As seen here, the ID movement has developed a diverse research program bearing fruit in the form of more than 50 peer-reviewed scientific papers. Beyond doubt, ID proponents have published a significant body of legitimate peer-reviewed research.
In the past, critics charged that ID cannot be taken seriously until it has published just such "peer-reviewed research." Yet it's important to understand that being recognized in the peer-reviewed literature is not an absolute requirement to demonstrate an idea's scientific merit.
Good Science without Peer-Review
Some of the most important and groundbreaking work in the history of science first appeared in published form not in peer-reviewed scientific journal articles but in scientific books. That includes Copernicus' De Revolutionibus and Newton's Principia. Einstein's original paper on relativity was published in a scientific journal (Annalen der Physik), but did not undergo formal peer-review.1 Indeed, Darwin's own theory of evolution was first published in a book for a general and scientific audience -- his Origin of Species -- not in a peer-reviewed paper.
Moreover, important scientific work has not uncommonly been initially rejected by peer-reviewed journals. As a 2001 article in Science observed, "Mention 'peer review' and almost every scientist will regale you with stories about referees submitting nasty comments, sitting on a manuscript forever, or rejecting a paper only to repeat the study and steal the glory."2 Indeed, an article in the journal Science Communication by Juan Miguel Campanario notes that top journals such as "Science and Nature have also sometimes rejected significant papers," and in fact "Nature has even rejected work that eventually earned the Nobel Prize."3 In an amusing letter titled "Not in our Nature," Campanario reminds the journal of four examples where it rejected significant papers:
(1) In 1981, Nature rejected a paper by the British biochemist Robert H. Michell on signalling reaction by hormones. This paper has since been cited more than 1,800 times.Elsewhere, Campanario lists "instances in which 36 future Nobel Laureates encountered resistance on the part of scientific journal editors or referees to manuscripts that dealt with discoveries that on later dates would assure them the Nobel Prize."5 Likewise, Tulane University physicist Frank Tipler offers the following anecdotes:
In light of these kinds of examples, Campanario concludes:
Something is wrong with the peer review system when an expert considers that a manuscript is not of enough interest and it later becomes a classic in its discipline (or, even worse, when the work reported in a rejected paper earns the Nobel Prize). ... Contrary to reports by the American Association for the Advancement of Science and the National Academy of Sciences, publication in a peer-reviewed journal is not necessarily the best means of identifying valid research.7The Supreme Court Agrees
Even the U.S. Supreme Court has recognized that good science will not always be published in a peer-reviewed journal. In the landmark 1993 case Daubert v. Merrell Dow Pharmaceuticals, Inc., the Court observed that while publication in peer-reviewed journals can be an indicator of legitimate science, it is not necessarily an indicator of good science:
Publication (which is but one element of peer review) is not a sine qua non of admissibility; it does not necessarily correlate with reliability, and in some instances well-grounded but innovative theories will not have been published. Some propositions, moreover, are too particular, too new, or of too limited interest to be published.8While the Court noted that "submission to the scrutiny of the scientific community is a component of 'good science,'" it ultimately held that "publication (or lack thereof) in a peer reviewed journal" is merely "a relevant, though not dispositive, consideration in assessing the scientific validity" of a claim.9
The point that scientific progress depends upon considering minority views and unpopular ideas that may not have been published in peer-reviewed journals was made emphatically and eloquently by Stephen Jay Gould, writing with other scientists and historians of science, in an amicus brief submitted to the Supreme Court regarding the Daubert case:
Judgments based on scientific evidence, whether made in a laboratory or a courtroom, are undermined by a categorical refusal even to consider research or views that contradict someone's notion of the prevailing "consensus" of scientific opinion. Science progresses as much or more by the replacement of old views as by the gradual accumulation of incremental knowledge. Automatically rejecting dissenting views that challenge the conventional wisdom is a dangerous fallacy, for almost every generally accepted view was once deemed eccentric or heretical. Perpetuating the reign of a supposed scientific orthodoxy in this way, whether in a research laboratory or in a courtroom, is profoundly inimical to the search for truth. A categorical refusal even to examine and consider scientific evidence that conflicts with some ill-defined notion of majority opinion is a recipe for error in any forum.Thus, there are many compelling arguments from both the theory and practice of the scientific enterprise that demonstrate peer-review is not an absolute requirement of good science.
