When you can’t just ‘trust the science’
One of many regrettable features of the Donald Trump era is the way that the president’s lies and conspiracy theories have seemed to vindicate some of his opponents’ most fatuous slogans. I have in mind, in particular, the claim that has echoed through the liberal side of coronavirus-era debates — that the key to sound leadership in a pandemic is just to follow the science, to trust science and scientists, to do what experts suggest instead of letting mere grubby politics determine your response.
Trump made this slogan powerful by conspicuously disdaining expertise and indulging marginal experts whotold him what he desired to hear — that the virus isn’t so bad, that life should just go back to normal, usually with dubious statistical analysis to back up that conclusion. And to the extent that trust the science just means that Dr. Anthony Fauci is a better guide to epidemiological trends than someone the president liked on cable news, then it’s a sound and unobjectionable idea.
But for many crucial decisions of the past year, that unobjectionable version of trust the science didn’t get you very far. Andwhenithad more sweeping implications, what the slogan implied was often much more dubious: a deference to the science bureaucracy during a crisis when bureaucratic norms needed to give way; an attempt by para-scientific enterprises to trade on (or trade away) science’s credibility for the sake of political agendas; and an abdication by elected officials of responsibility for decisions that are fundamentally political in nature.
The progress of coronavirus vaccines offers good examples of all these issues.
That the vaccines exist at all is an example of science at its purest — a challenge posed, a problem solved, with all the accumulated knowledge of the modern era harnessed to figure out howto defeat a novel pathogen.
But the further you get from the laboratory work, the more complicated and less clearly scientific the key issues become. The timeline on which vaccines have become available, for instance, reflects an attempt to balance the rules of bureaucratic science, their priority on safety and certainty of knowledge, with the urgency of trying something to halt a disease that’s killing thousands of Americans every day. Many scientific factors weigh in that balance, but so do all kinds of extra-scientific variables: moral assumptions about what kinds of vaccine testing we should pursue (one reason we didn’t get the “challenge trials” that might have delivered a vaccine much earlier); legal assumptions about who should be allowed to experiment with unproven treatments; political assumptions about how much bureaucratic hoop-jumping it takes to persuade Americans that a vaccine is safe.
And the closer you get to the finish line, the more notable the bureaucratic and political element becomes. The United States approved its first vaccine after Britain but before the European Union, not because Science says something different in D.C. versus London or Berlin but because the timing was fundamentally political — reflecting different choices by different governing entities on how much to disturb their normal processes, a different calculus about lives lost to delay versus credibility lost if anything goes wrong.
When we look back over the pandemic era, one of the signal failures will be the inability to acknowledge that many key decisions — from our vaccine policy to our lockdown strategy to our approach to businesses and schools — are fundamentally questions of statesmanship, involving not just the right principles or the right technical understanding of the problem but the prudential balancing of many competing goods.
On the libertarian and populist right, that failure usually involved a recourse to “freedom” as a conversation-stopper, a way to deny that even a deadly disease required any compromises with normal life at all.
But for liberals, especially blue-state politicians and officials, the failure has more often involved invoking capital-S Science to evade their own responsibilities: pretending that a certain kind of scientific knowledge, ideally backed by impeccable credentials, can substitute for prudential and moral judgments that weare all qualified to argue over, and that our elected leaders, not our scientists, have the final responsibility to make.
