I've read many books with a Skeptical slant, and I keep
encountering three particular arguments made by their authors which I
think should be addressed. These arguments are fallacies. They
involve the
suppression and ridicule of historical scientific discoveries.
The three arguments:
- These crackpots think they're right because, they're ridiculed.
- Crackpots' complaints of intellectual suppression are really just
conspiracy theories.
- Crackpots are really just saying that progress doesn't exist.
The three arguments are part of an attack on science
"crackpots." Unfortunately in this case the crackpots are
right and the skeptics are wrong.
1. These crackpots think they're right because they're ridiculed!
A fairly clear version of the first error is illustrated below. I'm not
picking on Dr. Bohren in particular, this same statement is also made by
many other skeptical authors. ( And Bohren's book is excellent, anyone
interested either in physics or science misconceptions should read it! )
Excerpt from
CLOUDS IN A GLASS OF BEER, by Craig F.Bohren (c)1987,
J. Wiley & Sons, Inc.
"The story of Arrhenius could be cast in such a way that he was a hero
and his foot-dragging detractors were villains. I must say, however,
that I am not opposed to scientific conservatism. Indeed, it is
necessary (although when faced with it myself I chafe and writhe and
say bad words.) We forget that many cockeyed ideas that were resisted
by the savants of the day - the Establishment is the pejorative term
used - are often shown to have been - cockeyed. Every now and then a
rare genius turns out to have had a good idea despite initial
resistance to it. And subsequently, hordes of crackpots try to make
capital out of this: Arrhenius was ridiculed, he was right; I am
ridiculed, therefore, I, too, am right. A manifestly faulty syllogism,
but one widely appealed to nevertheless."
Do crackpots really say that they're correct BECAUSE they are persecuted?
Skeptics insist that they do. The skeptics are wrong. I'm a
long-time crackpot myself, so I know better.
<GRIN!>
Since I've encountered the above error more than once, I begin to
wonder whether the skeptical authors can even hear the crackpot
complaints. Can't they hear the various
cautions issued
by "crackpots" against overly-scornful behavior? I certainly hope the
skeptics aren't being consciously dishonest; that they aren't
intentionally using False
Attribution or "Straw Man fallacy" in order to steer attention away from
their opponents' valid points. "Straw man" is a very common debating
strategy used to spread confusion and sway audiences. But
sometimes debaters use it by accident.
Why are the 'skeptic' authors wrong? Let's look at the details. Their
argument with the crackpots starts when, over and over again, particular
skeptical researchers dismiss extraordinary claims without first
inspecting the evidence. They justify their refusal to inspect evidence
in various ways. Here are a few, some made as arguments, others as
unspoken assumptions:
- If a new theory or observation is obviously crazy or impossible,
we should distrust the evidence which supports it. Evidence which
contradicts well known theory is almost certainly wrong, and only VERY
STRONG evidence should be accepted. After all, "Extraordinary claims
require extraordinary evidence."
- Hundreds of scientists hurl ridicule at this theory, and history
shows that the concensus opinion of a large group of scientists is
invariably trustworthy.
- Science only grows, it does not backtrack. Therefore if a new
discovery suggests that modern science has made an extremely major and
unnoticed mistake, and that massive backtracking is required, then that
discovery is wrong.
- Modern science is nearly complete, there are no more gigantic
scientific revolutions possible, so if the new discovery was
real, scientists would already know about it.
- Inspecting the details of a crazy claim is distasteful, and it's
a big waste of time. Crazy claims are always just what they seem, and in
this case we can safely judge a book by its cover, with no need to read
one bit of it.
Their opponents respond fiercely to these arguments/assumptions, pointing
out that
history is full of important discoveries which caught science unawares.
The revolutionary discoveries forced scientists to reappraise
well-explored fields or even to found entirely new scientific fields.
Yet the discoveries were often ridiculed by the experts at the time.
For this reason, the
"crackpots" reject the above four arguments and others like them. They
insist that the scorn of large numbers of experts is not a trustworthy
guide. They
end up saying "After all, the experts laughed at the Wright Brothers too!"