The Peer-Review System Under Attack
Arguments against peer-review generally come in two forms: (1) that the system wrongly rejects scientifically valid papers, and (2) that the system wrongly accepts scientifically flawed papers. A 2008 paper in the Financial Times summarized these dual criticisms:
[T]he process is under assault from critics who say it is ineffective at filtering out poor research, while it perpetuates predictable work at the expense of more imaginative thinking. In the long run we all suffer, argues Don Braben of University College London, because economic growth depends on unpredictable scientific advances.11Similarly, in 2006 journalist and medical doctor Lawrence K. Altman wrote in the The New York Times that the peer-reviewed system has been severely weakened by allowing the publication of flawed or even fraudulent studies:
Recent disclosures of fraudulent or flawed studies in medical and scientific journals have called into question as never before the merits of their peer-review system. ... Virtually every major scientific and medical journal has been humbled recently by publishing findings that are later discredited. The flurry of episodes has led many people to ask why authors, editors and independent expert reviewers all failed to detect the problems before publication.12Likewise Richard Smith, former editor of the British Medical Journal, comments that peer review is "very slow, expensive, a considerable lottery, completely hopeless at detecting errors and fraud, and there's evidence of bias."13 Indeed, a 2001 article in Science reported that in one study, "researchers found little evidence that peer review actually improves the quality of research papers."14
As a result of such criticisms, a 2012 article in the New York Times noted that scientists are becoming increasingly skeptical of the peer-review process:
For centuries, this is how science has operated -- through research done in private, then submitted to science and medical journals to be reviewed by peers and published for the benefit of other researchers and the public at large. But to many scientists, the longevity of that process is nothing to celebrate.A 2011 article by David Colquhoun, Professor of Pharmacology at University College in London also argues that the peer-review system "doesn't work very well any more, mainly as a result of the enormous number of papers that are being published (an estimated 1.3 million papers in 23,750 journals in 2006)."16 In Colquhoun's view, "There simply aren't enough competent people to do the job" of reviewing papers, and thus "Any paper, however bad, can now get published in a journal that claims to be peer-reviewed."17 Complicit in this problem, Colquhoun says, is the "publish-or-perish culture":
The blame for this sad situation lies with the people who have imposed a publish-or-perish culture, namely research funders and senior people in universities. To have "written" 800 papers is regarded as something to boast about rather than being rather shameful. University PR departments encourage exaggerated claims, and hard-pressed authors go along with them.18The Myth of the Objective Expert
Despite these criticisms, non-experts often mistakenly believe that individual scientists who serve as editors or referees on papers are always open-minded and completely objective in reviewing papers. According to this naÔve assumption, peer-review is a flawless gold-standard which guarantees the legitimacy of a paper. Stephen Jay Gould sought to dispel these myths when he observed that "[t]he stereotype of a fully rational and objective 'scientific method,' with individual scientists as logical and interchangeable robots, is self-serving mythology."19 Likewise, Lawrence Altman's article in the New York Times explains:
Many nonscientists perceive reviewers to be impartial. But the reviewers, called independent experts, in fact are often competitors of the authors of the papers they scrutinize, raising potential conflicts of interest.20Unfortunately, public perceptions of perfectly "objective" and "impartial" reviewers are reinforced by some who wield "peer-review" as a political tool to shut down minority dissenting views. According to Altman, many have overstated the integrity of the peer-review process, thus "creat[ing] a widespread misimpression that passing peer review is the scientific equivalent of the Good Housekeeping seal of approval."21 He continues that in reality, the canonization of the peer-review process amounts to a power-grab by scientific journals:
By promoting the sanctity of peer review and using it to justify a number of their actions in recent years, journals have added to their enormous power.22Altman paints a disturbing picture of the peer-review system, where journals have huge economic interests in preserving the current flawed system, and research scientists gladly play along because peer-reviewed papers are necessary for them to maintain their positions:
Despite its flaws, scientists favor the system in part because they need to publish or perish. The institutions where the scientists work and the private and government agencies that pay for their grants seek publicity in their eagerness to show financial backers results for their efforts.Given this lack of perfect objectivity, another major problem with the peer-review system is its non-double-blind nature. When articles are sent out for review, the reviewers often (though not always) are told who authored the paper they are reviewing. And if they aren't told, they often can figure it out simply by being aware of who is working on what projects within the field. Reviewers who perceive the authors as competitors or enemies might be biased against the paper, and more likely to reject the work even if it has merit. Reviewers who perceive the authors as allies or friends are more likely to accept the work, even if it has weaknesses. Given the pressure on everyone to "publish or perish," reviewers may feel tempted to approve papers for publication, hoping that when they want their own papers published, others in the field will do the same for them.
Political concerns, economic factors, lab-rivalry, support for one's friends, and other normal human elements are never completely divorced from the peer-review process.
Playing the "Peer-Review" Card to Shut Down Dissent
Despite the deficiencies in the peer-review system, "peer-review" is increasingly used as a rhetorical weapon, enlisted for the purpose of silencing dissenting, minority scientific viewpoints. University of Kent sociologist Frank Furedi has explained the alarming rise of what he calls "advocacy science," which defends itself not by citing data but by advocating the myth of infallible peer-review:
[I]n recent years the most disturbing threat to the integrity of the peer-review system has been the growing influence of advocacy science. In numerous areas, most notably in climate science, research has become a cause and is increasingly both politicized and moralized. Consequently, in climate research, peer review is sometimes looked upon as a moral project, where decisions are influenced not simply by science but by a higher cause.24Furedi believes that peer-review is wielded as a political weapon:
Increasingly, peer review is cited as kind of unquestioned and unquestionable authority for settling what are in fact political disputes. Consequently, the findings of peer review are looked upon, not simply as statements about the quality of research or of a scientific finding, but as the foundation for far-reaching policies that affect everything from the global economy to our individual lifestyles.
