Scientists must ultimately address the threat of the virus, but they cannot solve the immediate problem of mobilizing the country against it.
The political-opinion factory has moved from downplaying the coronavirus outbreak to haranguing the president for his alleged dismissal of science. The New York Times’s Paul Krugman charges not just Trump but the Republican Party as a whole with cultivating “an attitude of disdain toward expertise.” Never mind that the president and the media have taken a similar trajectory during this crisis — from dismissal to alertness to panic — while others on the right, such as Tom Cotton, sounded the alarm from the beginning. The underlying assumption that experts alone can resolve this crisis is wrong.
For one, a monolithic expert opinion on the present pandemic does not exist. SARS-CoV-2, the virus that causes COVID-19, emerged only three months ago; scientists haven’t had nearly enough time to conduct conclusive research into it. And constraints on testing, compounded by uncertainty as to the number of asymptomatic cases, make the current medical data largely unreliable.
While some epidemiologists have used previous flu pandemics to inform their thinking, that approach requires rough estimates of factors such as reproduction and fatality rates, leading to wide variance in projections. To take one example, Oxford University researchers found that as much as 40 percent of the U.K. might be immune to the novel coronavirus, while a team from Imperial College London projected more than 250,000 domestic deaths, even under strict social-distancing measures. For all their sophistication, computational tools rely on inputs that are difficult to observe in real time.
