The belief that science and religion (and science and politics for that matter) are exact opposites is one of the most tenacious and misguided viewpoints held by Americans today, one that is unfortunately reinforced by many science journalists. Science is not at all faith-based, claims Forbes contributor Ethan Siegel in his rebuke of Matt Emerson’s suggestion otherwise. In arguing against the role of faith in science, however, Siegel ironically embraces a faith-based view of science. His perspective is faith-based not because it has ties to organized religion, obviously, but rather because it is rooted in an idealization of science disconnected from the actual evidence on scientific practice. Siegel mythologizes scientists, seeing them as impersonal and unbiased arbiters of truth. Similar to any other thought-impairing fundamentalism, the faith-based view of science, if too widespread, is antithetical to the practice of democracy.
Individual scientists, being human, fall prey to innumerable biases, conflicts of interest, motivated reasoning and other forms of impaired inquiry. It sanctifies them to expect otherwise. Drug research, for instance, is a tangled thicket of financial conflicts of interest, wherein some scientists go to bat for pharmaceutical companies in order to prevent generics from coming to market and put their names on articles ghost-written by corporations. Some have wondered if scientific medical studies can be trusted, given that many, if not most, are so poorly designed.
Siegel, of course, would likely respond that the above cases are simply pathological cases science, which will hopefully be eventually excised from the institution of science as if they were a malignant growths. He consistently tempers his assertions with an appeal to what a “good scientist” would do: “There [is no] such a thing as a good scientist who won’t revise their beliefs in the face of new evidence” claims Siegel. Rather go the easy route and simply charge him with committing a No True Scotsman fallacy, given that many otherwise good scientists often appear to hold onto their beliefs despite new evidence, it is better to question whether his understanding of “good” science stands up to close scrutiny.
The image of scientists as disinterested and impersonal arbiters of truth, immediately at the ready to adjust their beliefs in response to new evidence, is not only at odds with the last fifty years of the philosophy and social study of science, it also conflicts with what scientists themselves will say about “good science.” In Ian Mitroff’s classic study of Apollo program scientists investigating the moon and its origins, one interviewed scientist derided what Siegel presents as good science as a “fairy tale,” noting that most of his colleagues did not impersonally sift through evidence but looked explicitly for what would support their views. Far from seeing it as pathological, however, one interviewee stated “bias has a role in science and serves it well.” Mitroff’s scientists argued that ideally disinterested scientists would fail to have the commitment to see their theories through difficult periods. Individual scientists need to have faith that they will persevere in the face of seemingly contrary evidence in order to do the work necessary to defend their theories. Without this bias-laden commitment, good theories would be thrown away prematurely.
Further grasping why scientists, in contrast to their cheerleaders in popular media, would defend bias as often good for science requires recognizing that the faith-based understanding of science is founded upon a mistaken view of objectivity. Far too many people see objectivity as inhering within scientists when it really exists between scientists. As political scientist Aaron Wildavsky noted, “What is wanted is not scientific neuters but scientists with differing points of view and similar scientific standards…science depends on institutions that maintain competition among scientists and scientific groups who are numerous, dispersed and independent.” Science does not progress because individual scientists are more angelic human beings who can somehow enter a laboratory and no longer see the world with biased eyes. Rather, science progresses to the extent that scientists with diverse and opposing biases meet in disagreement. Observations and theories become facts not because they appear obviously true to unbiased scientists but because they have been met with scrutiny from scientists with differing biases and the arguments for them found to be widely persuasive.
Different areas of science have varied in terms of how well they support vibrant and progressive levels of disagreement. Indeed, part of the reason why so many studies are later found to be false is the fact that scientists are not incentivized to repeat studies done by their colleagues; such studies are generally not publishable. Moreover, entire fields have suffered from cultural biases at one time or another. The image of the human egg as a passive “damsel in distress” waiting for a sperm to penetrate her persisted in spite of contrary evidence partly because of a traditional male bias within the biological sciences. Similar biases were discovered in primatology and elsewhere as scientific institutions became more diverse. Without enterprising scientists asking seemingly heretical questions of what appears to be “sound science” on the basis of sometimes meager evidence, entrenched cultural biases masquerading as scientific facts might persist indefinitely.
The recognition that scientists often exhibit flawed and motivated reasoning, bias, personal commitments and the exercise of faith nearly as much as anyone else is important not merely because it is a more scientific understanding of science, but also because it is politically consequential. If citizens see scientists as impersonal arbiters of truth, they are likely to eschew subjecting science to public scrutiny. Political interference in science might seem undesirable, of course, when it involves creationists getting their religious views placed alongside evolution in high school science books. Nevertheless, as science and technology studies scholars Edward Woodhouse and Jeff Howard have pointed out, the belief that science is value-neutral and therefore best left up to scientists has enabled chemists (along with their corporate sponsors) to churn out more and more toxic chemicals and consumer products. Americans’ homes and environments are increasingly toxic because citizens leave the decision over the chemistry behind consumer products up to industrial chemists (and their managers). Less toxic consumer products are unlikely to ever exist in significant numbers so long as chemical scientists are considered beyond reproach.
Science is far too important to be left up to an autonomous scientific clergy. Dispensing with the faith-based understanding proffered by Siegel is the first step toward a more publically accountable and more broadly beneficial scientific enterprise.
