocalyptic scenarios, similar to what we are hearing today from climate
scientists. To be clear, just because these predictions turned out to
be “spectacularly wrong”, it doesn’t necessarily mean that modern claims
are wrong. But it might explain a lot about the modern layperson’s
skepticism, as opposed to sheer stupidity as Tyson suggests.
Sites like retractionwatch.com
document the increasingly frequent cases in which academic journals
must retract published research because the peer review process was a
sham or when other fraudulent activity comes to light. A recent entry reports
that Springer had to retract 107 papers on cancer due to fake peer
reviews. Surprisingly, retraction doesn’t always mean fewer citations,
as this top 10 list of most highly cited retracted papers demonstrates.
Skepticism and science are good friends
These
examples reveal another larger issue with Tyson’s argument. Tyson says,
“every minute one is in denial, you are delaying the political
solution.” The problem is that sometimes delays and denial are exactly
what is needed. The scientific method requires time and attempts at
falsification.
There is an inherent contradiction and arrogance in
Tyson’s video. In one breath he is praising science and the way the
scientific method works: “I get a result. A rival of mine double checks
it, because they think I might be wrong.” But in the next breath, he
declares to the doubter who also thinks some scientific conclusion might
be wrong: “You don’t have that option! When you have an established,
scientific emergent truth, it is true whether or not you believe in it.”
So
the rival scientist is allowed to question the conclusions of other
scientists because the conclusions might not be true, but nobody else
is. We may not all be equipped with a laboratory, but we are all
equipped with reason, experience, preferences, common sense (some more
than others), gut instincts, some ideas about what is morally right and
what is morally wrong, and our own areas of expertise. Surely these are
not meaningless when it comes to judging the claims of a
politically-connected technocratic elite and their policy
recommendations.
Political connections bias science
Like
the food pyramid, political interference in the scientific process led
to terrible consequences in scheduling various drugs. Marijuana, which
is now widely accepted to be virtually harmless, is still scheduled with
heroin and ecstasy, and higher than cocaine and methamphetamines. Yet researchers and agencies
produced enough of Tyson’s “emergent truths” (which we are not to
doubt) over the years to keep it that way. The effects of this prohibition
have been devastating, including a prison system bursting at the seams,
militarized local police, violent organized crime (legal and illegal),
and more deaths than marijuana itself could ever cause on its own.
Indeed,
when the government does or funds research, it seems to always arrive
at the conclusions which involve the government getting larger in size
and scope. To question these expansions is to question the science, and
to question the science is to mark oneself a stubborn idiot.
Tyson
is trying to convince these stubborn idiots to learn some science. Only
then, he says, will they become the informed citizens this democracy
needs. But what if the skeptics aren’t stupid? What if their skepticism
is due to the perceived track record of the scientific community over
the years (especially when the government is in the mix)?
Most of
what Tyson perceives as anti-intellectualism may not be a problem with
people's ability to think, but an inability to trust a
politically-connected scientific community that has led them astray in
the past. Besides, if he really thinks too many Americans are too
stupid, then he ought to look no further than the public education
system that produced this alleged mass of illiterate science-deniers.
Name-calling over debate
But
I don’t think Tyson views the American electorate as 51% dumb and 49%
smart. I think he knows that there are a few outliers with truly
unscientific ideas and who will not be convinced of even the most
obviously true scientific conclusions.
The implication in the
video is that if you don’t go along with this one idea, you are just
like those wacky outliers. Those who have a healthy skepticism of what
the government and the intelligentsia claim are lumped together with the
outliers as a rhetorical strategy.
In practice, however, even
those who are on board with the science but disagree with the government
solution to the problem, are also added to the same group of idiots.
It’s
a rhetorical strategy that may not work for him. Having been in my fair
share of debates, I know that insulting my opponents isn’t the best way
to have them see things from my point of view.
Suppose I come across a
minimum wage proponent. Should I call them an ignorant
economic-theory-denier, or should I just keep trying to convince them of
the effects of minimum wage legislation? Should I treat them the same
way I might treat somebody who holds to the completely debunked labor
theory of value or somebody who thinks the economy is subject to the
whims of lizard-people?
The end goal: bigger government
At
the end of the video, Tyson’s real interest becomes apparent. He wants
the government to battle with the climate, stick everybody with the same
vaccinations, and teach every student a materialistic explanation for
the origins of the universe and human and animal life.
Tyson
implies that scientific conclusions give way to political solutions,
when often what is best is to simply inform the people of some new
"emergent truth" and allow individuals and firms to change their
behavior in light of and to the extent that they buy in. Top-down,
universally enforced "solutions" often cause more problems than they
solve and don't have the flexibility, effectiveness, or economic
viability that they need.
In the beginning of the video, Tyson
asks, “How did America rise up from a backwoods country to be one of the
greatest nations the world has ever known?” I would argue that the
impressive accomplishments of the United States are in spite of and not
because of government intervention. The economic development of the
United States is due to a wide range of factors, including an early
adherence to relatively laissez-faire economic policy, the industrial
revolution, only the occasional war instead of the state of perpetual
war we find ourselves in today, a relatively individualistic culture, an
“entrepreneurial spirit”, and abundant natural resources and farmable
land.
Certainly scientific and technological innovations played a
major role. But my questions for Neil deGrasse Tyson are these: what
made those scientific and technological innovations possible? Do you
want Americans to be more scientifically literate as an end or as a
means to establishing a political agenda? Does the government really
need to get involved for us to solve all of our problems? What harm is
there in further experimentation and further attempts at convincing the
population of your ideas before resorting to silencing the unconvinced
by labeling them “science deniers”?
Telling people not to question
their government or a politically-connected scientist-class is
dangerous. It’s throwing the baby out with the bath water, and it seems
to run against his own values. Indeed, Neil deGrasse Tyson is frequently
featured on a popular YouTube channel called “Question Everything”. We should encourage a healthy skepticism, especially when the government is involved.
When
it comes to political solutions to Tyson’s list of problems, it means
scarce resources must be employed toward some goal. This puts him
outside of his jurisdiction, natural science, and into my jurisdiction,
economics. Dare I tell him to not question my conclusions?"