In
response, the skeptics then quote Carl Sagan and assure everyone that,
while They laughed at Galileo, They also laughed at Bozo the clown.
But wait a minute. In these sorts of crackpot-vs-skeptic discussions, I
myself have said "but they laughed at Arrhenius..." yet my statement had
nothing at all to do with Dr. Bohren's quote above. I was not saying that
I'm right because I'm ridiculed! The skeptics are
misinterpreting the response of the offbeat researchers. They hear
this: "I am ridiculed, therefore I am correct!" But this interpretation
is wrong. This was mis-heard. It is not what the unorthodox researchers
are trying to say.
The Crackpots' mention of the Wrights, Arrhenius, Galileo, etc., was meant
to address an entirely different point. Here it is:
Although the crazy ideas usually prove to be just that,
every so often they do prove to be correct. They even occasionally
prove to have immense value. They trigger scientific revolutions.
Therefore "crazy" ideas must never be
automatically dismissed out of hand without first inspecting their
supporting evidence. If we ridicule crazy ideas without giving them a
fair hearing first, sooner or later we'll ridicule the next Galileo.
It's a bad practice to use sneering and ridicule to block unconventional
ideas. It's a very bad idea to erect near-insurmountable barriers against
all seemingly irrational ideas, because doing so will discard the
occasional Galileos and Arrheniuses along with the large hoards of
crackpots. Or in other words, never ridicule things which you've
haven't even bothered to investigate.
Some Skeptics would prefer that the apparent crackpots always prove to be
just that: crackpots. But the reality is not so simple. If we fight too
hard to eliminate the "weird" stuff, then we run the risk of suppressing
the next Copernicus. I say it this way: There are diamonds hidden in the
sewage. Those who make it their job to keep Science entirely and totally
"clean" will also become the newest generation of scoffing debunkers who
fight to prevent the next group of genuine, disruptive, revolutionary
advances.
The history of new ideas proves this by example. Any inspection of
science history will reveal a long list of genuine discoveries which were
treated with hostile prejudice. If skeptical people ignore such powerful
evidence presented by "the crackpots," and if they instead distort the
historical examples and proclaim them to be a simple logical error, then
it is the skeptics who make the logical error, not the crackpots.
When a crackpot drags out the old "They Laughed at the Wright Brothers"
argument, that person is not stating that ongoing ridicule proves
crackpot ideas must be correct. Instead that person is simply saying
this:
"You who make a policy of automatically rejecting 'crazy' ideas without
first giving them a fair hearing, you would have joined the experts in
1905 who refused to view the Wright Flyer in action, and whose
continuing public ridicule eventually forced the Wrights to abandon the
USA and move to France."
And to the great shame of scientists everywhere, the charge often has
merit.
"Theories have four stages of acceptance:
i) this is worthless nonsense;
ii) this is an interesting, but perverse, point of view.
iii) this is true but quite unimportant.
iv) I always said so."
- J.B.S. Haldane, 1963
"All great truths began as blasphemies" - George Bernard Shaw
2. Crackpots' complaints of intellectual suppression are really just
conspiracy theories!
I've encountered another common misinterpretation of 'They Laughed At The Wright
Brothers.' This is from sci.physics FAQ. The
"laughing" in this case is at Galileo...
sci.physics FAQ, section 1.7 (7/97)
People putting forward extraordinary claims often refer to Galileo as
an example of a great genius being persecuted by the establishment for
heretical theories. They claim that the scientific establishment is
afraid of being proved wrong, and hence is trying to suppress the
truth. This is a classic conspiracy theory. The Conspirators are all
those scientists who have bothered to point out flaws in the claims put
forward by the researchers.
Again the Skeptics are making a large (and perhaps too convenient)
misinterpretation. As before, things start out when "crackpots" claim to
have made discoveries. Rather than carefully inspecting the evidence,
instead the skeptics dismiss the unorthodox research out of hand. The
crackpots object fiercely to such treatment. Then the skeptics ignore the
complaints because they change them into invalid complaints called
"conspiracy theories."
