The popular slogan today is “Believe in science.” It’s often used as a weapon against people who reject not science in principle but rather one or another prominent scientific proposition, whether it be about the COVID-19 vaccine, climate change, nutrition (low-fat versus low-carb eating), to mention a few. My purpose here is not to defend or deny any particular scientific position but to question the model of science that the loudest self-declared believers in science seem to work from. Their model makes science seem almost identical to what they mean by, and attack as, religion. If that’s the case, we ought not to listen to them when they lecture the rest of us about heeding science.
The clearest problem with the admonition to “believe in science” is that it is of no help whatsoever when well-credentialed scientists–that is, bona fide experts–are found on both (or all) sides of a given empirical question. Dominant parts of the intelligentsia may prefer we not know this, but dissenting experts exist on many scientific questions that some blithely pronounce as “settled” by a “consensus,” that is, beyond debate. This is true regarding the precise nature and likely consequences of climate change and aspects of the coronavirus and its vaccine. Without real evidence, credentialed mavericks are often maligned as having been corrupted by industry, with the tacit faith that scientists who voice the established position are pure and incorruptible. It’s as though the quest for government money could not in itself bias scientific research. Moreover, no one, not even scientists, are immune from group-think and confirmation bias.
So the “believe the science” chorus gives the credentialed mavericks no notice unless it’s to defame them. Apparently, under the believers’ model of science, truth comes down from a secular Mount Sinai (Mount Science?) thanks to a set of anointed scientists, and those declarations are not to be questioned. The dissenters can be ignored because they are outside the elect. How did the elect achieve its exalted station? Often, but not always, it was through the political process: for example, appointment to a government agency or the awarding of prestigious grants. It may be that a scientist simply has won the adoration of the progressive intelligentsia because his or her views align easily with a particular policy agenda.
