The entire time I was researching and writing Expelled, the Intelligent Design proponents we interviewed kept drawing parallels between the struggle they face from the Darwinian establishment and the challenges faced by climatologists who dare to question whether global warming is real and/or whether human activity has anything to do with it. Denial of grant money, refusal to publish their papers in peer-reviewed journals, denial of tenure and a generally hostile attitude toward the dissenting scientists and their work are just the tip of the iceberg.
Of course, when we made such allegations in Expelled, the Darwinian establishment accused us of being conspiracy theorists, of exaggerating the problem and of outright lying. There's no conspiracy to stifle Intelligent Design. And even if there is such a conspiracy, it's well deserved, because everyone knows that "it is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but we don't like to talk about that)." So if these ID guys are challenging Darwinism, it has nothing to do with science. They're simply out of their gourd, and they deserve to be treated as such.
I don't have the time give a proper response to such distorted depictions of the objections ID proponents are raising--which would involve an extended discussion of how every scientific theory begins with a set of unprovable philosophical assumptions, Thomas Kuhn's Structure of Scientific Revolutions and just for good measure, David Berlinski's The Devil's Delusion: Atheism and its Scientific Pretensions. However, I will say that such thinking contradicts another belief that Darwinists hold to be true in virtually all other cases, namely, that science progresses not through stifling dissent but through encouraging it. Rigorous peer review is supposedly the foundation of good science, essentially creating a self-correcting mechanism whereby if one scientist makes a mistake, his or her peers will be sure to catch it. I've heard many scientists say this process gives science an air of virtual infallibility. If we don't catch the error now, someone will catch it sooner or later.
That's all fine and dandy when everyone is working within the same scientific paradigm or frame of reference. In such cases, no one is asking IF the reigning paradigm--i.e. Darwinism or man-made global warming--is true but merely how and why it's true. But what's to say the paradigm itself is correct? The scientific peers may be holding each other accountable within the system, but who or what is holding the system accountable? After all, if the astrology community made a similar claim--that their research into how the motions of heavenly bodies affect our lives can be trusted because they follow a rigorous peer review system--most people would still write them off as quacks.
Which brings me back to this story, which seems to reveal a systematic attempt to stifle dissent and squelch data that casts doubt on prevailing views about man-made global warming. All along, I said that the dynamic we unearthed in Expelled is not unique to the field of evolutionary biology. All scientific research is a high stakes, highly politicized activity driven by big money and even bigger egos. Scientists stake their personal and institutional credibility on their work, and when someone comes along and questions not only their particular findings but also the theoretical framework upon which they rest, people get a little testy. Which only goes to show that the glowing rhetoric about the merits of peer review as a self-correcting mechanism in science is completely disengaged from reality. Rather than ensure quality, it merely enforces orthodoxy.
This isn't just bad news for dissenting scientists, it's also bad news for the general public, who have been led to believe in a fable called "disinterested scientific inquiry." But as philosopher Daniel Dennett says, "There is no such thing as philosophy-free science; there is only science whose philosophical baggage has yet to be examined." The same can be said for politics, journalism and education. Anyone who thinks differently is naive.
On the other hand, maybe this isn't such bad news, because perhaps next time we won't be so quickly fooled by hucksters in lab coats who try to convince us that the science on a particular matter is "settled." As the late Michael Crichton pointed out, consensus science is like patriotism -- the first refuge of scoundrels:
Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you're being had.
Let's be clear, the work of science has nothing whatever to do with consensus. Consensus the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science, consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.
There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.
Update November 26, 2009: A breaking story out of New Zealand shows that the government's chief climate advisory unit--the National Institute of Water and Atmospheric Research (NIWA)--has allegedly been manipulating data there as well to reflect a warming trend over the past 160 years, to the tune of 0.92ºC per century. The raw data, however, reflects a statistically insignificant 0.06°C per century. An NIWA spokesman said they will issue a press release later today to justify their manipulation of the data.