Skeptics should do their opponents the courtesy of actually listening to
their opponents objections. When a crackpot complains that the scientific
peer group is attempting to suppress his/her work, we should carefully
examine the complaint. Does the researcher actually claim to be
the target of an organized conspiracy? If not, then to state otherwise is
indulging in a "straw man" argument. After all, dissenters in any group
are often suppressed by majority opinion, and such "intellectual
suppression" has nothing to do with organized conspiracies.
Think about it. It makes sense that if a significant portion of
individual scientists really are afraid of being proved massively
wrong, if most scientists really do have emotional investment in a
current worldview... then a certain portion of the "scientific
establishment" really will tend to indulge in suppressive acts.
The history of science reveals that this has happened time and again
(recall Galileo, Wright Bros., Plate Tektonics, Chandrasekar's black holes
in 1930, jumping genes, Krebs cycle, etc.) Anyone who thinks these
suppression events don't happen is simply ignorant of science history.
See:
Ridiculed Geniuses
http://amasci.com/weird/vindac.html
Suppression of dissenting voices has nothing to do with conspiracies. Just
as no conspiracy is needed to explain intolerance (racism or sexism,) no
conspiracy is needed to explain intellectual suppression. All we require
is that a collection of individual attackers have a common motivation.
If the victim of genuine suppressive acts makes a complaint, then it would
be a great injustice to dismiss their complaint as simple paranoia.
Analogy: if women complain about receiving lower salaries then men, should
we dismiss them as Conspiracy Theorists?!! Obviously not. As the old
saying goes, you aren't paranoid if a group of people really is out
to get you. And a group can be out to get you even if the group doesn't
organize or conspire. In other words:
COMPLAINTS OF INTELLECTUAL SUPPRESSION ARE VERY DIFFERENT THAN CONSPIRACY
THEORIES.
In addition, those who claim that suppression doesn't exist by (claiming
it's
just conspiracy theories) demonstrate their ignorance of the
workings of science.
After all, one main role of peer review is to suppress science!
It's supposed to suppress the bad, incompetent, misguided science.
Intellectual
suppression is built into modern science as a corrective mechanism. It's
hardly a "conspiracy." And
peer review isn't the only way that misguided research is suppresed.
It's also suppressed when the scientific community simply ignores it, or
when a few zealous scientists attack it actively.
This
sort of "suppression" is common and perfectly normal, and has nothing to
do
with conspiracy theories. Suppression becomes a very serious problem when
the the suppression itself is misguided; when revolutionary discoveries
are rejected for publication and when research grants are denied.
I see the above sci.physics FAQ entry as being dangerous. It promotes a
view where anyone who complains of scientific suppression is nothing but a
delusional paranoid. The entry is implying that intellectual bigotry
cannot occur. It says that complaints of mistreatment are invalid BY
DEFINITION. It justifies the following common ploy of many skeptics:
"ridicule first, no need to ask questions later, since those who complain
of widespread ridicule are obviously delusional."
While it's true that large numbers of crackpots do exist, with many of
these genuinely suffering from delusions of persecution, it's also true
that suppression
of minority opinions exists in science. Kuhnian revolutions or "paradigm
shifts" are probably caused by this suppression. After all, scientists
are human, and if
we did not find particular "paradigms" so useful, and cling to them so
fiercely, then science
might progress more smoothly and never require any periodic revolutions.
Also, scientific discoveries sometimes threaten powerful interests (e.g.
when popular pesticides are shown to be harmful, etc.), and in those
cases, attempted suppression is very real.
There is also a less honorable
example...
When human beings encounter ideas which threaten their fundamental
worldviews, the typical response is to thoughtlessly and instantly crush
the new ideas; to
eliminate them. The searing discomfort engendered by new ideas is called
"Cognitive
Dissonance." The feeling is almost painful, and it's even more painful
for scientists whose salaries or sometimes their very careers depend on
correct mental models. When we
feel this type of pain, most of us will take immediate steps to stop it.