A revealing anecdote of those who play the "peer review" card to shut down dissent comes from the debate over claims made by NASA scientists in 2010 that they had discovered arsenic-based life. The controversy began when the NASA scientists announced their findings in a press conference where they promised, through much media hype, to reveal "an astrobiology finding that will impact the search for evidence of extraterrestrial life." As we discussed here, their claims were critiqued by many scientists.
Initially, those criticisms came in the form of non-peer-reviewed rebuttals posted on the Internet or made in interviews for news articles. The NASA scientists who had made the claims of arsenic-based life refused to respond to those criticisms other than making comments like "we hope to see this work published in a peer-reviewed journal, as this is how science best proceeds."
Evolutionary biologist Jonathan A. Eisen recently wrote a post titled "Stop deifying 'peer review' of journal publications," calling out the hypocrisy of those NASA scientists. In short, they hyped their claims in the media -- and thus promoted their views outside of the peer-reviewed literature -- but then refused to answer critics who hadn't published rebuttals in the peer reviewed literature. Eisen wrote the following about the refusal of the NASA scientists to address the criticisms:
This was amazing since, well, they were the ones who held the overhyped press conference. And then I (and others) found it appalling that they in essence would not response to critiques because they were not "peer reviewed." ... Whether they were right or not in their claims, they are now hypocritical if they say that the only response should be in the scientific literature.Eventually the critics did publish their rebuttals in the peer-reviewed literature (we also covered the peer-reviewed responses here). But this episode reveals the hypocrisy of those push their views upon the public through non-peer reviewed venues like the media, but then try to shut down critics for responding in non-peer-reviewed venues.
But is it always feasible for those who dissent from the majority viewpoint to gain access to publication in peer-reviewed journals?
On Scientific Bias, Lessons from the History of Science
Historians of science understand perfectly well why minority scientific viewpoints have difficulty being published in peer-reviewed scientific papers. A paper in the Journal of the American Society for Information Science observes that scientists can be biased against accepting new ideas:
Sometimes scientists encounter strong resistance from peers to their new ideas. The scientific community often finds it difficult to accept new ideas or methods and unexpected observations. The greatest and most harmful source of resistance from scientists to scientific discovery comes precisely from those peers whose mission is to preserve the quality of scientific work: The editors and referees of scientific journals.26Similarly, the famous historian of science Thomas Kuhn wrote in his seminal book The Structure of Scientific Revolutions:
No part of the aim of normal science is to call forth new sorts of phenomena; indeed those that will not fit the box are often not seen at all. Nor do scientists normally aim to invent new theories, and they are often intolerant of those invented by others.27As a new scientific theory that challenges much conventional wisdom, intelligent design faces this very type of intolerance. In one case, pro-ID biochemist Michael Behe submitted an article for publication in a scientific journal but was told it could not be published because "your unorthodox theory would have to displace something that would be extending the current paradigm."28 Behe concluded:
The take-home lesson I have learned is that, while some science journal editors are individually tolerant and will entertain thoughts of publishing challenges to current views, when a group (such as the editorial board) gets together, orthodoxy prevails.29Science journalist Denyse O'Leary agrees, writing that "The overwhelming flaw in the traditional peer review system is that it listed so heavily toward consensus that it showed little tolerance for genuinely new findings and interpretations."30 In Frank Tipler's view, intelligent design theory faces such knee-jerk intolerance:
It is impossible to get any member of the National Academy of Sciences to consider it seriously. The typical reaction of such scientists is to foam at the mouth when the phrase "intelligent design" is mentioned. I have recently experienced this. In the fall of 2002, I arranged for Bill Dembski to come to Tulane to debate a Darwinian on the Tulane faculty. (This faculty member was appropriately named Steve Darwin!) Bill presented only the evidence against Darwinism in the debate, while Steve's response unfortunately had quite a few ad hominem remarks. Steve has continued to be friendly to me personally. But ever since the Dembski/Darwin debate, another evolutionist on the Tulane faculty -- who shall remain nameless! -- glares at me every time he sees me. Before the debate he and I were friends. Now he considers me a monster of moral depravity.Indeed, some of the most prominent scientific journals have all-but declared that they would never publish an ID-friendly paper. In 2002, the American Association for the Advancement of Science (AAAS), which publishes Science, issued an official declaration that "the ID movement has failed to offer credible scientific evidence."32 But when some of the AAAS board members were surveyed, it was found that they voted to declare "intelligent design as unscientific without actually reading for themselves the academic books and articles by scientists proposing the theory."33 Evidently, when it comes to intelligent design, politics rather than science drives the behavior of many journals.
Despite the attempted lockout, ID proponents have published their ideas in peer-reviewed scientific journals. This shows that ID has academic legitimacy whether or not one applies the dubious "peer-review" test of good science.