Researchers are not immune to this, although the historical evidence is so
shameful that it is not widely acknowledged outside the fields of Science
History/Sociology. Professional scientists who pursue unpopular research
tend to encounter not only the expected passive disbelief and dismissal.
They also suffer active suppression: ridicule, loss of funding (even loss
of funding for their conventional work,) attempts to revoke honors,
and myriad subtle attacks by colleagues, with the attacks often performed
behind the scenes. In fact, one common attack is exactly the one above.
It goes like this:
"Scientists never attack each other, so if you think colleagues are trying
to hurt your career, you must have mental problems and therefore need
professional help."
And so, when someone complains about scientific suppression, we must never
automatically dismiss them as conspiracy-theorists. Instead we should
take an unbiased view of the evidence. Yes, in many cases we will find
that the hated "suppressors" are simply the thoughtful skeptics who are
debunking some pseudoscience beliefs. But in a few rare cases we'll find
that the "supressors" are scientists whose entire world would be turned
upside-down by any evidence which supports the new ideas. These
scientists are individually taking action to silence those who
bring forth that evidence.
When someone says "They laughed at Galileo", we must take care not to
automatically assume paranoia on their part. We should instead hear it as
a plea to examine their evidence, just as Galileo pleaded with his
contemporaries. Remember, it was not the religious authorities who
ignored Galileo's evidence. Instead it was his fellow scientists who
refused to actually come and look through that darned telescope!
3. Crackpots are really just saying that progress doesn't exist
Some skeptics often use a third straw man argument to justify their
refusal to inspect evidence. When a maverick researcher objects to their
confident ridicule, the skeptics respond with this 1989 quote from Isaac
Asimov:
"When people thought the earth was flat, they were wrong. When people
thought the earth was spherical, they were wrong. But if you think that
thinking the earth is spherical is just as wrong as thinking the earth is
flat, then your view is wronger than both of them put together."
In other words, anyone who says "They Laughed at the Wright Brothers" is
not pointing out the errors of skepticism. Instead they are really just
saying that science doesn't make progress. After all, today's scientists
are different than scientists of old. Today they're far too advanced to
make such enormous blunders.
Oh, really?
It's very convenient that skeptics chose the roundness of the
earth
to illustrate how today's scientists are too advanced to make mistakes.
Better they should learn the history of biology, where transposable genes
were ridiculed for decades before the recent acceptance, and where the
experts
were blind to the symbiotic nature of mitochondria and chloroplasts until
very recently.
Yes, our knowledge of Earth's roundness is close to 100% complete. But is
this really a good model for science as a whole? History contains other
examples. The most famous even involves the surface of the
Earth. If we understand Earth so well, why was Plate Tektonics ridiculed
as crackpotism for thirty years until geologists finally started taking it
seriously in the 1960s? The example of the Earth should tell us to take
care before hurling ridicule, since supposed experts might know far less
about the world than they imagine.
Asimov's quote is possibly dangerous to the more creative scientists. It
subtly suggests that they must abandon revolutionary discoveries because
science is complete and has no room for such things anymore. It implies
that the most important workings of the world are all discovered, so
everyone should stop studying it. But this is nuts. Major discoveries
even today are forcing scientists to reexamine everything they thought
they understood about cosmology. Suppose something similar occurred with
a fringe research topic, e.g. human minds and PSI phenomena. If "psychic
powers" are ever proved valid, then such an event won't be unique. It
will simply join the long list of other disruptive revolutions which
deflate scientists' hubris and push their understanding of the world ahead
too suddenly for their own comfort.
One final note. They "laughed" at Galileo, but they DIDN'T laugh at Bozo
the Clown, not really. Examine the quote carefully, since it contains a
subtle twist. By "laughed" in the first sense, we mean "they used
mockery to
suppress a dissenting voice." By "laughed" in the second sense, we mean
"they found Bozo funny."
It seems that even Sagan's quote about Bozo the Clown is yet another straw
man argument: it hides the fact that the main topic of the quote is about
fighting against new ideas with scornful guffaws and amused contempt.
There was no scorn or contempt directed at Bozo. The quote is dishonest.
It is not about healthy laughter at all.
